Description of the NMEA amplifier
The AMN010-2 is a high efficiency NMEA amplifier. It corrects and
amplifies the NMEA signal and send it on 4 independent NMEA
outputs, which allows you to connect a device (eg, GPS) to
multiple NMEA devices without risk of disruption due to an
overload of the NMEA bus. Its NMEA input is optically isolated to
eliminate the risk of disruption from ground loops or floating
reference levels. Entry does not load the NMEA source to which it
is connected. Its powerful and independent outputs can be used
with any NMEA device whatever its input impedance. It solves the
problems encountered with some devices where NMEA input becomes
very low impedance when its power is off. It has an auxiliary
input and output for coupling as many AMN010-2 as necessary to
obtain the desired number of NMEA outputs. Its amplifacation ratio
is greater than 1000. It works up to the 38400 baud (normal
baudrate of NMEA0183 is 4800 baud), which allows you to use
it also with AIS signals.

Why use a NMEA amplifier?
An NMEA output should never be connected directly to several NMEA
inputs due to the low impedance of NMEA inputs. There is a risk of
loss of data and information used by different devices are not
reliable because outdated. One device can disrupt all other
Incorrect connection of
several devices to a NMEA output:
Overloading the GPS NMEA output may cause data loss and
malfunctions. Some devices cause a total collapse of the
NMEA signal if they are directly connected to the NMEA bus
while they are off.
Correct connection of several
devices to a NMEA output:
The output of the GPS is no
longer overloaded and the signal is sent with its optimum
level to all devices. Each output is independent. A device
can no longer disrupt the others.
The use of an amplifier NMEA is the
assurance of a safe and reliable NMEA network. The reliability of
NMEA data is very important in the case of the use of an autopilot
system controlled by the NMEA bus.
If more than four
outputs are required:
The NMEA amplifier AMN010-2 has a special intput / output for
coupling as many MNEA010-2 as necessary to obtain the desired
number of NMEA outputs without using any power output for
Coupling of 3 AMN010-2 in order to
provide GPS data to 12 devices:
The first module receives GPS data
on the normal NMEA input. Data is available on the 4 power outputs
(1-4). The coupling output is used to send data to the
second module which receives data on its coupling input. In
addition to providing data on the power outputs (5-8), it provides
data to the third module by its coupling output... It is thus
possible to connect as many modules as required to obtain the
desired number of outputs.
