NCR RealScan 7882 Installation and Owner Guide

Communications Protocol

The Communications Protocol function identifies the communications protocol the RealScan 7882 is using. Scan the Diagnostics Mode and Hex 3 programming tags (must be first tags scanned after applying power). Three beeps sound after scanning the Hex 3 tag, identifying the programming tag. Next, the Status Indicator flashes green and a series of beeps sound that identify the communications protocol. Use the following table to determine the communication protocol.
