There are 2 options:
OPTION 1
In the AIS 105 class A terminal box there are ports for connecting external sensor inputs and output to external devices. Accordingly, there are inputs, there are outputs. At the request of the registers, a gyrocompass is connected to the AIS (it is possible together to start ROT - the angular speed of rotation from the gyrocompass) and GPS (position, time, SOG - speed relative to the ground, COG - course relative to the ground.) Below is a table for routing the inputs and outputs, indicating ports:
To connect an external device (computer or ECDIS, for example), the "External display" port is used.
IMPORTANT: When connecting several external devices, it is recommended to install the NMEA splitter to amplify the signal and prevent the failure of the port.
An example of connecting an external display is shown below in the figure. To determine the signal line "A" and "B"
line "B". If the voltmeter is not - simply connect to the device and check the correctness of the data arrival, if the data does not arrive - change the polarity.
The RS232 port is galvanically isolated from the input power source.
This means that no "extra" impact on your PC and back will not be. For example - without galvanic isolation, it is possible that when the sensor is connected, the mouse cursor randomly jumps over the screen.
