Service interface active
The service interface is activated via a bridge between the pins 7 and 15 on the 15-pin sub-
D connector. If the BPS 37 is operated with a connection unit, the service interface is acti-
vated through a switch in the connection unit.
Connection
You can connect a PC or terminal to the BPS 37 via the serial interface and configure the
BPS 37 through this connection. For this, you need a crossed RS 232 connection cable (null
modem cable) that provides the connections RxD, TxD and GND. The hardware handshake
at the service interface is via RTS. A CTS handshake is not supported.
If the BPS is connected to a connection unit, you can use the 9-pin sub-D service connector
in the connection unit. For the respective connection specifications please refer to the data
sheet of the connection unit.
