as close to the Base station as possible. A suitable ferrite is available from
Wurth, part number 742 711 32.
4.2 Connecting to partyline intercom systems
Up to two channels of partyline intercom can be connected to the FS II Base station. The
descriptions below will discuss connections with Clear-Com and compatible partyline, RTS
partyline, the ability of FS II to power up to four Clear-Com partyline beltpacks by itself, and
the front-panel settings associated with these partyline connections.
Using the front-panel display and rotary encoder, the user may go into the PORTS menu,
select the desired partyline channel, and create a five-character alphanumeric label for it. This
is the label that would then appear on any beltpacks to which that partyline connection was
assigned for communications. In the GROUPS menu, the partyline connection can be
assigned as a member of any of the groups, as desired.
4.2.1 Clear-Com and compatible partyline
Clear-Com and Clear-Com-compatible wired partyline 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 partyline stations or beltpacks, or to a
second FS II Base station. The pinout for partyline connector is shown in Table 4-1.

4.2.1.1 To connect partyline equipment to the Base station
1) Check that the partyline LED on the front-panel is out, which indicates that the
partyline connection is disabled from the Base station.
2) Connect, and if appropriate, power up, the external partyline equipment.
3) Enable the partyline by pressing the “enable” button on the Base station’s front panel.
The Base station detects power and termination settings when the partyline is enabled by
pressing the “enable” button on the Base station’s front panel, or when the Base station is
powered up after having enabled the partyline. The Base station remembers that the partyline
is enabled when it powers up.
