- Introduction of LTE CAT 1 Modem ZHC4013
ZHC4013 is a 1 serial port transparent transmission network IO product, compatible with Modbus RTU/TCP protocol. With "remote control" as the core function and high ease of use, users can easily and quickly integrate into their own systems to realize remote and local data collection based on LTE and RS485.
The ZHC4013 host computer software mainly provides users with functions such as "IO point test", "parameter configuration", and "firmware maintenance". The upper computer adopts serial communication. Use USB to RS485 tool to connect ZHC4013 and PC, select the corresponding serial port and open it. (Device default serial port parameters: baud rate 115200, data bit 8 bits, stop bit 1 bit, no parity)

| Check bit | Check bit | None/Even Check/Odd Check |
- Function of LTE CAT 1 Modem ZHC4013
ZHC4013 support MQTT.When the device actively pushes data, it will select the mode according to the option of Active Data Reporting. Can directly connect to the client server, and supports data interaction with the device through protocols such as Modbus RTU/TCP,JSON. Customers can also collect data and monitor the equipment through the Zongheng cloud platform which provide API interfaces info.
| Special Functions |
