is no PTT line associated with this jack, so the transmitter must still be keyed using the control
unit PTT switch.
Programming Jack - A standard eight-pin jack for connecting the computer and RPI to program
the transceiver.
NOTE: The junction box is required to program the transceiver when this control unit is used.
2.10.2 INSTALLATION INSTRUCTIONS
Optional Junction Box Used (Figure 2-10)
1. Install the transceiver as described in Sections 2.2 to 2.5. Connect the microphone hanger
to chassis ground as described.
2.
Mount the junction box in a convenient location near the control unit using the included
mounting bracket and hardware.
3.
Route the 17-foot (5-meter) control cable from the transceiver to the junction box as
shown in Figure 2-10. Connect it between the remote pigtail of the transceiver and the male DB9
jack of the junction box.
4.
The two wires coming from the connector on the transceiver end of the control cable
route speaker audio to the junction box. Insert the pins on these wires into the Pins 1 and 2 slots
of the accessory cable connector.
NOTE: The accessory and siren pigtail cables have the similar connectors. Be sure to connect to
the black accessory connector, not the yellow/orange siren connector.
If a jumper has been connected between Pins 1 and 3 on the accessory connector, remove it. A
speaker can also be connected directly to Pins 1 and 2 if desired. Refer to Section 2.7.2 for more
information.
5.
Plug the 4.0-
Ω
external speaker into the SPKR OUT jack of the junction box. Plug the
control unit into the male DB9 connector of the junction box.
6.
If applicable, connect the tape recorder or other device to the LINE OUT jack.
7. Connect the earphone or earphone/microphone to the EARPHONE/MIC jack (the
external speaker automatically mutes when an earphone is connected to this jack). The earphone
output is the “tip” of the jack and the microphone input is the “ring” (ground is the “sleeve”).
Junction Box Not Used (Figure 2-11)
The Handheld Control Unit can be plugged directly into the remote pigtail of the transceiver
in applications where the transceiver and control unit are located near each other.
In other applications where the transceiver is mounted remotely, optional 17-foot Control
Cable, Part No. 597-2002-267, is required to connect the control unit to the transceiver.
Proceed as follows:
1. Install the transceiver as described in Sections 2.2 to 2.5. Connect the microphone hanger
to chassis ground as described.
2.
Route the 17-foot (5-meter) control cable from the remote pigtail of the transceiver to the
control unit as shown in Figure 2-11. Secure the connectors using the captive screws.
