LEDs indicate RF module activity as follows:
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.
Standard Type-B OEM connector is used to communicate with OEM
host and power the RF module.
DIP Switch functions are not supported in this release. Future down-
loadable firmware versions will support the DIP Switch configurations.
The Reset Switch is used to reset (re-boot) the RF module.
