Need help?Do you have a question about the Mechdyne Corporation TGX and is the answer not in the manual?
The TGX system is a remote desktop protocol designed for power users such as designers, engineers, scientists, and creatives who work with graphic-intensive applications, large data sets, and require high-resolution data visualization. It facilitates remote access to powerful workstations, whether physical, virtual, or cloud-based, across an enterprise. TGX supports workforce mobility, allowing users to connect from various locations like offices, homes, conference rooms, partner sites, or even remote fields. It also enables multi-user collaboration, connecting teams locally or globally with a "like-local" experience to enhance productivity.
The TGX system operates with two main components: a TGX sender and a TGX receiver. The TGX sender is installed on the remote workstation running powerful applications, typically located in an office, data center, or the cloud. The TGX receiver is installed on the user's local device, such as a laptop, desktop computer, or thin client. The sender transmits video and audio to the receiver, while the receiver provides control inputs via keyboard, mouse, or USB devices.
TGX connections are always initiated by the receiver to the sender. The sender passively listens on a default port for connection requests. The receiver must be able to reach the sender via hostname or IP address, which may require both computers to be on the same network, connected via a Virtual Private Network (VPN), or using a third-party Gateway for port forwarding.
TGX offers three methods to initiate a connection:
The TGX Launcher GUI is used to initiate TGX connections. It can be accessed from the desktop icon on Windows (under Applications -> Internet -> Mechdyne TGX on Linux, and Open Finder -> Applications on Mac).
When launching, users can specify:
After clicking Connect, an authentication dialogue prompts for login credentials (Login and Password) to access the remote desktop.
Upon successful connection, the TGX Launcher GUI is replaced by the TGX Receiver GUI, displaying the sender's desktop according to the selected view mode and remote display settings. The Receiver GUI includes a graphical area for the sender's desktop and a Toolbar. Input (keyboard, mouse) is sent to the sender when the mouse is within the graphical area. Moving the mouse outside allows interaction with the local PC. The Toolbar drops down from the top of the screen if not visible.
The Receiver GUI displays information such as the Username, Sender hostname, Sender desktop resolution, current bandwidth, current framerate, and TGX version. In windowed mode, the window can be moved and resized.
If the sender desktop is larger than the TGX Receiver window, the MiniMap becomes visible, illustrating which portion of the sender's desktop is currently displayed. Users can left-click and drag within the MiniMap to select a different region. Right-clicking and dragging moves the MiniMap itself. A toggle button on the Toolbar shows/hides the MiniMap. The MiniMap is unnecessary and hidden in "Scaled to Fit" mode or when resolutions match.
The TGX Receiver supports various view modes:
The TGX toolbar is visible in windowed or maximized modes, and collapses upward in full-screen or multi-screen modes until the mouse is moved to the top of the screen. It displays current bandwidth usage, frame rate, and provides options for USB redirection, view mode, resolution mode, and MiniMap visibility.
The target framerate can be adjusted (24 Hz, 48 Hz default, 60 Hz max). Lower frame rates use less bandwidth but may impact image quality.
The X icon in the upper right corner prompts to Disconnect or Log Out.
TGX supports redirecting USB devices from the receiver to the sender, primarily for Human Interface Device (HID) class devices. This feature requires the USB component to be installed on both sender and receiver. The USB icon on the toolbar is disabled for collaborators.
The USB Selection window lists all USB devices connected to the receiver. Some options may be greyed out based on disabled USB classes in the configuration file.
The first user to log into a TGX sender is the desktop owner. Other users connected to the sender are collaborators. The desktop owner has administrative privileges, including the ability to disconnect collaborators and manage their keyboard/mouse input. TGX supports up to 4 concurrent collaborators (default is 4, but can be increased or disabled by IT).
Collaborator connection requests trigger a pop-up on the sender, requiring the desktop owner to authenticate the collaborator.
The TGX icon in the system tray shows a list of collaborators. The desktop owner can click the mouse icon to deny collaborator keyboard/mouse control or click the X to disconnect them. Hovering over a collaborator's name shows the computer name.
If the network connection between receiver and sender is lost, TGX attempts to reconnect automatically. The receiver video may freeze for up to 30 seconds before the receiver detects the disruption. A semi-transparent gray overlay indicates auto-reconnect mode. If the network is reestablished, video and audio from the sender desktop will automatically become live. User input is required by the user as part of the reconnect. During auto-reconnect, the user may disconnect from the sender by selecting the "X" on the Receiver per standard TGX disconnect process or choose to change window modes. Auto-reconnect is intended for recovery from short duration network interruptions (e.g., VPN restart, network adapter switch). If the VPN goes down, the user must restart the VPN connection manually. If TGX connection goes through a port forwarding gateway, auto-reconnect is only valid for the length of time that the port remains open per the policy of the network administrator.
TGX supports copy/paste of plain text, formatted text, Excel tables, and images. The desktop owner has access to the clipboard of both sender and receiver. Collaborators have one-way copy/paste functionality from receiver to sender.
Audio output from the sender is shared with the receiver(s). A volume control slider is available on the TGX toolbar. If TGX window is minimized, audio is paused until the TGX window is restored. TGX sends audio associated with the sender's default speaker.
The receiver's mouse cursor is over the TGX window, the cursor icon of the sender's mouse will be displayed. The mouse cursor of a collaborator that does not have mouse/keyboard control will be indicated by an X. On Windows, system key combinations like ALT + TAB, Windows key combinations, and menu key combinations are transferred. CTRL+ALT+DELETE, Windows + L, and multi-media keys are not transferred. TGX attempts to match the sender's locale/language to the receiver's. The sender's keyboard layout is automatically set to the default layout identified for that locale/language. This works on Windows-based sender connected to Windows or Mac receiver. This behavior can be disabled via configuration entries.
TGX uses several third-party technologies, including:
