CHAPTER 2: HANDLING GUIDELINES FOR AXN MODULES 11
Cables and shielding
All cables should be shielded and the shields connected to the AXN through the connector backshells. If the
backshells have shield terminations then use these, otherwise bend the shields back and clamp them under the
cable clamp. The alternative method is to use a short pig-tail and take this to the CHASSIS pin on the AXN
connector. This method is acceptable but it is not the preferred method as it may result in a short length of
unscreened signal cable.
Signal cable shields should ideally only terminate at the AXN end. Bus cables may terminate at both ends as
stated in the relevant bus specification document.
Figure 11: Shielding
Curtiss-Wright recommends the use of twisted pairs with an overall foil shield. Wires should ideally be silver plated.
