A.2.1.1 Electrical connection
The data connection between the C-COM module and the chart plotter is
done by using a serial port (it is possible on some chart plotter to a port of your
choice). To make the electrical connection refer to Par. 2.5.4.
A.2.1.2 Verification of C-COM module
The Modem Test (can also read; SYSTEM TEST *) makes it possible to test
the and verify a connection between the C-COM and the chart plotter.
Note (*)
To start the SYSTEM TEST switch on the chart plotter using ‘POWER’ and any other key.
The Modem Test controls that there is a communication between the chart
plotter and the C-COM by for a short time transmitting a serie of diagnostic com-
mands to the C-COM and verify the result.
If the chart plotter is build with two serial ports, it is possible to choose
which port to use for connection with the C-COM module.
The diagnostic screen for Modem Test, will show the following information:
a. MODEM OK: #
b. MODEM ERROR: #
c. MODEM TIMEOUT ERROR: #
a. If the number (#) by the MODEM OK is different to 0, it is an indication that the
connection between the chart plotter and the C-COM module is established and the
C-COM is responding correctly. No problems have been found.
b. If the number (#) by the MODEM OK is different to 0, it shows that the connec-
tion to the C-COM module has not been made - the C-COM module may be defect.
c. If the number (#) by the MODEM TIMEOUT ERROR is different to 0, it shows
that the C-COM module is responding but the link to the chart plotter has not been
made.
The error may be for one of the following reasons:
