2.3 How to Connect the Signal Cable for FAR-1513,
FAR-1523
In order to minimize the chance of picking up electrical interference, avoid where pos-
sible routing the signal cable near other onboard electrical equipment. Also, avoid run-
ning the cable in parallel with power cables.
How to fabricate the signal cable
Fabricate the signal cable as follows:
1. Remove shrink tubing from the signal cable.
2. Remove vinyl sheath approx. 50 mm.
3. Wrap vinyl tape at the end of the vinyl sheath.
Cut sheath approx. 50 mm.
