Introduction:
The XTBA DALI Watch is a tester which is designed to simplify DALI
commissioning and/or testing, identify faults, monitor commands and make
life a little simpler. So if none of the below makes any sense - don’t panic as
the XTBA DALI Watch will help you through muddy waters of DALI – it is not
‘Rocket Surgery’.
Welcome to the world of DALI. This lighting control protocol can be
complicated as well as confusing - and sometimes just plain bizarre. To add to
the ‘gaiety’ there are a lot of ‘reserved’ commands and a bunch of ‘application
extended commands’ resulting in not enough command space to fit into 8 bits
so ‘special’ or high commands are needed. They tend to work in a completely
different way to other ‘low’ commands and to each other. There is a full list of
commands and responses at the end of this manual.
The terminology has been kept as close to the DALI standard as possible and
where it can be ambiguous explanations provided.
To simplify the commands, commands OFF (command 0) to APPLICATION
EXTENDED COMMANDS (command 255) are referred to low commands.
Commands from TERMINATE (command 256) to ENABLE DEVICE TYPE
(command 272) are referred to high commands.
DALI also helpfully (as it uses less bits) has a channel/address range from 0
to 63 rather than 1 to 64 and in order to keep as close as possible to the DALI
standard the XTBA DALI Watch sticks to this format. To simplify in day to day
use, the default address loaded on a functions entry is 1 rather than 0, so you
can get to zero (if the mood takes you) by pressing the Down or Left key
depending on function type.
DALI again triumphs when it comes to levels. The allowable range is 0 to 254,
not 255 so in displays that show levels ‘max’ is displayed when the level is =
254.
DALI Data Polarity
Dali receivers will work out their own polarity – so you can attach the two
cables either way.
Advanced Menus
There is a lot the XTBA DALI Watch can do and a lot you might never want to
know about. So in user options you can select Advanced Menus on or off.
With this set off some of the more esoteric functions are switched off in the
menu system to keep them out of the way.
Power Options
DALI Buss Power - Unlike most other protocols the DALI line is continually
powered from a D.C. power supply 9 to 22volts (normally 15volts) called ‘DALI
buss power’ across the data pair. The controller sends information by
switching the positive line low - effectively shorting out the line. The receivers

XTBA DALI Watch Manual Page 4of 26
Product # - 03/2013
© XTBA 1986 – 2013
monitor the line for the data and where required will send information back to
the controller by the same method.
No power supply = no communications!
Power – from an existing DALI Buss Power Supply
The XTBA DALI Watch can be powered from an external PSU (via the power
input socket) or directly from the DALI Buss power – if available.
If the XTBA DALI Watch is powered from the DALI Buss (not from its own
supply) there is nothing more you need to do. If it finds DALI Buss Power it
will turn on, if not it won’t - isn’t technology a wonderful thing!
The XTBA DALI Watch takes about 35ma @15V from the DALI Buss (as you
asked) or with its external supply connected it will draw nothing from the DALI
Buss.
DALI Buss Power from the XTBA DALI Watch
When powered from the XTBA DALI Watches’ external PSU you can add
DALI Buss Power if not available. So fixtures can be simply bench tested,
installations half completed or sections of an installation can be tested without
the need to find another power supply.
How can you tell?
First connect the XTBA DALI Watch to the DALI data pair. When connected to
the DALI system (and in the main menu loop) if the blue led is off the system
already has DALI Buss Power connected. So you can now use the XTBA
DALI Watch.
If the blue LED is flashing quickly there is no DALI Buss Power available so
you will need to add power to the Buss.
Press the Function button until the following displays:
L O C A L B U S S P S U O F F
Y e s t o t o g g l e
Pressing the Yes button will turn on Local DALI Buss Power, the blue LED will
stop flashing the display will change to tell you what the line voltage is, so you
should be ready to go. Pressing the Function button will take you back into the
main menu loop.
If you enter this menu when the unit is powered from external Dali Buss
Power and the Local Buss Power is off the display will change to:
L O C A L B U S S P S U O F F
U S I N G E X T E R N A L B U S S
What you need to avoid is turning on Local Buss Power and then connecting
to the data pair. As you might end up having two Buss Power supplies on at
the same time. This probably won’t do much harm or the Watch will simply
reset back to the main menu with the Local Buss Power disconnected.

