2.1. Data Radio System Components

MaxStream RF Modems were designed to provide reliable wireless links between devices contained

in a data system. The PKG-E Ethernet RF Modem allows integrators to connect the MaxStream

Modems into an Ethernet network.

The following devices will be used to describe a data system that includes the XTend-PKG-E Ether-

net RF Modem:

XTend-PKG-E Ethernet RF Modem ("PKG-E"): The Ethernet RF Modem is

an Ethernet-connected serial modem used for communication with other Max-

Stream serial modems. The Ethernet RF Modem is not a wireless Ethernet

Bridge intended for Ethernet connectivity on both the remote and base ends of

a wireless link.

XTend-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.

XTend OEM RF Module ("OEM RF Module"): The OEM RF Module is

mounted inside all XTend-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). XTend 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 Loopback)" section [p12] for an example that by-passes the com

port.
