Hi,
The voltage across the following pins is <5V and I’m no longer able to speak to slaves when connected to my AB7072. Is the unit damaged?
Kind Regards,
Christopher

Hello,
What is the voltage on the line right now?

Hi Kevin,
It’s 4.25V currently
The low of a drop should not affect the device communication.
What is the current LED status of the unit?
I should add the slave device and cable are both working, and I can speak to the AB7072 over Ethernet.
All that remains is the Serial port…
Kevin,
The subnet is red but the others are healthy.
If I have inadvertently damaged the serial transceivers during wiring, how could I tell?
If everything is configured correctly, and no communication is occurring, then it could be a damaged module.
I would create ticket to proceed with a possible RMA.
