Parameters of ZHC4941

• Introduction​ of 4G IOT Cellular Modem

• 4G IOT Cellular Modem ZHC4941 is an industrial-grade 4G RTU that provides 8 DI, 8 DO, 8 AI and 1 RS485/232 interface, supports local logic processing operations, automatic acquisition and active reporting, Modbus RTU/TCP adaptation, and automatic threshold calibration Special functions such as reporting, configuration software docking, dry and wet node IO detection, support one-to-one, many-to-one network.

Working Mode of 4G IOT Cellular Modem

1.HTTP Client
Support serial data transmission to designated server via HTTP.
2. TCP Client
The serial server actively initiates a TCP connection to the server. If it fails, it will continue to reconnect until it succeeds. If the connection is successful, the server and the serial device can perform two-way transparent data transmission.

• Application of
• 4G IOT Cellular Modem
• 
  After the device is powered on, remote control can be achieved through the transparent cloud, the light control state can be adjusted through the PC or APP, and the light can be directly turned on and off through the local switch.
  It can realize all-weather, multi-directional monitoring of the scene, saving manpower and material resources.
