Is it normal for COMM light to rapidly blink? Machine is not working. I don't know how it acted when it was working.

Thx.

The Channel 0 COMM LED flickers when it transmits, so when you're running DF1 protocol it's normal for it to flash rapidly.

I think it appears completely or almost solid green when DH485 protocol is in use, because that's constantly passing the network token.

Flashing green about 1 per second indicates it's set for DH485 but not connected to a network.

Off indicates that there's no traffic being transmitted.
