2.2 SYSTEM SETTING
Before installing the AR-B1042 VGA module, you should first configure the VGA board’s hardware. This section
describes how to make connections and configure the VGA board. You may find it is convenient to go through
these sections first before installing the VGA board into the PC/104 interface.
The AR-B1042 VGA module is a very versatile VGA controller that can be used for either CRT or LCD display. It is
very important that you go through the whole chapter before installation.
Before you actually plug the module into your PC/104 bus, you must first set the jumper pins to configure the AR-
B1042 module to your system requirements. This is done by closed the jumper pins with a jumper or leaving the
pins open.
Once you have installed the VGA card into the CPU’s PC/104 bus, you can start connect internal cables. The
internal cables are wire leads with plastic female connector that attached to the card’s connectors. The VGA
card’s connectors have many numbers of pins and are the points of contact between the CPU card and other parts
of the computer.
CAUTION: Before making connection on the board, make sure that power to the system is turned off.
Jumper pins allow you to set specific system parameters. Set them by changing the pin location of jumper blocks.
(A jumper block is a small plastic-encased conductor [shorting plug] that slips over the pins.) To change a jumper
setting, remove the jumper from its current location with your fingers or small needle-nosed pliers. Place the
jumper over the two pins designated for the desired setting. Press the jumper evenly onto the pins. Be careful not
to bend the pins.
We will show the locations of the AR-B1042 jumper pins, and the factory-default setting.
CAUTION: Do not touch any electronic component unless you are safely grounded. Wear a grounded wrist strap
or touch an exposed metal part of the system unit chassis. The static discharges from your fingers can
permanently damage electronic components.
