The application connector features a standard Anybus-S 2kbyte parallel interface. For further informa-

The module supports 2Mbit/s and 500kbit/s operation. To select the
desired baud rate, just move the jumper cap to the corresponding loca-

The baud rate must be selected before power on, i.e. it must not
be changed during normal operation.

This product is a member of the Anybus concept of interchangeable fieldbus modules. This makes it
fully interchangeable with any Anybus-S supported fieldbus system with only little or no hardware and
software adjustments.
