Wire for the transfer of messages to the display memory.
The operating mode “Message selection by code” (See section 5.2.1) allows to save a
set of messages in the device’s internal memory (non volatile).
The transfer of messages to the equipment is done by serial line RS-232. Therefore, a
Null-modem cable must be available (Fig. 3) in order to connect the computer to the display.
The TDLWin application available on our website allows us to edit the text messages,
with icons that eases the insertion of commands for special functions such as flashing a section
of the message, displaying date, time, temperatura, etc.
This application in addition to transferring the messages to the internal memory of the
equipment, also allows saving the message in a file as backup or to transfer to more than one
display.
