The AEMC Wire Mapper Pro CA7028 is a handheld structured cable mapping and troubleshooting tester designed for use on UTP, STP, FTP and SSTP cabling equipped with RJ-45 connectors and wired to either TIA 568A/B (ISO 11801 and EN 50137), USOC, or ISDN specifications. The CA7028 detects open circuit pairs, shorts, crossed wires, crossed pairs, reversed pairs, split pairs, and shield faults.

In the event of opens and shorts, the CA7028 uses TDR technology to indicate if the fault is at the near end or the remote end of the cable or if it is somewhere in between. It will then indicate the distance to the fault.

The AEMC Wire Mapper Pro CA7028 LAN & Cable Tester has the ability to measure and indicate the length of the cable under test using a Vp (Velocity of Propagation) set by the user either manually or from a built-in library. It will measure and report the length of all four pairs of wires in the cable under test. It also generates an audible tone that is transmitted into all four pairs on the cable under test. This can be used for cable tracing and identification in conjunction with a tone receiver.

The AEMC Wire Mapper CA7028 Cable Tester also has the ability to identify telephone and data lines. If the main unit is plugged into an operational RJ-45 socket it will give a continuous warning tone and display if a telephone voltage is present on any of the pins. If the Service Detect key is pressed it will check and display telephone, 10BaseT, 100Mbit+, and token ring active service.
