FIRST TIME OPERATION
Become familiar with the locations of connectors before
getting started. See Figure 2-1. RPC-210 jumpers have
been set at the factory to operate the system immediately
using a 6 - 16 V supply. If you have a 5V supply, then
remove jumper W8 and connect the + 5V to P1 terminal
marked ‘5' . For first time operation, do not install any
connectors or parts unless specified below. Jumpers
should be kept in default positions.
1. Connect power.
A development system includes a power supply and
cable assembly. Refer to the next two paragraphs
for connection instructions then move on to
paragraph 2.
Development system power supply
Refer to Figure 2-1 on the next page. Connect the
red wire on the power cable assem bly (P/ N 1725) to
the terminal marked “E” on P1. Black goes to P1
terminal marked "G".
You may plug the power supply into a 120 VAC
wall outlet or power strip. Power may be applied or
removed from the RPC-210 board by plugging the
3.5mm connector from the power supply to the
power cable assembly.
Your ow n power supply
The RPC-210 needs + 5 volts or 6 to 16 volts at 300
ma. The RPC-210 has its own regulator which
supplies 5V to the rest of the card when power is
applied to the ' E' termin al.
Be careful when using "switching" power supplies.
Some supplies do not regulate properly unless they
are adequately loaded.
Make sure pow er is off. Conne ct the powe r supply
to one of the appropriately marked terminals on the
RPC-210 as shown below.
Power connector P1 is designated as ' 5' for 5 volts,
' E' for the external 6-16 volt input, and ' G' for
ground. Other terminals marked ‘B’ and ‘P’ are
discussed in Section 7, REAL TIM E CLOCK.
Connect power to P1 as appropriate from your
supply as shown below.
