Introduction

ongratulations for purchasing the finest industrial-gradefast-Cpoll modem available.

The Telenetics DSP9612 (Flash Poll) modem is a 9600/4800/0- 1800 bps modem designed for 4-wire,full-duplexor2-wire,halfduplex operation over avoice-bandleased line or private line. The modem is designed utilizing the latestdigital-signalprocessing (DSP) technology to achieve high performance. The modem employs Telenetics’ proprietary modulation and encoding scheme to achieve fast modem training time. The modem is also backward compatible with Bell 202 andITU-TV.23 modems.

The DSP9612 modem is ideally suited for multi-pointcommunication systems that require fast response time, short training time, and low throughput delay. The DSP9612 is the most technologically advanced modem on the market.

This User’s Guide describes both the DSP9612FP (AC-powered)modem and theDSP9612-LV(DC-powered)modem. This manual is intended to let you get your modem “up and running” as quickly as possible. It contains all the information you need to configure and install your modem. It also contains troubleshooting information in the unlikely event you encounter a problem with your modem.

Introduction

Features

The DSP9612 modem is specifically designed for harsh environments found in utility substations and industrial facilities. Though functionally similar to commercial modems, the DSP9612 provides the following unique features that make it well suited for utility and industrial applications.

Packaged in a rugged, compact enclosure for industrial applications.

Leased-lineinterface protected withheavy-dutysurge protection hardware (15KV).

Requires no human intervention, making it ideal for unmanned locations.

Works within an extended temperature range of -40ºCto +85ºC.

Designed with coupling transformers for high-voltageisolation and common mode noise rejection in industrial and commercial environments.

Operate over voice-bandconditioned or unconditioned leased line and pilot wires.

Accepts power from a wide range of AC and DC power supplies.

DSP9612FP: 85 to 265 VAC or 85 to 400 VDC

DSP9612-LV:10 to 53 VDC

Standard industrial connectors for data, analog, and power interfaces allow reliable interconnection to other industrial equipment.

Asynchronous data rates (selectable) of 9600, 4800, and 0-1800bps.

Easily accessible DIP switches for user configuration and option selection.

DB25 connector for RS-232/V.24interface.

Local analog, local digital, and remote digital loopback diagnostics.

Applications

Applications

The DSP9612 modem is designed for point-to-pointand multipoint data communications. Figure1-1shows a typical multipoint configuration.

Figure 1-1.Network of Multipoint Configuration

There are a number of factors that can affect the network’s and modem’s operation and performance. These include:

Operating speed

2-wireor4-wireconfiguration

Transmission line characteristics, noise, and line impairments

Network configuration (point-to-pointor multipoint)

Number of nodes on the network
