SYNC TIME OUT
The
SYNC
command reads or sets the Sync Time Out period. A timer is started
whenever the receiver is not tracking any satellites. The timer is reset when the
receiver reacquires a satellite. A Time Sync Alarm is asserted if the receiver fails to
reacquire satellites within the allotted time out period. A Time Sync Alarm causes a
Major Alarm and removes outputs placed under SYNC Signature Control. To view the
current sync time out period, issue the
SYNC
command as shown below:
Type:
SYNC <ent>
Default Response:
TIME SYNC TIME OUT= 02:00:00
To change the sync time out value, place the clock in
Set Mode
and issue the
SYNC
command as follows:
Type:
SYNC HH:MM:SS <ent>
Where:
HH:MM:SS
= Hours:Minutes:Seconds
NOTE
: Due to alarm sequencing, Minor elevating to Major, the
SYNC time out period must be longer than the LOCK time out
period.
Example: Change the SYNC time out period to 8 hours.
Type:
SM ON <ent>
Response:
SET MODE ON
Type:
SYNC 08:00:00 <ent>
Response:
TIME SYNC TIME OUT= 08:00:00
