The Host Computer
System Requirements
For proper operation of the Doors access control software, the host computer operating the
software must meet the following requirements.
• PC compatible computer using a Pentium-90 or faster microprocessor
• minimum of 16 MB of system RAM
(1)
• 520 KB of free, conventional memory
• VGA color monitor with VGA graphics card
• 3.5 inch floppy disk drive
• keyboard
• mouse or other pointing device
• 20 MB of hard disc space
• COM port
(2)
with a 16550 UART to support an external modem or a direct RS-232 serial
connection, or an internal 9600 baud (or faster) modem
• one of the following operating systems:
Windows 3.11
(3)
with MS-DOS 6.2 (or greater)
Windows 95
Windows NT
NOTES
(1)
The larger the number of cards being enrolled, the larger the system RAM should be to
efficiently handle the card database.
(2)
Since all communication between controllers and the Doors software is done through the
host computer's COM port, Doors cannot work if the host computer's COM port is not
working correctly. Keri Systems cannot be held responsible for host computer COM port or
hardware problems. With the Doors software package, Keri Systems, Inc. provides a simple
COM port test that can verify basic operation of the COM port. Please refer to the COMTEST
Program section below for instructions on operating the program.
(3)
This must be the Windows 3.11 upgrade version and not the older Windows 3.0 or 3.1
versions. There are features and improvements made in the 3.11 revision that the Doors
program needs for proper operation. To determine which revision of Windows is on a host
computer, click on the Help/About pull-down menu in the main program window. A text box
will appear listing a variety of information regarding the host computer, including the revision
of the Windows software. If necessary, contact Microsoft or a computer software vendor for
operating system upgrades.
