How to set up a KMBox Net for DMA cheats
When you need a KMBox, how to wire a KMBox Net, and how to prove the ethernet path before you touch the game software.

When you need this device
KMBox Net is an input device: the second PC sends mouse and keyboard commands through it to the gaming PC. You only need one for aim or recoil features that your software actually offers, because radar and ESP on a second screen work without it. Wait until the product page says a feature uses an input device before you buy one.
What you need
For a first test you need the following.
- KMBox Net
- An ethernet cable, Cat5e or better, kept short for the first test
- A spare USB mouse and keyboard plugged into the KMBox
- Your gaming mouse and keyboard stay on the gaming PC unless the product instructions say otherwise
- The WCH USB NIC driver for the KMBox network adapter, from the official Downloads or Discord resource listed on this site
Info
How to wire it
Plug the spare mouse and keyboard into the KMBox USB host ports and connect the KMBox USB output to the gaming PC. Run ethernet from the KMBox straight to the second PC for the lowest latency, or through a router if you accept the extra hop. Power the KMBox the way its manual describes before you start adjusting software settings.
Set the network addresses
Stock KMBox Net units usually sit at 192.168.2.188, so a direct link needs a static address on the second PC's adapter in the same subnet, for example 192.168.2.100 with mask 255.255.255.0. If those addresses are already used on your network, pick a free pair and set both ends to match, because an IP conflict looks exactly like a dead device.
Connect from the second PC
Install the official KMBox software on the second PC and run it as Administrator. Enter the KMBox address, connect and move the spare mouse, and the cursor should move on the gaming PC. Only after that test passes should you enter the same address in the game software.
- Install the WCH USB NIC driver if the adapter is not already present
- Give the second PC's ethernet adapter an address on the KMBox subnet
- Open the KMBox tool as Administrator
- Connect to the device address
- Check that ordinary cursor movement reaches the gaming PC
Tip
Direct cable or through a router
A direct ethernet cable between the KMBox and the second PC is the usual low-latency setup. Going through a router is fine for a first bring-up, but it adds delay and DHCP surprises, so move to a short, reliable cable afterwards and never start on Wi-Fi.
Warning
What usually goes wrong
The common faults are a wrong subnet, leftover DHCP settings on the adapter, the spare mouse still plugged into the gaming PC, or game software pointed at a different IP from the one that just passed in the KMBox tool. Check each of these as a separate problem.
What to send support
Send a photo of the wiring, the IP addresses on the KMBox and on the second PC, whether the official tool already moves the cursor, and your order ID. If the tool works but the game software does not, say so clearly, because it tells support the hardware is fine and the problem is the integration.
