First time Install of Contact Closure Relay - 8-Channel MirC

First time instillation, I’m able to detect both the input and output boards when connected to my laptop and switch. I configured the devices based on the https://relaypros.com/photos/pdf/Gen3_Ethernet_MirC-X_Quick_Start_Guide.pdf

The input board is not detecting any contact closure. After both boards are configured, I am only able to find the “server” device on the NCD ConfigTool.

When running a command prompt to ping both IPs, the client IP drops connection every 4th attempt.

Trying to get this set up locally on a unmanaged 5 port switch before integrating into the customers network

Looking for overall assistance in this instillation.
