1.1b. I/O & Power LEDs
The LED indicators visualize diagnostic status information. The
modem’s status is represented 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, off briefly during RF transmission)
1.1c. Serial Port (DB-9 Connector)
Standard female DB-9 (RS-232) DCE connector – This connector
can be also used for RS-485 and RS-422 connections.
1.1d. Power Connector
7-18 VDC Power Connector (Center positive, 5.5/2.1mm) – Power
can also be supplied through Pin 9 of the DB-9 Serial Port.

NOTE: In cases where AT Commands should not be sent each time
the RF Modem is powered-on, the processor must be disabled by
populating J7 on the interface board inside the modem [see p19].
1.2b. Config (Configuration) Switch
The Configuration Switch provides an alternate way to enter “AT
Command Mode”. To enter “AT Command Mode” at the RF
modem’s default baud rate, hold the Configuration Switch down
while powering on the modem using the Power Switch [1.1a].
1.2c. Antenna Port
The DIP Switch automatically configures the XStream RF Modem
to operate in different modes. Each time the modem is powered-
on, intelligence inside the XIB-R interface board (inside the
modem) programs the modem according to the positions of the
DIP Switch. [See figure below for DIP Switch settings]
