6� COR/audio unmute: Input designed to monitor the receive status
of the host mobile radio. Ideally, it is driven by an “audio unmute”
switched ground command in the host mobile. i.e. when the radio’s
speaker unmutes to pass audio then the COR input should toggle in sync.
Alternatively, it could be driven by the radio’s unsquelch command that
factors in reception of required correct CTCSS tones, etc. Where COR is
not available the X10DR’s voice audio detect capability will in almost
every case allows satisfactory operation with minimal voice clipping.
7� Ext� PTT output: Switched ground output designed to drive the host
mobile radio PTT.
8� Talkaround audio bus: passes fixed audio level between multiple X10DR
gateways connected to XJB/XJB-DCI (Junction Box). The line is also used
for Remote PTT input*.
9�Shield� DC /Digital ground connection.
* Remote PTT: This provides an alternative remote PTT to transmit secure
microphone audio via the host mobile radio. You may choose to connect
to a motorbike handle bar PTT, a hidden palm or footswitch, a wireless PTT
device, or even to an output from the host mobile equipped to provide
remote radio monitoring of the secure microphones users audio. In such
remote monitoring cases, use of the remote PTT input causes the sensitivity
of the INTERNAL secure microphone to be greatly increased, so a control
room operator can more easily monitor the health or safety of the user.
There is no increased audio gain when a headset is connected to the
audio port at the base of the secure microphone.
