There should be a redstone control feature in each chip specifying whether it ignores redstone (default), deactivates with redstone, activates with redstone or activates on pulse. Standard redstone would work with every chip in an interface pipe, but bundled cable could be used to activate specific chips based on the color of the signal. This would work using binary (i.e. white would work on the fist chip (1 = 1), orange would work on the second chip (2 = 2), magenta would work on both the first and second chip (3 = 1 + 2), etc.).
