The Config ID is the "handshake." It tells the host which version of the state/screen database the ATM is currently running. If the IDs don’t match, the host will typically trigger a full download of the configuration. State Tables

NCR APTRA Advance NDC (NCR Direct Connect) is the gold standard for ATM software. It connects self-service terminals to central host networks. This guide explains how to program, customize, and troubleshoot APTRA Advance NDC applications. 1. Architecture of APTRA Advance NDC

For organizations transitioning from older NCR Direct Connect Plus (NDC+) systems, Advance NDC offers a straightforward migration path. The APTRA Advance NDC Overview Guide highlights that Advance NDC supports existing NDC+ host communication, minimizing the need for extensive host-side changes. Key Differences to Note
