Iron Gate

The Iron Gates are items added by BuildCraft to control and/or interact with all pipes of BuildCraft via one configurable function (see Usage). The next tier is the Gold Gate with four configurable functions. The gate has an AND and OR version plus a Clock Timer, Redstone Fader, Light Sensor and Autarchic design.

Recipe
The player can choose the desired mode (AND or OR) if he has placed all needed resources in the Assembly Table, and the choosen one is produced.

Usage
The 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. But with the AND version, both preconditions in the right slots must be True before the gate executes the options in the left slots. With the OR version, only one precondition must be True to execute the corresponding option in the left slot. The bars between the left and right slot light up red when the precondition is currently True.

With a right-click the player can open the GUI, which has four slots (two left, two right). All slots can be configurated by clicking in it. The possible options depends on the pipe where the gate was mounted:
 * All options like the standard Gate (goto)
 * Furthermore the 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 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:
