External power connectors
External power can be connected to either power connector J1 (barrel connector) or J2 (terminal block). Do not
attempt to apply power to both power connectors simultaneously.
 Connector J1 connects to the +12 VDC external power supply included in the SCC-8-8-2 shipment.
 Connector
J2 connects to a user-supplied +12 VDC power supply.
Figure 5 shows a schematic for external power connectors J1 and J2.
