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 field. No special characters are required to begin or end a command character sequence. When a command is valid, the unit executes the command and sends a response to the host device. All responses from the unit 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 an equipment power-up, occurs, the unit responds by sending a message to the host. The unit-initiated messages are listed below:

The switcher issues the Copyright message (above) when it first powers on. Vx.xx is the firmware version number and <date/time> is the date and time of the connection.

NOTE: <Date/time> are reported only if the connection is via the LAN port.

]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.

]Login Administrator]

]Login User]

The switcher initiates the Login message when a correct administrator or user password has been entered. If the user and administrator passwords are the same, the switcher defaults to administrator privileges.

Qik]

The switcher initiates the Qik message when a front panel switching operation has occurred.

Sprnn]

The switcher initiates the Spr message when a global preset has been saved from the front panel. nn is the preset number.

Rprnn]

The switcher initiates the Rpr message when a global preset has been recalled from the front panel. nn is the preset number.

InnnAudxx]

The switcher initiates the Aud message when a front panel input audio level change has occurred. nn is the input number and xx is the dB level.

Typnn•x]

The switcher initiates the Typ message when the video format for a video input is changed from the front panel. nn is the input number, • is a space, and x is the format: 1 = composite video, 0 = S-video.
