This accessory set from Chauvin Arnoux, consisting of identifiers numbered 2 to 5, is specifically designed for use with the C.A 7028 LAN tester. It enables precise identification and diagnosis of multiple LAN connections within a network, allowing technicians to efficiently assign individual cables to specific endpoints or distribution panels. The identifiers allow simultaneous testing of multiple lines, with each identifier carrying a unique number displayed on the main device. This is particularly useful during maintenance or installation of networks in larger facilities, where multiple cables are connected to a distribution panel.

Applications
This accessory set is intended for professional users in the field of network infrastructure, including communication technicians, cabling installers, and IT administrators. It is used to locate faults in data and voice networks, especially in installed cabling that complies with TIA568A/B, USOC, or ISDN standards. The identifiers support network diagnostics, particularly when testing cables that terminate in distribution panels or in hard-to-reach locations.

Functions and Equipment in Detail
The identifiers are equipped with an RJ45 plug, which is connected to the end of the cable being tested. They work in conjunction with the C.A 7028 Wire Mapper™, which features a graphical LCD display to detect faults such as shorted pairs, open wires, crossed or reversed pairs, and shield continuity. The identifiers are active and signal at the other end of the cable whether a test is complete and whether a fault exists. The set includes numbers 2, 3, 4, and 5, enabling up to nine different lines to be identified using remote modules numbered 1 to 9.

Technology Explained Simply
The identifiers use End-Discrimination Technology (EDT™), which allows the cable termination to be uniquely identified. This makes fault localization more precise, as the device not only detects the fault but also indicates its position along the cable. The battery status display upon power-up helps estimate the remaining operating time. The device automatically enters standby mode after three minutes of inactivity to conserve battery power. The identifiers are robust and designed for professional use, with an ABS plastic housing that is protected against water and dust (protection rating IP54).

Compatibility and Accessories
The set is compatible exclusively with the C.A 7028 LAN tester. It can be supplemented with additional identifiers covering numbers 1 to 9, enabling up to nine lines to be identified simultaneously. Compatible accessories include a set of two RJ45 test leads for the CA 7028, which can be used to connect the tester to the network.

Installation and Mounting
The identifiers are simply connected to the free end of the cable being tested. The RJ45 plugs allow for quick and secure connections. Testing is performed via the main device, which displays the identification number of the connected identifier. Operation is carried out via the display of the C.A 7028, which graphically shows the type and location of faults.

Operational Advantages
Using the identifier set enables fast and precise network analysis, especially when testing multiple cables in a distribution panel. The unique numbering of the identifiers prevents confusion and accelerates fault localization. The robust construction and IP54 protection rating make the set suitable for use outdoors or in harsh environments. Combined with the C.A 7028 Wire Mapper™, it offers a comprehensive range of functions for professional network services.
