Hardware installation: VideoGhost Pro/Max
Posted: Jun 18, 2020
Connecting the hardware is quick and easy, no software or drivers are required. First locate the source of the video signal, such as the output of the graphics card, or the TV output.
Connect the VideoGhost Pro/Max to the video source, and then connect the output device (TV or monitor) to the other end of the VideoGhost Pro/Max.Finally, connect the USB connector to a free USB port.
The USB port is used for powering the device, and for communication with the host in either flash drive mode or Virtual COM mode. If the device is in Capture mode (Configuration 1 or Configuration 4), then a +5V DC USB power supply may be used instead.
In case of the VideoGhost Max, an auxiliary RS-232 device may be connected to the DB-9 cable. Refer to section COM commands for instructions how to control the VideoGhost Max from an external device.
The VideoGhost Pro/Max is now ready to capture screenshots. If this is the first time the device is being used, it will default to Configuration 1 (VideoGhost Pro) or Configuration 4 (VideoGhost Max), meaning it will not show up as a USB device. Press the external push-button for 3 seconds to switch to flash drive mode, and configure the device through the file CONFIG.TXT (see section Device setup).
Device setup If your VideoGhost Pro/Max is already configured to operate in Virtual COM mode (Configurations 3 or 5), further configuration may be done using the PC application VideoGhost Control. Simply install VideoGhost Control and use it to connect and configure the device (see section Virtual COM mode).
If your VideoGhost Pro/Max is configured to operate in Capture mode (Configurations 1 or 4) or flash drive mode (Configuration 2), it may be configured through the file CONFIG.TXT, placed in the flash drive root folder. This is the case for newly delivered devices. First, press the external push-button for 3 seconds to switch to flash drive mode (Configuration 2). Then use any text editor to create or open the file CONFIG.TXT.
Put the following line in the file, if you want to use the VideoGhost Pro/Max in Virtual COM mode (Configurations 3 or 5):
UsbMode=Com
If you want to use the device in flash drive mode (Configuration 2) or simply capture images without using USB (Configurations 1 or 4), put the following line in CONFIG.TXT:
UsbMode=Flash
f you don’t need the internal JPEG capture timer, continue editing CONFIG.TXT by placing the following line in it:DisableLogging=Yes
If you want to use the internal JPEG capture timer in any of the modes, place the following lines in CONFIG.TXT and modify the values accordingly:DisableLogging=NoInterval=300Resize=50Timestamping=Image
DisableLogging allows disabling JPEG logging. Allowed values are Yes (logging disabled) and No (logging enabled). Default value is No.
Interval sets number of seconds between successive screenshots. Please note that compressing and saving an image takes several seconds (depending on the image size and quality), so this may become the limiting factor for low values of Interval. Default value is 300.
Resize sets the resizing factor for storing screenshots. Allowed values are No (no resizing), Auto (automatic resizing factor based on image size), 75 (75%), 67 (67%), 50 (50%), 33 (33%), and 25 (25%). Default value is No.
Timestamping configures the built-in time- and date-stamping module. Allowed values are Yes (timestamping active, but limited to updating the modification time and date of JPEG files), Image (timestamps burned into JPEG image content), and No (timestamping disabled). Default is Image.
When finished editing CONFIG.TXT, save the file in the root folder of the flash drive, and safely remove the drive. The new configuration will be loaded on next power-up.
The configuration file CONFIG.TXT may contain several parameters, fully configuring how the VideoGhost Pro/Max operates.
Virtual COM modeThe primary purpose of Virtual COM mode (Configurations 3 or 5) is to perform on-demand image capture, access recorded JPEG images, and configure the device.
Before connecting the device, make sure you have installed the VideoGhost Keylogger Control application, delivered with your device.
VideoGhost Control is also available with source code in C# on the CD-ROM delivered with the device.
Installing VideoGhost Control is a straightforward process, simply follow the wizard’s dialog windows.
Next, connect the VideoGhost Pro/Max to a USB port. When connected to a USB port, the VideoGhost Pro/Max will attempt to enumerate as a Virtual COM device (Communications Device Class). Most operating systems contain built-in drivers. Some operating systems, such as Windows XP/Vista/7/8, will require confirming the driver’s publisher (select Install the driver software anyway).
If the operating system has any difficulties finding the correct INF file, select it manually from the Driver folder in the VideoGhost Control installfolder. This is usually:
C:\Program Files\VideoGhost Control\Driver\
orC:\Program Files (x86)\VideoGhost Control\Driver\
After successfully installing the device driver, launch VideoGhost Control. Connect to the VideoGhost Pro/Max using the first icon in the toolbar. This will scan all COM ports, searching for a compatible VideoGhost device.
Once connected, the software will display a list of images in the list on the left panel. The panel has two sections:
- Local ImagesThis section will contain a list of BMP images captured using VideoGhost Control (Snapshot feature). The images are stored on the computer’s hard drive. The folder will default to My Pictures\VideoGhost Control, however can be configured in the application’s options. Clicking on an image from the list will display the image in the right panel.
- Remote ImagesThis section will contain a list of JPEG images archived on the VideoGhost’s internal flash drive. Clicking on an image from the list will initiate a file transfer from the device, and then the image will be displayed in the right panel.
One of the primary features of VideoGhost Control is taking a snapshot. This can be initialized using the Device->Take a Snapshot option, by clicking the second icon in the toolbar, or pressing CTRL+T. The device will capture an image from the DVI/HDMI/VGA interface, and transfer it through Virtual COM to VideoGhost Control. The image will then be immediately displayed, archived on the computer’s hard drive, and listed in the Local Images section.
