Testing the LC Ethernet port

This test verifies that a LC Ethernet port is working properly.

Prerequisites: A service laptop.

1. Connect a service laptop directly to LC Ethernet port (see Connecting a service laptop to the Reader, page

34).

Note: Ensure that you can access the web interface with the service laptop (see Accessing the

Web interface, page 35). This confirms the Ethernet port is functional.

Testing the Synchronization Circuit

This first part of this test checks the functionality of the Reader’s Sync Port.

Testing the Sync circuit

1. Disconnect the Synchronization circuit wiring from the Sync port

2. Using two short jumper wires connect Tx+ to Rx+ and Tx- to Rx- on the Sync port, leaving the GND

terminals unconnected (see Sync Port connections, page 140).

3. If the SYNC LED illuminates solid green, the Sync circuit is functioning properly.

4. Reconnect the synchronization circuit to the Sync port.
