IIC-Bus Keyboard Module
The module is based on a PCF8574 port extension forming a 4x4 matrix.
The IICBUS support of the M2.0 operating system makes the decoding of
the 16 Buttons quite simple.
Sample programs for all units provide subroutines for this module
which allow you to use this module with a minimum of programming effort.
The keyboard is connected to the Applicationboard or direct to the Unit M2.0
and needs no separate power connection.
You need the connector cable (198876) for this connection. If you like to connect more
IICBUS components, the expander (191193) is suitable
