Error 28995-4

Hi. Maybe you have damaged cable to the Teach Pendant.

Many different reasons may be at the root of this issue:
- damaged TP cable, it would require cable replacement.
- damaged TP pins on connector, in many instances it is recoverable.
- bad Ethernet on TP, it would require TP replacement.
- bad Ethernet on robot CPU (either APC820/830/2100), it would require CPU replacement.
- bad or corrupt CompactFlash installed in robot CPU, either you can reflash it or it would need to be replaced.

Usually to understand how severe the issue is, we try to connect with WinC5G, if the CPU is alive you will connect.
