Cable Tester

The WireMap 620 is a cable tester that offers one-button operation and was created to simplify the work of installers, technicians and administrators who support 10/100 Mbit ethernet LANs. In addition to testing LAN cables for correct continuity, the device will display link and traffic information and can act as a toner for cable identification. It supports link & traffic testing for 10BASE-T and 100BASE-TX networks and will test continuity of any UTP or STP cable using RJ-45 connectors. It was designed primarily for ethernet systems using CAT5, CAT5e and CAT6 cables but can also be used to check telco and Token Ring cables.

All of the device's functions are automatic. The device will try to establish link with any ethernet hub or switch. It supports 10 Mbit, 100 Mbit and auto-negotiation. If a link partner is detected, the tester will display information about the speed and duplex status of the link and will then display the relative traffic load in the form of a bar graph. If you connect to a switch port, you will usually see only broadcast traffic since the network would not be addressing any data to the tester itself. If no link partner is detected, the device will attempt to perform a wiremap test.
