2. Connect, and if appropriate, power up, the external party-line
equipment.
3. Enable the party line by pressing the “enable” button on the
basestation’s front panel.
The basestation detects power and termination settings when the party
line is enabled by pressing the “enable” button on the basestation’s
front panel, or when the basestation is powered up after having
enabled the party line. The basestation remembers that the party line
is enabled when it powers up.
When the CellCom basestation detects a wired party line being
connected with 30 VDC on Pin 2, it does not enable the 24-VDC power
supply that the CellCom basestation supplies to the connector to
support a handful of locally connected wired party-line beltpacks. The
basestation then appears to the wired party-line system as a remote
station.
The first call to a Party Line channel A or B results in the call alert and
subsequent ones do not give any further alerting unless the Party Line
channel buttons on the basestation are toggled. This prevents all calls
giving alerts when this is not necessary.
CONNECTING DIRECTLY TO CLEAR-COM
PARTY-LINE BELTPACKS
PL CH-A and PL CH-B have the ability to directly support up to four
Clear-Com RS-501 or RS-601 party-line beltpacks each, without any
other connection to a wired party-line system. This feature gives the
convenience of being able to add a few wired beltpacks when needed
to a CellCom installation.
Connect a standard two-conductor shielded microphone cable to the
PL CH-A connector, and then connect it to a Clear-Com single-channel
party-line beltpack. Enable the party line and the basestation will
enable the required 200-ohm termination, and will supply 24-VDC to
Pin 2 to power the beltpack(s).
It is possible to daisy-chain up to four beltpacks, or use an intercom
XLR splitter at the basestation to feed mic cables connected to the
individual beltpacks. Because it is a 24-volt rather than a 30-volt
current, the maximum length of cable that can be connected (the sum
of all of the runs) will be shorter than what is expected with the
standard party-line voltage. Do the same with PL CH-B to support an
additional four beltpacks.

1. From the main menu, scroll to PORTS and select by pressing the
setup/enter knob in.
