 ==== The Stack ==== ==== The Stack ====
-Connectors on the stack modules carry power lines 0V and +5V for the electronics on each board, attached devices may require separate supplies. There are four control lines, these are Data out, Data in, Clock and Strobe. When the interface receives a message the Strobe line is activated in order to read the current state of Inputs into the shift registers. The Clock is then activated in multiples of 8 pulses and data is sent out and received by the interface. When shifting is complete the Strobe line is activated again to output the new data to the layout devices.+Connectors on the stack modules carry power lines 0V and +5V for the electronics on each board, attached devices may require separate supplies.
