DT-203P, DT-105P and DT-110P display series
1INTRODUCTION
The message displays of DT-105P, DT-110P and DT-203P series are industrial displays of
parallel control.
The displays working order is basically based on a microprocessor and on technically
advanced circuits of control.
Its main characteristic is the great size of the characters.
30mm. height for DT-203, which allows a reading up to 15 meters
50mm. height for DT-105, which allows a reading up to 25 meters.
100mm. height for DT-110, which allows a reading up to 50 meters.
They are manufactured in one or two sides of displaying, which provide several possibilities
and solutions when it has to be installed.
They can be set up on a surface, whether they are fixed to a wall or a partition, or they can be
left hanging from the lateral supports.
There is a wide range of applications of these displays, which goes from industrial
applications, such as warning breakdowns or displaying production information, to common
advertisements.

INSTALLATION
3-1
DT-203P, DT-105P and DT-110P display series
3INSTALLATION.
The installation of the DT-203, DT-105 yDT-110, is not particularly delicate but some
important considerations must be taken into account.
It must not be anchored to places subject to vibrations, nor should it be installed in places
which generally surpass the limits specified in the display characteristics, both in terms of temperature
and humidity.
The degree of protection of displays DT-203, DT-105 and DT-110 is IP41, meaning that they
are protected against penetration by solid foreign objects of a diameter of about 1mm and against the
vertical fall of water droplets. The DT-203f, DT-105f and DT-110f are IP54, which mean that are more
protected. DT-203e, DT-105e and DT-110e are IP65.
Displays DT-203, DT-105 and DT-110, should not be installed in places with illumination level
higher than 1000 lux. Neither should the display be placed in direct sunlight as visibility would be lost.

4OPERATION
4.1 Initial Start Up.
Before connecting the display to the network, we must ensure that all of the connections have
been carried out correctly and that the display is firmly in place.
Every time the display is connected to the power supply there is an initial reset, which checks
all points of the display. After the initial reset the version code is displayed.
Following the initial reset, the display reads the message memory and initialises the messages
table. The word “INICI” is shown until the display is prepared to receive messages.
When the initialisation process is finished, the display is ready to receive data. While waiting
for the first message the display shows a programmed message on the memory.
4.2 Message programming.
In order to program the messages in the memory Eeprom, a PC and the TDLWin Version later
than 1.5, specifically designed to program the messages into the display. Usually you may program
only the message 0 because after initialisation this is the message displayed.
To program the messages, you must program the following parameters:
oDisplay : Parameter Protocol = TDL
oLocal Port = 10001. Use Device Installer software to modify.
oSoftware TDLWin
oSerial line = TCP/IP
oIP Address = Display Address.
4.3 Set parameters.
Before using the display the user must set the parameters:
The parameters are:
1.- Language.
2.- Display address.
3-- Protocol.
4.- Baud rate.
5.- Data length.
6.- Parity.
7.- Stop bits.
8.- Serial input.
9.- Date
10.- Time
11.- Brightness.
12.- Position of the connectors.
13.- Text scroll speed.
14.- Exit
To set the parameters, the display has a pair of pushbuttons located at the bottom of the case.
The menu is in four languages.

4.4 Internal working order
Although it is not necessary to know how the internal working order operates, it is interesting
to know its composition and structure in order to know better how to work with it.
DT-105P, DT-110P and DT-203P displays can store up to 512 messages, with a maximum
length of 160 characters per message. The sum of all the characters of all messages cannot be more
than 32000 characters.
Every message is composed by two blocks:
*Message number -It takes two characters. It is the number to be used to call the message
from PLC
*Printing message code- It takes one character. Not used now.
*Message characters- It takes one character.
*Control orders - It takes two or more characters.
They indicate the special functions which the message must do when they are displayed. The
orders used are:
- Number of line- It takes three characters.
- Start of characters in flashing - From this code on all the characters are displayed in
flashing mode to the end of the message or until ending of flashing code is used (It takes two
characters).
- End of characters in flashing- From this code on the characters are not in flashing method
anymore.
External variable. It saves one character from the text to enter an external variable (it takes
two characters). In message memory one external variable takes two characters. However, the
following variables of this message, if they are correlative, take only one variable.

- Internal variable. Hour: Minutes. It saves 5 characters from the text. When the display
shows this variable, it sets automatically the present time in Hour: Minutes format (It takes two
characters).
- Internal variable. Hour: Minutes: Seconds. It saves 8 characters from the text. When the
display shows this variable, it sets automatically the present time in Hour: Minutes: Seconds format (It
takes two characters).
- Nº of message internal variable. It adds the message number to the text. It saves three
characters (It takes two characters).
- Message lasting time. It does not save any characters from the text. It is the time of period
that the message last. Once the lasting time of the message is programmed, this value is not changed
until another message, which is programmed with message lasting time order, is operated (It takes 4
characters).

4.6 How to send messages to the display
There are three ways to send a message once the displayed is programmed:
- Displaying only one message
- Displaying all messages in EEPROM
The number of lines of a message has nothing to do with the way a message is sent
because the corresponding lines and texts are defined by the message edited in
TED program.
All the following specifications have nothing to do with the number of lines of the display
4.7 General specifications for working with the variables.
To display variables, there are some conditions to consider:
-The variables characters have to be previously programmed from TED program to the
message.
- The message has to be activated and it has to be the last activated. When a message is not
the last one activated, it has to be activated again. The fact of activating one message which has been
previously activated does not display this message two times.
- The internal position counter of the variables has to be loaded with (0-15) value, which says
the position of the variable.
This method allows modifying a variable value or group of variables value without changing
the other variables. Every time a variable character is sent, the position counter increases
automatically to the following position. The variable direction of every character can be sent although it
is easier to load the direction value of the first variable and to let the counter increase the directions by
itself.

