NOTE:
Be careful with the pin orientation when installing the connectors and the cables. A wrong connection
can easily destroy your LCD panel. Pin 1 of the cable connector is indicated with a sticker and pin1 of the
ribbon cable usually has a different color.
4.2.1 Inverter Board Description
The inverter board supplies the high voltage signals to drive the LCD panel by converting the 12 volt signal
from the AR-B1380A into high voltage AC signal for LCD panel. It can be installed freely on the space
provided over the VR board. If the VR board is installed on the bracket, you have to provide a place to
install the inverter board into your system.
4.2.2 LCD Settings and Connectors
The AR-B1380A supports CRT color monitors, STN, Dual-Scan, TFT, monochrome and color panels. It
can be connected to create a compact video solution for the industrial environment. 1MB of RAM on-
boarded allows a maximum CRT resolution of 1024X768 and a LCD resolution of 640X480 with 64K colors.
For different VGA display modes, your monitor must possess certain characteristic drives to display the
mode you want.
