OP7100 18 Getting Started
Initial OP7100 Setup
Parts Required
• 24 V unregulated DC power supply capable of delivering up to 1.1 A
• Serial cable
The necessary parts are supplied with the Tool Kit.
Setting Up the OP7100
1. Remove the green power connector shown in Figure 2-1 from the back
of the OP7100.
2. Attach the bare leads from the power supply to the terminals on the
power connector as shown in Figure 2-1.
3. Plug the connector back into the power connection header at the back
of the OP7100. Watch the polarity of the connection so that the banded
wire from the power supply goes to DCIN as shown in Figure 2-1.
Figure 2-1. OP7100 Power Supply Connections
Be careful to connect the power supply wires to the correct
screw terminals on header J8. The OP7100 may be destroyed
if the power supply is connected to the
wrong screw terminal.
A protective diode prevents damage to the OP7100 if the
power supply polarity is reversed.
4. Plug the power supply into a wall outlet. The display should now light up
with the demonstration screens shown in Figure 2-2.
