2.3 Monitor Unit
Two cables are terminated at the display unit: the signal cable from the processor unit (5 m
or 10 m cable) and the power cable from the ship’s mains. The signal cable comes with a
connector preattached to it for connection to the monitor unit. Fabricate the power cable as
below. Use DPYC-2.5 (Japan Industry Standard) cable or the equivalent.
For MU-190/231, see the applicable Operator’s Manual(s).
Fabricating the power cable
1. Cut armor of the cable by 40 mm.
2. Cut vinyl sheath by 35 mm.
3. Remove insulation of wires by about 10 mm. Fix crimp-on lugs to the cores.
4. Peel paint of the armor by 40 mm.
5. Cover the end of armor with vinyl tape.
40 mm: Peel paint.
