Figure 86 Radio Path Tests
NOTE The Radio Path Test feature should not be enabled on a live system. It is intended for testing only.
Radio path settings are as follows.
Enable Radio Path
Test
Enables or disables the radio path test.
RSSI Strong
Threshold
Strong RSSI indication threshold.
RSSI Weak
Threshold
Weak RSSI indication threshold.
Enable Throughput
Test
Enables or disables the throughput test (independent of radio path test (RSSI).
Remote Device
IP Address
IP address of the remote device that you wish to path test.
Throughput High
Threshold
High throughput indication value. Generally configured with the desired throughput
level.
Throughput Low
Threshold
Low throughput indication value.
RSSI Test
The first test (RSSI Test) uses the RS232 LED to indicate the RSSI level from the access point. The LED will be
green when the RSSI to the access point is greater than the configured RSSI Strong Threshold, or red when the
RSSI to the access point is greater than the configured RSSI Weak Threshold. If the RSSI to the access point is
less than the RSSI Weak Threshold, the RS232 LED will be off. When the Radio Path Test is enabled, the OK LED
will flash alternately between green and red, indicating that it is in a diagnostic mode.
Throughput Test
The second test is the throughput test, which when enabled performs a basic throughput test between the access
point and client. The configurable remote device IP address should specify the IP address of the access point.
NOTE The onboard Iperf server must be enabled at the access point prior to running this test.
The throughput test will run through a continuous cycle where data is transferred for 10 seconds, followed by
10 seconds of silence. The RS485 LED and the DIO LED are used as indicators of the throughput test. While data is
being transferred the DIO LED is red, and while no data is being transferred the DIO LED is off.
If the average throughput over the 10-second duration of the throughput test is greater than the configurable
Throughput High Threshold, then the RS485 LED will be green. Otherwise, if the throughput is greater than the
configurable Throughput Low Threshold the RS485 LED will be red. If the measured throughput is less than the
