MASTER CLOCK SOFTWARE - Program Descriptions
The ES-102 is shipped with a CD that contains several "Setup" Programs. Some of those programs are discussed
below. All programs are described in the "Readme" file. It is suggested that one refer to the "Readme" file as it may
contain updates issued after this manual was published. This software is also available from our web-site at
"
www.ESE-WEB.com ". The DOS programs described below do not need to be used if the Windows

programs are
used. For Win 3.1, use the "16 Bit" programs. For Win 95/98/ME/NT/2000, use the "32 Bit" programs. The DOS
programs are in the form of separate command-line utilities. For the Windows versions, run the Setup.exe program.
After the Install Wizard runs, a shortcut to the executable file will appear in your Start Menu.
ESEGPS
This Windows

program synchronizes the computer system time to the Master Clock time, and provides a control
panel for adjusting various Master Clock functions. This program may be used to reinitialize the receiver if necessary.
This program opens as a "watch" icon in the System Tray. Click on this icon to open the Control Panel applet.
MASTER32
This Windows

program works with the ASCII time output (Format "A", "0" or "1"). It synchronizes the computer
system time to the Master Clock time. This program opens as a "watch" icon in the System Tray. Click on this icon to
open the Control Panel applet.
MCDOS.EXE
This DOS program will set the System Time and Date of a PC/Compatible computer from an ES-102 GPS Master
Clock when the machine is booted up. The line "MCDOS" should be added to your AUTOEXEC.BAT file. The file
MCDOS.EXE should be placed either in the root directory or where the current PATH can find it.
The program by default is set to use COM1. To set it to a different COM port, add the port number to the command
line:
MCDOS /2
The MCDOS.EXE program may also be invoked from the DOS prompt to set the time whenever desired. If you are
using the optional serial port command described above, you can make running the program easier by creating a
batch file to run the program:
COPY CON:T.BAT <enter>
MCDOS /2 <enter>
F6 (the function key) <enter>
Now, just typing T <enter> will set the time.
GPSINI.EXE
This DOS program is used to initialize the Time Zone, Time Delay and Cable Delay Compensation values. The Time
Delay factor is set to zero, and the Cable Compensation is set for 19 feet. Running the program will print full
instructions on screen for setting the time zone.
GPSHIFT(x).EXE
These DOS programs are used set the ES-102 to provide an advanced or delayed time output. This can be useful in
TV network situations to compensate for video satellite delays. The time is adjustable from 0 to +/- 400 milliseconds,
in increments of 1 millisecond. Determine which COM port you have available and use GPSHIFT1.EXE for COM1:
and GPSHIFT2.EXE for COM2:. To set a 1/4 second delay using COM1:, for example, type GPSHIFT1-250 then hit
the ENTER key.
GPSCBL(x).EXE
These DOS programs are used to compensate for antenna cable delay, adjustable from 0 - 22215 feet. Determine
which COM port you have available and use GPSCBL1.EXE for COM1: and GPSCBL2.EXE for COM2:. To
compensate the unit for 200 feet using COM1:, for example, type GPSCBL1 200 then hit the ENTER key.
NOTE: All of these settings are remembered by the ES-102, even if powered down with the battery off.
GPSTIME.EXE
This DOS program is used to set the Time and Date of the unit in the absence of a satellite signal.
