Setup And Testing - Ramsey Electronics ICI2 Instruction Manual

SETUP AND TESTING

To begin testing the ICI2 we will need the following items:
AC Power supply between 9 and 15VAC or..
DC power supply between 9 and 15VDC.
A remote control
It's finally time to apply power to your kit. Please be sure before you do that
the bench is clear of any scrap component leads and take one final look at
your solder connections before you proceed. Again, time spent here can pre-
vent problems encountered during testing, and can avoid damaging any of the
components.
Place a two pin header shorting connector in the SEL0 and SEL1 position.
This selects the 0,0 configuration for the first button. We pull down the two
pins of the microcontroller thru a 10 K ohm resistor to set the voltages at zero,
designating a digital "0" state for programming. When we continue the pro-
gramming, we will use these jumpers to count up in binary for all four states.
Please note that when using these "shorting jumpers" it is common practice to
position them on only one pin, offset such that they do not make contact with
the other pin in order to set the associated jumper with the logic "1", or 5 VDC
state. In this configuration the 10K ohm resistor will pull the associated pin
high. This also helps keep you from misplacing the jumpers and will keep
them handy for future programming.
Set the power switch to the "off" position, and plug in a suitable power source
to the power input connector. The correct range of values for supply voltage
is 9 - 15 VAC or VDC, and the current capacity is between 200 - 250 mA. Our
AC125 transformer is the recommended source for this kit but any wall wart
will do.
Upon energizing the switch a short chirp will be heard from the speaker and
the LED should illuminate. The LED should be lit initially but this will change
after we program the microcontroller IC.