XTBA DALI Watch Button Control
The XTBA DALI DALI Watch has five buttons to control its functions as
follows:
Function: Next main menu or if in a sub menu will always take you
back to the top - receive menu.
Menu / Left: Sub menus or left scroll in receive and transmit
Yes / Right: Enter selected menu or right scroll in receive and transmit
Up: Command scroll or level/value up
Down: Command scroll or level/value down
Data, Transmit, Error LED:
If the XTBA DALI Watch is in receive menus the LED will be lit if there is
incoming DALI data.
If the XTBA DALI Watch is in channel transmit menus the LED will slowly
flash
If the LED flashes quickly there is an error e.g. No Buss Power
Shortcuts: When in any of the top menus pressing both the Up and Down
buttons will switch the display between decimal or percent. This setting is not
stored so the XTBA DALI Watch will go back to the setting in user options on
next power up.
In menus where the Left / Right buttons are used pressing both will set the
value to 1. In menus where the Up / Down buttons are used for levels
pressing both together will set the value to 50%
DALI Buss Power Alert:
On entry to functions (except User Options) the XTBA DALI Watch will check
that DALI Buss Power is available. If there is no power the display will change
to:

Pressing Menu when the main menu is displayed will take you into that
functions sub menu. Pressing the Menu button again will then take you
around the sub menu loop. Pressing Yes will then enter that function.
Pressing the function button at any time will take you back to the top receive
menu.
So with Receive Levels displayed pressing Menu button will take you into the
Receive menu loop. Pressing the Menu button again will take you around the
receive loop.

Receive Levels: Pressing the Yes button will enter the receive function. This
allows you to view any DALI levels (arc power commands). Group level
commands are ignored as they have their own menu below. If there is no
DALI being received the Watch will let you know with the message ‘NO DALI
INPUT’.
C H : 1 2 3 4
R X % 0 0 0 0
The upper line shows the channel number and the lower the level received.
Next to the RX is a % symbol if the unit is set for percent or D if set for
decimal (see user options). The RX tells you that you are in receive as the
transmission display looks the same but with a TX.
Use the Left and Right buttons to scroll through the DALI channels.
View Commands Live: (see user options for arc power / level blocking and
repeat command blocking)
The unit will monitor the data line and will display commands received. If level
blocking is enabled only non-level commands will be received. The XTBA
DALI Watch will only display new commands so if a single command is sent
again it will be ignored after the first time unless repeat command blocking is
turned off.
Pressing the Yes button with the View Commands Live menu displayed the
display might look like this once a command has been received.
Command Number address, group or broadcast
C O M N o 0 @ S . A D D 0
O F F
Command Description
On entry any existing command history will be cleared. The top line tells you
the command number and if it is a short address, group or broadcast. If it
receives a group command the top right will change to GROUP with the group
value and if broadcast the top right will change to ALL.
With commands that do not have a short address/group or/broadcast e.g.
some high commands such as Terminate the top right will be blank.
The second line gives the command description. The display will update as
any new commands are received.
View Command History: Command history will allow you to view the last 250
command pairs received. It can be used in two ways. When in ‘View
Commands Live’ pressing the Menu button will enter the history display.

XTBA DALI Watch Manual Page 7of 26
Product # - 03/2013

Pressing the menu button again will take you back to ‘View Commands Live.’
So you switch between the two. If entered from the main menu it will display
the last 250 commands received.
The COM in the top left of the display is replaced with the slot value and the
Up and Down keys can be used to scroll through the history.
History Slot address, group or broadcast
5 N o 0 @ S . A D D 0
O F F
Command Description
If the slot has no command data e.g. beyond the command history the display
will show ‘EMPTY SLOT’.
View Raw Data: The received data is displayed as follows:
S . A D D 0 C o m N o
0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0
=Short address 0 with command 0 (OFF :
The upper line displays the short address, group or ALL for a broadcast
command.
Note bit 0 is set for 1 (the command bit) as OFF is a command, the address is
contained in bits 1 through 6.
If level blocking is turned off and a level is being received the display should
look something like this:
S . A D D 0 L e v N o
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
= Short address 0 at level zero
If the unit is receiving a high command the top left will change to HICOM as
follows:
H I C O M L e v N o
1 0 1 0 0 0 0 1 0 0 0 0 0 0 0 0
= Terminate
Some high commands use the low byte for level/address information, in this
case ‘Terminate’ does not. In either case the second byte is labelled LevNo in
high commands.
Pressing and holding the Yes button when in view raw data will freeze the
display to give you a chance to see what is going on with fast data.

