UGPS Power Source Configurations
The UGPS module may be powered by an external source via the UGPS External Power Port.
Alternately, the UGPS may be powered by a PTP 230 backhaul master or PMP 450 Platform AP via
one of the UGPS Timing Ports. When the UGPS is powered by via one of the Timing Ports, the
radio provides the necessary power to enable 1 PPS synchronization timing and serial GPS
location data by the UGPS (which is sent back to the radio via the associated Timing Port). If the
UGPS is receiving power on the External Power Port (via 30V DC power supply or CMM port)
and
power on Timing Port 1 or Timing Port 2 simultaneously, the UGPS defaults to using the external
power supply.
External Power Only
Shown below are examples of external only powering for PMP 100 and PMP 400/430 units. In this
case the UGPS is powered via straight-through RJ-45 cable connected to a Cambium approved
30V DC power supply see
Table 27 Compatible 30V Power Supplies
. The UGPS
may also receive power through the RJ-45 Power Port via a power-over-Ethernet port on a CMM4.
The radios receive their GPS synchronization through a straight-through 6-pin RJ-11 cable
connected to either Timing Port 1 or Timing Port 2 of the UGPS.
