custom length cables using standard RJ45 plugs and crimping tools.
Connecting a Conference Link2 cable to the Ethernet interface could damage the
connecting device and/or the SoundStructure device.
Using the supplied 18" Conference Link2 cable, connect the left Conference
Link2 port (when viewed from the rear panel) on the SoundStructure device
to a Polycom microphone Input port on the Polycom HDX system as shown in
the following figure. If there are multiple SoundStructure devices linked
together with OBAM Link, only one SoundStructure device should be
connected to a Polycom HDX system.
A CAT5e cable that is terminated with standard T568A or T568B pin/pair
assignments will not work with Conference Link2. The Conference Link2 pinout is
different from T568A or T568B pin/pair termination.
Do not use a standard Ethernet cable to connect SoundStructure to a Polycom HDX
system.
If a longer Conference Link2 cable is required, one may be constructed using
the custom pinout (see
eight conductors, e.g., RJ45) connectors, shielded Cat5e cable or better, and
for pinout details) to enable field termination of