Command Compare:
This function allows a command with either a short address, group or
broadcast to be set up or high commands with or without data in the second
byte. The XTBA DALI Watch will then wait for reception of this exact
command and let you know it has been received.
So if you are wondering why your system does not respond to a particular
command you can find out if it has ever been sent. Or for commands that
need to be received twice to activate a fixture (Commands 32-128, Initialise,
randomise) you can see if they were sent twice, or you could use Command
History.
Pressing the Yes button from Command Compare the display will change to:
C 0 M P A R E U S I N G S . A D D
y e s t o e n t e r o r m e n u
Pressing the Menu button again will loop through the short address (S.ADD)
Group or broadcast (B.CAST). In this way any command can be set up to be
compared.
Pressing Yes will take you into the compare display.
> O F F
A D D R E S S 0
Pressing the Menu button will toggle the left side arrow > to the upper or lower
line. With the arrow in the upper line pressing the Up/Down buttons will
change the command to be compared. With the arrow on the lower line the
address or group
(if set on entry) can be altered.
If the command has no address, group or broadcast e.g. high commands the
display will change. If the command has a value e.g. load DTR then the
display will change and the lower line is then used to set a value.
Pressing the Yes button will take you into the compare display as follows:
> O F F
A D D R E S S 0 1 : 1 4 3
= 1 command found equal to OFF at address 0 in 143 commands
received.
The figure on the left of the semi colon is the number of equal commands
received. The right hand figure is the number of commands received the
range of both is 0 to 255.

Receive Group Levels
This functions as in Receive Levels except arc power levels are ignored and
group levels displayed. Pressing the Yes button will take you into the Group
Level display as follows:
G R P : 1 2 3 4
R X % m a x 0 0 0
In this case group 1 is at full. Pressing the Left/Right buttons will scroll through
the groups 0 to 15.
Flicker Finder:
This function is used to establish if there are any errors in transmission or
intermittent problems and is most usefully used with level commands.
Pressing Yes from the flicker finder menu the display will ask you to ‘TAKE
SNAPSHOT’. Pressing Yes will store the existing data frame on the line and
the display will change to COMPARING DATA.
Incoming address and command or level information is now compared with
the internal memory and if any differences detected the first error detected will
be displayed as follows:
C H A N O R I G N E W
0 3 1 % 2 6 %
In this case address 0 has moved from 31% to 26% during the sample time.

DATA CONFLICT ALERT
The XTBA DALI DALI Watch is designed to be both a DALI
programmer/tester and a DALI monitor. In an installation it is possible that
there is another transmitting device in use so if you try to transmit the Watch
will warn you that there is already something transmitting as follows:
D A T A C O N F L I C T A L E R T
y e s = s e n d o r f u n c t i o n
Pressing Yes will start the transmission but the data may be corrupted e.g.
drink too much and try to bribe public officials. Pressing Function will escape
to the main menu loop.

