38 XN-322-2SI-RS serial interface specialty module
The XN-322-2SI-RS module is an XN300 slice module with an RS-232
interface and an RS-485 interface.
The RS-232 interface on connector X1 supports transmission rates from 4,8
kbaud up to 115,2 kbaud and can be run with or without RTS and CTS
handshake signals.
Connectors X2 and X3 can be used to access the RS-485 interface. The
signals connected in parallel are intended for forwarding the RS-485 signal. In
addition, the termination for the interface (120  termination resistor) and
1k spread resistors can be activated in the configuration. The RS-485
interface is overvoltage-proof up to 15 V and can be run with transmission
rates from 4.8 kbaud up to 115.2 kbaud.
An external power supply is not required.
