INSTALLATION PROCEDURE FOR THE DEVICE DRIVER
--------------------------------------------


You should have received one diskette:

   
An example installation would be the following:

1) Put the Controller software diskette in the floppy you are installing
   from (A: or B:)

2) Change to the floppy drive you are installing from (A: or B:)

3) type "install c:\comtrol"

4) type "D" (for directory) if asked if this directory specifies a 
   file name or a directory on the target.

This will place both the controller and system software into the
COMTROL subdirectory on your hard disk.


GETTING STARTED


Downloading the Controller
--------------------------

One file critical to downloading the controller is the CONFIG.DAT file.
This file contains information that the LOAD utility uses to actually
get the controller working.  Specifically, the LOAD utility will read
the text information in CONFIG.DAT and will use it start the controller
and download the control program.  The parameters in the CONFIG.DAT are
defined in the following order:


   o I/O address of the controller      (default is 218h)

   o Dual Port Memory address           (default is D0000h)

   o Interrupt Vector number            (default is IRQ 5)
   
   o Controller Data Bus Size           (default is 8)

   o Control Program starting address   (default is 4000h)

   o Turbo Debug Flag                   (default is 'N' or off)

   o Control Program name               (default is CP.BIN)

   o Number of lines on this controller (default is 8)






Actual downloading is explained below in the "running the
test application" section.  




Running the DOS test application
--------------------------------

If your Comtrol controller is already installed, you can use the
files in the \comtrol\bin directory to run a simple terminal emulator 
under DOS.  The best way to run this test program is to 
have an ASCII terminal connected to port 0 of the Comtrol interface
box with an RS-232 cable.  This will allow for both transmit and receive
testing.  The terminal should be configured for 9600 baud, 8 data bits,
1 stop bit, and no parity.

To run the test program, do the following:

1) Make sure the information in the config.dat file matches your controller,
   especially the I/O address and Dual Port memory settings.

2) From DOS, switch to the c:\comtrol\bin directory and run LOAD.EXE.

3) Then type TERM at the DOS prompt.


If everything went correctly, should should now be able to type on the
PC keyboard and see these keystrokes appear on the ASCII terminal. This 
is the transmit test.  By typing on the ASCII terminal keyboard, keystrokes
should appear on the PC screen.  This is the receive test.


All the files in the BIN directory must exist in the same subdirectory in
order for things to work properly.  For example, if you write a new 
control program, you must copy it to the BIN directory in order for it
to get downloaded.  There is nothing magical about this directory, and in
fact you may create your own "bin" directory.  However, the BIN directory
lists all of the files necessary to make a DOS application talk
to a Comtrol intelligent controller.





Running the WINDOWS test application
------------------------------------

If your Comtrol controller is already installed, you can use the
files in the \comtrol\bin directory to run a simple terminal emulator 
under Windows.  The best way to run this test program is to 
have an ASCII terminal connected to port 0 of the Comtrol interface
box with an RS-232 cable.  This will allow for both transmit and receive
testing.  The terminal should be configured for 9600 baud, 8 data bits,
1 stop bit, and no parity.

To run the test program, do the following:

1) Make sure the information in the config.dat file matches your controller,
   especially the I/O address and Dual Port memory settings.

2) From DOS, switch to the c:\comtrol\bin directory and run LOAD.EXE.

3) Type WIN to start Windows.

4) From the File Manager, switch to the c:\comtrol\bin directory.

5) Double click on WINTERM.EXE.


The Windows version of the terminal emulator only works on line 0.  If you 
want to try another line, make the changes in the c:\comtrol\app\winterm
directory, recompile, and move the new WINTERM.EXE file to the BIN 
subdirectory.

If everything went correctly, should should now be able to type on the
PC keyboard and see these keystrokes appear on the ASCII terminal. This 
is the transmit test.  By typing on the ASCII terminal keyboard, keystrokes
should appear on the PC screen.  This is the receive test.


All the files in the BIN directory must exist in the same subdirectory in
order for things to work properly.  For example, if you write a new 
control program, you must copy it to the BIN directory in order for it
to get downloaded.  There is nothing magical about this directory, and in
fact you may create your own "bin" directory.  However, the BIN directory
lists all of the files necessary to make an application talk
to a Comtrol intelligent controller.

How To Update Drivers Manually

After your driver has been downloaded, follow these simple steps to install it.

  • Expand the archive file (if the download file is in zip or rar format).

  • If the expanded file has an .exe extension, double click it and follow the installation instructions.

  • Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.

  • Find the device and model you want to update in the device list.

  • Double-click on it to open the Properties dialog box.

  • From the Properties dialog box, select the Driver tab.

  • Click the Update Driver button, then follow the instructions.

Very important: You must reboot your system to ensure that any driver updates have taken effect.
