The Cricket Wireless System was designed as a highly accurate seamless wireless analog bridge that can convert most wired sensors or analog inputs into a seamless wireless connection between most any 4-20 ma, 0-5 VDC or 0-10 VDC sensor and data logger, controller or SCADA equipment, eliminating up to 20 miles of wiring.
The units consist of a wireless, bi-directional Master/Slave transceiver that allows from one to four channels of analog inputs and outputs. Each Master/Slave controllers has 4 channels of 12-bit analog inputs and 4 channels of 12-bit analog outputs allowing for a full duplex, bi-directional analog I/O. Each controller is also equipped with one optically isolated ON/OFF type input and output.
Most important features:
• 1, 2, 3 or 4 channels
• Inputs can be configured for 4-20 ma, 0-5 VDC or 0-10 VDC
• Outputs can be configured for 0-5 VDC, 1-5 VDC or digital
•Transmitter/Receiver setup via RS232 interface
• License Free ISM Band Worldwide under FCC part 15 and ECT 300.328
• 900 MHz and 2.4 GHz FHSS ISM band Transceiver
• Transmission Distance up to 20 miles (with Modified Antennas)
• Easy to install and set up
Note: Cricket Wireless Transceiver, Model RT12-4411, shown with included antenna. Transceivers are sold as a pair to provide a complete transmission function.
