This section describe synchronization options for PMP and PTP configuration.

This Sync Input parameter can be configured under Sync Setting tab of Configure > General page

(see General configuration on page 7-70).

PMP/PTP 450i Series has following synchronization options:

 AutoSync

 AutoSync + Free Run

 Generate Sync

 Free Run Before GPS Sync

Figure 123 Sync Setting configuration

AutoSync

For PTP, the BHM automatically receives sync from one of the following sources:

 GPS Sync over Timing Port (UGPS, co-located AP GPS sync output, or “Remote ” Device feed

from a registered SM’s GPS sync output)

 GPS Sync over Power Port (CMM4)

Upon AP/BM power on, the AP/BHM does not transmit until a valid synchronization pulse is

received from one of the sources above. If there is a loss of GPS synchronization pulse, within two

seconds the AP/BHM automatically attempts to source GPS signaling from another source.

In case of PMP, when there are synchronization sources on both the timing port and the power

port, the power port GPS source is chosen first.

If no valid GPS signal is received, the AP/BHM ceases transmission and SM/BHS registration is lost

until a valid GPS signal is received again on the AP or BHM.

Note

After an AP reboot, the sync acquisition takes a little longer than it had on 450i

(anywhere from 40 seconds to 120 seconds difference).
