Because of its Onboard ECOS-OS, TCP/IP stack small form factor and extremely low power Real-time clock for wakeup and time stamps consumption, the RN-121G is perfect for mobile Accepts wide voltage range input 3.3V wireless applications such as asset monitoring, GPS 12VDC (RN-121 and RN-123) tracking and portable devices. The WiFly GX simplifies the integration and development of your Industrial voltage range input 6V 48VDC application by including an on board TCP/IP stack and (RN-125) networking application programs such as telnet and Switched power supply for external sensors ftp. The hardware requires only four connections Supports Adhoc and infrastructure networking (PWR, TX, RX, GND) to create a simple wireless data connection. Additionally, continuously sampled analog FCC / CE / ICS certified and RoHS compliant. inputs transmit audio, temperature, motion, or acceleration data without requiring additional hardware in your end application. The WiFly GX module uses a Applications straight forward ASCII command set for configuration Wireless thermostats and programming. Once the WiFly GX is set up it can RS232/RS485 cable replacement automatically associated and authenticate with a Remote equipment monitoring network, making your device accessible worldwide. The WiFly GX includes a high-speed UART and SPI Scanners, GPS and measurement systems interfaces that allow high-speed data transfer.
