CMM Sync and UGPS Sync Cable
, two CMMs (two CMMmicros, two CMM4s, or a CMMmicro and a
CMM4) can be connected together with a CMM sync cable to provide either
•
The ability to have one GPS antenna support two CMMs
•
“Warm spare” redundant sync
Pinouts for the CMM sync cable are shown in
relative to the lock tab on the connector. When using a UGPS module for providing
synchronization pulses to a CMM4 unit, use the pinout configuration shown in
Figure 51
.
NOTE:
The CMM sync cable used to connect two CMMs for sync purposes has
different pinouts than the straight-through sync cable used to connect a
“remote AP” to an SM, or an AP or BHM to a CMM2.
