SOFTWARE OPERATION
This sends out the proper program data and returns to the main
screen with a full column of buttons selected under the chosen
input.
Click any button in the matrix to program the input to output
connection. This sends the proper programming sequence out
the PC parallel port. Since only one input can be programmed
to a given output at one time, clicking a button in a horizontal
row cancels the other selection that is already selected in that
row. However, any number of outputs can share the same input.
The Off column can be used to disable the desired output. To
disable all outputs, click Global Reset. This button selects a full
column of Off buttons.
Two scratch pad memories (Memory 1 and Memory 2) are
provided to conveniently save a particular configuration.
However, these registers are erased when the program is
terminated. For long term storage of configurations, the disk
storage memory should be used. The Save and Load selections
can be accessed from the File menu.
A shortcut for programming all outputs to the same input is to
use the broadcast feature. Click Broadcast Connection and a
screen appears that prompts the user to select which input
should be connected to all outputs. Type in an integer from 0 to
32 and then click OK.
