XStream-PKG-E™ Ethernet RF Modem – Product Manual v4.2A
RF Operation
Data Radio System Components
XStream Radio Modems are designed to provide long range wireless links between devices in a
data system. The PKG-E Ethernet RF Modem connects serial modems to Ethernet networks.
The following devices will be used to describe a data system that includes the XStream-PKG-E
Ethernet RF Modem:
XStream-PKG-E Ethernet RF Modem (“PKG-E”): The Ethernet RF Modem is
an Ethernet-connected serial modem used for communication with other
MaxStream serial modems. The Ethernet RF Modem is not a wireless Ethernet
Bridge intended for Ethernet connectivity on both the remote and base sides of
a wireless link.
XStream-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.
XStream OEM RF Module (“OEM RF Module”): The OEM RF Module is
mounted inside all XStream-PKG RF Modems and may be integrated into OEM-
designed products to transmit and receive data over-the-air.
System Description
The PKG-E Ethernet RF Modem can be used as an access point in a network of MaxStream RS-
232/RS-485 RF Modems (or other OEM RF Module Embedded Devices). XStream RF Modems
support point-to-point, peer-to-peer, point-to-multipoint and multidrop network topologies. Below
is an example of a typical point-to-multipoint application:

* The “OEM RF Module Embedded Device” represents any device that contains in it an XStream OEM RF
Module. This includes other XStream RF Modems (Ethernet, USB, RS-232/485 or Telephone) and any other
devices that contain in them an XStream OEM RF Module.
