Host-to-Switcher Instructions
The switcher accepts SIS (Simple Instruction Set) commands through either serial
port and the 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 the connection is via a serial port or the switcher is in verbose mode 2 or 3,
and 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).

Password:
The switcher initiates the password message immediately after the copyright
message when the controlling system is connected using TCP/IP or telnet and the
switcher is password protected. This message means that the switcher requires an
administrator or user level password before it will perform the commands entered
via this link. The switcher repeats the password message response for every entry
other than a valid password until a valid password is entered.
