This is the prototype TLV hardware and software:

    To install this package on an IBM PC or compatible system with a hard
disk drive, simply insert the distribution diskette into a floppy drive,
Enter the appropriate A: or B: command to switch to that drive, and type
"INSTALL". This will invoke the Micro-Installer program which will perform
all commands necessary to install the TLV files on your hard drive.

    NOTE: INSTALL is menu driven, and allows you to choose what portions of
the distribution package to install, and where to put them (directory). It
will warn you before installing over an existing directory, and does not
modify AUTOEXEC.BAT or CONFIG.SYS. It simply copies/dearchives the files from
the distribution diskette into appropriate directories on your hard disk.

Once installed, you will have the following files:

*1- All drawings are in DDS MICROCAD format. You can obtain MICROCAD
    from the EMBEDRAW.ZIP archive included on the DEMO disk, and also
    available from the DDS web site: http://www.dunfield.com

*2- The PC software source code must be compiled using the DDS MIcro-C/PC
    package, included on the DEMO disk, and also available from the DDS
    web site.

*3- The TLV controller firmware must be compiled using the DDS Micro-C
    8051 Developers Kit, available from Dunfield Development Systems.

*4- As this is not a DDS product, it does NOT fall under DDS standard
    technical support policy, however this document does provide useful
    information on how to contact DDS.


NOTES & ISSUES:
---------------
The Enable/Inhibit inputs on the controller are currently configured as
"Positive" logic. Ie, you have to set them to +5 to activate them. The
80C31 has internal pull-up's, so these signals naturally assume "ON".
If you turn on the "Inhibit" feature without grounding the inhibit input,
the camera will remain inhibited.

If you prefer, you can use the signals as simple contact closures to
ground by reversing the descriptions (ie: The Enable becomes !Inhibit,
and Inhibit becomes !Enable).