D0-D3= Variable position.
SV=1 Pulse activated >=10 mseg.
The variable position can be from 0 to 15 in hexadecimal (0-F), for the first line and see 4.8.1.2
“Displaying all messages in EEPROM for the other lines.
The external variables can be ASCII or Binary.
- ASCII variables: They are sent in ASCII code to the display. They take one character.
Set SR=1 (Activated)
CT1, CT2, SM=0 (Deactivated)
D0-D7= ASCII code.
D8= Irrelevant.
SV=1 Pulse activated >=10 mseg
- As BCD forms part of ASCII code, variables can be sent in BCD code with D4 and D5,
inputs. They have to be activated permanently.
Set SR=1 (Activated)

- 16 bits binary plus sign. It changes a value from 0 to FFFF (Hexadecimal) into a decimal (5
digits plus sign). It takes 6 characters. Two consecutive operations are needed to send it. The 8 high
bits with the sign must be sent and then the 8 low bits with the sign.
To send the 8 high bits:
Set SR, CT1=1 (Activated)
CT2, SM=0 (Deactivated)
D0-D7= 8 high bits.
D8= 0 (Positive sign) =1 (Negative sign)

4.8 Protocols
4.8.1 Protocol 512-M.
512-M designates the 2048 protocol for managing control messages with variables. The
messages are encoded in binary and using 11 inputs, the 2048 messages are controlled. (2E11 =
2048).
4.8.1.1 Displaying only one message.
It is the easiest way to send an only message to the display. The direction of the message
must be sent to the display inputs in binary code.
The message number must be codified to D0-D8, CT1 and CT2 inputs and keep it activated
for the period of time it is wished to be displayed. The display always shows the message whose
direction is applied.
This method neither memorise the messages nor allows codifying the variables. SM, SV
and SR control signs are not used in this method, which means that they must be activated.
Inputs:
SM, SV and SR = ‘1’ (activated)
D0-D8, CT1, CT2 = binary code
The maximum number of messages to be sent is 2048 messages by using 11 PLC outputs.
The number of PLC outputs required depends on the number of messages wished to be sent.
For example, to send 52 messages it is required to use 6 PLC outputs, which allows sending 64
messages, from the message nº 0 to message nº 63.
When the display is used to display only one message, PLC outputs can be static or relay
outputs.
4.8.1.2 Displaying all messages in EEPROM
DT-105P, DT-110P and DT-203P displays allow the entry of variables to insert in permanent
texts of the programmed messages. This value must be send externally by way of the parallel inputs
of the display.
The external variables are useful tools, which allow introducing numeric and ASCII values in
the messages or modifying them depending on the situation. For example, it can be displayed a
counter of pieces, the temperature degree, a variable of a process, etc.
A total of 16 variable characters can be associated for every line, which can be in groups or
isolated messages, and which is ordered by a position counter (see 4.7 “General specifications for
working with the variables.”)

CHAPTER 4
OPERATION
4-9
DT-203P, DT-105P and DT-110P display series
In this example, there are 8 variables in groups of (0, 1, 2), (3, 4, 5), (6, 7) from the first line.
The other 8 variables available in the line are not used. Every line has a direction of variable
associated, which must be used to send various variables to the lines.
Up to 10 messages can be displayed simultaneously in displaying messages in EEPROM
mode, which are loaded in an internal buffer of RAM memory. If there are more than ten messages, no
more messages will be accepted until some messages from the buffer are eliminated.
There are three displaying methods:
a) Displaying the first activated message.
Set CT2=1 (Activated)
CT1, SV, SR=0 (Deactivated)
D0-D8= Nº Message
SM=1 Pulse activated >=10 mseg.
b) Displaying the last activated message.
Set CT1=1 (Activated)
CT2, SV, SR=0 (Deactivated)
D0-D8= Nº Message
SM=1 Pulse activated >=10 mseg.

CHAPTER 4
OPERATION
4-10
DT-203P, DT-105P and DT-110P display series
c) Displaying all the activated messages.
Set CT1, CT2=1 (Activated)
SV, SR=0 (Deactivated)
D0-D8= Nº Message
SM=1 Pulse activated >=10 mseg.
For any of these options ( a), ( b), ( c) it is necessary to have at least one of the inputs CT1,
CT2, SV, SR, SM activated, although it is not necessary to be always the same input. In case of
deactivating all the inputs for more than 0, 5 seconds, the display will change to displaying only one
message mode (see 4.3.1) and all the messages activated will disappear.
At any time one kind of displaying mode (a), (b) or (c) can be changed to another without
deactivating the messages. It is only necessary to activate again the message with the new selected
mode. Example: If message nº3, nº22 and nº1 are activated in this order in (a) option, message nº3
will be displayed. In order to display all the messages, any of these three messages has to be
activated in (c) option.
The activation code of one message can be repeated as many times as wished without
affecting the working order of the other messages. This fact allows to change the displaying mode and
to select the message to which the variable will be sent.
- To deactivate a message.
It can be used in any of three displaying mode (A), (B), o (C).
Set SR=1 (Activated)
CT1, CT2, SV=0 (Deactivated)
D0-D8= Nº Message
SM=1 Pulse activated >=10 mseg.
- To deactivate all the messages at the same time.
Set SR, CT2 y D0 a D7=1 (Activated)
CT1, SV=0 (Deactivated)
D8= Irrelevant
SM=1 Pulse activated >=10 mseg.
When messages with variables are displayed, PLC outputs have to be static.
