Вы купили устаревшую версию коробочки. Сам разработчик пишет следующее
I’m the box developer, the box refresh rate can reach 40Hz, the USB part of the box we have optimized, One Bulk transfer can transfer 512byte, data transmission is about 24KByte / s, you can catch box usb data from Bus Hound. We know DMX512 only is 250K, according to 40Hz to count the words, 512byte * 40 = 20480Byte = 20KByte / s, <24K, of course, our plugin calculate program data need some time, but for the PC it can be negligible, So please believe this box without any delay. Our plugin the only problem is for sunlite and daslight, because the inside of the decoded data takes a lot of time, there will maybe not smooth, other software is very smooth, I have other work to do, now very busy, so do not fix this bug, I think I can find some way to fix this problem. This box is excellent software technology, not hardware technology, we need to keep those crack any dmx software, the cost of the crack software not the hardware. although we promise free upgrade for 2 years, but in fact the old SD512 boxes has free upgrade for 4 years now.
This Box History: HD512 USB-DMX512 Box (2016-03-17) To Support Win8/10, Update hardware for Auto Driver.
