NCR RealScan 7882 Installation and Owner Guide

Step 1 - Installing Power Supply

and Interface Cables

Connecting the Cables to an NCR RealScan 7882

The RealScan 7882 can be powered through a wall adapter Power Supply or directly from the host terminal. The RealScan 7882 automatically detects which power source is being used. In either case, the input voltage to the RealScan 7882 should be +12Vdc. The RealScan 7882 current never exceeds 600mA. How the cables are connected to the RealScan 7882 depend on the type of interface connection being used.

Standard Interface Connection

1.Install the Interface Cable between the RealScan 7882 and the host terminal.

2.If using the wall adapter Power Supply, locate it in the checkstand at least

10 inches (25.4 cm) from the RealScan 7882 installed position. Be sure to locate the Power Supply where spilled liquids cannot fall onto it.

3.Fasten a Tie-Wrap around the Power Cable and the Interface Cable to help secure the Power Cable.

Note: If the RealScan 7882 is to receive power from the host terminal, omit steps 2 and 3.
