6. Checking on NMEA data interface: See page.6-9.
Execute "[Menu] -> 9 -> 8 -> 2: TEST" to check inputted NMEA data. The display
box <GPS-1> displays GPS data inputted from the [NAV] port (J606) and the box
of <GPS-2> displays GPS data inputted from a port other than the [NAV] port.
NAV data of the <SPEED> and <HEADING> boxes are displayed when
there is a data input from any port. There is no restriction in data display by
NMEA Versions. However, data handling differs according to the setting of radar
types such as IMO and A types.
7. Loop Back test: See page.6-21.
When there is such a problem in the interface as no gyro or the NMEA data cannot
be received or no communication is allowed with the INS through the serial port, it
is required to identify whether the problem is on the destination side or on the FAR
side.
8. ERROR/ALM: See page.6-31.
Is not the ALERT-BOX displaying an error of the EPFS, the GYRO and etc.?
The causes of an error may differ depending on the presence of input, input
sentences and the setting of a radar type. For instance, the radar type is set as the
IMO, NMEA Version 3 or later is required.
9. Program updating: See Chapter 5.
Programs are updated by connecting the serial port of the computer and the
RS-232C port of the TB board of RPU-013. The cable to be used is a cross cable
(female-female, 9 pin D-sub).
When the serial port number of the PC is other than COM-1, specify COM-1 on
the side of the computer. Or rewrite to change the port number of each program
batch file so as to match with the COM port number of the computer. While
updating the DRAW program, never turn off the power or cancel updating halfway.
10. Connection of sub monitor: See page.4-74.
When connections are made to the sub monitor, Slave-1 outputs full-log video
signals and Slave-2 outputs semi-log video signals. Full-log outputs are video
signals with GAIN and STC not controlled while semi-log outputs are video
signals with GAIN and STC controlled.
