2.2. System Description
The XCite-PKG-U USB RF Modem is most commonly used as an access point in a network of serial
RF modems (such as MaxStream's RS-232/485 RF Modems). The XCite RF Modems support point-
to-point, peer-to-peer, point-to-multipoint and multidrop network topologies. The section below
illustrates a typical point-to-multipoint network application.
2.2.1. System Components
XCite Radio Modems are designed to provide long range wireless links between devices in a data
system. The following devices will be used to describe a data system that includes the XCite USB
RF Modem:
XCite-PKG-U USB RF Modem ("PKG-U"): The Ethernet RF Modem is an
USB-connected serial modem used for communication with other MaxStream
serial modems.
XCite-PKG-R RS-232/485 RF Modem ("PKG-R"): The RS-232/485 RF
Modem is a serial modem that can be identified by its DB-9 serial port and 6-
switch DIP Switch.
XCite OEM RF Module ("OEM RF Module"): The XCite OEM RF Module is
mounted inside all XCite-PKG RF Modems and may be integrated into OEM-
designed products to transmit and receive data over-the-air.

ule.
NOTE: XCite and XStream Radio Modems can seamlessly communicate data between each other. The
PKG-R units shown can therefore be from either product family. The primary differences between the
XCite and XStream radio modems are in range and configuration options.
