The i-LINK is a versatile converter, equipped with a pulse coun-
ter input and two digital inputs and outputs. It is connected di-
rectly to the SATELLINE-1870, -1870E or -1915 radio modem
through an RS-232 serial interface. The pulse counter is used
for on-line control of e.g. water, electricity and gas consumption,
while the I/O-converter is used for transfer of contact informa-
tion and readings of field instruments like gauges. The i-LINK
is designed to receive pulse information in the Multipoint mode
only, whereas I/O digital status information can be transferred
in both Multipoint- and Point-to-Point systems. In a Multipoint
application, various information from a number of sub-stations
is gathered to the master station. In the Point-to-Point mode any
change of status in a digital input triggers a transmission in a
few milliseconds.
The i-LINK has two relay outputs. The combination of a pulse
counter and digital I/O-converter makes the system flexible and
versatile. Digital I/O ports can be used for driving motors and
controls, at the same time that the pulse input port is used for
metering other information.
Depending on the topology of the area wireless working dis-
tances can vary from tens of metres up to a few kilometres.

Technical specifications SATEL i-LINK
Pulse counter and I/O-converter for wireless applications
Remote reading of energy and water
meters of households and office proper-
ties in a densely inhabited urban area is
another feasible and labour-saving ap-
plication.
The readings of the electric meters are
connected to the digital input of the
i-LINK, converted to engineering units,
transmitted to the aerial control station
through the SATELLINE radio modem and
finally stored by the master computer.
At a farm, the i-LINK can be used for
automation of the control of irrigation
machines. The devices are switched on
individually, based on the reading of a
temperature or light sensor.
