Installing the IC-4FXS interface card cables
The IC-4FXS supports up to four analog connections (see
table 34
for port pin-out listing) via cables termi-
nated with RJ-12 plugs (see
figure 72
on page 106).
Note
The IC-4FXS is actually equipped with RJ-11 sockets. An RJ-11
socket is similar to an RJ-12 socket but pins 1 and 6 are omitted.
Note
Pins not listed are not used.
