Host Interface 37 (114)
3.6 UART Operation
3.6.1 General Description
The serial interface is a common asynchronous serial interface, which can easily be interfaced
directly to a microcontroller or UART. It is provided for backward compatibility with the Anybus
CompactCom 30 series.
The serial interface is activated using the OM[0...3] inputs, which also are used to select the
operating baud rate, see Operating Modes, p. 16.
Other communication settings are fixed to the following values:
Data bits: 8
Parity: None
Stop bits: 1
Communication settings are fixed to asynchronous, 8-N-1, with bit order LSB first and without
hardware flow control signals.
It is not possible to build a synchronous application in this mode.
