Host-to-Switcher Instructions
The switcher accepts SIS (Simple Instruction Set) commands through the rear panel
Remote RS-232 port, the front panel Configuration port, and the rear panel Ethernet (LAN)
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).
The switcher does not expect a response from the host, but, for example, the host program
might request a new status.
