Manuals of MQTT Modem ZHC493C
ZHC493C is a network IO product which support 2-channel dry (wet) node detection, 1-channel relay (COM, NO, NC) Output, 1 channel analog quantity (current 4~20mA) detection, 1 channel RS485/232 transparent, compatible with Modbus RTU/TCP protocol. With remote control as the core function, it is highly easy to use, users can easily and quickly integrate into their own systems to realize remote and local control based on LTE, RS485/232.
ZHC493C can quickly transmit data collected by various sensors to facilitate server summary and analysis, so as to realize real-time monitoring of data and promote the development of agricultural Internet of Things.
The basic function of ZHC493C is to realize the two-way transparent transmission through RS232/485 to 4G, support 4G, industrial design, built-in hardware watchdog protection, Has high speed, low delay characteristics.
AI voluntarily report description:
Disable reporting mode: Report all AI values cyclically according to the set cycle.
Report within the interval: When the set AI channel value enters the interval from outside the interval, all AI channel values are reported immediately and the cycle time is reset.
Report outside the interval: When the set AI channel value enters the interval from inside the interval, all AI channel values are reported immediately and the cycle time is reset.
