ports labeled “tranceivers.” The ferrite should be fitted at
the basestation end of the CAT-5 cable. Position the ferrite
as close to the basestation as possible. A suitable ferrite is
available from Wurth Elektronix. The part number is 742 711
32.
Note: It is recommended that shielded CAT-5 cable is used for
FreeSpeak systems.
CONNECTING TO PARTY-LINE INTERCOM
SYSTEMS
Up to two channels of party-line intercom can be connected to the
FreeSpeak basestation. The descriptions below will discuss
connections with Clear-Com and compatible party-line, RTS party-line,
the ability of FreeSpeak to power up to four Clear-Com beltpacks by
itself, and the front-panel settings associated with these party-line
connections.
Using the front-panel display and rotary encoder, the user may go into
the PORTS menu, select the desired party-line channel, and create a
five-character alphanumeric label for it. This is the label that would
then appear on any FreeSpeak wireless beltpacks to which that
party-line connection was assigned for communications. In the
GROUPS menu, the party-line connection can be assigned as a
member of any of the groups, as desired.
CLEAR-COM AND COMPATIBLE PARTY-LINE
Clear-Com and Clear-Com-compatible wired party-line intercoms
connect to the PL CH-A and PL CH-B connectors in a similar manner
to connecting beltpacks or remote stations to the intercom line.
Typically that wired intercom connection would have a 30-VDC current
on Pin 2, coming from a main station or an intercom power supply. The
second connector in the pair may be used as a loop-through to go to
other wired party-line stations or beltpacks, or to a second FreeSpeak
basestation. The pinout for party line connector is shown in table
Table 4-1.
