Multiple hardware protectionEFT-IEC61000-4-4-Level3(+-2kv)
Surge-IEC61000-4-5-level3 (+-2kv)
ESD-IEC61000-4-2 level4Redundant power supply:DC9-36VWork mode:TCP Client,TCP server,UDP ,HTTPDMore features:Synchronized baud rate:Change the baud rate,date bit,check bit and stop bit dynamically via network protocolm Serial/network heartbeat packet:The serial device server sends a heartbeat packet regularly to notify the server that it is active and maintains a normal network connection with a server;The serialdevice server notifies the serial device it is active via packet can also be used to actively capture sensor date.
Modbus Gateway:Support Modbus RTU to TCP protocal,Modbus TCP to JSON,Modbus multi-host polling
Virtual Com Software.
Applications :
Charging pile application case:N540 can connect the charging pile to the charging intelligent service platform to realize two-way data transmission between the charging device and the cloud platform.The billing information and power usage can be viewed remotely through the platform to facilitate operation and maintenance.
Industrial automation application case:The application of N540 in traditional industrial scenarios can effectively solve the problem that workers need to minitor equipment on-site,save labor cost and incress production effciency and safety factors.Data management makes the production process control more refined.
Unattended weighing:Connect the serial device server N540 to the barrier gate,the control center remotely controls the barrier switchh via Ethernet.Meanwhile,USR-N540 also support unified use of unattended weighing equipmen like license late snapshot serial port camera,weighing instrument,LED promoting screen,RFID card reader,vehicle induction coils,receipt printer and so on.
