IP6022-Bxxx | 1-channel serial interface, RS422/RS485

The IP6022 serial interface module allows the connection of devices with a RS422 or RS485 interface. The module transmits the data in a fully transparent manner to the higher-level automation device. The data is transferred via the fieldbus using a simple handshake protocol. This does not have any effect on the protocol of the serial interface. The active serial communication channel functions independently of the higher-level bus system in full duplex mode at up to 115,200 baud, while a 128 bytes receive buffer and a 16 bytes send buffer are available. The transmission of differential signals according to RS232 guarantees high immunity to interference through electrically isolated signals.
