Host-to-Interface Communications
SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command character sequence. When a command is valid, the
unit executes the command and sends a response to the host device. All responses from
the unit to the host end with a carriage return and a line feed (CR/LF = ]), which signals
the end of the response character string. A string is one or more characters.
Symbol Definitions
Symbols (variables), defined on the next page, are used throughout the Unit-Initiated
Messages section and the Command/Response Table for SIS Commands . The symbols
represent variables in the unit-initiated messages and the command/response table fields.
