Power Up Getting Started
GETTING UP AND RUNNING
To get started with a JNIOR you will need a power supply or some source of
power. In many cases the JNIOR ships in bulk to integrators and power
supplies are obtained separately since they depend on the destination country.
That often means that you might be handed a JNIOR without a power supply. Any
roughly 12 VDC source capable of supplying at least 1 AMP will work.
Power supplies for the JNIOR may be supplied with the 4-position screw terminal
connector. More recently the power supplies are equipped with a 2.1MM I.D.
5.5MM O.D center positive barrel connector. A short adapter accepting the barrel
connector provides the 4-position connection for the JNIOR. In addition there
are four 8-position connectors provided.
If the barrel adapter is not available you can cut the barrel connector off
a suitable supply, strip and tin the wires as needed. See
PWR for wiring
details.
With power applied to the JNIOR the Blue LED will illuminate. The Orange LED
illuminates briefly during boot. This orange status LED has many uses and
may flash at times to indicate activity.
NOTES
The Series 3 JNIOR used a Green LED to indicate power. The legacy Series 3
units are not recommended for new applications.
