15. Can the same ports be used for connecting a sub monitor?
See page.4-74.
There are two ports for connecting to the sub monitor, one for outputting semi-log
video signals and the other for full-log video signals. Select an appropriate port by
understanding the characteristics of each.
To use both ports for outputting same video signals semi-log or full-log, it is
required to modify the SPU board (03P9337).
To make the outputs of SUB DISPLAY-2 (SEMI-LOG: J618) same as the outputs
of SUB DISPLAY-1 (FULL-LOG: J617), follow the procedure below.
1) Remove the jumper (chip) of JP3 on the SPU board.
2) Jumper JP4 on the SPU board.
To increase the video level for the monitor:
SEMI-LOG output: Provide R356 (1 kohm) on the SPU board with a 1 kohm
resistor in parallel, and then the level will be increased by
50%.
FULL-LOG output: The applicable resistor is R364/1kohm but the level is not
increased so significantly.
16. Can the Radar-buoy connect?
No. Radar-buoy cannot be connected.
17. Which format should be used for HDG, AD format or NMEA format?
See page.4-42.
Either AD format or NMEA format can be used.
However, in case of AD format, input data to J608 on the TB board at the output
interval of 25 msec. In case of the NMEA format, input the HDT sentence to
J605 on the TB board at the speed of 38.4 kbps (IEC61162-2) and output interval
of 25 msec.
18. How many CU-200 can be connected?
See page. 4-48.
Two CU-200 can be connected via HUB-100. Setting is required for the 2
nd
CU-200. This setting is for the IP address of CU-200. The drives of CU-200s are
automatically assigned. The drive of the 1
st
CU-200 is A (left slot)/B (right slot),
and the drive of the 2
nd
one is C (left slot)/D (right slot).
Note:
For temporary measures just for a purpose of display of the coastline chart, the
coastline can be displayed by inserting the chart data card into J206 on the SPU
board and restart the unit. However this operation make the lid of the processor
unit left open.
