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.  […]

Raveon manufactures a line of GPS devices to protect the lives and safety of peple in remote and dangerous areas. Firefighters have a very difficult and dangerous job, and deserve the best communication possible. Voice communications is often a huge challenge in wild-fire fighting, and Raveon’s Atlas GPS transponder can provide an additional level of […]

Raveon’s M7 series radios are well-suited for underground mine radio data communications. With the fastest Transmit / Receive turn around time in the VHF/UHF radio modem business, your polled telemetry system will operate fast and efficient within an underground data system using a pair of cables one of which is a radiating cable the other […]

Leaky Feeder Radio Systems (using a radiating cable) All Raveon data radios can be equipped with a radiating coaxial cable as an antenna for use as a leaky feeder system in areas such as, underground mines and railways, inside industrial buildings, and any other enclosed area where direct line of contact may be difficult to […]

VHF and UHF antennas are easy to find, but 220MHz band antennas for data radio modem are more difficult to find.  This Tech Blog article provides links and ideas for sourcing 220MHz mobile antennas and 220MHz base station antennas. 1.   Overview Raveon produces data radio modems at 200 MHz for Machine-to-machine (M2M) and SCADA applications.  Commercial […]

TDMA systems are often used to send consistently timed, periodic data. In these situations, system designers face the challenge of adjusting the rate data is sent to the modem to match the TDMA parameters. With Automatic Message Delineation, this constraint is removed. Instead, the modem is allowed to detect message boundaries and send only the […]

Ouput Data Framing is used when it is necessary for the device connected to the M7 data radio modem to wake from sleep or enter an appropriate mode to receive data.  Using a serial port handshake line, an M7 data radio can signal a listening device to wake up before outputting data, allowing the terminal […]

In the M7 radio, Sleep Mode 1 is enabled with the ATSM 1command.  There also must be 3 components installed on the circuit board of the M7 radio to allow sleep mode 1 to work. It is highly recommended that this modification be done at Raveon, or by very qualified technician skilled in fine-pitch soldering.  Damage to […]
