 ==== 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.

 ==== PTP ==== ==== PTP ====
-Point to Point, is the designation for a self contained RPC system consisting of two identical PTP interface modules connected by a 4 pair (cat 5) data cable. One module is fitted with a link that designates it as the Master which controls the data flow to and from the Slave module. Each of these modules has a 'stack' where the Input on one module matches the Output on the other and vice versa. Thus an input change at one end becomes an output change at the other end. +Point to Point, is the designation for a self contained %%RPC%% system consisting of two identical PTP interface modules connected by a 4 pair (cat 5) data cable. One module is fitted with a link that designates it as the Master which controls the data flow to and from the Slave module. Each of these modules has a 'stack' where the Input on one module matches the Output on the other and vice versa. Thus an input change at one end becomes an output change at the other end. 
 The PTP system operates independently, requiring no computer interface module, and accommodates up to 960 inputs and outputs from both ends simultaneously, with an update rate of approximately 20 times per second. The PTP system operates independently, requiring no computer interface module, and accommodates up to 960 inputs and outputs from both ends simultaneously, with an update rate of approximately 20 times per second.
