The Identifier No. 1 is a replacement part for the Chauvin Arnoux C.A 7028 LAN Tester, specifically developed to support diagnosis and verification of LAN connections. It serves as a remote module at the other end of the cable under test and enables identification of wiring faults as well as visual confirmation of the test status by the second operator. The device is designed for use in professional network environments where precise and reliable fault detection is required.

Applications

The identifier is used in conjunction with the C.A 7028 Wire Mapper™ to test network cables in data and voice networks. It is particularly useful for testing installed connections, installing new lines, or maintaining existing networks. The application is intended for environments where multi-pair copper conductors with RJ45 connectors are used, complying with standards TIA568A/B, USOC, or ISDN. The identifiers allow up to nine lines to be tested sequentially from a distribution panel, with each identifier carrying a unique number (1 to 9) to facilitate identification.

Functions and Equipment in Detail

The Identifier No. 1 is equipped with an RJ45 connector and is compatible with cable types UTP, STP, FTP, and SSTP. It supports detection of various wiring faults, including shorted pairs, open wires, short circuits between pairs, crossed or reversed pairs, and continuity of shielding. These faults are displayed graphically on the main device’s screen, with the exact fault position indicated in metres. This function enables quick localization of faults, especially in already installed cables, and reduces troubleshooting time.

Technology Explained Simply

The identifier works in conjunction with the C.A 7028 Wire Mapper™, which features EDT™ technology (End Discrimination Technology). This technology detects the cable termination and displays the wiring diagram graphically, making the type of fault and its location clearly identifiable. The device also detects whether active data or telephone traffic (e.g. 10 Mb/s, 100 Mb/s, Token Ring) is present on the line under test, to avoid accidental testing on active LANs. The battery status is displayed upon power-up, enabling planning of test duration, and the device enters standby mode after three minutes of inactivity to conserve battery life.

Compatibility and Accessories

The Identifier No. 1 is exclusively intended for use with the C.A 7028 LAN Tester. It is part of a series of remote modules available with numbers 1 to 9 to identify multiple lines simultaneously. Compatible accessories include a set of two RJ45 test leads, specifically developed for the C.A 7028, enabling the connection between the main unit and the identifier.

Mounting and Installation

Installation is performed by simply plugging the identifier into the RJ45 connector at the end of the cable under test. No additional tools or mounting procedures are required. The connection is established via electrical signal transmission between the main unit and the remote module, allowing testing without any physical modification to the wiring.

Operational Advantages

The Identifier No. 1 features a robust and durable design suitable for regular use in technical environments. Its compact size (165 x 90 x 37 mm) and low weight of 350 g facilitate transport and handling. Simple operation and graphical fault display ensure fast and precise network analysis, saving time and resources in operation. The IP54 protection rating ensures resistance to dust and water, enabling use even in slightly exposed environments.
