Autarchic Iron Gate

The Autarchic Iron Gates are items added by BuildCraft and a specific design of the Basic Gate to control and/or interact with all pipes of BuildCraft via one configurable function. The autarchic design has two additional options available to operate pipes autonomously (without engine) (see Usage). The gate has also an AND and OR version. The next tier is the Autarchic Gold Gate with four configurable functions.

Usage
The Autarchic Iron Gate can be placed on all types and sides of the BuildCraft pipes with a right-click. By holding the crouch-key and right-clicking the gate can be removed without to destroy the pipe.

Note: The basic function is that the gate checks the precondition in the right slot, and, if this precondition is true, executes the option in the left slot. The bar between the left and right slot light up red when the precondition is currently True. The difference between the AND and the OR version is when it will trigger an action. Both will trigger if one precondition is true, but if the AND version is used, and two or more conditions are set to trigger the same action, the action will only trigger when both preconditions are True. If the OR version is used and two or more preconditions are set to the same action, the action will trigger when either of the preconditions is True. The different to the Standard design is, that the autarchic design has two additional options (yellow marked in the table below), which are available for all pipes, but are only useful to operate pipes they need RF for example the extraction pipes.

With a right-click the player can open the GUI, which has four slots (two left, two right). All slots can be configured by clicking in it. The possible options depends on the pipe where the gate was mounted:
 * All options like the standard Gate (goto)
 * Additional options of the Autarchic Gates (goto)
 * Furthermore the Autarchic Iron Gate has the ability to interact with Blue Pipe Wire (in addition to Red Pipe Wire) to transmit and/or receive redstone signals over the BuildCraft own wire system. An example with a Diamond AND Gate is shown in the picture, but it is the same except that the Autarchic Iron Gate can only interact with the Red and Blue Pipe Wire. In the GUI the corresponding option is selectable if a pipe wire is connected to the gate (see below)

Additional options for pipe wire interaction
Following options are additional available for all types (kinesis, fluid, transport) if Pipe Wire is connected to the gate:
