The YSC 8K<\/b> is a mouse signal control and passthrough unit built on custom firmware written from scratch<\/b>. It supports the full polling range from 125 to 8000Hz<\/b>and runs two protocols at the same time: the COM serial port<\/b> andthe kmboxnet network protocol<\/b> \u2014 so it works with any DMA<\/b> or AI<\/b> software you use, with no hardware changes.<\/p>\nWhy YSC 8K?<\/b><\/h2>\n
Most control boxes on the market are built on open-source code pieced together from different places, and that shows in signal stability and in how the device appears to the system. YSC 8K<\/b> is different: a custom USB stack<\/b> and low-level firmware written from scratch, with a closed-loop architecture<\/b> that leaks nothing outside it.<\/p>\n
In practice, the signal stays clean and stable<\/b> across the full polling range \u2014 even at 1000Hz \u2014 and high-polling devices run at full capacity with no drops or jitter.<\/p>\n The device doesn't lock you to one rate. You can run any value within the full range, depending on your mouse and setup:<\/p>\n The firmware is written from scratch at a low level, along with a custom USB stack<\/b> instead of relying on off-the-shelf libraries. The architecture is closed-loop<\/b>, meaning the input\/output cycle completes inside the device itself and nothing leaks out.<\/p>\n This also means you can set the mouse serial number<\/b> yourself from the software, so the device appears to the system with the identity you choose.<\/p>\n One of the most important features of the YSC 8K is that it supports both protocols in one device<\/b>, so you pick the connection method that fits your setup:<\/p>\n This means it works with any DMA or AI software<\/b> that supports either protocol, without changing your hardware or buying a second unit.<\/p>\n After the first successful setup, just connect in the same order each time.<\/em><\/p>\n Yes, the device supports the full range from 125 to 8000Hz, and you can choose the right rate for your mouse and setup in the software.<\/p>\n<\/details>\n COM is a direct connection over the serial port and is the simplest to set up, while NET is the kmboxnet protocol over the network and suits dual-PC DMA setups. The device supports both, so you choose what works for you.<\/p>\n<\/details>\n It works with any software that supports the COM protocol or the kmboxnet protocol. Before you buy, tell us which software you use and we'll confirm compatibility.<\/p>\n<\/details>\n Yes, the device supports controller passthrough, and the software also lets you convert controller input into mouse movement.<\/p>\n<\/details>\n In the software you can enter a custom serial number for the device instead of the default one. It's written to the device, which then restarts to appear with the identity you set.<\/p>\n<\/details>\n It spreads mouse movement more smoothly between readings, so motion feels smoother, especially at high polling rates.<\/p>\n<\/details>\n Not necessarily. Over the COM protocol it runs with a direct setup, and over the NET protocol it runs in dual-PC DMA setups with a main PC and a second PC.<\/p>\n<\/details>\n From the Firmware section in the software. There are two options: a v1 update over the serial port for single-MCU units, and a v2 update over CDC for Dual-MCU units.<\/p>\n<\/details>\nSpecifications<\/b><\/h2>\n
