8 Bit Analog Inputs (transmitted in TxPDO 1 and TxPDO 2)

Serial Communication via RS-232
Independently from the CAN bus interface the communication can be carried out
through the built-in RS-232 interface. In order to do so a terminal program (e.g. Hyper-
Terminal on MS Windows) using the following parameters is needed.
Interface parameters:
Baud rate 38400 bits/second
8 Data bits, parity even, 1 stop bit
Protocol: Xon/Xoff
Terminal parameters:
ANSI emulation
By default raw data is output when the device is turned on respectively the monitor
mode is turned off. The update rate is 6 ms (the same as the output on the CAN bus
interface). The serial telegrams have the following configuration:
