System Connection Diagram
The following diagram illustrates how the GPS repeater system is utilized
Mounting Installation
This GPS signal transmission system is designed to be setup by professional communications systems
installers.
Remote model GPSR400 should be mounted securely using the four enclosure mounting brackets provided.
GPSR400 remote units should be mounted flat against a wall or column with connection panel at bottom.
Provide adequate space of at least 1 foot at the bottom for all system connections.
In a well structured support wall that it is reinforced with a 3/4 inch thick plywood of additional backing,
mount the enclosure using four (4) M10 screws (not included) to bear the unit weight.

Cables
Follow these steps for connecting and disconnecting RF and optical fiber cables to the unit. Make all connec-
tions before powering up the remote unit.
Connect fiber optic and RF cables as shown in the System Connection Diagram.
It is recommended that the companion Head End Unit has been properly installed, Fiber-Fed, and Pow-
ered ON before Installing the Remote unit. Please refer to Head End Unit User Manual.
If Head-End unit is not installed, skip the Fiber LED status verification in the “LED/System Verification”
section.
Sequence to connect:
1. Connect System Ground.
- The remote unit comes with a .25-20FLANGENUT grounding lug. A grounding wire of suitable
gauge must be used to ground to a common bus bar in the Telecom room according to local and
building regulations.
2. Connect GPS Antennas to ports GPS In 1, GPS In 2, GPS In 3, and GPS In 4.
- Two (2) antennas required for operation.
- Apply coupling torque of 5 Nm to 4.3-10 connectors
- Only use operator approved GPS Antennas

3. Connect Singlemode duplex fiber with Duplex LC/UPC Interfaces to optical port F/O 1 (Other Interfaces
available)
- Fiber length must be shorter than 2km Please contact Sales for other fiber length requirements
- Clean fiber before connecting
- Optical ports can be connected in any manner
- Only one optical fiber connection needed for operation.
- Recommended second fiber connected to optical port F/O 2 for redundancy.
4. (Optional) Connect Ethernet Cable to the unit’s Ethernet Local port
Local/Debug port used for on-site debugging while maintaining connection to the NOC (Network
operations center)
Note: Both Ethernet ports on the GPSR400 are a transparent bridge. Both Remote Unit and Head-
End supports Ethernet over CPRI. Either unit can provide a local network connection to the other. See section
“System Configuration and Operation”
DO NOT CONNECT THE REMOTE UNIT AND HEAD-END TO THE SAME SWITCH. CONNECTING BOTH UNITS ON
THE SAME LAN WILL CREATE A BRIDGE LOOP
