2.1. Data Radio System Components

XStream Radio Modems are designed to provide long range wireless links between devices of 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.

2.1.1. 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 Ethernet-connected RF modem supports com port and Telnet connection options:

• Com Port Redirector Software enables legacy serial applications to communicate with the

Ethernet RF Modem by forwarding serial data over Ethernet.

• Telnet communicates directly to the Ethernet RF Modem using port 14001. Refer to the

“Test Communications (Telnet)” section [p

12] for an example that by-passes the com port.
