Furuno FR-2115/2125 manual Fabricating signal cable S03-74

Fabricating signal cable S03-74

1.Remove the anti-corrosive sheath by 500 mm. Remove the armor and vinyl sheath leaving 50 mm each approximately.

2.Fold back the armor and trim to suitable length. Then, slide the washer, rubber gas- ket, washer and clamping ring onto the cable in that order.

3.Unravel the outer shield to expose the cores in the outer layer. Then, unravel the inner shield to expose the cores in the inner layer. Label all inner cores for later identification.

4.Attach EMI cores to all inner cores and outer cores, and tie them with cable ties, etc..

Note: There are two types of EMI core, thick and thin.

5.Trim each core (except coaxial core) con- sidering its location on the terminal board.

6.Trim the inner and outer shields leaving 50 cm each. Twist shields together and attach crimp-on lug FV5.5-4 (blue, ø4).

7.Remove insulation of each core by 6 mm approximately. Attach crimp-on lug FV1.25-M3 (red, ø3) to each core.

8.Fabricate the coaxial cable. Make the length 10 mm longer than the shield to prevent wire strain. Attach crimp-on lug FVD1.25-3 (red, ø3) to coaxial cable.
