Module provides eight channels, and is equipped with professional set-up software for the user to change parameters, the module is transparent transmission mode, no user-written set and transmission procedures; you can transmit data of any size. Module is small, the use of voltage is wide, easy to use’s Applications： Features： ※ Water, electricity, gas, heating automatic meter reading system ※Frequency: 915MHz ※ Wireless smart terminal PDA ※ Wireless Queue System ※ Wireless alarm and security system ※Smart Card ※Medical and electronic instrumentation automation control ※Intelligent teaching equipment ※ Intelligent home automation and lighting control ※ Wireless electronic scale ※ Distance:1200m(1200Bps) ※Modulation:GFSK ※ Transparent transmission ※ Built-in watchdog to ensure long-term reliable operation ※ UART/TTL、RS232、RS485 Interface ※Convenient and flexible ※Almost 512 bytes data buffer ※Suitable for built-in installation JiZhuo Technology EZ50 Wireless Serial Radio Modem SHENZHEN JIZHUO TECHNOLOGY CO., LTD TEL：0755-83304518 83308451 Tech:0755-61319411 61319410 WEB: http://www.jizhuo.com - 2- EZ50 wireless module, the use of ISM frequency band, without application frequency; can be set to 8 communication channels, transmit power of 50mW (17dB), high receiver sensitivity-121dbm, size 110mm * 85mm * 25mm (without antenna base) , a large number of the billing system to use, very convenient for users to embedded wireless systems. EZ50 the use of transparent transmission, in order to ensure the reliability and stability of the user's system, plus the transmission checksum or CRC checksum error detection mode, the error data retransmission. Transceiver module buffer of 512 bytes, means that users can be in any state 512 bytes of data transfer , when the speed is greater than the serial port is set to air rate, is theoretically unlimited length can send information packets, but does not recommend users to send long data packets, the proposed length of each packet data between 60 ~ 100B, generally not longer than the 120B, and recommended user program using the ARQ mode, the error data packets retransmission. As follows: If the actual error rate 10-4, users need to send 1KB about 10000bit information, if the 1KB data as a packet, sent at least theoretically, there will be a data error in the receiver, then the 1KB data can never be received correctly. If it is divided into 10 packages, each package 100B, then send 10 packets, the packets according to a probability of only 1 error, the error in the form of a packet retransmission by ARQ 1, although it took more than 1 packet and the efficiency decreased by about 10%, but it can guarantee all the information is correctly received. EZ50 set parameters, the market is no longer used wireless modules used in the traditional way to change the parameters of the jumper, causing long-term use because it brings bad, options less dynamic change is not easy, a lot of inconvenience. EZ50 using the serial port setting parameters easy and quick, easy set refers to the chip embedded in the user program and operating software in the background. Meanwhile module 1200/2400/4800/9600/19200/38400bps six kinds of rate and 8 frequencies; provide UART / JiZhuo Technology EZ50 Wireless Serial Radio Modem SHENZHEN JIZHUO TECHNOLOGY CO., LTD TEL：0755-83304518 83308451 Tech:0755-61319411 61319410 WEB: http://www.jizhuo.com - 3- TTL, RS232, RS485 three kinds of interfaces. Choice for users. In the work on, EZ50 There are two ways of working, first for the conventional model, which module is powered On, is in receive mode; you also can be sending data. The second is sleep mode, that is, through the power module in a dormant state, it must be user-controlled mode wake-up pin block, the module can send and receive data. In the application of EZ50 module, the module uses a wide voltage range, but also divided into two kinds of voltage, the first for the 5V power supply module, also known as conventional module, the voltage of DC 4.5V -5.5V. users in the use of power to DC power supply, the current must be greater than 200mA, but to choose a good power supply ripple.
