B-11a. I/O & Power LEDs
FigureB‐11. FrontView LEDs indicate RF module activity as follows:
Yellow (top LED) = Serial Data Out (to host)
Green (middle) = Serial Data In (from host)
Red (bottom) = Power/Association Indicator (Refer to the D5
(DIO5 Configuration) parameter)
B-11b. RSSI LEDs
RSSI LEDs indicate the amount of fade margin present in an active
wireless link. Fade margin is defined as the difference between the
incoming signal strength and the module's receiver sensitivity.
3 LEDs ON = Very Strong Signal (> 30 dB fade margin)
2 LEDs ON = Strong Signal (> 20 dB fade margin)
1 LED ON = Moderate Signal (> 10 dB fade margin)
0 LED ON = Weak Signal (< 10 dB fade margin)
B-11c. USB Port
Standard Type-B OEM connector is used to communicate with OEM
host and power the RF module.
B-12a. DIP Switch
FigureB‐12. BackView DIP Switch functions are not supported in this release. Future down-
loadable firmware versions will support the DIP Switch configurations.
B-12b. Reset Switch
The Reset Switch is used to reset (re-boot) the RF module.
