industrial 4g router with sim slot for IOT M2M area

Industrial-grade 4g router with sim slot USES a variety of wireless networks offered by major wireless operators to transmit remote data nondestructively and transparently for users.

In addition, industrial 4g router with sim slot also has some extended functions, such as intelligent wake-up and power off restart mechanism, automatic acquisition and active reporting, data center domain name resolution, PPP layer heartbeat /ICMP detection /TCP heartbeat link detection mechanism, remote parameter configuration/remote firmware upgrade, etc. These extended functions can enhance the reliability of industrial-grade DTU, ensure stable data transmission, no packet loss, and facilitate the use and maintenance of users.

Industrial quality, stable operation in harsh environment, strong and durable industrial-grade metal shell, high and low temperature resistance (-35℃to 75℃), wide pressure (5V-35V); Super damp proof, lightning proof, anti - electromagnetic interference ability, to ensure the stable operation of equipment in bad environment.

Wide power range design, built-in watchdog, can be suitable for a variety of field environment applications, provide RS232/RS485 communication interface, fully support industrial configuration applications, OPC Server, support virtual serial port.

Automatic analysis and processing of all kinds of situations, to maintain a permanent online state, to provide a stable and reliable network passthrough channel, master the key core technology, using the unique external TCPIP protocol stack software, data passthrough channel more stable and efficient.

It provides multiple network online modes, such as always online, closed module when idle, standby mode when idle, and supports multiple Master and standby data centers. In case of failure, it can automatically switch to the corresponding standby center. It supports TCP Client, UDP Master mode, AND TCP-ZSD and UDP-ZSD modes based on mountain encapsulation.
