Installation Guidelines

Install the terminator on the final device connected to the CEX bus segment. Ensure the DB25P connector is properly aligned and secured using the screw fixing mechanism.

Route communication wiring separately from power cables to minimize electromagnetic interference. Verify that only the last unit on the CEX bus uses the termination device to maintain correct bus operation.

Inspect connector engagement and fastening before system startup.
