TESTING AND PROGRAMMING YOUR ICI1
To begin testing the ICI1 we will need the following items:
AC Power supply between 9 and 15VAC or..
DC power supply between 9 and 15VDC.
A remote control
Its finally time to apply power to your kit. Please be sure before you do that
you clear the bench of any scrap component leads and have one final look at
your solder connections before you proceed. Again, time spent here can
prevent problems encountered during testing and can avoid damaging any of
the components.
Recalling that the relays may be set for either momentary or toggle (on-off)
operation, it’s time to decide how you want to configure the outputs. If you
desire momentary operation, install a jumper strap in the respective OP1&2 or
OP 3&4 position.
Configure the jumper strap in the OP 1&2 position.
Configure the jumper strap in the OP 3&4 position.
Remember that these can be easily changed at a later time, so we
recommend that for initial test you omit these jumpers so that it is easier to
verify the operation of each individual relay.
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
programming, we will use these jumpers to count up in binary for all four
states.
Configure the jumper strap in the O SEL position.
Configure the jumper strap in the 1 SEL position.
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 10 K ohm resistor will pull the associated pin
high. This also helps to keep you from misplacing the jumpers and will keep
them handy for future programming. By setting the jumpers on these pins
you’re getting ready to program the 0,0 position on the ICI1.
