3.10 Test Cable

The alignment procedure is optimized through the use of the provided test cable. This

st cable is designed for use with a digital voltmeter (not provided) to read the Link

Quality and Receive Signal Level (RSL) voltage generated by the radio’s receiver.

1. To read the RSL value of the radio, insert GND (ground) and RSL banana plugs

into the voltmeter. Note the RSL voltage. The voltage may be fluctuating; in this

case, note the maximum value seen.

2. To read the Link Quality value of the radio, insert GND (ground) and QUAL

banana plugs into the voltmeter. Note the Link Quality voltage. After the radios

have performed an auto calibration the quality voltage should read 3.0-3.3v if the

link is aligned on the main antenna beam and there are no obstructions (i.e., trees,

buildings, etc…) in the path, the link distance is within the operating parameters of

the radio (see Section 2.4 above), and it is not raining heavily.
