PRO CAT
MS/DOS to Yaesu FRG9600 Interface
Program
The FRG9600 has such a wide range of frequencys it can receive,
that it takes a computer to bring its capabilitys to practical
use. PRO-CAT is a professional quality interface written in the
"C" computer language, which is fast enough to allow almost any
MS/DOS computer full access to the FRG9600 power. Here is a list
of the hardware that is necessary for the interface.
1. MS/DOS computer with DOS 2.2 or better, 128K memory,
serial communications port, and game card adapter.
2. Yaesu FRG9600 CAT receiver.
3. Yaesu FIF232 interface device.
4. Standard RS232 patch cable with 25 pin connectors.
5. An IBM compatible joystick cable with 15 pin connector.
The RS232 connector that attaches to the computer may have to be
modified, and the joystick cable will need to be connected to the
CAT plug that fits into the back of the FRG9600. This will
require a knife, a soldering iron, and some electrical tape.
When You're done you might also want to buy a frequency directory
for your area. The services you can receive are limitless, you
may want to be careful about listening to cellular phone calls
though!
If you are using this program, and got it from me, then I have
your name and address. If you didn't, would you send me a postcard?
I like to know who's using PRO-CAT, be sure to include any comments
about your experiences with it!

The PRO-CAT CRT Display Explained
The parts of the PRO-CAT display are shown on the enclosed
diagram of the main menu, they are numbered 1 through 4.
1. Base frequency and limit frequency show the frequency range
that will be scanned when the s key is pressed. You can
change these limits by pressing the l key. The frequency
range will be scanned in 5 Khz steps.
2. This is the record number and description of the
selected memory record. As you can see, memory record 1
contains the frequency channels of the Oceanside police
department.
3. Each channel is listed here, and has a function key
designator to the left of it. If you press F10, in this
example, the FRG9600 frequency will be set to 467.975.
4. These are the commands available to you.
l - Changes the base frequency and limit frequency. The
FRG9600 display will flash each digit you enter
until you press the (enter) key. You can press the
backspace key to correct any frequency entered in error.
s - Begins a scan of the frequency range between base
frequency and limit frequency.
r - Allows you to call up a different record number.
Valid record numbers are from 1 to 100.
m - Begins a scan of the channels listed on the right
side of the display.
e - Allows you to add, change, or delete records in your
scan information file.
F1 to F10 - Press a function key to set the FRG9600
frequency to the value listed on the right side of the
computer display.
<shift> F1 - If you press the shift key and the F1 key at
the same time, the computer will allow you to change the
value associated with the F1 key temporarily. In this
example, you would enter a new value for 155.055. You can
change any of the function key frequencys by pressing the
shift key at the same time as the function key you want
to change.
<ctl> F1 - If you press the control key at the same time
that you press any function key, you can change the
frequency within that function key, and your changes will be
saved to disk.
PRO-CAT CRT Display (continued)
<shift> L - If you press the shift key at the same time as
you press the letter L , whatever frequency is displayed
on the FRG9600 at the time will be locked out of the scan
sequence.
<shift> C - If you press the shift key at the same time as
you press the letter C then all of the locked out frequencys
will be cleared.
<shift> S - If you press the shift key at the same time as
you press the letter S then you will change the scan step
of the scan. Steps of 5khz, 10khz, 25khz, and 100khz are
available.
<shift> m - If you press the shift key at the same time as
you press the letter m then you will change the mode used
in the scan. The program defaults to FM-N, except when the
frequency is in the aircraft band.
q - Allows you to quit to DOS.
Press the cursor right key -> to see these commands
on the video display main menu.
The Scan Information File
Scanning frequencys and descriptions are located in a file on
on disk called CATBASE.DAT. This file has to be located on a
floppy diskette in drive A: or B: for the program to find it. You
can use the DOS ASSIGN command to direct the program to drive C.
Here is a sample command >>> C>assign a=c <<<
The file has 100 records, you can initialize just one record or
the entire file using the database menu. When you initialize the
file or a record you erase its frequency information.
Updates to The Scan Information File
(The Database Menu)
Enter the Database menu by pressing the letter e from the main menu.
Option 1 - If you choose this option you can update any one of
the 100 records. First you select the record by holding down the
space bar until the requested record is displayed, then press the
enter key. You will then see all the frequencys available on that
record. The frequency you can change will be colored RED. As you
change each digit it will turn BLUE. You can backspace to correct
any errors. After entering frequency 10, key in a description for
this group of frequencys. Lower case letters look great, press
the enter key to finish.
Option 2 - This will allow you to clear one record, or the whole
file if you prefer.
Option 3 - This option calls up the Configuration Options Menu.
Option 4 - Prints the scan information file active records,
followed by a record cross reference to help you remember record
numbers when you're using the program.
The Configuration Options Menu
Here is the the last thing as well as the most important thing
you need to do to get your lazy FRG9600 receiver scanning
frequencys at a rate of 30 frequencys (or better!) per second.
Any program can make a rough guess of how fast a computer it's
running on, but you can do a much better job of it. The idea is
simple. The program has the default delays set for an IBM AT
style computer running at 8 Mhz. If you have a XT style computer,
then the datacomm delay will have to be reduced a little at a time
until the program scans fast enough to suit your taste. If you set
these delays to zero, however, rest assured that the FRG9600 will
not be able to handle the rate at which commands are sent from the
computer. If your computer has an adjustable clock speed, set it
to its slowest setting before adjusting delays, that will keep
computer generated noise to a minimum.
DATACOMM DELAY - This delay determines how much of a pause
to use between frequency set commands to the FRG9600. This
time is used to check the squelch for a possible signal on the
frequency.
CONVERSATION DELAY - When PRO-CAT is scanning, and finds a
signal on a frequency it has set, it will stop there, and resume
scanning the instant the signal drops below the squelch level.
This delay determines how long to stay on the frequency after
the signal drops below the signal level, in case the signal comes
back on frequency.
BLINK DELAY - When the program wants you to enter a value on the
keyboard, it will flash the FRG9600 display at you. If you are
entering a lower limit for example, the frequency will alternate
between 60.000 Mhz first and then 999.999 Mhz. Upper limits
alternate between 905.000 Mhz and 999.999 Mhz. This delay
determines how quickly these numbers alternate. Using this
system, you don't have to turn on your computer system monitor
every time you want to scan.
COMMUNICATION PORT - This option allows you to use a second
serial port for your FRG9600 interface, in case your COMM1 port
is being used for another purpose.
HARDWARE CONNECTIONS
1. Connect your computer's serial port to the Yaesu FIF232
interface device using a RS232 standard interface cable. This
cable has a 25 pin connector on each end. Use this cable,
and connect the unmodified DIN cable that goes from the FIF232
to the FRG9600. You should be able to change the displayed
frequency on the FRG9600 by pressing a computer function key
when PRO CAT is running. If the frequency on the FRG9600 display
doesn't change when you press a function key, modify the RS232
cable as follows. On the female connector, short pins
4 and 5 togather first, and then short pins 6, 8 and 20
togather. The pins are numbered on the connector.
2. There is also a DIN connector cable that goes from the Yaesu
FIF232 interface device to the FRG9600. You can either splice
into this cable for the joystick connection, or you can make
the joystick connection at the plug that fits into the FRG9600.
Connect the joystick lead that goes to pin 4 on the
joystick male connector (ground) to pin 1 on the CAT
plug (also ground). Then connect the joystick lead that
goes to pin 2 on the joystick male connector (normally the
joystick #1 fire button) to pin 6 on the CAT plug (BUSY).
This will allow the computer to know the FRG9600 squelch status.
