FUNCTIONAL DESCRIPTION:

The DS3800HLNA is a MicroVAX Network Controller Card manufactured by General Electric as part of the Mark IV Series, used in GE Speedtronic Gas Turbine Control Systems. It connects a MicroVAX system or GE Mark IV controller to an external network, enabling communication with other computers, controllers, or devices.

The card provides a physical network interface, typically using 10 Mbps Ethernet via an RJ-45 connector. It manages data transfer between the system bus (such as Q-bus) and the network, converting parallel CPU data into network packets and vice versa. The DS3800HLNA supports network protocols like DECnet and Ethernet, offloading low-level communication tasks from the CPU.

It also monitors network errors and hardware faults, reporting them to the host system through status registers or LEDs. The card ensures compatibility with legacy systems, provides reliable communication, and protects the CPU from electrical disturbances on the network.

OPERATIONS:

The Network Controller Card is initialized by performing self-checks and setting up communication with the system bus. It continuously monitors the network for incoming data, captures valid packets, and transfers them to system memory while notifying the CPU of new data. When the CPU needs to send information, the card formats it into network frames, applies error checking, and transmits it over the network. The card manages communication protocols, detects and reports errors or collisions, and ensures continuous, reliable data exchange while maintaining compatibility with legacy systems.

COMPATIBILITY:

It integrates effortlessly with MicroVAX systems and GE Mark IV controllers that utilize Q-bus connectivity. It is compatible with both DECnet and 10 Mbps Ethernet networks, facilitating data exchange across legacy networks. The card works in conjunction with VMS and Ultrix operating systems, ensuring proper communication and system performance. Verifying firmware and hardware revisions against the host system ensures maximum reliability and avoids network conflicts.
