You need a serial printer that has RS232 interface. Most serial printers operate at 8 data bit 1 stop bit no parity. So you need to change the PLC's comm port #1 to the same by running the command:
SETBAUD 1,3
during the 1st.Scan initialization routine. If your serial printer has different settings then you need to change the SETBAUD parameters to match that of the serial printer.
You also need to make sure that you use the right cable. If the serial printer is designed to work with a PC with straight cable, then you will need a male-to-male null modem in order to connect to the printer.
Note that once you have changed the baud rate you will need to change that in the TLServer in order to talk to the PLC via COMM1. But we recommend using COMM3 (RS485) together with an Auto485 adapter to do programming and therefore dedicate COMM1
to serial printer only.
You can check the SETBAUD table in your T100MD+ user's manual page 1-16 and 1-17. A copy of the user's manual can be downloaded from the following webpage:
http://www.tri-plc.com/downloadmd.htmTo set the baud rate back to factory default, use
SETBAUD 1,6,
or simply turn off power to the PLC and turn it back ON. The SETBAUD is volatile so power reset will take it off (of course if you have the SETBAUD 1,3 statement in 1st.Scan custom
function then that won't help because the 1st.Scan will initialize it and turn it to 9600 bps.) so you need a function that will reset the baud rate back to default 38400 bps.
