Satelline 3ASD Radio Modem & Dipole – Available for rental, hire and ex-rental purchase from Ashtead Technology.
The Satelline-3ASd is a half-duplex radio modem suitable for a variety of data transfer applications, in particular ones demanding high speed and precisions. In addition to the maximum data speed of 19.2 kbps and channel spacings 25 kHz or 12.5 kHz, it offers a number of features and functions that are highly useful in the installation stage as well as in routine operation.
The Satelline-3As software includes a selectable error correction, which improves the function of the radio modem under interference.
Satelline-3AS is compatible with the interface types RS-232, RS-422 and RS-485. The software of the radio modem can be updated through the interface from a PC, without changing the hardware. The Model Satelline-3ASd is equipped with a LCD display of its own, which facilitates programming of the radio modem.
The amount of data transferred in a local area data communications network exhibits a tendency of continuos growth. On the other hand, the average size of the communications system is increasing. Satel's response to these market tendencies is the Satelline-3ASd, the first radio modem from Satel with a data speed of 19.2 kbps over the air. The data speed of the RS interface is selectable between 300 & 38400 bps.
