The Config Switch provides an alternate method for entering into
Command Mode. To enter Command Mode at the module's default RF
data rate, hold the Configuration Switch down for two seconds.
The LEDs visualize gigantic status information and indicate module
activity as follows:
Standard female DB-9 (RS-232) connector. This connector can also
be used for RS-485 and RS-422 connections.
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.
7-28 VDC power connector (Center positive, 5.5/2.1mm)
Note: The XTIB-R interface board can accept voltages as low as 5V.
Contact MaxStream Technical Support to enable this option.
DIP Switch automatically configures the module to operate in differ-
ent modes during the power-on sequence. Each time the module
assembly (interface board + module) is powered-on, intelligence on
the board programs the attached module according to the positions of
the DIP Switch.
Figure B-03 illustrates DIP Switch settings. Table B-02 summarizes
the configurations triggered by the positions of the DIP Switch.
