Troubleshooting an RPI

COMPANION 200 Installation and Maintenance Guide
d. The TCM wiring length between the Base Station and the
Controller (or Base Station Module) exceeds 1200 m.
e. There is a faulty Controller, Base Station Module, or RPI.
f. The two-way dc loop resistance of the power pairs between
the Remote Power Interconnect (RPI) and the Base Station
exceeds 90 ohms. Measure the loop resistance with an
ohmmeter. If the resistance exceeds 90 ohms, install a
second power pair, or power the Base Station with a plug-top
power supply (see Appendix E).
g. The Base Station is faulty.
4. Verify that the power cord of the RPI is properly connected to a
working ac outlet. If the Base Station is powered locally, verify
that the power supply is properly connected to a working ac
outlet and that the power supply cable is properly connected to
the Base Station power connector
5. If an external antenna is installed, verify that the external antenna
co-axial cable is properly connected to the BNC connector of the
Base Station and that the corresponding radio is programmed to
have an external antenna (see "Radios" in the section
"Programming the COMPANION 200").
To troubleshoot an RPI, follow these steps:
1. Verify that the Controller is ON.
2. Verify that the RPI is plugged into a working ac outlet.
3. Verify that all the connections (power cord, jumper lead, input
and output, etc.) to the RPI are correct and secured.
4. Verify the power cord fuse.
5. Verify the Base Stations:
a. Verify that the green light is ON.
b. Verify that the red light is not solid.
A solid red light indicates that both radios on the Base
Station are busy, that the Controller is downloading data into
the Base Stations, or that one or both radios have not been
assigned to a cell.
c. Verify that the red light is not flashing.
