OPERATION
4-1
DT-203X, DT-105X and DT-110X display series
4. OPERATION
4.1. Initial reset.
The series DT105/110/203/X displays are industrial displays controlled by serial line
RS-232 or RS-485, from 1 to 8 rows and 1 or 2 display sides.
Before connecting the display to the power supply, it must be checked that all
connections have been set properly and that the display has been firmly fixed. Every time the
display is connected to the power supply, there is an initial reset, which check all the points of
the display
Following the reset, the display reads the message memory and initialises the
messages table. The world «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 depending on the protocol.
 TDL protocol: All programmed messages are shown.
 ModBus protocol: Message 0 is shown.
 Omron protocol: Message 0 is shown.
 ASCII protocol: Message 0 is shown.
 S7-200 protocol: Message 0 is shown.
4.2. Message programming
In order to program the messages in the memory Eeprom, a PC and the TDL software
are necessary. TDL is software specifically designed to program the messages into the display.
See the TDL Manual to know how the TDL works.
To program the messages, the display must be configured with the following
parameters: (See 4.3 “Set parameters.”).
Display Address = 000
Protocol = TDL
BaudRate = 9600
Data length = 8
Parity = Par
Serial input = Depends on serial line (RS-232 or RS-485).
The program time could take some minutes.
4.3. Set parameters.
Before using the display you must set the parameters.
To set the parameters, the display has a pair of pushbuttons located at the bottom of
the case. The menu is in four languages. Protocols Omron and S7-200 contain more
parameters.
