Extended Information
The Maxon SD-271-SD-274 Data Radios are designed to meet the needs for a variety of wireless applications. Include the optional GMSK (9600 Baud Rate) or the 4FSK (19200 Baud Rate) modem boards to add even more diversity to this cost effective radio. The modules incorporate the most requested mechanical footprint and BNC antenna connection. Transmit power settings from one to five provide the power needed on any job and the LED indicator gives instant on-sight status of the radios operation. Combine that with low current drain and fast transmitter/receiver attack times for operation in the harshest of system demands. The die cast aluminum cabinet/lid provides resistance to RF interference; and gives exceptional environmental durability in the most extreme conditions.
