Hardware installation
The Relay – 8 is designed to be mounted in a rack or as a stand-alone unit on a desk, drawer or
alike.
Make sure there is at least 40 mm of free space above the unit as air circulation around the unit
is needed for reliable performance. If installed in a closed environment forced air circulation may be
needed.
Mounting the unit in a 19” rack
The Relay – 8 can easily be installed in a 19” rack.
Due to the standard 1U height, low weight and small mounting depth the Relay – 8 can be
mounted from the rack front without the use of a rack shelf or supporting rails.

individual relay. Use the supplied cable relief brackets to
fix the cables with a cable tie to prevent accidental
disconnection of the cables. See section Mount cable
relief bracket and covers on page 6.
If you want to connect and switch AC power for your
external equipment in an easy and convenient way use
the Neets IEC Mains Adaptor (306-0015) (sold
separately) instead of the terminal block and cable relief
brackets.
RS-232/IR ports
The onboard RS-232 ports (T1, R1, T2, R2) can be used for one- or two-way communication. Both
of the RS-232/IR ports can be used as either as RS-232 or as IR emitter.
On the front of the Relay – 8 you will find 2 led for each RS232/IR port. When the Relay – 8 is
sending data on a RS232/IR port it’s green tx led will light. When the Relay – 8 is receiving RS232
data the orange rx led will light.
Digital I/O
The Relay – 8 has 8 x I/O (Inputs/Outputs) available. They
can be used for an external control keypad, PIR
(movement) sensor, keyboard lock, extra relays, or other
compatible uses. The ports are not potential free; you
may need external relays if you need to prevent ground
loops.
Neets IEC Mains Adaptor
When used as single IR port:
Connect the IR emitter to
T1 (white striped wire) and
GND, as shown above.
When used as RS-232
transmit port: Connect the
device to T1, R1 and GND,
as shown here above.
When used as dual IR port:
Connect the IR 1 emitter to
T1 (white striped wire) and
black wire on IR 1 emitter to
IR 2 emitter (white striped
wire), and black wire from IR
2 emitter to GND, as shown
above.

When used as outputs, the ports are active low. When
indicated as active, the pins are tied to GND through a
FET transistor (also called open drain/collector function).
Each can draw up to 24VDC/500mA.
For each output pin there is a led on the front of the
Relay – 8. The led are on when the output pin is activated
(The output pin is connected to GND)
When used as inputs the voltage has to be below 1 Volt
DC to be accepted as LOW, and above 4 VDC (but below
24 VDC) to be accepted as HIGH. The inputs are de-
fault HIGH and must be connected to ground in order to
change state.
For each input there is a led on the front of the Relay – 8.
The led indicates the current state of the input. When
the led lights orange it indicate that the input is high,
when the light is off the input is low.
LAN
The network connector integrates the system into the
local area network.
There are two LEDs on the connector with the following
indication:
Color Off On Blink
Yellow No Link Link Activity
Green 10Mbit 100Mbit
Front panel USB
The USB port (labeled “config” on the front) can only
be used to firmware upgrade the Relay – 8 through a
Windows/MAC/Linux computer. See the section How to
upgrade the Firmware on page 11 for details.
You are not able to configure or control the Relay – 8
through this port. Do not connect any other devices
to this port. The USB connector for connecting to the
Relay – 8 is type “mini USB B 5P”.
You can buy this cable on the web (buy a USB A to Mini
USB B 5P).

How to connect…
Connecting the Relay – 8 to the control system.
Using I/O pins
If you want to control one or more relays from a digital output, like any of the Neets Control system
range provides, you can do this. By default the Relay – 8 is configured to link the I/O pins to the re-
lays. This means that you can connect the I/O of the Neets Control system directly the Relay – 8.
Not using a Neets Control system to control the Relay – 8 ? Our I/O can interface with all system
that can pull the Input low. To test this simply make a short circuit between the I/O pin and GND
to active the relay.
If the Relay – 8 has been used before it is recommended to reset the Relay – 8 to make sure that
no settings that prevents this operation are saved in the unit (See section page 13).
Using RS232
When controlling the Relay – 8 by RS232 you have to connect the RS232 port from the control
system to the Relay – 8 RS232 port 1 (T1,R1 and G).
The command that has to be sent can be found in the section on page 14.
Remember, controlling Relay – 8 by both RS232 and LAN is not possible at the same time.
Page 13 of 24
Using LAN
Controlling the Relay – 8 can also be done over LAN. This
is done by creating a TCP connection from the control
system to the control port (Default 5000).
The protocol that is used to control the Relay – 8 over
LAN is the same as used when controlling it by RS232.
See the section on page 14. When connecting to the
Relay – 8 control port, the RS232 control on RS232 port
one is disabled.
Controlling an electrical screen or lift
The Relay – 8 offers you the possibility to control up to
four electrical screen and lift directly by 240VAC. When
controlling electrical screen and lift we always recom-
mend that you use two relays. One relay for screen up
and one relay for screen down (In a configuration called:
mutual blocking). Here you can see how to connect your
screen to the Relay – 8.

