Remote Control

The SW6 VGA Audio switcher’s rear panel Remote connector (figure 3-1) can be connected to the serial port output of a host device, such as a computer or control system, to an Extron IR 102 Kit Universal Remote Control, OR to a remote contact closure device. Remote coontrol of the switcher is via Extron’s Simple Instruction Set (SIS™), Extron’s Windows®-based control program, the IR 102 Kit, or a contact closure device.

Figure 3-1 — Remote connector pinout

The RS-232 protocol of the rear panel Remote connector is 9600 baud, 1 stop bit, no parity, and no flow control. The connector has the pin assignments shown in figure 3-1.

For RS-232 and IR control, use a control cable with only pins 2, 3, and 5 connected. To accomplish this, either cut the wires to the other pins in hard-shelled connectors, or remove the unneeded pins from molded plugs.

For contact closure, use a control cable with pins 2 and 3 NOT connected. To accomplish this, either cut the wires to these pins in hard-shelled connectors or remove these pins from molded plugs.

Host-to-switcher communications

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 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 the 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. The switcher-initiated messages are listed below:

The switcher issues the copyright message when it first powers on. Vx.xx is the firmware version number.

Cn]

The switcher issues the Cn message when a front panel input selection operation occurs and immediately following the copyright message. n is the input number.

Reconfig]

The switcher initiates this message when there is a change in an

.audio gain setting.

Error responses

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

E01 Invalid input channel number (out of range)

E06 Invalid input channel change (auto switch mode active)

E09 Invalid function (mode) parameter

E10 Invalid command

E13 Invalid value (out of range).

Timeout

Pauses of 10 seconds or longer between command ASCII characters result in a timeout. The command operation is aborted with no other indication.
