Remote Control via Simple Instruction Set (SIS\⤀

The SW8/12 VGA Ars switchers can be controlled via RS-232 using Extron’s Simple Instruction Set (SIS) commands.

The RS-232 port communications protocols are: 9600 baud, 8 data bits, 1 stop bit, no parity, and no flow control. Cable pinouts are shown in the table below.

Only pins 2, 3, and 5 are required. Disconnect all other conductors in the attachment cable for proper operation.

Rules governing SIS commands include:

SIS commands consist of one or more characters per field.

No special characters are required to begin or end a command sequence.

When a command is valid, the switcher executes the command and sends a response to the host device.

All responses from the switcher to the host end with a carriage return and a line feed (CR/LF = ]), which signals the end of a response character string.

A string is one or more characters.

Switcher-initiated (unsolicited\⤀ messages

When a local event, such as a front panel operation or error condition, occurs, the switcher responds by sending a message to the host. Switcher-initiated messages are listed below:

(C)Copyright 2008, Extron Electronics SWy VGA Ars, Vx.xx] The switcher issues the copyright message when it first powers on. y = the number of inputs (8 or 12, depending on the model)

x.xx = the firmware version number
