Testing the CTM Ethernet 1 port
This test verifies that a CTM Ethernet 1 port is working properly.
Prerequisites: A service laptop.
1. Connect a service laptop directly to CTM Ethernet 1 port being tested (see Connecting a service laptop to
the Reader, page 40).
Ensure that you can access the CTM web interface with the service laptop (see Accessing the CTM
web interface, page 41). This confirms the Ethernet port is functional.
Testing an LPM COM port
This test verifies that an LPM port is working properly and requires a simple loop-back connector.
Prerequisites: Connect the service laptop to the Reader configuration port to access the CTM web
interface. Refer to Connecting a service laptop to the Reader, page 40. You must have Advanced User
permissions.
Note: All OBU transactions on this port are buffered while the LC is disconnected from the LPM ports to
perform the test.
1. Disconnect the serial cable from the LPM COM port being tested.
Note: The LPM is either RS-232 or RS-422. The loop-back test will only work if the appropriate loop-back
connector is used.
