Remote Control

The VSC 150 can be remotely controlled via a computer or a control panel attached to the rear panel RS-232 connector. Alternatively, the VSC 150 can be controlled using the IR 601 infrared remote control. This chapter discusses how to use each of these options to control the scan converter.

RS-232 Remote Control

The VSC 150 can be controlled by a host computer or other control device via an RS-232 connection with a protocol of 9600 baud, 1 stop bit, no parity, and no flow control. The

Host-to-VSC communications

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command sequence. When the VSC 150 determines that a command is valid, it executes the command and sends a response to the host device. All responses from the scan converter 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.

VSC-initiated messages

When a local event such as a front panel selection or adjustment takes place, the VSC 150 responds by sending a message to the host. No response is required from the host. The VSC-initiated messages are listed here (underlined).

(C)COPYRIGHT 1999, EXTRON ELECTRONICS, VSC 150, Vx.xx

The VSC 150 displays the copyright message when it first powers on. Vx.xx is the firmware version number.

RECONFIG The VSC 150 sends the Reconfig message when the input source is changed and when changes have been made to one or more of the settings.

VSC error responses

When the VSC 150 receives a valid SIS command, it executes the command and sends a response to the host device. If the VSC 150 is unable to execute the command because the command is invalid or it contains invalid parameters, it returns an error response to the host. The error response codes and their descriptions are as follows:

E10 – Invalid command

E11 – Invalid preset number

E13 – Invalid value (the number is out of range).

Time-out

A delay of 10 or more seconds between command sequence characters causes a time-out. The command operation is stopped, and there is no indication that a time-out occurred.

Using the command/response table

The command/response table on the next page lists valid command ASCII codes, the VSC 150’s responses to the host, a description of the command’s function or the results of executing the command, and an example of each command. Lower case characters are acceptable in the command field only where indicated.

The ASCII to HEX conversion table below is for use with the command/response table.
