Understanding Your Scanner
The RealScan 7892 is available in two models: 7892-0100 and 7892-0200. The 7892-0100
offers IBM, RS-232, and OCIA communication, and permits you to change among these
three programming types. It can be connected to the host terminal through a standard
interface connection or through a USB connection.
The RealScan 7892-0200 offers PC Keyboard Wedge communication only. This model is
designed to address the needs of retailers whose point-of-sale application does not
accept scan data through a communication port.
Power for the RealScan 7892 is provided through a wall adapter Power Module or
directly from the host terminal. Input voltage to the RealScan 7892 must be +12Vdc.

Scanner Location
When identifying a location for your NCR RealScan 7892, you must consider the length
of the connecting cables. The electrical outlet used for the Power Module can be
approximately 74 inches (188 centimeters) from the host terminal. Depending on which
Scanner Module Cable you have, the scanner can be approximately 6.6 feet (2 meters)
or 13.1 feet (4 meters) from the host terminal or PC. However, these distances are
normally shorter depending on how you route the connecting cables. You also want to
be sure that the Scanner Module Cable is long enough to permit the scanner to be
picked up when required for large packages.
Like any electronic device, your RealScan 7892 should not be located in direct sunlight.
Temperatures above 104 degrees Fahrenheit (40 degrees Celsius) can occur when
sunlight falls on objects through windows or on an outdoor checkstand.
