Hello,mustafa.Please check the USB interface, the specific operation is as follows, please check whether the two pins on the PC-USB on the board are straight.Please connect the power first ，and then use a universal ammeter to measure whether the voltage of the two is about 1.5V. In addition, I will also attach the latest RDworks download link: [https://cloudray2021.oss-us-west-1.aliyuncs.com/Product%20information/Software%26Board/RuiDa6445/RDWorksV8Setup8.01.54-20210513.rar](https://cloudray2021.oss-us-west-1.aliyuncs.com/Product%20information/Software%26Board/RuiDa6445/RDWorksV8Setup8.01.54-20210513.rar) ---

Hello,mustafa.Based on your follow-up response, I have the following suggestions. 1. Is the RDWorks I sent you installed properly? If it is not installed, please install it. 2. If RDworks is installed well, and there are still problems, I suggest you change the communication mode to RJ45 port, and set the IP to any of 192.168.1.1-49, not higher than 50. 3. According to the previous two steps, if it still doesn’t work, please upgrade the firmware version.[firmware version.zip](https://forum.cloudray.com/uploads/short-url/m6VLYlfbRrL5TNeKVwBW5QdYyuP.zip) (1.5 MB) 4. It doesn’t work according to the above, please replace your board. ---

HI,mustafa.Please decompress the compressed file I attached completely, put it into a USB flash drive, connect the board with the USB flash drive, then turn on the monitor and find the file to upgrade.(Please open the RDworks software, click Settings, click System Settings, then click Motherboard Information, find the files in the U disk and upgrade the firmware） ---
