Category 5 cable tester
Jensen's LanRover tests for opens, shorts, reversals, miss-wires, and split pairs. When a connection from the main unit to the remote is sensed, testing begins automatically. The LED for each pair will indicate "on" for a good pair, "off" for an open pair, or flashing for a bad pair. Indicators appear on both the main unit and the remote. A press of the button will induce a tone on all pairs, and subsequent presses will cause a tone on one pair, advancing to the next pair in turn.

New Product CORRECTION
In the New Products section of our May 2001 issue of Cabling Installation & Maintenance, we announced a connectivity tester (p. 131) as a product by Jensen Tools instead of Fluke Networks. Here is how the section should have appeared:
The NetTool connectivity tester by Fluke Networks identifies a jack as Ethernet, phone, token ring, or inactive, and checks link pulse for speed, polarity, duplex, level information, and receive-pair. It resolves PC network configuration issues such as Internet protocol (IP) address, default getaway, and e-mail and Web servers, while showing key network resources used by that PC such as servers, routers, and printers. In addition, the tester simultaneously monitors network health for full-duplex connections, with individual counts for both the desktop and the network conversations. A Problem Log lists problems detected on the PC and network such as addressing issues, e-mail, and Web problems.
