CHAPTER 2: Introduction

2. Introduction

With our V.35 Synchronous Modem Eliminator (SME), two synchronous

hosts that are not farther apart than 300 ft. (91.4 m) can communicate with

each other for a fraction of the cost of a pair of high-speed modems. The V.35

SME supports synchronous data rates of 32, 48, 56, 64, 72, 112, 128, and 144

kbps, and can be configured to emulate dialup or leased-line service. Timing

can be set for internal or external clock, and all necessary data, clocking, and

control signals are supported.

The V.35 SME implements the V.35 electrical interface on two standard

M/34 (“34-pin M-block”) female connectors. The unit draws its power directly

from the Request to Send (RTS) and Data Terminal Ready (DTR) signal leads

(Pins C and H) on both ports, so no AC power or batteries are required.

You can configure the V.35 SME’s behavior in several other ways. For

example, you can set it to keep carrier constantly ON or to have carrier follow

RTS; you can also set it to immediately respond to RTS with CTS or to

emulate an RTS-to-CTS delay of 7 or 53 ms.

V.35 SYNC MODEM ELIMINATOR

3. Configuration

The V.35 Synchonous Modem Eliminator has seven internal user controls—

one four-position DIP switch and six jumpers—with which you can configure

the unit for a wide range of applications. This chapter tells you how to open,

set, and reclose the V.35 SME, and describes all of the unit’s possible

configuration settings (including its factory defaults).

3.1 Opening the Housing

Before you go any farther, answer these questions:

First, will your devices be using the V.35 SME’s internal clock, and do you

want carrier constantly ON and an RTS-to-CTS delay of 7 ms (the factory-

default settings for these options)? If not, you will need to open both the

middle portion and the top of the Port-B end of the unit’s housing: Skip

ahead and follow the directions in Sections 3.1.1 and 3.1.2.

Second, will your devices be communicating through the V.35 SME at

32 kbps (the factory-default data rate)? If not, you will need to open just the

middle portion of the unit’s housing: Skip ahead and follow the directions in

Section 3.1.1 only (do not do Section 3.1.2).

If you are satisfied with all of the factory-default settings, you don’t need to

configure the unit at all; skip ahead to Chapter 4.

CHAPTER 3: Configuration

3.1.1 O

PENING THE

IDDLE

ECTION

Carefully insert a screwdriver, knife, or other tool with a very thin flat blade

into the seam along the side of the middle part of the V.35 SME’s housing

(the section with the model- and lot-number stickers). Gently twist the tool

until the all-plastic top and bottom panels of this housing section begin to

pop apart. (You will probably hear a snapping noise; this is normal.) If they

don’t come all the way off, carefully pry them the rest of the way off with your

fingers. See Figure 3-1 below.
