Decode Functions:
Query:
When the speaker mic receives a Query command from the CAD-800 it will transpond back indicating if it
is currently enabled or disabled.
Polling:
When the speaker mic receives a Polling command from the CAD-800 it will transpond back to the CAD
with the unit’s last location fix.
Selective Call:
The unit is capable of receiving three types of selective calls; individual, group and all. The
individual call is based on the group ID and unit ID. The group call is based on only the group ID. The all call is for
all units within the system. The unit will transpond back to the CAD-800 only on the individual call. The ring tones
consist of 50 msec of 627 Hz & 1320 Hz dual tone alternating with 50 msec of 627 Hz 1670 Hz dual tone. The
individual call ring consists of one long warble tone that lasts 1.6 seconds with a 4 second gap between rings. The
group call ring consists of a double warble tone (600 msec on, 400 msec off, 600 msec on) with a 4 second gap
between rings. The all call ring consists of a triple warble tone (400 msec on, 200 msec off, 400 msec on, 200
msec off, 400 msec on) with a 4 second gap between rings.
Radio Disable & Radio Enable:
If a radio becomes lost or stolen or the user does not pay for access, the
speaker microphone can be “disabled”, so it will no longer key the radio or pass receive audio from the radio.
When disabled it will still respect Query, Polling and Spy commands. If the radio is found it can then be
Spy (Remote Monitoring):
When the Spy command is received by the unit it will PTT the radio and pass audio
from the microphone to the radio for transmission. The length of time of this transmission is programmable for 15
seconds, 30 seconds, 45 seconds or 60 seconds.
Emergency Acknowledge:
If the unit is programmed to send the Emergency ANI continuously or for multiple
times, the receipt of the Emergency Acknowledge command from the CAD-800 will cause the unit to stop the
emergency sequence and no longer send Emergency ANIs.
