Trouble Shooting

Should there be any difficulty in establishing a radio link, consider the following items:

1. Are all the units properly installed and wired?

2. Is DC power applied and are the power indicators illuminated?

3. Are the UHF antennas installed, aligned toward the distant end?

4. Are the UHF antenna polarizations the same at both ends?

5. Are the coax feedlines installed correctly? Check the return loss or continuity.

a. Return Loss should be 14 dB or greater. (VSWR 1.5:1 or less)

6. RSSI should be greater than -106/-104 dBm and best between -95 dBm and -60 dBm.

7. Are the UHF equipments properly coordinated? Units are configured to only communicate with the

intended coordinate end.

8. Have the MDS settings been changed? If so, confirm the correct settings.

a. Network Address and Direct Mode are important.

i. Set both ends the same.

b. The repeater end should be set as “Root” and receiver end set as “Node”.

i. If both ends are set the same, they will not communicate.
