ZHC2911 is an internally integrated GPRS (transparent/translucent) data transmission terminal. It is designed after careful consideration in terms of temperature range, vibration, electromagnetic compatibility and interface, stability, reliability, security, and related industry systems. become. Standard industrial interfaces, support for dual-band networks and integrated SIM cards make it an ideal data transmission terminal for mobile computing and multimedia applications. Through this GPRS industrial module , all devices with serial ports can realize the function of GPRS wireless data transmission. With remote/auto wake-up function and anti-disconnection mechanism.
ZHC2911 adopts a high-performance industrial-grade embedded processor, a real-time operating system as the software support platform, large memory, and embedded TCP/IP protocol stack with independent intellectual property rights. Provide users with a high-speed, stable and reliable virtual private network with always-on data terminals and multiple protocol conversions. Today we will take a look at the functional features and practical applications of this GPRS industrial module .
Features
