The IR-Interface is claimed to be IEC 62056-21 mode C (asynchron, half-duplex, 300 - 19.200 baud, 7bit, even parity, 1stop (1_7D_1P_E_1S) and it is bidirectional. So one can also send something over that interface. There's an optional RS485 wire interface on some models. | The IR-Interface is claimed to be IEC 62056-21 mode C (asynchron, half-duplex, 300 - 19.200 baud, 7bit, even parity, 1stop (1_7D_1P_E_1S) and it is bidirectional.