Adjust single levels: Pressing the Yes button will enter the function and the
display will change to: This allows you to alter any DALI level.
C H : 1 2 3 4
T X % 0 0 0 0
The upper line shows the channel number and the lower the level transmitted.
Next to the TX is a % symbol if the unit is set for percent or D if set for decimal
(see user options). The TX tells you that you are in receive as the receive
display looks the same but with a RX.
Use the Left and Right buttons to scroll through the DALI channels.
The first channel on the left is the channel that you have command of.
Pressing the Up/Down buttons will alter the level at that channel number. So
by using the Left/Right Up Down you can control all 64 channels. Note in this
mode the Watch transmits all 64 channels and as DALI is not a quick protocol
(not even close) there will be a delay from the display and the fixture getting to
that level.
Adjust One Level: Pressing the Yes button will enter the function and the
display will change to: This allows you to alter all DALI levels to quickly find a
fixture.
A D D R E S S 1 T O 0 %
L / R = A D D U / D = L E V E L
Pressing the Left/Right buttons will alter the address setting and the Up/Down

Quick Set Up
In order to set up DALI fixtures values need to be transferred to the data
transfer register before the set up command transfers the value to the relevant
device slot and all commands sent twice in less than 100ms. This would take
some speedy finger action so the XTBA DALI Watch deals with all of this for
you so you don’t need to bother.
Pressing the Yes button the display will change to:
S E T U P A T S H O R T A D D R
Y e s t o e n t e r o r m e n U
Pressing the Menu button again will loop through short address (S.ADD)
Group or broadcast (B.CAST). This allows all types of set up. If broadcast is
selected the XTBA DALI Watch will display ? SET UP ALL DEVICES? To
warn you that you are about do globally change all connected devices.
Pressing Yes will take you into set up display.

With the arrow > on the upper left of the display the Up/Down buttons control
which command to be sent. Commands available are: Set Maximum Level,
Set Minimum Level, Set Failure Level, Set Power On Level, Fade Time, Fade
Rate.

Pressing the Menu button will move the arrow to the lower left. This allows the
Up/Down buttons to control the address or group. (If in broadcast the address
will be ALL so the arrow will move directly to the level setting). Pressing the
Menu button again will move the arrow next to the @. The Up/Down buttons
can now be used to set the level to be sent.
Once you have set up the command, address and level press the Yes button
and the command will be sent. The display will show ‘CONFIGURATION
SENT’ before returning back to the quick set up display.
Advanced Set Up
Advanced Set Up lets you control the DALI installation directly. All commands
are available but you will need a working knowledge of DALI to get the most
out of Advanced Set Up. To help the Watch will send all double commands
automatically (see below). Pressing the Up/Down buttons together will jump to
command 257 Load Value to the DTR. Remember to Initialise if using
commands 259 to 270!
Pressing the Yes button the display will change to:
S E T U P A T S H O R T A D D R
y E s t o e n t e r o r m E n u
Pressing the Menu button again will loop through short address (S.ADD)
Group or broadcast (B.CAST). This allows all types of set up. If broadcast is
selected the Watch will display ? SET UP ALL DEVICES? To warn you that
you are about to globally change all connected devices.
Pressing Yes will take you into the advanced set up display

With the arrow > on the upper line the command list can be scrolled through
using the Up/Down buttons. Pressing the Menu button will move the arrow to
the lower left. The Up/Down buttons can now be used to alter the address or
group to be sent to or in the case of some high commands alter the value or
address.
The DALI commands have different possible functions. Commands 0 to 128
simply use the address and do not expect and answer. The other low
commands use the address/group/broadcast but can ask for status, group.
Yes/No answers, value or level. All the ‘reserved’ commands and the
‘application extended commands’ are missed out.
As the command list is scrolled through the display will show which type of
command and the expected answer (if there is one) for example:

