Radio Modems

The SC105 Interface supports communications between a Campbell Scientific datalogger and an RS-232 DCE device. Common DCE devices used with the SC105 include our Raven100, Redwing100, and Redwing105 cellular transceivers as well as third-party radios and modems. The SC105 provides internal buffering that temporarily stores data. This allows th ...more

The RF310M Modem provides the communication interface between one of our dataloggers and a Maxon radio. The modem is typically powered by the 5 V power supply from the datalogger's serial I/O port. ...more

The RF232A includes a 110/220 Vac to 12 Vdc transformer, RF95A modem, RS-232 port, and internal mount for a radio. The RF232A is always located at the base station computer and serves as a link to field stations and repeaters. ...more

The Raven110 GPRS (General Packet Radio Service) modem is an Airlink product made for use on ATT/Cingular cellular networks. ...more

Located at base station computer, the RF310B Base Station serves as link to field stations and repeaters. This base station is compatible with Maxon radios. It includes a 110/220 Vac to 12 Vdc transformer, RF310M modem, RS-232 port, internal mounts for an RF310-series transceiver, and 7026 cable. ...more

The 905U-D radio modem module provides RS232 or RS485 connections by radio. It is a low cost wireless alternative for linking data loggers and supervisory computers.The 905U-D has been designed to be easy to use and simple to install. It uses a part of the radio spectrum which does not require a radio license in most countries. ...more

The R&S VT3050 is a member of the R&S M3TR family of multiband tactical radio systems. This power amplifier supports continuous operation across the 30 MHz to 512 MHz band with 50 W transmit power. The R&S VT3050 meets the need for both military voice and data communication in all analog and digital fixed frequency and frequency ho ...more

Different UUT technologies require different TPS development skills. DRS has developed TPSs for the following types of UUTs: Radio Frequency (RF) LRUs and SRUs: DRS has developed TPSs for RF avionics and communications equipment (modems, HF and UHF radios, TACAN, IFF, etc) as well as for Radar LRUs ...more

The Model BAMHC solves this problem by providing hardware handshake control for radio frequency and other modems requiring the RTS line to control the transmitter. The BAMHC allows the use of legacy or low cost systems without the expense of updating to modems with buffering or built-in RS-485 interfaces. ...more

Featuring the range and power of a licensed narrow-band radio, with the convenience and size of a unlicensed spread-spectrum radio, the RV-M3-M is a narrow-band VHF data radio modem operating on the unlicensed MURS radio channels. No other unlicensed radio can match the range of the RV-M3-M.  With a link-margin of over 147dB, it will work wel ...more
