A significant portion of the Advance NDC Reference Manual catalogs hardware status codes. When a hardware module encounters an error, it generates a multi-character status code embedded inside an Unsolicited Status Message.
If you are currently troubleshooting or designing systems around this protocol, sharing more context can help narrow down the solution. Please let me know: aptra advance ndc reference manual
The manual outlines how the ATM acts as a "dumb terminal" driven entirely by host-defined states. State Tables
It adheres to NCR Direct Connect (NDC) protocols, allowing banks to leverage existing host systems while upgrading to modern, rich graphical user interfaces (GUIs).

Historically, the NDC protocol relied on rigid, character-based messaging streams optimized for low-bandwidth networks. Advance NDC breaks these limitations by introducing: Enhanced transaction flow states. Robust multimedia capabilities at the user interface. Extensive support for EMV smart card processing. Encrypted, high-security TCP/IP communication profiles. 2. Core Messaging Architecture
Aptra Advance relies on a state-driven model. Understanding how the NDC Reference Manual structures these states is key to building or debugging flows.
The operation of an ATM is state-driven, and the manual provides a detailed and message formats, outlining the different stages of processing a transaction. It details various state types, including: When a hardware module encounters an error, it
: Accessing engineer menus to test hardware components like receipt printers and cash dispensers. Electronic Journaling
When the Host sends a Dispense command, it must specify the counts.
: Advance NDC can emulate older versions of NDC+ or Diebold protocols. Ensure the emulation flags are accurately set in the configuration data.
