460 Scrambler Settings Screen
Settings Screen
Unit ID - Uniquely identifies the radio for Flashcall
signaling.
Download ID
- This ID must be received by the radio
for it to accept a download of its scrambling
parameters.
Kill ID
- This ID must be received by the radio for the
kill operation to occur.
Master Code
- Displays the master code used by the
scrambler. Two scramblers must be programmed
with the same master code to communicate. The field
is an 8-digit hexadecimal number (0-9, A-F).
Radio Group
- Sets the group number of the scram-
bler from 00-99.
Sync Code
- Scrambling sync code from 0-15. Two
scramblers must have the same sync code to
communicate.
Fleet Number
- Number from 0-15 used when
multiple fleets of scramblers are used.
Auto Turnaround Time
- Time from 0-7 seconds after
receiving a coded message that the scrambler ignores
the clear code switch setting and forces the coded
mode.
Acknowledgment Delay
- Delay time from 50-1550
ms before the scrambler responds to information
received from a controller.
System Delay
- Delay time from 50-1550 ms
between when the PTT switch is pressed and the
scrambler transmits data over the air.
Emergency Delay
- The amount of time the scram-
bler waits to send the emergency signal after the
emergency switch is pressed. No delay or a 0.5 sec
delay can be selected.
Tx Turnaround
- If selected, inserts a delay between
when scrambled information is received and then
transmitted. This delay allows scramblers in the
system to prepare for the new data.
ANI at Beginning of Tx
- If selected, sends a Flash-
call ANI at the beginning of every clear mode
transmission.
ANI at End of Tx
- If selected, sends a Flashcall ANI
at the end of every clear mode transmission.
Unit-to-Unit Paging
- If selected, enables a single
unit page.
Mute at Power On
- If selected, mutes the audio when
powered up until the radio transmits, receives a
Flashcall selective call, or OTAR reprogramming of
scrambling parameters.
Auto Location Update
- If selected, causes the scram-
bler to automatically send the user location every
time it changes.
Auto Status Update
- If selected, causes the scram-
bler to automatically send the user status each time it
changes.
Data Operated Squelch
- If selected, causes the
scrambler to mute audio when incoming Flashcall
data is received.
Mute After Emergency
- If selected, causes the
scrambler to mute the audio after sending an
emergency signal until the unit transmits.
