SIS Programming Guide
Host-to-SMX and SMX-to-Host 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 SMX determines that a command is valid,
it executes the command and sends a response to the host device. All responses from the
switcher 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.
Switcher-Initiated Messages
When a local event such as a front panel operation occurs, the switcher responds by sending
a message to the host. The switcher-initated messages are listed below.
