¶ Installation and Configuration Instructions
¶ Critical Safety Guidelines
-
Ensure Complete Power Down of the Main PC
Prior to installing the Direct Memory Access (DMA) device, it is imperative to completely power off the main PC and disconnect its power source. Attempting to insert or remove the DMA device while the power is active may result in damage to the DMA board.
¶ Regarding the Kill Switch
- For DMA devices equipped with an integrated switch, it is essential to activate or deactivate the switch only when the PC is powered off. Manipulating the switch while the PC is operational can lead to potential damage to the DMA device.
¶ USB Connection Best Practices
-
Optimal USB Connection
It is recommended to prioritize the utilization of a USB 3.0 port, preferably a USB Type-C connection. In the absence of a USB 3.0 port, consider acquiring a Type-C to USB 3.0 (blue port) adapter. Failure to adhere to this recommendation may impact the accuracy of speed measurements.
¶ Prerequisite Software Libraries
-
Essential Software Libraries
- Visual C++ Runtime All-in-One Pack - Obtainable from TechPowerUp
- DirectX Runtime - Available for download from Microsoft
¶ Preparation Steps
- Install the DMA board into the designated PCIe slots, as illustrated in the accompanying image.
- Supported PCIe Configurations: x16, x4, and x1.
- Secure the DMA device to the casing using appropriate screws, akin to the installation of a graphics card.
- Establish a connection between the DMA (Data Port) and the secondary PC, preferably utilizing a USB 3.1 interface.
- Provided the DMA device is securely fastened, the data cable may be connected or disconnected at any time, irrespective of the computer's power state. However, when inserting or removing the DMA device itself, it is imperative to power off the gaming computer.
¶ Driver Installation
Important: DMA boards use different USB chips that require specific drivers:
- For boards with CH341 chip - follow the installation steps on this page
- For boards with Quad RS232-HS chip - you'll need to use the Zadig tool. Please refer to our Zadig Installation Guide for instructions
If you're unsure which chip your board uses, check the board documentation or contact support.
Note: The instructions below are for CH341-based boards only. There are two methods for installation...
¶ Method 1: Recommended Automated Installation
- Download the automated installer: CH341PAR.zip
- Extract the downloaded file on your secondary machine
-
Important: Before proceeding, ensure:
- The DMA card is properly connected to both computers
- The DMA card is powered on
- If your DMA card has a kill switch, make sure it is turned OFF
- Run SETUP.exe from the extracted files
- Click "Install" and wait for the installation to complete
¶ Method 2: Alternative Manual Installation
Only follow these steps if the automated installation method doesn't work for your setup.
- Download the DMA Driver: DRIVER
- Extract the downloaded driver directly to the desktop
-
Important: Before proceeding, ensure:
- The DMA card is properly connected to both computers
- The DMA card is powered on
- If your DMA card has a kill switch, make sure it is turned OFF
- Access the "Device Manager" by right-clicking on the "Start" icon located in the lower-left corner of the screen
- Locate the "FTDI SuperSpeed-FIFO Bridge" icon (may have an exclamation mark) and right-click on it
- Select "Update driver", followed by "Browse my computer for driver software". Click "Browse", navigate to the driver folder extracted to the desktop, and proceed with the installation by clicking "OK"
Verification Steps:
- Upon completion, verify the driver's presence in the device list. Note that some computers may install the driver automatically.
- In Device Manager, expand "Universal Serial Bus controllers" and confirm the presence of "FTDI FT601 USB 3.0 Bridge Device"
¶ Post-Installation Verification
-
Upon confirming the successful installation of the DMA device, the indicator light on the DMA should illuminate upon powering on the computer, signifying proper power supply and functionality. In the event that the light fails to activate, please disconnect the DMA device and reinsert it after powering off and disconnecting the power supply of the primary PC.
-
DMA Testing Protocol
All testing procedures for the DMA device must be conducted on the secondary computer. Download the requisite driver and test files exclusively to the secondary computer—under no circumstances should they be downloaded or installed on the main PC.
¶ Important Considerations
-
Avoid Utilizing USB Extenders or Docking Stations
In the event that the secondary computer lacks an adequate number of USB ports, refrain from connecting the data cable to a docking station or USB extender. Such connections may impede the radar computer's ability to recognize the DMA data cable driver. It is strongly advised to directly connect the data cable to a USB port on the secondary computer for testing purposes.
