### 注意安装DMA前必须将游戏机关机并且断开电源，带电拔插DMA会导致DMA被损坏!!!!!
Before installing DMA, the game console must be turned off and the power must be disconnected. Inserting or unplugging DMA with power on can damage the DMA!!!!!
### **优先选择USB3\.0的接口，如果没有就买个type\-c转USB3\.0(蓝色接口)，否则会影响测速的速率**
Prioritize choosing the USB3.0 interface. If not available, buy a Type-C to USB3.0 (blue interface), otherwise it will affect the speed of speed measurement
### **注意:对于带板载开关的DMA设备，开启和关闭必须要在游戏机关机的状态下才能操作，游戏机开机的时候开关DMA，容易造成DMA的损坏!!**
Attention: For DMA devices with onboard switches, turning them on and off must be done while the game console is in operation. Turning on and off DMA when the game console is turned on can easily cause damage to the DMA!! **

#### ①DATA口:背后凸出挡板的Type\-C口，用于与副机进行数据传输，凸出的C口设计可更方便安装数据线，方便拔插和识别。
① DATA port: The Type-C port protruding from the back of the baffle is used for data transmission with the secondary unit. The protruding C-port design makes it easier to install data cables, plug in and identify them

②CFG口:仅用于固件更换或设置板子发出前都已经烧录好固件基本不会使用到它
② CFG port: only used for firmware replacement or setting up the firmware that has been burned before the board is sent out, and it is basically not used
#### ③断电开关:按下开启，松出关闭，必须在电脑关系祖航台下才能操作断电开关。
③ Power off switch: Press to turn on, release to turn off. The power off switch can only be operated under the computer interface.
#### ④电源指示灯:正常情况开机后常亮如果开机后不高请检查断电开关是否被关闭。
④ Power indicator light: Normally, it stays on after turning on. If it is not high after turning on, please check if the power-off switch is turned off.
#### ⑤自检灯:电脑开机后会闪烁几下自检板子是否正常检测正常后自检灯熄灭
⑤ Self check light: After the computer is turned on, it will flash a few times to check if the board is working properly. After checking, the self check light will turn off
#### ⑥状态指示灯:正常情况开机后会闪烁几下然后常亮。如果一直闪烁可能是PCI通道冲突参考故障处理教程
⑥ Status indicator light: Under normal circumstances, it will flash a few times after turning on and then remain on. If it keeps flashing, it may be a PCI channel conflict. Please refer to the troubleshooting tutorial
#### ⑦重置按钮:仅用于工程调试平时使用不要去按它可能会出现一些莫名的问题。
⑦ Reset button: only used for engineering debugging. Do not press it during normal use as it may cause some inexplicable problems
#### ⑧)辅助安装槽:用于辅助安装安装时将板子对准PCIE卡槽后将手指放在辅助安装槽向下按压让板子安装的更稳。
⑧ Auxiliary installation slot: used to assist in installation. Align the board with the PCIE card slot and place your finger on the auxiliary installation slot to press down and make the board installation more stable.
### ⑨可调挡板安装孔:板子挡板固定在机箱上的时候可能会有错位可通讨调节这个孔的固定螺丝的位置来将板固定孔对准!
⑨ Adjustable baffle mounting hole: When fixing the board baffle to the chassis, there may be misalignment. Please adjust the position of the fixing screw of this hole to align the board fixing hole!

### 安装准备 Installation preparation

#### 安装位置 确认安装DMA的卡槽位置，下图显示的这三种卡槽都可以直接安装DMA，通常来说只要能安装的位置，先随机找一个卡槽安装即可。
Confirm the installation position of the DMA card slot. The three card slots shown in the figure below can all be directly used to install DMA. Generally speaking, as long as the installation position is available, a random card slot can be selected for installation first.

## 安装教程Installation Tutorial

#### 1将游戏机关机

#### 2【不带开关的DMA请忽略】对于带开关DMA，先将DMA打开，通常来说按钮的开关按下为开，松出为关!

#### 注意:必须在游戏电脑关机的情况下，才能操作这个开关!不能在开机的状态下操作他!
1. Shut down the game console. 2. [Please ignore DMA without switch] For DMA with switch, first turn on the DMA. Generally speaking, pressing the button switch will turn it on, and releasing it will turn it off!

Attention: This switch can only be operated when the gaming computer is turned off! Cannot operate it while it is turned on!

![](/media/202507//1752655638.6911974.png)

#### 1:将DMA插入游戏电脑的PCIE卡槽，可以选择你方便的卡槽，PCIE X16PCIE X4,PCIE X1均可插入，一定要保证DMA完全插入卡槽内，将DMA板子的缺口对准PCIE卡槽凸起的位置，直接插入到底即可!

1: Insert the DMA into the PCIE slot of the gaming computer. You can choose your convenient slot, PCIE X16, PCIE X4, or PCIE X1. Make sure the DMA is fully inserted into the slot, align the notch of the DMA board with the protruding position of the PCIE slot, and insert it directly to the bottom!

#### 1:将DMA使用螺丝固定在机箱上，可参考显卡的固定方式。
1: Secure the DMA to the chassis using screws, following the instructions for fixing graphics cards.

#### 2:将数据线的一端插入DMA的DATA口。(数据口)
2: Insert one end of the data cable into the DMA DATA port. (Data port)

#### 1:将数据线的另一端插入到副机的USB口，请优先插入到副机的typeC口，或者usb3\.0的口(usb3\.0的usb为蓝色)，只要你的DMA固定好了，确认好之后就可以恢复电脑然后开机正常使用了，(只要板子安装好，开机顺序啥的都无所谓，只要你不是带电插DMA就行。。。)
1: Insert the other end of the data cable into the USB port of the secondary unit. Please prioritize inserting it into the TypeC port or USB 3.0 port of the secondary unit (USB 3.0 is blue). As long as your DMA is fixed and confirmed, you can restore the computer and start it up for normal use. (As long as the board is installed and the boot sequence is correct, as long as you do not plug in the DMA while it is not powered on.)... )

#### 电脑键盘按WIN＋R键 ，输入msinfo32\.exe ，呼出一个列表。列表里，内核DMA保护显示关闭 ，就是能用！！
Press the WIN+R key on the computer keyboard, enter msinfo32 \. exe, and call up a list. In the list, if the kernel DMA protection display is turned off, it can be used!!

#### 正常的示意图大概就是这样 如果显示关闭请搜索自己品牌主板bios如何关闭 “内核DMA保护”
The normal schematic diagram is roughly like this. If it shows' closed ', please search for your own brand motherboard BIOS. How to turn off' kernel DMA protection '
### **注意**:安装DMA之前必须将游戏机关机，并且断开电源，带电拔DMA会导致DMA被损坏!!!!!

优先选择USB3\.0的接口，如果没有就买个type\-C转接USB3\.0(蓝色接口)，否则会影响测速的速率!

注意:对于带板载开关的DMA设备，开启和关闭必须要在游戏机关闭的状态下操作，游戏机开机的时候开关DMA，容易造成DMA损坏!!!

Attention : Before installing DMA, the game console must be turned off and the power must be disconnected. Pulling out DMA with power on can cause damage to the DMA!!!!!

Prioritize choosing the USB3.0 interface. If not available, buy a Type-C adapter for USB3.0 (blue interface), otherwise it will affect the speed of speed measurement!

Attention: For DMA devices with onboard switches, they must be turned on and off while the game console is turned off. Turning on and off DMA when the game console is turned on can easily cause DMA damage!!!
