V-SWITCH quad CHANGES IN FIRMWARE V1.30 This is a preliminary document describing the function of the new features in firmware version 1.30. This document complements the manual for V1.20 ("V-SWITCH - Manual - V120 engl.pdf"). 1. Multiple Safe Video Modes 2. Mouse / Keyboard Control with Open OSD / Hotmouse 3. Remote Control Using ConfDev Tool 4. New OSD Menus 4.1. SYSTEM -> CONTROL 4.2. COMPUTER -> CHANGE EDID/DDC 5. New Video Modes 1. Multiple Safe Video Modes V-Switch quad now offers multiple safe video modes for displays that do not support VGA (640x480) resultions. By holding buttons 1 and 2, you can switch to a safe mode. The first safe mode is indicated by LED 1 lit in green. Repeatingly pressing and holding buttos 1 and 2 will cycle through the available safe modes (SVA - 800x600, XGA - 1024x768 and UXGA - 1600x1200), indicated by LEDs nos. 2 to 4. 2. Mouse Control with Open OSD When the OSD is open, the active computer can still be controlled using the mouse. When the Hotmouse Cursor is activated, or the Hotmouse Menu is open, the active Computer can still be controlled using the keyboard. 3. Remote Control Using ConfDev Tool With the ConfDev tool (included on the CD), the V-Switch quad's OSD can be opened from a computer connected with a serial cable. Use the update cable included with the V-Switch quad. In ConfDev, use File->Settings to choose the correct COM Port, then click the green arrow toolbar button (or use Device->Configure) to connect to the V-Switch quad. 4. New OSD Menus 4.1. SYSTEM -> CONTROL Using an the XML-based DCP (Device Control Protocol), the V-Switch quad can be controlled remotely using a serial cable. For a description of the DCP, please refer to the document "DCP-XML Description.doc" included on the CD. The Menu SYSTEM->CONTROL offers three DCP modes: off - off Control - used for controlling a single device Synchronize - used the synchronize a chain of V-Switch quad devices Control In this mode, the V-Switch quad accepts settings sent using DCP, and echoes back the current settings after processing a DCP command. Synchronize In this mode, the V-Switch quad sends all settings changes as DCP via the serial port, allowing a chain of V-Switch quad devices to be controlled synchronously. To set up, you will need a special serial cable, connecting the Tx - Pin of one VSQ to the Rx pin of the next VSQ, and so on to create the chain. Do not connect the last device in the chain to the first on (do not make a circle). Optionally, you may connect a computer to the first device in the chain to control it as in Control mode (with the exception that you can not connect the computer's Rx pin to the first VSQ - you can, however connect the last VSQ's Tx pin to the computer's Rx pin, to receive settings changes). A device in Synchronize mode transmits all settings upon startup, to initially synchronize the settings. To start a synchronized chain of V-Switch quad devices, switch on the devices in succession, starting from the END of the chain. Then, switch on the next-to-last device, and so on. Do likewise when first enabling Synchronize mode. COM Port Settings: Baud Rate: 57600 Data Bits: 8 Parity: none Stop Bits: 1 Flow Control: none 4.2. COMPUTER -> CHANGE EDID/DDC The new firmware offers the possibility to customize the EDID (Extended Display Identification Data) programmed into the four input ports. Each in put port may be programmed seperately. To program, use the following procedure. Recommendation: If you use the ConfDev tool, you will be able to see the OSD throughout the process, including steps e-f, where you will have to disconnect the V-Switch quad's video output from the monitor. a. Enter the Menu COMPUTER -> CHANGE EDID/DDC. b. Choose two video modes that you want to program into the EDID. c. Choose whether the V-Switch quad should identify itself as an analog or digital device. Normally, choose digital. If your computer is connected to the V-Switch quad with its analog output and you are experiencing problems (e.g. blank display), choosing analog here may solve the problem. d. Select WRITE. e. Connect the V-Switch quad's video output to the input port you want to program.. f. Press Enter/Select twice. g. Reconnect the video output to a monitor. h. The OSD should now read "Program EDID: successful" 5. New Video Modes HDTVp 1280 x 720 @ 50Hz, 60Hz HDTVp 1280 x 720 @ 24Hz, 50Hz, 60Hz HDTV modes are progressive (non-interlaced) only WXGA 1366 x 768 @ 60Hz UXGA 1600 x 1200 @ 50Hz WUXGA 1920 x 1200 @ 50Hz reduced pixel clock modes UXGAr 1600 x 1200 @ 50Hz (120MHz pixel clock) UXGAr 1600 x 1200 @ 60Hz (144MHz pixel clock) All new modes, as well as the following existing modes can be input with reduced refresh rates as low as 22Hz. These reduced refresh rate modes are limited to digital input only.
