Connecting the BA72A to the PC

First ensure that the controller is switched off and the mains supply

plug has been pulled out. Then loosen the housing of the PC and

unscrew the panel. Take care in doing so that you do not tilt or jam the

housing in any way. For the connection to a PC please refer to the docu-

mentation delivered with your PC.

Use a free PCI/ISA slot for plug in the TFT controller (PCI) and the COM

board (ISA). Ensure that the jumpers are set correctly. The interrupts

IRQ9 and IRQ10 are provided for PC applications. See also the chapter

“Controller”.

When connecting the BA72A to a standard PC observe the compatibility

by tests.

The LCD controller with “Touch in” is installed in PC that provide only PCI

slots. A COM interface of the PC is used for the touch function. It is con-

nected to the COM interface of the controller via a separate cable.

Connecting the BA72A to the BEETLE /M

With a BEETLE /M containing a Media GXm-CPU or a Celeron-CPU a

LCD TFT Adapter-A can be installed instead of a TFT Controller-A. The

adapter is installed ex works. If you want to upgrade your BEETLE /M la-

ter, please read the section “Installing the TFT adapter" at the end of this

chapter.

If a TFT adapter-A is installed, a BA72A can be connected to the BEETLE

/M without assigning a slot. The connection to the system is effected via a

40-pin data cable. The signals for the touch screen function and the sour-

ce are effected via this cable as well.
