Wireless Data Modems—Introduction

Wireless Data Modems

Wireless data modems connect to serial or Ethernet links and

transmit the data wirelessly. The modem controls the wireless

messages and data ports to provide a “transparent” data transfer.

Wireless Serial Data (Radio Modems)

• RS 232 and RS485 connections

• Industrial power supplies, industrial temperature rating

WI-MOD-9-D RADIO MODEM (SERIAL DATA)

• License-free operation in North and South America

• Wireless data up to 115.2 Kb/s

• 902-928 MHz, 1W, frequency hopping spread spectrum

• Typical line-of-sight distance 20 miles North America (4W ERP)

• One serial data port—

RS232 and RS485 connections provided

• Serial data up to 115.2Kb/s

• Configuration by Hayes AT commands

or Windows Configuration software

Modes of Operation

Transparent mode broadcast, “multi-drop” operation configurable

error-checking, unlimited repeaters (store & forward).

Controlled mode addressable point-to-point operation,

authentication and automatic re-tries, addressed

repeater routing.
