5. Select the LPM COM port from the Test Enable/Disable drop-down box.
6. Click the Perform Test(s) button.
Result: The test result displays.
7. If the test passes, the LPM COM port is functional.
8. If the test fails, ensure the correct loop-back connector was used, then, replace the CTM and repeat steps
4 and 6.
9. If the test fails again, replace the LPM.
Testing the Synchronization Circuit
This first part of this test checks the functionality of one Reader’s SPM. The second part of this test
checks the Synchronization wiring from one Reader’s SPM to the synchronization circuit terminal block
Prerequisites:
 At least one RF module installed in the Reader
 Both Primary and Secondary CTMs are configured the same
 Synchronization enabled
Testing the SPM and CTM
1. Disconnect the Synchronization circuit wiring from the SPM terminal block
2. Using two short jumper wires connect Tx+ to Rx+ and Tx- to Rx- on the SPM terminal block, leaving the GND
terminals unconnected (see SPM terminal block connections, page 267).
3. If the SYNC LED on both CTM’s illuminates solid green, the SPM and CTM’s are functioning properly.
4. Reconnect the synchronization circuit to the SPM terminal block.
