The CALL DESTINATION screen appears.
4. Select the port or group to be connected to the party line by scrolling
to it and pressing the rotary encoder. Doing so creates a route to the
selected destination—this port or group can now hear the activity on
the party line. (Note: this option can also be set to NONE.)
5. Select TYPE from the menu.
6. Select either Clear-Com, Drake, or RTS.
The basestation automatically sets the termination, audio levels,
and call signaling options for the selected party-line system.
Note that the Basestation does not detect the RTS call signal.
7. If the changes are saved the route will be reinstated on power up.
Note: Suggested settings for a party line connection are that the
VOX should be set to -26dB, the gain output to -6dB and the
input to 0dB.
CONNECTING TO AN RTS™ WIRED BELTPACK
CellCom can only transmit and receive audio from channel 2 of an
RTS wired beltpack. Connect using a standard XLR cable. Ensure that
the party-line type is set to “RTS” using the menu on the basestation
before enabling the party line. See the chapter “Programming a
System from the Basestation” for more information.
Warning: Previous versions of this manual described a cable
which would allow access to channel 1 of a dual channel
RTS beltpack. DO NOT attempt to use a cable like this as
it could result in damage to the CellCom basestation.
FRONT-PANEL ADJUSTMENTS FOR PARTY-LINE
CONNECTIONS
To connect the party-line channels to CellCom and make the
communication available to the rest of the system, press the CH-A
and/or CH-B enable switches. The LED will light, and the connection is
made. To disconnect the party-line connections, press these switches
again. The switch may be “locked” in the SYSTEM menu so that the
party lines may not be disconnected.
Because party-line intercom does not have global level control on a
channel, input and output level controls are provided via the front panel
programming. Scroll to PORTS on the main display screen and press
the rotary encoder to select. Scroll to PLCHA or PLCHB and press to
select. Select LEVELS, then select the input or output level. (This
notation is relative to the basestation–input level refers to the level at
which everyone else hears the party line, and output level refers to the
level at which the users on the party line channel hear everyone else.)
Use the rotary encoder to adjust the numerical level—clockwise to
increase the level and counter-clockwise to decrease the level.
