Mentor XL
•
Status
. Detail of the Status sub menu is shown below.
•
Receiver type
must be configured during installation.
o
Termination.
If the external receiver / antenna is feeding a pair of Mentor XL
reference generators, this parameter must be set to “terminated” for one SPG and
“unterminated” for the second unit.
o
Trimble / Non-Trimble
. Please set accordingly. We have not tested the
360-15-12 GPS Option module with other manufacturers’ receivers and some
adjustment of those products may be required.
•
PPS Lock
. If the PPS Lock mode is set to ON, it only affects the “Internal Free Run” mode of
genlock. The internal oscillator is then locked to the GPS reference.
•
On Start-up:
o
Crash Lock will cause sync timing to be very unstable until 1 PPS lock has occurred
although it will considerably speed up the process.
o
Time code Jam on first 1PPS lock will Jam the timecode clock to the RTC
automatically when a system is reset or powered on and it achieves its first
1 PPS lock. The Mentor XL will not Jam on subsequent loss and return of
1 PPS lock.
•
ATR Lock
. ATR (Absolute Time Reference) is explained in section 12.10. If ATR Lock Mode is
ON, the unit will also perform a fast lock, independently of the Crash Lock mode described
above.
•
Cable Length
. Provides compensation for the propagation delay of the antenna cable.
The GPS receiver has an automatic “site survey” function. A site survey can take some time to
complete and may occur during the initial installation phase.
