Hints for Application
5.1. Master and Slave Operation
Set register “Mode” to position “Master” when the unit should generate the clock signal for
the encoder. In this case the clock terminals (CLK) are configured as clock outputs.

When your encoder receives already its clock from another device and the unit should only
“listen” to the communication, then set register “Mode” to “Slave”. In this case, both clock
terminals (CLK) are configured as inputs.

Set registers “Bits”, “Format” and “Baud” according to the encoder you use.
You are free to set any baud rate in a range from 0.1 kHz to 1000.0 kHz. For technical reasons
however, in the upper frequency range, the unit itself in master mode can only generate one of
the following Baud rates accurately:
1000,0 kHz
888,0 kHz
800,0 kHz
