Introduction
Congratulations for purchasing the finest industrial-grade fast-poll rack-mount
modem available.
The Raymar-Telenetics DSP9612RM (Flash Poll) modem is a 9600/4800/0-1800
bps rack-mount modem designed for 4-wire, full-duplex or 2-wire, half-duplex
operation over a voice-band leased line. The modem is designed utilizing the
latest digital-signal processing (DSP) technology to achieve high performance.
The modem employs Raymar-Telenetics’ proprietary modulation and encoding
scheme to achieve fast modem training time. It is also backward compatible with
Bell 202 modems.
The modem can be installed in an RM16M Rack (16 slots, 3U) or the RMX Shelf
(2 slots, 1U) from Raymar-Telenetics. The modem occupies only one rack slot,
eliminating the hassle of equipment trays and power bricks required for “Stand
Alone” modems. The modem is powered from the modem rack.
The DSP9612RM modem is ideally suited for multi-point communication
systems that require fast response time, short training time, and low throughput
delay. The modem is the most technologically advanced rack-mount modem on
the market.
This User’s Guide is designed to let you get your modem “up and running” as
quickly as possible. It contains all the information you need to install and
configure your modem. It also contains troubleshooting information in the
unlikely event you encounter a problem with your modem.

Features
Though functionally similar to commercial modems, the DSP9612RM provides
the following unique features that make it well suited for utility and industrial
applications.
Requires only one rack slot.
Operates over voice-band conditioned or unconditioned leased line and
pilot wires.
Operates without 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.
Asynchronous data rates (selectable) of 9600, 4800, and 0-1800 bps.
Easily accessible DIP switches for user configuration and option selection.
Local analog, local digital, and remote digital loopback diagnostics.
Applications
The DSP9612RM modem is designed for point-to-point and multipoint data
communications. Figure 1-1 shows a typical 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
Ancillary Documentation
For information about how to adapt an AC powered DSP9612RM modem to a
DC power operation, refer to the included documents (0062-0117-001). Also
refer to the RM16M Installation and Operation Guide (TEL-6200508506004).
