Interface

The ASDA-B series servo drive has two modes of communication: RS-232, and RS-485. All aspects of

control, operation and monitoring as well as programming of the controller can be achieved via

communication. However, only one communication mode can be used at a time. Users can select the

desired communication mode via SEL232/485 (pin6) of CN3 connector (Refer to Section 3.5.1).

Please refer to the following sections for connections and limitations.
