XTIB-R RS-232/485 Interface Board
FigureB‐03. DIPSwitchSettingsoftheXTIB‐R(RS‐232/485)InterfaceBoard
B-01a. Config (Configuration) Switch
FigureB‐01. FrontView
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.
B-01b. I/O & Power LEDs
The LEDs visualize gigantic status information and indicate module
activity as follows:
Yellow (top LED) = Serial Data Out (to host)
Green (middle) = Serial Data In (from host)
Red (bottom) = Power/TX Indicator (Red light is on when
powered; it pulses on/off briefly during RF transmission.))
B-01c. DB-9 Serial Port
Standard female DB-9 (RS-232) connector. This connector can also
be used for RS-485 and RS-422 connections.
B-01d. 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-01e. Power Connector
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 Digi Technical Support to enable this option.
B-02a. DIP Switch
FigureB‐02. BackView DIP Switch automatically configures the module to operate in
different 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.
