synchronization signals will also be transferred to the SYNC
OUT port.
b. If a BS-GU is a "slave", it will use the synchronization signals it
receives from the "master" via the SYNC IN port. It will also
transfer these signals to its SYNC OUT port for use by the next
slave module if applicable.
A slave module continuously monitors the lines from the GPS
antenna in its SYNC IN port. If it determines that proper PPS signals
are received (at least three consecutive PPS signals one second
apart), it will automatically revert to the regular operating mode,
using the PPS signals for generating its synchronization signals.
A master BS-GU must enter a special antenna recovery mode to
check the validity of the signals it receives from the GPS antenna.
The antenna recovery mode can be activated either manually or
automatically, using the GPS Antenna Recovery menu:
 Manual Recovery Mode - Enables to initiate a single antenna
recovery process during which the unit checks the signals it
receives from the GPS antenna. The manual recovery mode is
completely independent of the automatic recovery mode,
meaning that a manual recovery process can be initiated by the
user regardless of the selected option in Automatic Recovery
Option. Typically, manual recovery will be initiated after
connecting/re-connecting or fixing a problem in the GPS
antenna.
 Automatic Recovery Mode - Enables to control an automatic
recovery process:
 Automatic Recovery Option - To enable or disable
automatic initiation of antenna recovery process. If a GPS
antenna is not used, the Automatic Recovery Option should
be disabled.
The default selection is Enable.
 Automatic Recovery Interval - To define the time interval
between two consecutive initiations of automatic antenna
recovery processes.
Valid values: 5 to 1440 (minutes)
Default value: 15 (minutes)
NOTE:
During Antenna Recovery mode the master BS-GU module stops generating
synchronization signals for several seconds. Therefore, the rate of entering this mode
should be minimal.
NOTE:
The GPS Antenna Recovery menu is applicable only to a "master" BS-GU module.
