The message "Card x connected" is displayed if the connection is successful
You can now simulate the inputs via push buttons Inp1
through Inp5. The matching check box remains ticked off as
long as you keep one of the push buttons pressed down.
Always tick off the check box for the matching output if you
wish to test a digital output.
You can also conduct this procedure automatically : press
the 'output test' button or activate all outputs with the 'Set all
digital' button. Press the 'output test' button to test all digital
outputs automatically.
Test the analogue outputs with the 'set all analog' button and modify the output voltage with DA1 & DA2
Counter 1 & 2 are hardware integrated 16-bit counters, they are triggered by INP1 & INP2. You can test the counter
with push buttons Inp1 and Inp2 : the counter adds 1every time one of these two buttons is pressed. The
debouncing control allows you to determine the reaction time of the counter (0ms - 2ms - 10ms - 1000ms).
You can use the internal analogue voltage to simulate the analogue input via potentiometers ATT1 (RV1) & ATT2
(RV2). The scroll bars AD1 & AD2 change on the screen whenever you adjust the position of the potentiometers.
The "digital" value (0 to 255) of this internal analogue voltage can be read directly under the scroll bars.
