D 244 430 00 & D 244 431 00 | 2-channel serial interfacesRS232/RS422/RS485, D-sub connection
The D 244 430 00 and D 244 431 00 serial interfaces enable the connection of devices with two RS232 or two RS422/RS485 interfaces. The devices connected to the D 244 430 00 / D 244 431 00 EtherCAT Terminals communicate with the automation device via the Coupler. The active communication channel operates independently of the higher-level EtherCAT system in full duplex mode with 300baud up to 115.2kbaud. The RS232/RS422/RS485 interfaces guarantee high interference immunity through electrically isolated signals. The D 244 431 00 can provide 2x 5V/20mA out of the E-bus supply (electrically isolated, short-circuit-proof) for the supply of external devices.
In conjunction with the TwinCAT Virtual Serial COM Driver, the D 244 430 00 & D 244 431 00 can be used as a normal Windows COM interface.
