Page 6: Chapter 1 Introduction
The modem is also backward compatible with Bell 202 and ITU-T V.23 modems. The SM19202FP is the most technologically advanced modem on the market. Boasting a fast DSP processor and automatic adaptive equalizer, the SM19202FP modem is ideally suited for multi-point communication systems that require fast response time, short training time, and low throughput delay. -
Page 7: Features
The SM19202FP modem is specifically designed for harsh environments typically associated in utility substations and industrial facilities. Though functionally similar to commercial modems, the SM19202FP provides the following unique features that make it well suited for utility and industrial applications. -
Page 8: Applications
Introduction Applications The SM19202FP modem is designed for point-to-point and multipoint data communications. Figure 1-1 shows a typical point-to-point configuration using the SM19202FP modem and Figure 1-2 shows a typical multipoint configuration using the SM19202FP modem.

RTS is asserted by the RTU to the SM19202FP-K modem. The modem will use the delayed Clear-To-Send (CTS) as the indicator to the RTU to signal the start of sending data to the host end. -
Page 18: S1-9 − Remote Loopback Enable
Installation If you use the modem with transmission lines that are transformer-coupled or with an impedance-isolated network (such as a transformer bridge), set switch S1-8 OFF for proper operation. S1-9 − − − − Remote Loopback Enable S1-9 ON = Loopback enabled S1-9 OFF = Loopback disabled (default) During instances of channel noise, the modem may mistake a received preamble as a request to go into remote digital loopback. -
