The uGPS is no longer shipping as of December 2018. It has been replaced with cnPulse. Refer to the cnPulse knowledge base for more information.
Use the following procedure to install the UGPS module and to verify operation.
|
Step |
Action |
|
1 |
Pole mount or surface mount the GPS antenna following the installation guidelines and specifications listed in this chapter. |
|
2 |
For PMP 100/400/430/450 and PTP 100/200 series, configure (via web management interface) the access points/backhaul masters to sync to received GPS signal (via the timing port). Navigate to Configuration > General and set the Sync Input to Sync to Received Signal (Timing Port/UGPS). Since the UGPS will be configured with an external power source, set the UGPS Power value to Disabled. Configuring the sync input and disabling UGPS power - PMP 100/400/430 and PTP 100/200 series
For PMP 320 series, configure (via web management interface) the access point to sync to received GPS signal (via the AP’s RJ-11 port). Navigate to Configuration > Settings and set the Sync Source to UGPS and Serial Type to uGPS. Configuring the sync source - PMP 320 series

3 |
For PMP 100/400/430/450 and PTP 100/200 series, click Save Changes and reboot the radio. For PMP 320 series, click Update, click the Save icon and reboot the radio. |
|
4 |
If connecting the UGPS to a CMM3 or CMM4, configure the CMM (via the CMM web management interface) to Slave mode (access points/backhaul masters connected to the CMM will need to be set to receive GPS sync signal from the power port). Navigate to Configuration > CMM and set Sync Source to Slave (RJ11 Port). A reboot on the CMM is required for these changes to take effect. |
|
5 |
Connect an RJ-11 6 pin cable from Timing Port 1 of the UGPS to the RJ-11 utility port of the access point/backhaul master to receive GPS sync signal. If applicable, repeat this step for additional access points and backhaul masters. If the UGPS is to send sync to a CMM, use a special sync cable. |
|
6 |
Install a 600SS surge supressor between the power supply and the UGPS module. |
|
7 |
Connect an RJ-45 8 pin Ethernet cable from the UGPS power port to the 600SS surge supressor. |
|
8 |
Connect an RJ-45 8 pin Ethernet cable from the 600SS surge supressor to the power supply. |
|
9 |
Verify on the access point/backhaul master/CMM that the GPS synchronization signal is being received properly. |
