Connecting the BA71/BA72 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.

Plug the COM board into the corresponding AT terminal and plug the TFT

controller into the PCI terminal. Connect the COM5 and COM6 interfaces

of the COM board with the TFT controller.

The interrupts IRQ9 and IRQ10 are added for PC application only.

Connecting the BA71/BA72 to the BEETLE/M

As the BEETLE /M contains a C2-CPU there is no need for a controller but

for a TFT adapter which has already been installed at the factory. If you

want to upgrade your BEETLE /M later, please read the chapter “Installing

the TFT adapter" which is to be found at the end of this chapter.

If an TFT adapter is installed, a BA71/BA72 TFT can be connected to the

BEETLE /M without assigning a slot. The connection to the system s effec-

ted via a 50-pin data cable. The signals for the touch screen function and

the source are effected via this cable as well.

Before installing the display with use of the touch screen function please

note the following aspects:

In order to realize the touch screen function, several system settings

have to be effected.

The internal loudspeaker has to be pulled off in order to activate the

loudspeaker on the screen display.

The touch function has to be activated via a jumper (see also jumper

settings).

The COM2 interface has to be covered and may no longer be used

externally.
