1 Product Overview DESCRIPTION: The IN31608 Presentation Switcher combines the easy operation and serial control capabilities of a projector switcher with the flexibility of a matrix switcher. Featuring RGBHV + stereo audio matrix switching, 350 MHz bandwidth and two switching modes, the IN31608 is ideal for permanent installations, rentals, complex staging operations and any other display system requiring a high performance, economical presentation switcher.
2 Switching - Connecting Inputs and Outputs (Front Panel) DIRECT MODE Press the button of the input you desire and the signal will automatically be sent to the appropriate output(s). Video, sync and audio are always routed together as a group (see DIRECT MODE SETUP on page 7 for more details.) That input LED will light as well as any of the selected output LEDs. To disconnect all outputs press the Blank Button.
3 SWITCHING EVENT ORDER The following procedure describes the precise order of events each time a switch is made. 1) Wait for: a) Next sync signal (genlock operation / vertical interval switching only), or b) Timer time-out, whichever comes first. 2) If video included in switch group (video always included in switch group for Direct Mode): a) Update video array for particular in-to-out channel. b) Set video switch to array but don’t update yet.
4 RGB delay prevents the display device from showing re-sizing and other spurious on-screen effects that often occur while the display is adjusting to the new signal. Audio In Matrix Mode, the audio for the selected input is routed to the selected output. Note that the video, audio, and sync may be switched independently in Matrix Mode. In Direct Mode the audio of the selected input is sent to the selected output(s).
5 INPUT VOLUME If the Mute Button is depressed simultaneously with the Volume Up / Down Button, the input volume for the currently selected input is affected instead of the output volume. In this case the Input Button’s LED flashes until the maximum / minimum input volume is reached. By adjusting input levels, the levels of all the various input sources can be equalized. This is important so the volume level does not increase / decrease dramatically when switching between inputs.

7 Direct Mode Setup (Front Panel) In the Direct Mode, inputs are assigned to a designated output and automatically routed to the output(s) when selected. This section describes the procedure to assign inputs to outputs via the front panel. 1. Enter the Direct Mode Setup with the appropriate power on setting (see Power On Settings section on page 8 for more details.) Once in the Direct Mode Setup, all output LEDs and the direct LED will flash. To exit the setup with no changes, press the Save Button. 2.
8 Power On Settings The IN31608 utilizes Power On settings to access certain parameters of the unit. To access a Power On adjustment, you must depress a specific button while turning the unit’s power switch to ON. If power is already on, the user can hold down the indicated button and switch the power off and then back on.
9 FRONT PANEL TEST MODE (MODE) Hold down the Switching Mode Button while turning on the unit. The Front Panel Test Mode continually polls the front panel switches. When a button closure is detected, the associated LED is turned on. If the button remains closed the LED begins to flash. The Volume Down Button controls all output LEDs simultaneously. The Switching Mode Button controls the five associated LEDs in sequence. To exit the Front Panel Test Mode turn the power off and then back on.
10 Projector Control Port The projector control port can be used to control a piece of equipment via RS-232, RS-422 or RS-485. The communication parameters of the port are set via the serial [PCPPxx] commands. The projector codes are stored in non-volatile memory. This feature is enabled / disabled by the [PCP…] command. When the IN31608 performs certain actions, a code is transmitted through the projector control port.
11 A successful response from the IN31608 is issued after execution of the command Except for the ACI and CMDCD commands. The response to the ACI command is sent at the existing baud rate, and then the baud rate is changed. The response to the CMDCD command is sent with the existing command code and then the command code is changed. COMMAND CODE DEFINITIONS The IN31608 can recognize one of four sets of leading and ending characters, also called the command codes. These are: [ ] { } ( ) < >.
