1. XStreamRS‐232/485RFModem

The XStream-PKG-R RF Modem provides long range data

communications and advanced networking for OEMs and system

integrators. Out-of-box, the modem is equipped to sustain long range

wireless links between devices. Simply enter serial data into one

modem and the data surfaces on the other end of the wireless link.

The modem transfers a standard asynchronous serial data stream

between two or more modems. Its built-in RS-232/485/422 interfacing facilitates rapid

integration into existing data systems.

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.

1.2a. DIP Switch

Figure1.2. BackView

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]

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 [p21].

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].