XTBA DALI Watch Manual Page 13 of 26

> Q U E R Y P O W E R F A I L U R E
A D D R E S S 1 Y / N
= Query Power Failure at address 1 with a YES/NO answer.
Once you have set up the command, address and level press the Yes button
and you will be prompted to send the command. Pressing the Yes button
again and the command will be sent. The display will then show
‘CONFIGURATION SENT’ before returning back to the quick set up display.
Once the command has been sent the answer (if there is one) is displayed on
the lower right of the display, formatted to that answers type. Levels can be
displayed as decimal or percent, values 0 – 255, short address 0 – 63 etc.
If the command expects and answer the answer type is indicated by the lower
right of the display as follows:
Y/N YES or NO request
STA Status request
GRP Group requested
S.A. Short Address requested
FAD Fade time/rate
VAL Value requested
LEV Level requested
The DALI protocol does not differentiate between data types returned it is just
an single byte of data. But in order to make the information clearer the Watch
will show which type of data requested is returned. For example if Query Max
Level is set the answer will be displayed as LEV as it is a level. If Query
Random address the answer will be displayed as VAL as it is a value.
YES/NO Beware the YES/No requests. If a YES/NO request is sent and the
answer is YES the device will return 0xFF/d’255’. If the answer is No nothing
happens. So a request for Query Lamp Failure with the answer NO tells you
that there is no problem at that address or alternatively that address does not
exist.
Initialise Command
The initialise command uses the full address range 0 to 63 but in addition has
two additional address functions. The XTBA DALI Watch places these two
functions above address 63 as below. So to get to the these two possible
initialise parameters press the Up button.
NSA = (no short address) devices without a short address will be initialised.
ALL = All devices will be initialised.
Double send commands:
Configuration Commands 32 to 128 and Initialise or Randomise are required
by the DALI standard to be sent twice to be executed by the receiving fixture.
The XTBA DALI Watch automatically sends these commands twice when the
command is sent unless disabled in Development Options.

Discover/Program All
Before a DALI installation can be fully used the devices need to have their
short address set, (but you knew that). DALI fixtures do not have address
switches so the only way to set the address is using a programmer.
Fortunately you have one.
Pressing yes with the display in Discover/Program All the display will change
to:
W I L L E R A S E A L L D A T A
y e s o r f u n c t i o n = e s c
This is warning you that you are about to do something drastic. If you press
Yes all connected fixtures will be reset and any existing short address
removed. The display will show ‘ERASING DEVICES’ and count up from 0 to
63 the display will then briefly change to LOADING DEFAULTS where all
fixtures are programmed as follows: Power On Level = 1, Minimum Level = 1,
System Failure Level = 0, Max Level = 254. Following discovery you can
change these settings in Quick Set Up if needed.
Once the defaults are set the display will change to:
S E A R C H I N G D E V I C E S
2 5 4 1 2 3 0 2 1
On the lower line you will see the search address being scanned through. In
reality this tells you next to nothing but at least you can see something is
going on and is fun to watch. Once a device has been discovered that fixture
will light to the ‘display find’ value (set in user options- default 50%) so you
can see which it is and the display will change to:
S . A D D R E S S = 1
m e n u = r e j e c t y e s
=
s e n d
If you are not sure what address to program pressing Menu will remove the
fixture form the discovery process and not program the address. You can then
run Discover New at a later time to assign that fixtures address.
Or:
Using the Up/Down keys the fixtures address can now be assigned. Pressing
Yes will program that fixture to the short address selected and will display
PROGRAMED AND VERIFIED if successful.
Following this the Watch will now search for the next unassigned fixture to
program. Once the fixture has been identified and lit it can now have its short
address assigned using the Up/Down keys. If a fixture has already been
assigned a short address USED will appear on the to right of the display to
warn you that you are about to assign another fixture to an address that is
already in use.

XTBA DALI Watch Manual Page 15 of 26
Product # - 03/2013
© XTBA 1986 – 2013
Once all connected devices have had their short address set the display will
change to:
C O M P L E T E 1 0 F O U N D
f u n c t i o n t o e x i t
In this case 10 devices have been discovered and programed successfully.
Pressing the Function will escape back to the main menu loop and terminate
the discovery process.
Use of address zero
In order display the fixture that you are about to program, the XTBA DALI
Watch temporarily uses address zero to light up the fixture before you assign
it to its new address. If when programming you set an address to zero it will
be lit along with the next discovered address, which might get confusing.
To get around this when a fixtures appears that needs to set to address zero
simply press the Menu button. That fixture will be turned off and removed from
the discovery process. Once all other addresses have been set (address 1
through 63) run Discover New. The remaining fixtures will be discovered and
as they are the only ones remaining can all be programmed to zero.
Discover/Program New
If new fixtures are added to an existing system their short address can be
assigned without the need to go through the entire discovery process.
Pressing Yes when the Discover/Program New is displayed will enter new
device search. If new devices are found the Watch will switch into program
mode (as in Discover/Program All) and the new devices short address can be
programed.
Existing programed devices will be ignored except the USED display will still
show if the short address is already in use.
The Discover/Program New looks for devices without a short address. So if
the new fixture added already has a short address the display will show NO
DEVICES FOUND. In this case you will need to use remove the short address
to clear that address and then run Discover/Program New again or use the
patch.
Note: Discover New does not automatically set the fixtures defaults (unlike
discover all) so following discovery you will need to use Quick Set Up to load
the default values.
Patch Devices
This function allows the short address to be altered once set. The Watch will
tell you which fixtures are in use and which short address is free. Pressing
Yes with the Patch Devices displayed the display will change to:
> F I X T U R E @ 1 A C T I V E
T O S . A D D 3 U S E D

