MAKCU setup

The MAKCU sits between your mouse and the game PC. Your movements pass through untouched; when the second PC wants a correction, it sends it over a serial link and the box mixes it into the same stream.

The game PC sees one USB mouse. Nothing is installed there, nothing is hooked, and the game reads HID reports exactly as it would from your hand.

• Your mouse -> the box.
• The box -> the game PC: this is the cable that makes it a mouse.
• The box -> the second PC: this is the cable that carries the commands.

Both cables are USB and both matter. A box connected only to the game PC passes your mouse through and takes no orders; a box connected only to the second PC is a COM port that moves nothing.

In the product menu on the second PC, open Settings > Device and pick Serial as the device type.

• Serial port - leave it on Auto and the loader finds the box itself. Press Rescan ports if you plugged it in after starting. Pick the port by hand only when several serial devices are connected.
• Baud rate - 4000000 for a MAKCU. 115200 is there for the boxes that only speak it; at that rate a fast correction has to wait for the wire, so use it only if your box requires it.

Press Connect. The status line names the port and the rate it opened at.

Take it in order, it is nearly always one of these:

• The second-PC cable is not plugged in, or is a charge-only cable.
• No COM port appears in Device Manager: the box needs its USB serial driver on the second PC.
• Another program already holds the port. A serial port is exclusive - close whatever opened it.
• The wrong baud rate: try the other one before looking anywhere else.

If Connect succeeds and nothing moves in game, the serial half is fine: check that the box is the mouse the game PC is really using, with your mouse plugged into the box.
