DIagnostics screen
• At the top of the screen the results of the ROM, RAM and data ports NMEA1, NMEA2
and RS232C are displayed as OK or NG (No Good). For any NG contact your dealer for
advice. (Ports NMEA1, NMEA2 and RS-232C require a special test connector in order
to test them. “- -” is shown when no test connector is connected.) PROGRAM NUMBER
and FPGA VERSION show respective program number and program version number
(XXXX).
• Heading and bearing signals are checked for proper input and the result displayed as
OK or NG. Tune and indicator voltages, antenna rotation speed, antenna motor voltage,
echo level and trigger frequency are measured and shown. TOTAL ON TIME and
TOTAL TX TIME show the total number of hours the radar has been powered and trans-
mitted, respectively.
• The INPUT NMEA window shows all the NMEA sentences being input to this radar. Sen-
tences are updated every second.
