Software:

Client network configuration

The default IP address of the processor is 169.254.10.227, and the subnet mask is 255.255.0.0. Please ensure that the IP address of the client host is in the same network segment as the processor, so that the client software can connect with the processor normally. (Note: Client software can modify the IP address of the processor after searching for the device. )

Download software

The installation software program of this machine is downloaded by accessing the processor of the same network segment in the LAN; Access the processor by entering the IP address of the device in the address bar of IE browser, find the download link and download the installation software locally to complete the installation; The factory default IP address of the equipment is 169.254.10.227, and the subnet mask is 255.255.0.0. Please add the address of this network segment to the PC first, so that the equipment can be connected normally. After the device is started, use the browser to access the address "http://169.254.10.227/".

Software login

After the client software is installed, open the software, click the device list, and view the IP list of the devices currently on the network. Click the network connection of the device you want to connect to, and then you can connect the device for software debugging. Please check the help documentation for more details (see Software Help Options).

Common troubleshooting

1. network connection failure: network connection failure is usually caused by different equipment network segments. if the LAN is different from the processor network segment, you can open the software through PC, click modify IP, and change the processor network segment to be consistent with the LAN, and then click network connection.

2. Current sound is output: Please check whether the processor is grounded well first, which usually requires the grounding screw on the left side of the back panel of the chassis to be connected with the metal casing such as cabinet through metal wires. If the problem still exists, please check the wiring of the input device. If the input device is unbalanced (two wires), please connect the "+"and "G" of the processor input interface.