When making the above configuration you add an extra safety level to your installation. The mutual
blocking prevent that power can be connected to both up and down at the same time.
How you control this configuration depends on the way you connect it to you control system. In
the previous three sections, you can find information on the three types of control you have.
How to control Switching Relay – 8 through USB
After Project Designer 1.6.4 it is possible to control and configure the Switching Relay - 8
through USB the same way you do today with RS232.
When connecting the Switching Relay - 8 to your computer it will be installed as a RS232 port
on your system (The Windows driver is already included in the Project Designer software). Choose
your favorite hyperterminal program or simply open the device driver in the Device Editor and use
it to send the commands.

By default, a RS232 line only allows you to be connected to a single receiver. But with the Relay –
8 you can control multiple units with just a single RS232.
So how do we do this?: Each Relay – 8 can be assigned a id number (Default 1) that allows you to
define what unit a command should be handled by.
If the Relay – 8 device a command on Tx1 that has a id number different from itself, it will
re-transmit the command on Tx2.(This function is called RS232 loop-through)
So adding a second Relay – 8 on the first Relay – 8 Tx 2 will allow you to control this. This is called
daisy chaining the units.
Remember to assign different ID number to each of the Relay – 8 you are using in this constella-
tion. See page 12 for details on how to change the id. Using the same ID number on multiple units
will result in only one Relay – 8 will react to the command and not all with same id number.

Change the ID number of the
relay box
When controlling the Relay – 8 by the External protocol
by ether RS232 or LAN the unit has a ID number that
must be used in the command that are send to it. By
default the Relay – 8 has address 1.The address can
either be changed by RS232, LAN or the test button on
the front of the unit.
To change address of the Relay – 8, see the command
UNITID in the protocol list. Changing the address of the
Relay – 8 on the front of the unit is done like this:
• Connect power to the unit.
• Within 5 sec, press one of the test button and hold it
until its LED lights up.
When the Relay – 8 is powered up, it shows it’s current
address on the relay status LED. LED 1 = address 1,
LED 2 = address 2 …. (While the unit address is
displayed the power on LED is blue.)
If no LED is on, that indicates that the unit has an
address that is not in the range 1-8. The address can be
given any address using the UNITID command on ether
RS232 or LAN.

Reset the unit to Factory default
You can at any time press and hold the relay 1 and 8 test button in for 5 sec. The unit will reboot
and assume the factory settings.
It is also possible to reset the Relay – 8 using the command RESET. See the protocol list for
details.
After resetting the system, it has these settings:
• I/O is set to inputs and controls the relays (I/O 1 ->relay 1, I/O 2 ->relay 2).
• RS232 port 1: 19200 8N1, ready for loop-through.
• RS232 port 2: 19200 8N1.
• IP Address: 192.168.254.252.
• LAN control port: TCP, port 5000.
• LAN to RS232 port 1: TCP, port 5011.
• LAN to RS232 port 2: TCP, port 5012.
• Neets LanBus: Multicast address: 224.10.10.25, port 7979.
Error indication
If there is an error in the system, it will be displayed on the front of the Relay – 8.
On error the power led will flash red.
The above led is ashing.
Unexpected Error Turn off the power to the
control system for 20 sec
before turning the power on
again.
If the error is not resolved,
contact Neets or your local
distributor.
RS-232 and LAN protocol
Controlling the Relay – 8 over RS232 or LAN is done with the same protocol.
If you are using a Neets Control system there is a Device Driver available which provides you with
all the commands below. Open the Device driver in the Neets Device Editor and use the “play”
function on each command gives you an easy way of setting up and configuring the Relay – 8 from
your computer.

Communications parameter
Default RS232 settings:
Baudrate: 19.200
Databit: 8
Stopbit: 1
Parity: None
Default LAN settings:
Network Protocol: TCP
Control port: 5000 (Only one active connection at a time)
LAN to RS232 port 1 gateway port: 5010 (Only one active connection at a time)
LAN to RS232 port 2 gateway port: 5011 (Only one active connection at a time)
Control from the RS232 port is enabled by default. When connecting to a LAN control port the
RS232 ports converts to LAN-RS232 gateways and they can not be used to control the Relay -
8. The only way to get back to RS232 control is by cycling power.
Command
When entering all the commands in the Neets Device Editor software, select “Chr/ASCII” as input
format. To understand the commands below please keep this in mind:
Symbol: Description:
<A> When constructing the command, this part must be replaced with a
sting or number.
<B> When constructing the command, this part must be replaced with a
sting or number.
\CR Every command line must end with a carriage return.
Carriage return is commonly referred to as “CR” or if you need to enter
it in hex, the value is 0D and in decimal, it is 13.
“,” or , When making a command it consist of several parts.
Each part is separated with a comma.
E.g. NEUNIT=1,RELAY=1,ACTION=SET,TIME=10.5
Please be aware that all the RS232 commands are case sensitive. If the Relay – 8 detects an
error in the command line, the entire command will be ignored.
Sending multiple commands is possible without time delay between commands. Just remember
that each command must end with \CR.
If you are looking for a complete list of commands already made, look at the premade device driver
found in the Neets device driver library.
Saving the settings. When adjusting the settings of the Relay – 8, it is important
to save the settings that you want the Relay – 8 to use after the next power
cycling. This is done with the save command. You can nd more information
regarding the save on page 15.

