Serial Commands

With serial commands, ASCII command strings are sent to the INDEXER Module through RS-
422 or RS-485 communications and these commands are interpreted and executed immedi-
ately. You can use general-purpose serial communications (RS422/RS485) to perform indepen-
dent control of up to 16 axes from one host controller (e.g., PC or HMI).
