The WireMap 620 was created to greatly simplify the work of installers, technicians and administrators who support 10/100 Mbit ethernet LANs. The 620 is affordable, easy-to-use and its unique set of features makes it a valuable addition to everyone’s tool kit. In addition to testing your LAN cables for correct termination, the 620 will display link and traffic information and can act as a toner for cable identification. The 620 supports link & traffic testing for 10BASE-T and 100BASE-TX networks and will test continuity of any UTP, STP, or FTP 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 WireMap’s functions are automatic. Simply press the ON/OFF button on the front panel to activate the 620 and begin testing. If you see a LOW BATTERY message at any time, then simply replace the 9-volt alkaline battery in the rear of the main unit. LINK & TRAFFIC checks are performed continuously. The WireMap will try to establish link with any ethernet hub or switch. The 620 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.