Example
Below you will find a few command that can control the Relay – 8. The below command are just a
few examples to show you how the interface are working. For more details on the command go the
next sections.
Examples of command than can be send on ether RS232 or LAN.
e.g: NEUNIT=1,RELAY=1,ACTION=SET\CR
Reply: NEUNIT=1,OK\CR
e.g: NEUNIT=1,RELAY=1,ACTION=? \CR
Reply: NEUNIT=1,RELAY=1,ACTION=RELEASE\CR
Global functions
In the global functions you find all the functions that allows you to adjust the basic functions of
the Relay – 8. Normally the functions are used while setting up the system. If you wish to use
these settings after a power cycle of the Relay – 8 please remember to use the save command.
Below is the settings for the global functions, for all commands it is mandatory that the start of
the sequence look like this: NEUNIT=<A>,
Where <A> as default is 1. All commands must be started with a “,” and all lines must end with
a \CR
Description: Syntax <A> Default <A> R/W
Save the current settings as
the default startup values.
SAVE=TRUE W
Restore factory defaults values
for the entire system.
FACTORYDEFAULT=TRUE W
Set all the values to their default
(last saved).
This is done by re-booting the
unit.
RESET=TRUE W
Get/set unit ID
You can set the unit id number
either at the front of the unit
using its relay test buttons. See
general manual for the unit for
more details. The ID that can be
assigned on the front are: 1, 2,
3 ….8
By RS232 or LAN you can define
any id that you want as long as
they are no longer that 9 ascii
charaters.
e.g.:
NEUNIT=1, UNITID=Neets1\CR
NEUNIT=1, UNITID=RoomA\CR
UNITID=<A> Up to 9
character
long.
1 R/W
Unit, SN UNITSN=<A> xxyyzzzzz R
Unit software version SWVERSION=? x.y.z R
Example of use: NEUNIT=1,UNITID=23\CR <- Set the ID number of the unit to 23.

LAN Settings
In the LAN Settings you find the settings to set the LAN parameter for the unit. Remember that
if you want the unit to use the current settings at next power up, you have to send the save
command.
Below are the settings for the LAN port. For all commands the mandatory start sequence look like
this: NEUNIT=<A>,SETTINGS=LAN.
Where <A> as default is 1. All commands must be started with a “,” and all lines must end with
a \CR
Description: Syntax <A> Default <A> R/W

changing this value, it
must also be done on all
other system this unit
must communicate with.)
After changing the
multicast address
remember to send the
save command in order
to make sure that the
system uses this
address at next reboot.
MULTICASTADDRESS=<A> xxx.xxx.xxx.xxx 224.10.10.25 R/W
Set the multicast port
the unit must use when
communicating with
other Neets units by
LAN. (Remember when
changing this, it must
also be done in all other
systems this unit must
communicate with.)
After changing the multi-
cast port, remember to
send the save command in
order to make sure that
the system uses this port

Relay control
When controlling the relays you can do simple things like “Set”, “Release” and “Toggle” the relays.
You can also do more advanced things, like delaying the execution of the command and setting the
time that the “Set” function should apply.
Below is the possible settings of relays. For all commands, the mandatory start sequence look like
this: NEUNIT=<A>,RELAY=<B>
Where <A> as default is 1, and <B> is the relay you want to control. All commands must be
started with a “,” and all lines must end with a \CR
Description: Syntax <A> Default <A> R/W
Control the relay ACTION=<A> SET, RELAESE
or TOGGLE
RELEASE R/W
Delay before execution of
action (Start delay)
DELAY=<A> 0-6500.0 0 W
Time (chances the action
from latch to momentary
in this time)
TIME=<A> 0-6500.0 0 W
Example of use:
NEUNIT=1,RELAY=1,ACTION=SET,TIME=10.5\CR <- This command sets relay 1 in 10.5 seconds.
To get the current status of a relay use this command:
NEUNIT=1,RELAY=1,ACTION=?\CR
Reply:
NEUNIT=1,RELAY=1,ACTION=RELEASE\CR
Screen control settings
The screen control offers you an easy and safe way to control electrical screens and lifts using 2
relays or I/O. When combining 2 relays in screen mode, you define the screen up and down time
once. After this you simply send command indicating the direction the screen should move.
The Screen mode ensures that the 2 relays or I/O in no way can be activated at the same time.
Below are the settings for the screen control, for all commands the mandatory start sequence
look like this: NEUNIT=<A>,SETTINGS=SCREEN,SCREEN=<B>.
Where <A> as default is 1 and <B> is the number of the screen you want to configured. All com-
mands must be started with a “,” and all lines must end with a \CR.
