14.2.1 RS485 Interface Operation
COM3 and COM4 interfaces can also be operated in RS422 mode as RS485 interfaces. This is
possible by a TriState switching, which is made using RTS.
14.3 CAN Interface
The B&R interface board is equipped with an Intel 82527 CAN controller, which conforms to CAN
specifications 2.0b. It is thereby possible to use standard protocols CAN and extended CAN.
B&R software supports the standard CAN identifier (11 bit).
The CAN controller can trigger an NMI (non-maskable interrupt).
