Original system was PV300 and ML1000. Comms is via 1761-NET-AIC. That setup has been working for 10 years or so.
Connecting laptop via standard RS232 port connects to ML1000, but kills comms to PV300. That was the only issue.
We needed another output. Upgraded to a ML1200. Copied program from ML1000, changed processor setting, and downloaded to the ML1200. Then added extra rung for new output. The ML1200 won't talk to the PV300. Lights are flashing, but PV300 says "error 612 - no nodes...". Reconnect ML1000 and it works.
RSLinx Autoconfigure shows the ML1000 at 9600, the ML1200 at 19,200.
PV300 shows 19,200. PLC name is "Micro". PV300 is set for "Micro".
DCOMM light is off. I can't see how to change ML1200 comms in RS500. It's DF1.
This should have been easy. I've been trying different settings for hours. What am I doing wrong?

RS500 Don't remember, but same vintage as above.
