Typically, promotional display data files are developed on the system processor or a personal computer (PC), using a commercially available graphics software package. These graphic data files are formatted using the WinForm utility, and then downloaded from the host workstation and stored in the 5992.

The 5992 is loaded with its operating system at the factory, and is delivered in a fully functional condition. A lithium battery provides memory retention voltages for all RAM locations.

Communication Interface

The NCR 5992 communicates with a host workstation using one of two interfaces: EIA-232 or IBM-EIA-485. The interface cable used dictates the communication type.

An interface cable provides the required electrical conductors for signals between the host workstation and the 5992. Although two different cables are available; the one supplied is for the communications type specified in your order.

EIA-232

EIA-232 protocol transmission is a synchronous, half duplex. The data format is 7, 8 or 9 data bits, parity or no parity, and one stop bit. Baud rates up to 38.4 Kbps are supported by the device. However, the NCR diagnostics and utilities only supports up to 19.2Kbps. The 5992 can either manually select or automatically detect the host data rate.
