RSSI
The first 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 AP is greater
than the configured RSSI Weak Threshold. If the RSSI to the AP is less than the RSSI Weak Threshold then 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
The second test is the Throughput Test which when enabled performs a basic throughput test between the AP and Client.
The configurable Remote Device IP Address should specify the IP Address of the AP
(Note that the on-board iperf server must be enabled at the AP 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 will be red, and while no data is being transferred the DIO LED will be 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 then the RS485 LED will be red; if the measured throughput is less than the Throughput Low
Threshold then the RS485 LED will be off.
Radio Path Test can be accesses by selecting the link from the “System Tools” page and then ticking the “Enable Radio
Path Test” and entering in appropriate thresholds levels to indicate RSSI and Throughput and the IP address of the Iperf
Server (normally the Access Point).
The following screen shot shows the indications you will see using the Configuration above.
The OK Led will flash between Red and Green which
indicates the module is in a diagnostic Radio Test Mode.
RS-232 Led is showing a green indication which means the
RSSI to the Access Point is greater than -40dB. If the RS232
Led showed Red it would indicate the RSSI level was
greater than -60dB.
RS-485 Led is showing a green indication which means the
Throughput to the Access Point is greater than 10 Mbps. If
the Led showed a Red indication this would mean the
throughput is between 10Mbps & 4 Mbps.
Radio Path Test can be accesses by selecting the link from the “System Tools” page and then ticking the “Enable Radio
Path Test” and entering in appropriate thresholds levels to indicate RSSI and Throughput.
