GDU 37X Installation Manual Page B-3190-01054-01 Revision CB.1.2 Shield Termination Technique – Method A.1 (Standard)For the following steps please refer to the drawings showing the installation of aJackscrew Backshell.1. The appropriate number of Jackscrew Backshells will be included in the particular LRU connector kit.Figure B-2 Method A.1 for Shield TerminationTable B-3 Shielded Cable Preparations for Garmin Connectors2. At one end of a shielded cable (item 2) measure a distance between “Window Min” to “Window Max”(Table B-3) and cut a window (max size 0.35”) in the jacket to expose the shield (Figure B-2). Usecaution when cutting the jacket to avoid damaging the individual braids of the shield. When dealingwith a densely populated connector with many cables, it may prove beneficial to stagger the windowsthroughout the “Window Min” to “Window Max” range. If staggering is not needed the “IdealWindow” length is recommended.Suggested tools to accomplish the window cut:• Coaxial Cable Stripper• Thermal Stripper• Sharp Razor BladeNOTEBack-shell SizeNumberof PinsStd/HDFloat Min(inches)Float Max(inches)Ideal Float(inches)WindowMin(inches)WindowMax(inches)IdealWindow(inches)1 9/15 1.25 2.25 1.75 2.75 5.25 4.252 15/26 1.5 2.5 2.0 3.0 5.5 4.53 25/44 1.5 2.5 2.0 3.0 5.5 4.54 37/62 1.5 2.5 2.0 3.0 5.5 4.55 50/78 1.5 2.5 2.0 3.0 5.5 4.5
