The Wire Mapper™ C.A 7028 from Chauvin Arnoux is a professional testing device for checking and troubleshooting network cabling. It is designed for diagnosing data and voice networks as well as installed connections and is intended for communication engineers, network technicians, installers, and IT administrators. The device enables precise localization of faults in cables up to a maximum length of 150 metres and supports efficient maintenance and retrofitting of existing networks.

Applications
This device is designed for testing RJ45 cabling and is suitable for various cable types, including UTP, STP, FTP, and SSTP. It is compatible with network specifications according to TIA568 A/B, ISO, EN, USOC, and ISDN. The device is particularly used during installation, maintenance, and troubleshooting in structured cabling systems, such as in office buildings, server rooms, or when setting up telephone and data networks.

Functions and Equipment in Detail
The Wire Mapper™ C.A 7028 detects various fault types, including shorted pairs, open wires, short circuits between pairs, crossed or reversed pairs, and continuity of shielding. Fault detection is performed at both the near and far ends of the cable. Cable length measurement is displayed in metres or feet, enabling precise determination of fault location. An acoustic signal supports quick identification of the cable, especially in complex distribution fields.

Technology Explained Simply
The device features an illuminated LCD graphic display with a resolution of 128 x 64 pixels, clearly and clearly presenting results. The display allows visual inspection of cabling and shows fault codes. A warning indication for applied telephone line voltage provides additional safety during use. The identification function supports up to 9 remote modules, designated as identifiers No. 1 to 9. This enables simultaneous testing of multiple lines in a distribution field.

Compatibility and Accessories
The device is designed for RJ45 connectors and supports the mentioned cable types. Suitable accessories include a set of 2 test leads RJ45 for the CA 7028, used to connect the device to the cable system under test. Cable types UTP, STP, FTP, and SSTP are fully covered, making the device suitable for a wide range of network applications.

Installation and Mounting
Installation is performed by directly connecting the device to the cable under test via the RJ45 plug. The remote module is connected at the other end of the cable, enabling testing over the entire cable length. Operation is performed using the buttons on the device, which activate the various test functions. Results are displayed on the screen, with fault types and cable length immediately visible.

Advantages in Operation
The combination of fault detection, length measurement, and identification function enables fast and precise diagnosis of cabling faults. The use of up to 9 identifiers simplifies testing of distribution fields with multiple lines. The voltage warning function increases safety during work. The compact design with dimensions 165 x 90 x 37 mm and weight 350 g (transmitter) and 40 g (remote unit) ensures ergonomic handling and mobile use. The display with backlighting ensures good readability even in poorly lit environments.
