Now that the radios are paired, the
Range Test
tab can be used to perform a Loopback test (
RS232 Only
) to confirm the
radios are paired and transmitting data.
1. On the first unit (client) jumper pins 2-3 together to tie RX and TX (loopback) using female to female pin jumper wire.
Alternatively, a serial loopback plug (example: SeaLevel DB9 Female Serial Loopback Adapter) can be used.

2. Connect power to the first radio (client) and make sure that it is at least five feet away from the second unit (server).
3. With the second unit still connected to the Configuration Utility via the PC, click on Range Test tab.

Note
: Testing CL4490-1000-RS485 configurations with Range Test Tab requires two RS485-to-USB (or RS485-to-
RS232) adapters, so that both radios can be connected to the Configuration Utility, as RS485 does not support
Loopback configurations. See the
Laird Configuration and Test Utility Software - RAMP Modules User Guide
for additional information about using the Range Test feature for alternate testing options.
