SUBJECT: EQUITY It / MULTI-MODE VIDEO CARD - PARALLEL PORT SETUP
The purpose of this bulletin is to provide information on the set-
up procedure which is required to
allow correct
operation of the
parallel port
when using an Epson MULTI-MODE graphics card (MGA #
Q205A-AA) with the Equity It.
Although the
MGA card does not have a
parallel port physically
located on the card, it does contain the address location for
LPT1.
When the system DIP switches are set
to enable the primary
parallel port (DIP switch
set 2, 1 OFF - 2 ON), LPT1 is selected
and the system tries to send
the parallel
printer data to the
video board. In this case it would appear as though the parallel
port is not working as the printer will not print.
When using the MGA
video card
with the
Equity It,
the parallel
port DIP switches should
be set
in the SECONDARY position (DIP
switch set 2, 1 OFF - 2 OFF).
This will designate the Equity It
built in parallel output port as LPT1 and will allow the parallel
printer port to operate correctly.
An undocumented DIP switch setting exists (DIP switch set 2, 1 ON
and 2 OFF) which allows the built in parallel port
to function as
LPT2.
