When a good test is done the “pass” icon will appear. Should a miswire occur between local and remote units, the LCD will show which pin the fault is on, along with a “fail” icon. After completing a telephone or network test, the SOHO Tester displays the wiremap and any faults associated on its easy-to-read LCD.

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.
