This is information about a communication time test with an oscilloscope to measure and show how fast our long-range LoRa technology works. Below is a picture of the data communication time. The Green pulses were inbound 16 bytes of data on a UART into Radio #1 at 38400bps. The Yellow pulses are the outbound 16 […]

Electronic communications is all about interlinking circuits (processors or other integrated circuits) to create a symbiotic system. For those individual circuits to swap information, they must share a common standard communication protocol. Many communication protocols have been designed to achieve data exchange. The most common serial communication protocols are RS232, RS485, RS422, USB, and Ethernet. […]

RS-485 is a two-wire connection, with the pair of wires transmitting and receiving data. With the RS-485 feature enabled (ATIO 2 command), the 9-pin serial I/O connector on the front of the Raveon data radio modem model M5 and M7 will be put into the RS-485 mode of operation. The serial I/O connector is a […]

A leaky feeder is an underground communications system used in underground mining and other tunnel environments. It consists of a coaxial cable run along tunnels which emits and receives radio waves, functioning as an extended antenna. The cable is “leaky” in that it has gaps or slots in its outer conductor to allow the radio […]
