•Using SIS Commands

•Command and Response Table

Communication Ports

The DVC 501 SD can be remotely controlled via a host computer or other device (such as a control system) that is connected to the rear panel RS-232 port or the front panel USB Config port. With an RS-232 or USB connection, you can configure and control the DVC using SIS commands.

The protocol for the rear panel RS-232 port is 9600 baud, 1 stop bit, no parity, and no flow control. See “Connecting to the RS-232 Port” in the “Installation” section for information on wiring to this connector.

See “Connecting to the USB Config Port” for information on making a USB connection.

Using SIS Commands

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. When the DVC determines that a command is valid, it executes the command and sends a response to the host device. Each converter 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.

DVC-initiated Messages

When a local event (such as a front panel selection) takes place, the converter responds by sending a message to the host. No response is required from the host.

The following converter-initiated message is displayed:
