Host-to-Device Communications
SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command sequence. When the scaler determines that a
command is valid, it executes the command and sends a response to the host device. All
responses from the device to the host end with a carriage return and a line feed
(CR/LF =
]
), indicating the end of the response character string (one or more characters).
