User manual

The LCD-Controller-A/BA73A is a plug-in-controller with a PCI-interface.
There are two connections for
a 40-pin MDR connector with integrated COM5 output
a 9-pin DSUB female (for COM6)
COM5 and COM6 are only ready for operation when the optional
COM board is used.
The control data and data lines for the TFT LCD display are transmitted to
the 50-pin MDR connector via hardware drivers and filters. The cable,
which is linked up to the screen module, is connected to this MDR connec-
tor. The all-in-one cable length is up to 5 m. The COM5 interface signals
(for the Touch Screen) and the loudspeaker signal are also on this connec-
tor. A loudspeaker cable connects the beeper of the CPU to the loudspea-
ker connector of the controller. Please refer to the chapter “Installation” for
further information.
The screen panel next to the MDR connector has a 9-pin DSUB socket
connector, to which the COM6 interface is connected. This is the interface
with the power supply. This socket is always installed, but it will only work
with the Touch Screen version.
Please find a description of the COM board on page 11.
