1.0 Purpose

The purpose of this test is to familiarize new users with this product and allow
full understanding of its operation prior to field use. This test is divided into
two sections. The first test is performed “back to back” and eliminates all
other external parameters involved with HF communications. This test
requires only two modems and their respective computers. When the first test
has been successfully completed with proper data transfer in all required
modes, then proceed with the second test. The second test involves the HF
radio transceivers and must be done with careful attention to the correct fre­quency and power settings. Power output setting must not exceed 70 watts, as
higher power settings will only reduce reliability and will not enhance commu­nications.

2.0 Supplied Items

DC Power cable with 2.1 mm connector at one end
Audio cable
Serial extension cable RS-232 (9 conductor male one end - female other end)

DIN 8 pin plug with cable attached

Procomm 2.0 for DOS shareware communications software
GUI (Graphical User Interface) V1.67 for Windows Operating System

3.0 Installation Procedure for Back to Back Testing

Connect RADIO 1 Port of one Modem to RADIO 1 Port of the other using 8
Pin connector (cable supplied). Connect 9 pin straight thru cable supplied to
HOST COMPUTER connector and a PC comm port. Connect DC voltage to
both modems using the supplied cables. See figure 1 on page 2.

4.0 Program Setup

The following are the steps required to install the SG-7200 GUI control pro­gram. This program requires either Window 3.1 or Windows 95/98.

4.1 Program Requirements

This program requires a 386/16mhz or faster CPU, 8 Mega byte of
memory and Windows 3.1 or Windows 95/98 (preferred). At least 2
megabyte of available hard disk space is required for program installa­tion.

4.2 Software Installation

The following steps should be followed for program installation.

1. Place distribution disk into the floppy drive.

2. Using the Run Option in the Files Menu (Win3.1) or the Start Button
(Win95/98), select the floppy drive and execute the SGCXXX.EXE
