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 do fine.
Power supplies for the JNIOR are supplied with the 4-position screw terminal
connector. JNIORs purchased without power supplies come with a 5-piece
Connector Kit containing the screw terminal blocks for the I/O and POWER
connectors on the unit. There are 4 of the 8-position connectors and 1 with
4 positions for POWER. When power supplies are included a 4-piece Connector
Kit is supplied with just the 8-position connectors given that the
4-position connector you need is already on the supply.
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.
The Series 3 JNIOR used a Green LED to indicate power. The Series 3 units
are not recommended for new applications.
