The Infra-Redstone Cable is a block added by InfraRedstone. It transmits Infra-Redstone signals between components. Like normal Redstone, it must be placed on a solid block and transmits signals horizontally, horizontally down and horizontally up.
It can transmit a signal up to 64 blocks away from its source. If two signals are combined, then the result will be their bitwise OR. For example, combining a signal of 32 (100000) with a signal of 16 (010000) makes a signal of 48 (110000).
It is also used as a crafting component for several items, such as PCB.
