Operation
To operate the Model 240 Remote Network Cable Analyzer, follow these steps:
1. Slide the switch on the right side of the tester to the CABLE position.
2. Connect one end of the cable to be tested into the RJ45 jack on the master unit and the other end into the RJ45 jack on the remote terminator. The remote terminator can be locked into the master unit for testing patch cables.
3. Press and release the test button. Check the horizontally aligned green LED indicators (1-2, 3-6, 4-5, 7-8, SHIELD) for integrity status: a solid light indicates the pair is OK, a flashing light indicates a fault, and no light indicates an open pair.
4. Check the vertically aligned LED indicators (SHORT, REVERSED, MISWIRE, SPLIT PAIRS) for wiring faults.
5. For detailed fault information, hold the TEST button for 2 seconds to activate “Debug mode,” which tests each pair individually and displays the fault status.
6. Turn the power off after testing to prevent battery drain.
For tone generator operation:
1. Slide the switch to the TONE position.
2. Connect the cable to the RJ45 jack on the master unit. To send a tone into a patch panel, use a patch cord to connect the tester to the patch panel.
3. To generate a tone, press and quickly release the TEST button for a single tone, or press and hold for two seconds for a dual tone.
4. Use a cable tracer to trace the cable, as the signal will be strongest near it.
5. Turn the power off to stop the tone and prevent battery drain.

Safety & Warnings
– Do not connect the 240 to a live circuit as this may damage the tester.
– Testing in a high frequency activated area may cause the tester to give inaccurate readings.
– Do not drop or get the tester wet as it may cause internal damage.
– Do not place the tester in areas of high humidity or direct sunlight.
– Do not open the tester or attempt to repair in case of malfunction.
