A Power Supply is required with a standard 2.1mm barrel connector . It can be AC 7 12V or DC 9 - 15V . The conne ctor is inse rted into the power con nection socket as
shown, above.
The programming lead supplied is fitted into the Dongle case and the other end is
inserted into the programming interface on the board as shown.
The Dongle case i s co nnect ed to one o f the prin ter ports o n the PC. I f this is not LPT1,
then you will need to change t he printer port se tting in the so ftware—see s oftware section for details.

Note:
There are a number of jumpers on the board which are used to select different
operations and voltages. The default jumper settings are for programming operations at 5V JP1 Closed, with brown-out also set to 5V JP2 Open.
To carry out other operations, some jumpers may have to be removed—refer to
the relevant section for details. A full list of the jumpers and links are given in the
following table.
