Figure B-1: Basic Back-to-Back Test Configuration
After connecting and powering one, the front panel LEDs can be observed to verify that the Link
and Status LEDs are both green. If they are green, the radios are communicating and all radio-
related alarm conditions are normal.
It can be beneficial to have a computer to verify configuration in case of red LEDs or to pre-
configure the radio as desired for operation. Follow the instructions from the product manual on
how to connect the computer and configure the radio.
Alternatively, you may reset the radios to factory default configuration, which is performed by
holding the RMT button down while powering up. Hold the button down for approximately 5
seconds while applying power, and the radio is reset to factory default configurations. Perform
the reset for both ends, and the system should be operational in it’s default state. At this point,
you may reconfigure the radio, as necessary.
Note: If you have pre-configured the radios, the factory reset procedure will reset
the majority of your configurations. Do not reset the radios unless you have a
record of the desired configuration, or have downloaded the configuration file
from the radio first.
B-3 Specification Performance Verification
The specification performance verification is a more detailed test that allows you to verify that
the radio’s output power and threshold specifications are being met. This is typically a test that
would only be performed in a troubleshooting scenario, but can be performed before installation
if you wish to have a detailed record or be extremely certain of the radio performance before
installation.
This test is identical to the basic test, but in place of the fixed attenuation, it requires the use of
calibrated variable attenuation, or a set of calibrated fixed attenuators, or a combination of both,
adding to a total attenuation value of 120dB, as measured at the operating frequency of the radio
(roughly 2.4 GHz, in this case). In addition, a voltmeter or computer is also required.
Connect the system as in figure B-1, using the combination of fixed and variable attenuation in
between the radio’s RF ports. Connect the voltmeter to either radio’s RSL measurement port and
the associated reference ground connection.
