The SRL-35 is an IP67 (NEMA 6) classified UHF radio modem with a high power (up to 25 or 35 W) transmitter and wide 70 MHz tuning range. Designed for easy mobile use in demanding field conditions, the casing and connectors are waterproof and secured against dust.
In addition to the high output power and wide tuning range, the channel spacing is also selectable to be 12.5, 20 or 25 kHz. The SRL-35 is equipped with a LCD Display and a keypad used to indicate the current operating status, to change the operating channel, to adjust the power level and to set radio protocols (Satel/PDL/TrimTalk**).
The cost of operation is either free of charge or has a license fee, depending upon the local radio regulation in your region. The SRL-35 radio modem provides a reliable and real-time data communication over distances ranging from hundreds of metres up to 80 kilometres (optimal field conditions).
The SRL-35 radio modem used in networks are flexible, easy to expand and can cover a wide variety of solutions from simple point-to-point connections to large networks comprising hundreds of modems. Even for expanded networks, only one operating frequency is required. In a SRL-35 network, any substation can function as a repeater, too. In this operating mode (store and forward), the radio modem receives a message, buffers the received data, and transmits it further to another substation, using the same radio channel as in reception.
