RS-422/485 Serial

Standard serial interface for single and multidrop motion systems.

RS-422/485 serial interface for programming and control

SEM serial products support RS-422 (4-wire) and RS-485 (2-wire) serial communications interfaces and may be connected in either single or multi-drop networking configurations (party mode). In multi-drop mode, each serial node address is configured as an ASCII character consisting of A-Z, a-z or 0-9 for a total of 62 possible nodes in a serial network.

Serial networking resources


Serial communications methods to transfer data have been standardized for nearly half a century. RS-422 and RS-485 are balanced differential communications interface widely used in industrial networks for multi-drop and multi-point networks.

Lexium MDrive Pulse/direction and Motion Control units can be named using viewable ASCII characters. There my be up to 62 named nodes on a serial network.

Novanta IMS Motion Control products us the MCode programming language which uses 2-character mnemonic commands. Pulse/direction products use an intuitive GUI for configuration and setup. These are both available as open or closed loop with an internal magnetic encoder. Closed loop models feature hMTechnology.
