3 HDMI Wall Plate with Audio Extraction 1. Windows Software Installation 1.1. General The VSA-HA-DP graphical user interface (GUI) is Windows software used to configure advanced settings of the VSA-HA-DP wall plate. Use of the software requires USB connection of the PC to the wall plate. For convenience A USB cable is provided with each wall plate. The GUI can be used to monitor and configure several wall plates simultaneously. So for PC's that have multiple USB ports or with the use of external USB hubs, it is possible to use the same GUI and address each wall plate individually Installation Prerequisites A PC with Windows XP OS or later USB port Microsoft.NET Framework 2.0 or later (most recent OS including Windows 7 and 8 typically include this and no action is required). If.NET Framework 2.0 or later is not installed on your PC, the Microsoft website has free downloads available Software Installation If an earlier version of this particular software was previously installed, UNINSTALL the program first from either the Add/Remove Programs section of the control panel or by running the previous installation SETUP.EXE and selecting remove application. Install the software by executing the SETUP.EXE program from the installation source directory Accept the default settings, but if you want to specify a particular installation directory other than the default, you may do so. Once the VSA-HA-DP software installation has completed, either click the desktop icon or navigate the Start Menu to Start Programs Hall Research VSA-HA-DP Audio Extractor 1

4 VSA-HA-DP Software Guide 2. Using the Software 2.1. General The VSA-HA-DP has no front panel switches, configuration changes are made via the Software GUI installed on a compatible PC. The GUI software can be used to manage the EDID routing mode of the device such as "pass-through" or "emulate", import/export EDID files to/from the device, Set the audio descriptors in the EDID for (two channel or multi-channel), mute the extracted audio, remove the audio from the HDMI video output, cycle HPD to the source, and more. The GUI can also be used to monitor status of several pertinent parameters such as detecting the input video and audio states and types USB Device Detection The VSA-HA-DP software automatically configures the USB port after connection to the wall plate (using standard Windows USB drivers) and does not require any special USB drivers to be installed. Once connected to a USB port, the Windows system will detect and use the appropriate USB driver. The first time you connect the wall plate to the PC, you may experience a short delay and a windows notification pop-up message may be shown. This detection and driver installation only occurs when the VSA-HA-DP is connected to the PC for the first time. Afterwards, reconnected devices automatically configure themselves with no delay or message. The software scans the VSA-HA-DP settings continuously in real time, so all changes are immediately reflected on the screen If no VSA-HA-DP device is attached to the system, the on-screen fields are disabled (grayed out) Only one instance of the program can run at a time. Executing the application more than once will result in an error message. 2

5 2.3. Tool Bar Menu Restore device settings from file Used to select previously saved files Save device settings to a file HDMI Wall Plate with Audio Extraction Saves the current configuration file to any location on the PC. Factory Defaults Restore the device to factory default settings. The user must confirm the action. Import EDID Import an EDID (256-byte binary or XML file) into the unit. Export EDID Save the current EDID as a 256-byte binary file This file can be edited using third party software and reloaded using the 'Import EDID' tool selection. Write EDID (use with caution) Writes the current 256-byte EDID to the sink device currently connected to the output. The user must confirm the action. This command tries to alter the EDID of whatever is connected to the HDMI output (of the VSA receiver). Most displays such as LCDs or projectors may have a Read-Only EDID, in which case this command will not able to alter the EDID in the display. The user must confirm the action and take all necessary precautions to prevent loss of data. Hall Research is not responsible for any damage that may occur from the user attempting to modify the EDID of the sink device. Firmware Update Allows field upgrade of the firmware in the VSA-HA-DP. If your unit is not upgradable, then this function will be disabled. Exits the application Displays screen with software versions, website link, legal disclaimer and copyright information 3

