Connecting the BA73A 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 LCD-Controller-A (PCI) and the

COM board (ISA). Ensure that the jumpers are set correctly. The inter-

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

chapter “Controller”.

When connecting the BA73A 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. An In-

stallation Instruction is delivered with the Wincor Nixdorf Order Unit “PC

Cable Set”.

Connecting the BA73A to the BEETLE /M

With a BEETLE /M containing a Celeron/Pentium III-CPU a LCD TFT

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

installed ex works. If you want to upgrade your BEETLE /M later, please

read the section “Installing the TFT adapter" at the end of this chapter.

If a TFT adapter-A is installed, a BA73A can be connected to the

BEETLE /M without assigning a slot. The connection of the adapter and

the display and the loudspeaker is effected via a 40-pin data cable. The

signals for the touch screen function and the source are effected via this

cable as well.

Before installing the display by using of the touch screen function please

note the following aspects:

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

loudspeaker on the screen display.
