SOHO Tester

All you need to test your small office or home wiring systems.


Please call 877-877-2269 for a replacement product or part.

Product Features

  • Handheld unit reliably tests 8-wire network cables, 6-wire telephone lines, coax cables, and more.
  • Get clear pass/fail results on the large seven-segment LCD.
  • Built-in tone generator for use with tone tracers.
  • Test results are displayed in wire-map format.


Test for shorts, opens, miswires, reversals, and split pairs in any of its three test modes (telephone, coax, and network).

Here's the all-in-one tester for servicing home and small offices with a mix of copper and coax cabling. Designed exclusively for low-voltage types of cable commonly used for home networking and home automation, the SOHO Tester identifies and verifies cable TV, telephone, audio, and 8-wire network cabling at the touch of a button.

Upon completion of a telephone or network test, the SOHO Tester displays the wiremap and any faults associated with the various cable types on its easy-to-read LCD.

If there's a miswire detected between local and remote units, the LCD shows which pin the fault is on, along with a "fail" icon. When the "pass" icon appears, you know it's a good test.

The tester also has a Tone mode that generates audio tones for use with tone traces on all pairs, a selected pair, or a selected pin.

The SOHO Tester is comprised of a main local unit with a shielded RJ-45 connector and coax F and RJ-12 connectors plus a remote unit with a shielded RJ-45 connector and an RJ-12 connector. For convenient transport, the remote unit attaches to the bottom of the main unit.

You can also order extra Coax Remote Identifiers as well as RJ-45 or RJ-11 Wire Mappers for identifying and mapping multiple points of termination (see "Related Products").

The tester's Auto-Off feature keeps power consumption low and preserves battery life by shutting down the unit automatically during periods of inactivity.
