Audio output connections The switcher have two 3.5mm 5-pole captive screw audio output ports. The Fixed port delivers a fixed volume, stereo balanced/unbalanced audio output. The Variable port delivers a variable volume, stereo balanced/unbalanced audio output. The volume range is 0 (-84 dB) through 100 (0 dB). The default volume setting is 100 (0 dB). Volume is controllable only via the RS-232 port.
Installation and Operation, cont’d VSW I AAP connection The VSW I AAP (part #70-529-11, -21, -51) is an optional Architectural Adapter Plate that provides remote input connection and selection for some Extron switchers. The VSW I AAP can be connected to the SW8/12 VGA Ars input ports for input selection control. The VSW I AAP is equipped with a “Show Me” button for input selection, a female 15-pin HD VGA connector, and a 3.5 mm stereo audio jack.
6. Connect a VGA cable from an input device to the Computer input port on the VSW I AAP. 7. Apply power to the display device, the switcher, and then the input source. 8. Press the “Show Me” button on the VSW I AAP. The video input to the VSW I AAP is directed to the switcher’s output ports and should now be present on the display device. 9. If desired, connect an audio input to the VSW I AAP, and use the “Show Me“ button to test its output to the system’s audio output device.
Installation and Operation, cont’d IR 102 remote control connection The SW8/12 VGA Ars switcher can be controlled via its RS-232 port and an infrared signal. The IR 102 Remote Control Kit (part #70-224-01) is required. To connect an IR 102 Receiver to an SW8/12 VGA Ars switcher: 1. Connect a 9-pin serial cable, with only conductors 2, 3, and 5 connected, to the RS-232 output port on the IR 102 receiver. 2. Connect the serial cable to the RS-232 port on the switcher’s rear panel.

SW8/12 VGA Ars 3 Chapter Three Control Remote control via Simple Instruction Set (SIS™) Updating Firmware
Control 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.
Error responses When the switcher receives a valid command, it executes the command and sends a response to the host device. If the unit is unable to execute the command because the command contains invalid parameters, it returns an error response to the host.