6 VSA-HA-DP Software Guide 2.4. Device Name Assigns a descriptive name to the VSA-HA-DP device that is a maximum 8 characters long. This information is stored in the wall plate. Assigning unique Device Names to each wall plate can be useful to positively identify each wall plate. This can prove handy if you are going to upload different configurations for each device, or if you intend to connect multiple devices simultaneously to a PC and use the software to control several at once. The FACTORY DEFAULT name is USBDEVHR. You can change the device name only when just one VSA-HA-DP is connected to the PC Status Bar The bottom bar of the screen shows the USB connection status as follows: This indicates the software has not detected any VSA-HA- DP devices and is searching the USB ports for devices. Controls are disabled until a valid VSA-HA-DP device is attached and properly identified by the software. PC. Shows the number of VSA-HA-DP devices that are connected to the 2.6. Controls VIDEO EDID The VSA-HA-DP creates an EDID table that the source connected to the input can read. You can control how the parts of the EDID table that pertain to video capabilities are constructed. Clicking these controls selects to either PASS-THRU or EMULATE the EDID. PASS-THRU uses the EDID from the Sink device (typically the actual display connected to the output), while EMULATE uses the internal EDID saved in the VSA-HA-DP. PASS-THRU is the FACTORY DEFAULT setting. Learn EDID Clicking this control will extract the EDID from device connected to the output connector and save it in the unit. The user must confirm the action. 4

7 AUDIO EDID HDMI Wall Plate with Audio Extraction Similar to Video EDID, you can control how the parts of the EDID table that pertain to audio capabilities are constructed. Clicking these controls selects either PASS-THRU, 2 CHN or MULTI modes 2 CHN EDID from SINK is set for 2 channel LPCM audio with 2 speakers. MULTI EDID from SINK is set for LPCM, DTS and Dolby audio with multiple speakers. PASS-THRU EDID from SINK is used 2-Channel is the FACTORY DEFAULT setting. Since the VSA-51 has a stereo 2-channel audio amplifier, it is best to have the EDID set for two channel regardless of what is connected downstream. EDID Routing Modes Mute Audio On HDMI output Clicking this control removes the audio portion from the HDMI video output (on the VSA- 51 HDMI output connector). You can use this command to make sure no audio comes out of the display's built-in speakers. FACTORY DEFAULT is not muted. Misc Cycle HPD Clicking this control sends causes a 0.5 second pulse on the Hot Plug Detect signal that is sent to the video source. So basically the source will see an unplug and a re-plug. It has the same effect of unplugging the HDMI input cable and plugging it back in. This forces the source to re-initialize its HDMI video output connection (read EDID, and implement HDCP if required) This indicator is filled green when the source is connected. 5

8 VSA-HA-DP Software Guide Disable DDC Enabling this control will turn off the DDC communication with the SOURCE device. The SOURCE will receive no response from any HDCP or EDID requests. This effectively disables the SOURCE from displaying HDCP content and most PC's will not output any video if they can't read the EDID. FACTORY DEFAULT is not enabled (HDCP and EDID are enabled) Status Video Input No Video Indicates the system is not receiving an INPUT video signal. HDCP On Indicates video received has HDCP Encryption enabled. HDCP Off Indicates video received has HDCP Encryption disabled. Audio Input No Audio Indicates no audio received (DVI mode) Multi-Channel Indicates HDMI audio received is not LPCM format. 2 Chn Indicates HDMI audio received is LPCM format. Video Output Connected or Disconnected Indicates the state of the device connected to the VSA-HA-DP OUTPUT EDID Data Display The data shown in the EDID table is continuously and updated on the screen. Also the software ensures that the checksums for each block is valid. 6

9 HDMI Wall Plate with Audio Extraction When an invalid checksum is detected, that byte (at the end of 128 bytes) is highlighted in RED. This helps identify invalid EDID checksum values that can cause connectivity problems. If you perform an action that affects the EDID, it is possible for the checksum to momentarily show RED until the complete EDID has been updated on the screen. You cannot LEARN an EDID that has an invalid checksum! The GUI interface software WILL let you IMPORT EDID s that contain invalid checksum data for testing purposes Note about EDID Mixing At power up, the default EDID stored within the device is loaded. This could be either the factory default or a Learned EDID. If a functioning and valid SINK device is connected to the VSA-HA-DP Output connector AND the VIDEO mode is set to PASS-THRU, the EDID from the SINK will be read and loaded into memory. If the SINK EDID read is a simple 128 byte EDID (like a VGA monitor), a CEA-861 extension block (2nd 128 bytes) will be added to the EDID with a default native resolution of 480p and with LPCM 2 channel audio. If the SINK is disconnected from the VSA-HA-DP connector, the internally saved EDID will be presented to the SOURCE mixed according to the AUDIO settings. Each time the VIDEO or AUDIO EDID GUI controls are pressed, the EDID presented to the SOURCE is would be as shown in the following table: 7

(The VSA-HA-DP device does not understand any CEC commands). For example: SINK EDID has CEC address of EDID given to source will show the VSA-HA-DP as CEC address and the display still with its original CEC address of
