Operating modes
The LAN/USB cable tester was developed to
read out the correct cable layout configura
-
tion. These cables include USB (A/A), USB (A/
B), BNC 10Base-T, 100Base-TX, 1000Base-
TX, token ring, AT&T 28A, coaxial, EIA/TIA
68A/68B and RJ11/RJ12 modular cables. The
cables can be connected if you wish to test BNC,
coaxial, and RCA modular cables. If you need to
test remotely-installed cables, either on a panel
or wall plate, you can use the remote terminator.
The LAN/USB cable tester can also test RJ11/
RJ12 cable. Please use the correct adapter and
follow the instructions below.
