SATEL launched the SATELLINE-3AS VHS, a versatile VHF data modem and network management software bundle designed for professional remote monitoring and control applications. The SATELLINE-3AS VHF transmits data at up to 19.2 kbits per second over ranges of up to tens of kilometers depending on the environment. Provided in a plug-and-play form, the modem comes in a tough housing measuring less than 14 x 7 cm (excluding the antenna) and weighs just 265 g. It is configurable and may be set up for data communications anywhere in the 138-174 MHz band, with up to 1600 or 800 channels spaced at 12.5 or 25 kHz, with data transmission at 9.6 or 19.2 kbits per second, and has carrier output power levels ranging from 0.1 to 5 W--depending on the coverage required (continuous operation at 5 W requires an additional heat sink). The radio also offers a universal serial interface for connection to local equipment. It is compatible with RS-232/422/485 standards, and can be programmed to operate at a variety of data rates between 1.2 and 38.4 kbits/second. Network Management System (NMS) software is provided with the modem; the software runs on a PC connected to a node which is configured as a master station. NMS provides a comprehensive suite of functions for both creating and managing radio modem networks, including the graphical design of topology and message routing or repeater functions, remote modification of settings, and logging and trending of field data. Also included are diagnostic reporting facilities: RSSI (received signal strength indication), indication of the power source voltage level and internal temperature. SATELLINE-3AS VHF modems comply with FCC CR47 part 90 and EN 300 113/300 220 Class 1 specifications. (Satel, Salo, Finland)
