Range Test
The Range Test tab allows you to send data packets
between two radios and it reports the number of
successes and errors. (
Figure 8 )

Test Selection – There are six test options; each
uses one of the following hardware setups:
Setup #1: One radio is plugged into a serial or
USB port on a PC. The second radio is
plugged into a separate power supply
and has the Comm Select jumper set
to
Loopback.
Setup #2: One radio is plugged into a serial or
USB port on a PC. The second radio is
plugged into a different serial or USB
port on the same computer.
Setup #3: One radio is plugged into a serial or
USB port on a PC. The second radio is
connected to a serial or USB port on
another PC.
Figure 8: Range Test tab
If using two PCs for the test, the software on both sides should have the second COM port disabled on
the Settings tab.
