The SS4 communications module can be equipped with an RS 485
interface to establish a USS bus connection using the SS31 interface sub-
module.
The interface module is a 40 pin (dual-in-line) hybrid device which can be
inserted in the socket provided on the SS4 communications module.
When inserting the module, ensure that it is correctly aligned: The recesses
of the socket of the interface module (or pin 1, marked with a point) and the
socket on the SS4 (X51) must coincide.
• data transfer rate up to 1 Mbaud
• max. cable length dependent on the baud rate:
200 m at 1 Mbaud
• no terminating resistor
To enable the transmitter, the RTS signal must be set to „1".
This enable signal is generated using an appropriate jumper in the
connector of the SS4 communications module.
