C Build the Cable
Strip the jacket (~1 inch)
In ProgressUse a cable stripper to remove the outer jacket without nicking any conductors. Expose approximately 1 inch of the twisted pairs.
Untwist & fan the 4 pairs
LockedCarefully untwist each pair and spread all 8 conductors flat. Work close to the jacket to preserve the twist as far as possible.
Arrange conductors into pins 1–8
LockedFor each end: (1) choose the standard, (2) click a wire chip to select it, then click an empty pin slot to place it. Click a filled slot to remove the wire and return it to the palette.
