Hi there,
Trying to get some ascii serial communications working via RS485 (COMMREQ functions).
I have attached our wiring for the COM2 (SUBD15) port.
Does this look correct?
When hooking up a RS485 usb converter to the port to view outgoing PLC commands, our PLC's send commands contain the correct number of bytes, but bytes are all rendering incorrectly.
Any common COMREQ settings or tricks that are often overlooked would be greatly appreciated.
