Getting Acquainted

Introduction

Radio modems provide wireless data communication between remote systems in
situations where wireline communication is difficult or impossible. For field
operations such as remote monitoring and control, DGPS, and data telemetry,
the radio modem provides the ideal link between remote computers, instruments
and other RS-232 devices.

The PDL Base is a high-speed, radio modem designed for field, mobile or office
operation. At the heart of the PDL is a high quality, multi-channel telemetry radio
engineered specifically for data communications. Using a simple 3-wire RS-232
interface, the PDL can easily be connected to most computers and instruments to
provide an efficient and reliable data link.

To meet the needs of a variety of applications, the PDL can be configured with an
IBM-PC compatible computer. Operating parameters such as data transmission
rate, mode, and others can be configured quickly without having to modify the
modem hardware.

customer support with quick and efficient service. We understand that your
