Feature Operation: VIP Operation 4-23
4.22 VIP Operation
The Consolette supports 3 general purpose outputs and 3 general purpose inputs, also referred to
as VIP Outs and VIP Ins. These I/O are available on the rear of the Consolette on a 14 pin terminal
connector. An adaptor is provided with each Consolette. These I/O can function when a Control
Head is present and also when the Control Head is not present on the new Consolette.
The general purpose inputs are active low. A signal of 0.8VDC or lower will activate the input. These
signals are pulled high to 5VDC internal to the Consolette. When active, they are pulled to ground.
VIP input functionality can be assigned to a radio function and configured using APX 7500 CPS.
Functionality is programmable by the user. Popular configurations for Consolette users include:
• Emergency Alarm Receive Indicator - The Consolette can be set up via APX 7500 CPS to
activate a VIP output in the event that the Consolette receives an Emergency Alarm. Refer to
section 3.7.1.1 for details on the radio CPS programming of the Emergency Alarm Receive
Indicator.
• Auxiliary Control Indication - The Consolette can be configured such that a button press will
activate a VIP output. The buttons that can be programmed to support the Auxiliary Control
functionality are the O5 control head programmable buttons and the 3 function buttons on the
front of the Consolette. Additionally, the Auxiliary Control functionality can be assigned to the
softmenus on the auxiliary display. These softkeys can be programmed with text to help identify
what the output is used for (ex. DOOR, ALRM).
• Failsoft Indication - The Consolette can be set up via APX 7500 CPS to activate a VIP output
in the event that the Consolette enters these states: Out of Range, Wide Area, Failsoft. Each
indication can be assigned a specific VIP Output. This can be used to provide real-time
feedback to the radio dispatchers for when the trunked site exits Wide Area operation.
4.23 External Speaker
The Consolette supports connection on its rear panel to the 8-ohm mobile speaker. The mobile
speaker cable must be modified in order to connect to the 14-pin terminal connector, J103 pins 1
(E) and 2 (EXT_SPKR-).
NOTE: EXT_SPKR- and E should never be grounded. If they are grounded, this will
damage the radio.
This speaker provides receive audio and alert tones but not transmit audio. The speaker may be set
in the APX 7500 CPS to either maintain a fixed volume, or to track the O5 volume knob. Additionally,
there is an external speaker active output which indicates when the external speaker is unmuted.
EXT_SPKR_ACTIVITY* (driven low when valid audio activity is present on the secondary speaker)
is located on the DB25 Accessories Connector J104 pin 23.
The normal operation of the external speaker can be configured to be overridden by:
• connection of a Headset to the Consolette when tracking local speaker.
• activation of the MUTE_IN signal to the rear of the Consolette.
• activation of the Speaker Mute Button from the front panel when tracking local speaker.
4.24 Audio Jack
The Consolette supports a dedicated connection for use with a powered speaker or a computer
soundcard input. This output is a fixed level “line out” audio output at a nominal 300mVrms relative
to a 1.0 kHz tone at 60% FSD. This audio includes receive audio and alert tones (no transmit audio).
When there is no valid audio, this audio path is muted.
