Introduction

ongratulations for purchasing the finest industrial-grade fast­poll modem available.

C

The Telenetics DSP9612 (Flash Poll) modem is a 9600/4800/0­1800 bps modem designed for 4-wire, full-duplex or 2-wire, half­duplex operation over a voice-band leased line or private line. The
modem is designed utilizing the latest digital-signal processing (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 and ITU-T V.23 modems.

The DSP9612 modem is ideally suited for multi-point communication
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 the DSP9612-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-line interface protected with heavy-duty surge protection

hardware (15KV).

 Requires no human intervention, making it ideal for unmanned

locations.

 Works within an extended temperature range of -40ºC to +85ºC.
 Designed with coupling transformers for high-voltage isolation

and common mode noise rejection in industrial and commercial
environments.

 Operate over voice-band conditioned 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 0-1800

bps.

 Easily accessible DIP switches for user configuration and option

selection.

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

 Local analog, local digital, and remote digital loopback

diagnostics.

Applications

Applications

The DSP9612 modem is designed for point-to-point and multipoint
data communications. Figure 1-1 shows 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-wire or 4-wire configuration

 Transmission line characteristics, noise, and line impairments

 Network configuration (point-to-point or multipoint)

 Number of nodes on the network

Unpacking Your Hardware

Your package should include:

 At least one of the following DSP9612 modems:

− Model DSP9612FP for 85 to 265 VAC

− Model DSP9612-LV for 10 to 53 VDC

 A leased-line cable

 A shielded DC power cable (model DSP9612-LV modem only)

 This User’s Guide

If your package contents are damaged or missing, please contact your
place of purchase immediately.

Additional Items You Need

To use your modem, you need the following additional items:

 Two- or four-wire transmission line or leased line

 A DB25-F data cable for your Data Terminal Equipment (DTE)

port

Page 9

Installation

 A power supply that provides either:

− 85 to 265 Volts AC, 50 to 60 Hz, single phase or 85 to

400 VDC (if you have the model DSP9612FP modem), or

− 10 to 53 Volts DC (if you have the model DSP9612-LV

modem)

Installation

Installation Summary

The modem installation involves the following steps:

1. Finding a suitable location for the modem. See the section below.

2. Configuring the modem. See page 13.

3. Connecting to a transmission line. See page 25.

4. Connecting to a voltage source. See page 27.

5. Connecting a DTE device. See page 28.

Finding a Suitable Location

The location you select should provide easy access to the back panel
communications interface(s) and front panel power interface. It should
also let you view all the LEDs on the front panel.

Note:

Telenetics also offers a rack-mount version of this modem
(Model DSP9612RM) as a plug-in module for the
Telenetics/UDS RM16M Central Site Modem Rack. For more
information, contact Telenetics Corporation’s Sales Department
at [phone].

Configuring the Modem

Configuring the Modem

You configure the modem using the three sets of DIP switches on the
bottom of the modem.

,

IMPORTANT

It is important to follow the three steps described
below, in the order shown, to ensure that you configure
your modem properly using the modem DIP switches:

1. Use DIP switch 3 (SW3) to configure the modem

for your host DTE interface and network topology.
Using SW3, you select the modem to operate in
high-speed fast-poll or low-speed (FSK) mode.

2. If you set SW3 for FSK mode in step 1, use DIP

switch 2 (SW2) to configure the modem for either
Bell 202T or ITU-T V.23 compatibility.
Otherwise, you can use the modem in fallback
mode.

3. Use DIP switch 1 (SW1) to select the modem’s

transmitter output level and receiver dynamic
range. The SW1 settings apply for both high-speed
fast-poll and low-speed (FSK) modes.

Installation

SW1 DIP Switch Settings

SW1 is an 8-position DIP switch. Table 2-1 shows the modem switch
settings for DIP switch SW1. A description of the SW1 switch settings
follows the table.

Note:

SW1 settings apply for both high-speed fast-poll and low­speed (FSK) modes
