Checking the LED Indicators
When using LEDs to maximize the signal, you adjust the antenna until as many LEDs as possible are
turned-on and the rest are blinking as fast as possible. With all three LEDS turned-on, the signal is good
enough to support the maximum data rate.
Bridge Normal Mode LED Indications
During normal operation the bridge LEDs provide status information as shown in Table 5-3.