The top line displays the fixture to be changed. The lower line displays which
short address it is to be changed to.
In this case the fixture with short address 1 is to be changed to short address
3.
The right side of the display shows if the device you are attempting to patch is
Active (e.g. connected) the lower line shows if the short address you are
going to change it to is in use. The right hand side of the display will be blank
if the fixture is not active or the address is not in use.
Pressing the Menu button will toggle the left hand side arrow to the top/bottom
line of the display. With the line on the top or bottom of the display the short
address can be altered by use of the Up/Down buttons.
With the arrow on the lower line pressing the Yes button will send the patch
change to the addressed device and SENT will appear in the lower right of the
display.
Any active fixture will be lit to the ‘display find’ value (set in user options) when
the arrow > is toggled. On the upper line the address of the fixture to be
changed will be lit and when the arrow moves to the lower line the address to
be change to will be lit – if connected.
Remove Short Address
If there are two fixtures on an address that need to be on different addresses
this function allows the address to be removed, as there is no other way to
separate the fixtures. Following the addresses removal Discover New can be
run and the discovered devices (now with no address) programed. Pressing
the Yes button the display will change to.
R E M O V E S . A D D @ 1
u p / d o w n , y e s t o s e n d
Using the Up/Down buttons the short address to be removed can be altered.
The fixture at that address will be lit to the ‘display find’ value (set in user
options). Pressing the Yes button will send out the command and the display
will show ‘Configuration Sent’. Once removed the fixture will be reset to its
internal default settings.
Set Up Scenes
This function allows scenes to be programed quickly. Pressing the Yes button
the display will change to:
> S E T S C E N E 1
T O L E V E L 0 %
With the arrow on the upper line the Up/Down buttons can be used to alter the
scene number (0 to 15). Pressing the Menu button will move the arrow to the
lower line. The Up/Down buttons can now be used to set the scenes level.

Pressing the Yes button will send out the setting. e.g. load the DTR and
transfer it to the scene memory.
Check Fixtures
This function is a quick check if the fixtures defaults on systems where all the
defaults are supposed to be the same. On pressing the Yes button the display
will change to:
S . A D D 0 N A
And the address will begin to count up. If no address is found the display will
show ‘NA’. If found the display will show ‘OK’.
The XTBA DALI Watch scans the fixture list and looks for the first valid
address. It then records the Max Level, Min Level, Power On Level and
System Failure Levels and compares the values against any other available
fixtures. If it sees a difference the display might change to:
S . A D D 5 M A X L E V E L
y e s T o c o n t i n u e
In this case address 5 has a different max level. Pressing the Yes button will
continue the search.
At the end of the search the display will change to:
8 D E V I C E S F O U N D
f u n c t I o n t o e s c a p e
This will display the number of valid addresses found
So you can tell how many active devices are on the system and if they are set
up to the same defaults. If any differences are found you can use Quick Set
Up in broadcast to ensure they all have the same defaults.
Query Devices
Pressing Menu when Query Devices is displayed will take you into the main
display. This is quick method of finding settings at an address. Alternatively
you can use Advanced Set Up to do much the same thing but this groups the
common commands into a simple menu loop. See also YES/NO note in
advanced.
? M A X L E V @ 1 9 9 %
m e n u = l a s t y e s = n e x t
The Up/Down keys can be used to alter the short address. The Menu and Yes
buttons will take you to the last/next query function. Functions as follows:

Once selected the Watch will continually send the query command and the
answer will be displayed in the top right. Answers will be Yes and No, levels
will be displayed with ‘D’ or % and values. If a level or value is expected ‘NA’
will be displayed if there is no answer.

