The SATELLINE-1915 operates freely in North America using Frequency Hopping Spread Spectrum technology within the non-licensed 902 - 928 MHz ISM frequency band.
Built in Polling for Remote I/O
Designed specifically for serial, digital,
or analog devices and sensors, the 1915 often
eliminates the need for serial conversion
to Ethernet protocols (TCP/IP, UDP and others)
as a substitution for a polling master. The
master 1915 radio can be configured to poll
each radio modem in sequence for data collection.
Advanced Data Handling
Defined by its superior data integrity, packet
transfer dependability, receiver sensitivity
and advanced signal selectivity; the 1915
delivers the best in spread spectrum radio
technology. Internal software features
selectable error correction, which improves
the functioning of the radio under interference,
while a variety of data flow utilities
enhance communication reliability using
configurable handshaking, acknowledgements,
packet re-transmission, and error checking,
retries & acknowledgements, flow control
and others make the most of available network
resources. Message Routing functions facilitate
easy setup of large networks with minimum
Maximum Legal Power
Adjustable transmitter power from 1 mW to
a full 1 Watt make the 1915 ideal for a
wide variety of indoor and medium-range
or light duty outdoor applications. Connecting
at ranges of 1/2 mile or more in dense
urban environments, the 1915 can tear across
open terrain to distances of more than
10 miles. Advanced Data Handling
The 1915 features a low power sleep mode
to conserve power consumption in battery
or solar powered installations
Enhanced Message Security
The SATELLINE 1915 contains
5 separate layers of security, including
256 bit AES encryption, which provides
protection to both intrusion and monitoring.
The SATELLINE 1915 provides a number of advanced data transfer functions for maximum reliability. Each radio modem of the network can be used as a repeater, base, remote or mobile unit and is suitable for a variety of data applications needing to reach up to several miles with few obstructions.
Default communication is fully transparent, which makes message routing directly compatible to most user protocols. With advanced configuration, a network can cover large areas with multiple hops and repeater stations.
The SATELLINE 1915 error rate is minimized
by means of advance checking and correction of the data packets.
In Forward Error Correction (FEC), the data packets are split
into several blocks. The radio modem adds correction information
inside the blocks during transmission. Selectable hopping channels
and delay slots increase throughput by reducing interference.
The Data Transfer mode of the SATELLINE 1915 includes
a Command Program function in which the radio channel and addresses
can be changed online from the serial port of the radio data
modem. The changes are effected by means of common and specialized
AT commands, which are entered amidst ordinary data.
