Note) In case of RS-422 interface, multiple devices can be connected to one AS311 if the connected RS-422 devices work as slave stations and support multi-point connection. That is, the connected RS-422 devices must have the transmission generators which support the passive state. Also, the RS-422 devices must support the message format which contains the selecting address. In this case, the number of the connected RS-422 devices is limited up to 10.

On the other hand, the AS311’s transmission generator does not support the passive state. Therefore the AS311 must be the master station in the one-to-N configuration.
