The DS200ACNAG1ADD Arcnet Connection CardAbout the DS200ACNAG1ADD
The DS200ACNAG1ADD is an ARCNET (Attached Resource Computer Network) Card manufactured by General Electric for their Mark V series. The Mark V is part of GE’s successful Speedtronic line of gas/steam turbine management systems.
This series has managed heavy-duty turbines since the 1960s, with the Mark V featuring:
Triple-redundant backups on all critical controls and protection parameters
Built-in diagnostics
Online maintenance
This specific DS200ACNAG1ADD is a revised product; the original DS200ACNAG1 parent printed circuit board lacks its three significant revisions
Hardware Tips and Specifications
DS200ACNAG1ADD
The DS200ACNAG1ADD provides a connection point for ARCNET LAN communications within the Mark V system.
Signals travel between the main processor board (LDCC) and the turbine control operator interface via coaxial cables.
It’s a small circuit board with few components, including:
Four metal film resistors (R1 through R4).
Three capacitors (C1 through C3).
One diode.

Two factory-drilled holes with metal washers (GND1/GND2).
Two relays near the bottom edge, each with a relay diagram.
Three communication devices:
A vertical 6-pin terminal connector in the center.
Two right-angled, female BNC plugs at the top edge for LAN coaxial cables.
Due to its obsolete status, much hardware information comes from visual inspection and its part number.