Device Response Time
The DALI Parameters can display numerous timings of the DALI being
received. Pressing the Yes button with bit time displayed the display might
look like this:
Bit and Word Time
B I T T I M E W O R D T I M E
8 4 0 m s O K 1 4 . 0 m s O K
On the right of the value will be OK if the time is in range or ERR if out of the
DALI specification.
Bit Time
The DALI protocol uses bi phase encoding so it is difficult to measure the full
bit length in a data stream. The Watch measures the half bit time and
presumes that the second half of the bit is the same time as the first. One can
only hope. Range is 750us to 916us (833us +/- 10%).
Word Time
The word time is calculated from the falling edge of the start bit of the word
pair (address and command byte) to the rising edge of the first stop bit, 18 bits
in total.
The stop bits are not counted as part of the word as you can’t count what
doesn’t change. So the range is 13.5ms to 16.5ms (18 x 833us +/- 10%)
When in a Parameters pressing the Menu button will take you to the next
function.
Interbyte Time Interbyte time in ms:
D A L I I N T E R B Y T E T I M E
1 2 . 6 m s

XTBA DALI Watch Manual Page 19 of 26

Word Range is the number of DALI words being received
D A L I W O R D R A N G E
L = 0 H = 6 3 N U M = 6 4
L = Lowest address received. H = Highest address received and NUM
= number of addresses.
Frame Time C1 to C1 is the time between channel one being received again
e.g. the total frame length in seconds.
F R A M E T I M E C 1 t O C 1
1 . 7 0 s e c o n d S
Framing Errors is the number of incorrectly formatted DALI words – hopefully
none.
Input Voltage
The DALI buss power is monitored during the interbyte time to give the high
value and during a low bit to give the low value. The high value should be
between 9.5 to 22 volts and the low value should be between 0 and 6.5 volts.

Device Response Time
With no DALI being received entering parameters will prompt you to enter the
device response time, ‘menu for response’.
R E S P O N S E @ S . A D D 1
W A I T I N G F O R R E S P O N S E
Using the up/down keys to change the address setting if a response is
received at an address the blue led will flash and the display will change to:
R E S P O N S E @ S . A D D 1
1 0 . 6 m s I N R A N G E
The XTBA DALI Watch sends ‘query ballast’ to the address and monitors the
response time. If the response is started less than 6.4ms or greater than
21ms the display will show ERROR. If between 6.5ms and 20ms ‘IN RANGE’.
If no response found (e.g. no fixture found) the display will show ‘WAITING
FOR RESPONSE.’

Pressing the Menu button will take you through the Options loop. User options
are stored by the XTBA DALI Watch on exit of the User Option Menu.
Display in Percent: Pressing the Yes key toggles between the decimal
display values (0 to 253, max) or percent values (0 to 98, max).
Level Commands: Pressing the Yes key toggles between on or off. If level
commands are set off the Watch will ignore any level (arc power) commands
in View Commands Live, Command History, Raw Data.
This filters out the level commands so if configuration commands are
interleaved with level commands they can be detected more simply and
device history will not be filled with a load of short addressed level commands.
Block Repeat Data: Pressing the Yes key toggles between on or off.
If set on when in advanced commands only new data will be stored into
memory.
Display Find: Sets the level the fixture will be lit to in discovery, patch,
remove address etc. – range 0 to 100%.
Advanced Menus: Pressing the Yes key toggles between on or off.
With Advanced Menus set to off some of less used DALI functions are
removed from the DALI menu loops.

Development Tools
Double Send Comms: Pressing the Yes key toggles between on or off.
The DALI standard requires that commands 32 to 128, randomise and
initialise need to be sent twice within 100ms. So this should normally be set
for ON and the XTBA DALI Watch will send them out as required. Turning
them off allows for testing of devices to ensure they do not respond to single
commands.
