Host-to-Switcher Instructions
The switcher accepts SIS commands through the RS-232 ports and Ethernet port.
SIS commands consist of one or more characters per command field. They do not
require any special characters to begin or end the command character sequence.
Each switcher response to an SIS command ends 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-initiated messages are listed below
(underlined).
