Note
The additional tests in the System Test Menu are intended for factory testing. Faulty findings within these menus
is not necessarily a true result, as factory settings and equipment are often used during these tests.
15.6.1 RAM Menu
Make sure the EKP-IV is turned Off. While pressing and holding any other key, turn the EKP-IV On.
A new menu will appear on the display. Use the cursor key to select the RAM Menu and press
‘ENTER’ to select RAM Test or RAM Clear.
• RAM Test
‘ENTER’ on RAM Test to verify the integrity of the RAM. If the message “ERROR” appears the RAM
is physically damaged.
• RAM Clear
‘ENTER’ on RAM Clear to to activate, press ‘ENTER’ again to confirm (at this time if you do not wish
to clear RAM press ‘CLEAR’).
This operation will erase all Marks, Flight Plans, stored Track plots and destinations. It will also
return all selections (Input Data Format, selective display etc.) to original default values.
15.6.2 C-CARd Menu
To check the Compact Flash and its connector.
• Compact Flash Test
To test the Compact Flash. There are the following possible situations:
1 . If there is a Compact Flash inserted in the slot and there is not a malfunction, the name of the
Compact Flash zone and the message “OK” are shown.
2 . If there is a Compact Flash inserted in the slot, but it is a damaged Compact Flash, the name of
the Compact Flash zone and the message “Faulty” are shown.
3 . If there is not any Compact Flash inserted in the slot, the message “not present” is shown.
4 . If there is an User Compact Flash inserted in the slot, the message “USER CARTRIDGE” is
shown.
• C-CARD Connector
Indicates if there is a malfunction in the connector. It is used only in production.
15.6.3 Serial Ports
If you are having problems receiving data from the position-finding instrument, this test should help
determine the problem.
• Change Parameters
To change the parameters of the serial interface. This menu allows to select the Port (Signal Source)
between UART0 or UART1, the Baud Rate between 4800 or 9600, the Data Bits (Word Length)
between 7 or 8, the Parity between EVEN, ODD or NONE, the Stop Bits between 1 or , the
Polarity between “+” or “-”. Default settings are: Port = UART1, Baud Rate = 4800, Data Bits =
8, Parity = NONE, Stop Bits = 1, Polarity = +.
• Input Data Display
To allow the chart plotter to act as a computer terminal and display the incoming data exactly as
it received.
If the data displayed on the screen is unrecognizable, you may have selected the wrong input
parameters for your particular receiver, for example, NMEA-018 instead of NMEA-0183. Check
your receiver manual to be sure that you have selected the proper interface format. If the screen is
blank, you may have a broken connection, and no data is being received. Use ‘ZOOM IN’ to stop
