FAQ

Q:Vibration controller, amplifier and sensor how to connect?

A:  is mainly composed by the vibration controller, amplifier, shaker table, sensors and a PC. Connect the Drive to the input terminal (IN) of power amplifier, the sensor installed on the top of shaker table or installed with fixture on the shaker table. The information of vibration table and amplifier please refer to the data provided by the manufacturer.


Q:Vibration controller connects with PC via network interface, how to set up the network-related information?

A: There are two ways to connect vibration controller with the PC: The first way is connecting network interface of the controller directly with the PC network interface through the network cable, start the controller hardware and "Ready" light is blue, and it indicates the network is connected. Open the software and click Set Licence icon in the Start Page or select Tools-Set Licence, to open "Set Licence" dialog box. Before leaving factory, the default IP address of the controller is 192.168.1.166, so enter the default IP address-192.168.1.166 in IP column, and then import password file from the installation CD under the Password folder. The password file is named as “Licence_Hardware serial number.dat”. The PC IP address is set to "192.168.1.XX". PC IP cannot be set to "192.168.1.166", which is not set as the vibration controller’s IP. In order to test whether the network connection is normal, run command "Ping 192.168.1.166"under the windows DOS to test whether the vibration controller network is normal. The other connection method is connecting vibration controller with HUB (switch), make the controller become a node in a LAN, but ensure that PC and vibration controller network segment is consistent, namely "192.168.1.xx". Then any one of computers within this LAN can control this controller. When using a wireless router (AP) network, the vibration controller is connected with a router, and then PC can through the wireless network to establish communication with vibration controller.
