The Reset Switch is used to reset (re-boot) the RF module. This
switch only applies when using the configuration tabs of MaxStream’s
X-CTU Software.
LEDs indicate RF module activity as follows:
Standard female DB-9 (RS-232) connector.
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.
5-14 VDC power connector
DIP Switch functions are not supported in this release. Future down-
loadable firmware versions will support DIP Switch configurations.
