Hi all!
I'm using a 5069-SERIAL card for the first time, though I have plenty of experience with serial on other AB platforms. I'm running into difficulties and wondering if anybody might have an idea of the dumb thing I'm missing.
This is an upgrade from a SLC5/04 with a 1746-BASIC module to a 5069-L320ER with a 5069-SERIAL card. I'm trying to use the card to read data from an existing barcode scanner and weigh scale, and not having any luck. I can receive data from both devices on my computer using a USB/serial adapter and the Hercules testing application. But I can't receive data in the PLC. I've tried sending data to the PLC from my computer, and the RX light flashes. I've also tried sending data to my computer from the PLC, and the TX light flashes. So I think I have the wiring correct. I'm guessing I'm doing something wrong in the setttings, but I've double-checked all the standard things like baud, stop bit, etc.
Any ideas? Thanks!
