Connecting AIS TRANSAS T105 to a computer


Connecting AIS TRANSAS T105 to a computer

There are 2 options:


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" 

Use a digital voltmeter to measure the voltage across the signal line with respect to 
ground. If the voltmeter shows a negative voltage, then the line on which the
measurement is taken  belongs to the category "A", the positive voltage indicates a signal 

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.

In the terminal box, jumpers are available to select an alternative terminal configuration 
for connecting data input from the remote equipment. The following 
terminal configuration options are available: 
  • R terminal for 120 ohms, recommended for a cable longer than 10 m. 
  • RC 120 Ohm per volt. / terminal device at 1 μF. Not used. 
  • No terminal device is available, it is recommended for a short cable, the length of which is less than 10 m (if included).
Select the appropriate terminal option for data entry using the 
jumper next to the data entry terminal in the terminal box. Jumper settings for each 
terminal version OPTION 2 There is a 9-pin D-shaped connector on the back of the T105 transceiver. This connector allows you to directly connect to the RS232 personal computer interface  and can be used to install, diagnose or connect an external display.  The default settings for this interface allow you to connect to the ECDIS or electronic card system  and duplicate the 'External display' port of the terminal box.

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.
