J1 connector using a 50–position IDC connector with custom
wiring. The Octagon Accessories and Expansion CD contains
wiring diagrams for some of the displays. Table A–10 shows the
pinout for connector J1.

Make sure the BIOS jumper is enabled — W1[1–2].
5.
Configure and program your Octagon CPU card for use with a
video card and monitor. Refer to your Octagon CPU card user’s
manual.

Due to loading of the Vee source, the Vee voltage will probably
require additional adjustments at this time in order to obtain
proper contrast. With the power on, re-measure Vee at J1 pin 25
and adjust R3 for the correct voltage.
Programming the 5445 EEPROM
The 5445/5445E card is factory configured and programmed to support
a standard VGA/SVGA monitor. If you are using the default monitor
and have not previously reprogrammed the 5445/5445E, skip this
section.
If you are installing the 5445/5445E in a Micro PC system and are
using a monitor/display other than VGA/SVGA, read the following
instructions. Programming the 5445/5445E requires that you boot the
Octagon CPU card from the BIOS drive, and establish a serial
communications link between your PC and the Octagon CPU card.
The following instructions assume you are using the 5445/5445E in a
Micro PC system.
1.
Make sure power to the 5445/5445E is off.
2.
Move the W1 jumper to position [2–3]. This disables the BIOS on
the 5445/5445E and allows you to use the serial port on your
Octagon CPU card.
