Hi,
I'm trying to send hex strings to a printer via the serial port of my micrologix 1500 but it is not working. I'm not getting any activity on the port when hooked up to the printer, but I am able to see the activity on that same port when I hook up my laptop in hyper terminal to it. In Hyper terminal I see the strings being sent, from the PLC, exactly like I want them to, but it seems like there is missing something when it comes to connecting to another device. I'm using a standard crossover cable when I hook up to my PC but the printer only allows me to hook up Rx, Tx, and GND, do I need all of the other standard serial connector pins hooked up on the PLC for this to work?
Thankyou
