3.1 INTRODUCTION
The Johnson 2000 Repeater Program on 3.5 inch
disk, Part No. 023-9998-390, uses an IBM
computer to program the EEPROM Memory in the
Main Processor Card (MPC). To lessen the chance of
programming errors and simplify operation, the pro-
gram uses yes/no questions or toggles through the
available responses.
The computer is connected directly from the
serial card to the MPC. The interconnect cables used
are shown in Figure 4-29. The DB-9 to 8-pin modular
adapter is connected to the serial port of the computer
and an interconnect cable connects the adapter to the
MPC.
NOTE: These connections are for the IBM computer
and may differ from an IBM compatible. In which
case, consult the manuals for your computer for serial
card outputs and connections.
3.1.1 HOW TO USE THIS MANUAL
This manual introduces the program and illus-
trates how to use the features. This manual is orga-
nized to easily find programming information with the
Table of Contents, Index and Parameter Tables for the
responses required for programming.
Graphic reproductions of the screens are shown
for reference. Adjacent to the screens are tables to
provide the parameters, available responses and a brief
description of the parameter. It is not the intent of this
manual to teach computer operation, but to allow the
user to become familiar with the available screens and
the responses without having to be at the computer.
3.1.2 GETTING STARTED
NOTE: Before starting you should already know how to
start MS-DOS
, format and make backup copies of
disks, copy and delete files, and run programs. If you
are unfamiliar with any of these actions, refer to the
MS-DOS manual for your computer for more informa-
tion (see Section 5-1).
SECTION 3 SOFTWARE
disk. The MS-DOS Revision 2.0 or later operating
system is needed to run the programs. The computer
personal
needs to have RS-232C capability, for example, the
Serial Card in slot "COM1" or "COM2".
3.1.3 COMPUTER DESCRIPTION
an IBM PC or compatible computer that meet the fol-
lowing minimum requirements.
1. One 3.5" high density disk drive.
2. 640K of memory
3. MS-DOS version 2.0 or higher
4. One serial port
5. Monochrome or color monitor and video card
tain areas on the screen, a monochrome (black and
white) monitor or LCD laptop also provide satisfac-
tory operation. Most video formats such as EGA and
VGA are supported. A serial port is required to con-
nect the Repeater to the computer. This port is stan-
dard with most computers.
not included. With most computers, the adapter-to-
computer cable is a standard DB-25 M-F cable, PN
023-5800-017, (the male connector plugs into the
adapter). If your computer requires a male connector,
a male-to-male cable is also available, PN 023-5800-
016. The cable from the adapter to the Repeater has a
modular-type 8-pin connector (see Figure 4-29).
3.1.4 EEPROM DATA STORAGE

nonvolatile, data is stored indefinitely without the
need for a constant power supply. A repeater can be
