Appendix A - LED Indicators

The Remote Cable Tester has a total of 14 LEDs, 9 horizontal indicating each individual wire inside a cable, and 5 vertical displaying a cable connection status. You can read the result from the combination of lit horizontal and vertical LEDs.

•S (Yellow) Shielding

•C/1 (Yellow) Center of coaxial cable (BNC) or wire a of TP cable (RJ45), telephone cord (RJ11) or USB

•2, 3, 4, ...8 (Yellow) Wire 2, 3, 4, ...8

•Short (Red) Short condition between wires, or between shielding and center of BNC connector.cable are detected.

•Connected or 25 Ohm (Green) A straight-through connection cable is detected. Or a standard Ethernet 10Base2 and 10Base5 terminated with 25 Ohm cable is detected.

•Non-parallel or 50 Ohm A non-straight-through connection cable is detected. Or an Ethernet 10Base2 and 10BAse5 cable with one end termination value (50 Ohm)

is detected.

•No connection/no terminator (Yellow) No cable or terminator is scanned.

•Battery good/battery low (Yellow/Green) It shows the battery status. If LED is green the battery condition is good, if the LED is yellow the battery condition is poor. Replace the old battery with a new one when the LED fails to remain lit during normal operation.
