After this, the PC keyboard’s left or right arrow key can be held
down to generate a steady stream of programming signals out of
the parallel port. The CLOCK test point on the AD8150
evaluation board can be monitored with an oscilloscope for any
activity (a user-supplied printer cable must be connected). If
there is a square wave present, then the proper software driver
is selected for the PC’s parallel port.
If there is no signal present, then another driver should be tried
by selecting the Parallel Port menu item from the File pull-
down menu selection under the title bar. Select a different
software driver and carry out the above test until signal activity
is present at the CLOCK test point.
SOFTWARE OPERATION
Any button can be clicked in the matrix to program the input-
to-output connection. This will send the proper programming
sequence out of the PC parallel port. Since only one input can
be programmed to a given output at a time, clicking a button in
a horizontal row will cancel previous selections in that row.
However, any number of outputs can share the same input.
Refer to Figure 42.
A shortcut for programming all outputs to the same input is to
use the broadcast feature. After clicking on the Broadcast
Connection button, a window will appear that will prompt the
user to select which input should be connected to all outputs.
The user should type in an integer from 0 to 32 and then click
OK. This will send out the proper program data and return to
the main screen with a full column of buttons selected under
the chosen input.
The off column can be used to disable whichever output one
chooses. To disable all outputs, click the Global Reset button.
This will select the full column of OFF buttons.
Two scratchpad 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’s
storage memory should be used. The Save and Load selections
can be accessed from the File pull-down menu under the title
bar.
