Description
The RS422/CAN/RS485 interface module allows you to connect to wired networks via one of three interfaces. Moreover, to connect to the RS485 bus, the device does not require hardware flow control, which is achieved by using a related CAN interface driver with extended levels of performance and security compared. The physical connection to external devices of CAN and RS485 interfaces is performed using a two-wire scheme with a shielded twisted pair, and RS422 interfaces are performed using a four-wire scheme with two shielded pairs A and B, Z and Y. If needed, terminators and pull-up resistors are installed on the outer devices of the bus; protective grounding of the bus is performed on one side.
