More Information

Overview Manuals Network Topology ARCPL Signals Node Integration Link Boundaries

Features:

  • Terminates two coaxial cables on an EX2000 ARCNET data link.
  • Connects controller, operator, protection, and Mark V network nodes.
  • Transfers two signal channels and board power through the ARCPL interface.
DS200ACNAG1A gives the EX2000 communication hardware a defined coaxial entry and exit point without placing field cabling directly on the controller card.

ARCNET token passing permits only the node holding the token to transmit, while loss of the token triggers network reconfiguration among participating nodes.

Cable length, 93-ohm end termination, and the paired transmit/receive conductors all belong to the link design and must remain consistent across the connected nodes.

The General Electric DS200ACNAG1A ARCNET Connect Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Network Topology

  • Daisy Chain: ARCNET nodes are connected through a continuous coaxial cable path.
  • Token Passing: A node transmits after receiving the network token.
  • Reconfiguration: Nodes rebuild the token sequence if token reception is lost.
  • End Termination: Both ends of the coaxial chain use 93-ohm termination.

ARCPL Signals

  • Channel A: TXA- and TXA+ carry the first differential transmit/receive path.
  • Channel B: TXB- and TXB+ form the second differential network path.
  • Board Power: P5 and DCOM provide +5 VDC and digital common through ARCPL.
  • Selectable Lines: TXA and TXB support the controller's isolated DLAN or RS-422 selection.

Node Integration

  • Main Controller: ACNA couples the EX2000 controller to the shared data link.
  • Operator Station: IOS traffic reaches the excitation system through ARCNET.
  • Protection Module: Protection data uses the same network connection architecture.
  • Mark V Interface: The link can extend to a SPEEDTRONIC Mark V turbine-control panel.

Link Boundaries

  • Physical Role: ACNA terminates cables but does not replace the ARCNET controller circuitry.
  • Controller Pairing: The board connects to SLCC or LDCC through the ARCPL cable.
  • Network Rate: The DLAN+ physical layer operates at 2.5 MBaud.
  • Cable Limit: The overall ARCNET path is limited by the system cable-length design.
Description
Within the GE EX2000 excitation platform, General Electric DS200ACNAG1A serves as the ARCNET connect board. It forms the physical network junction among the main controller, Intelligent Operator Station, protection module, and a connected Mark V turbine-control panel.

General Electric DS200ACNAG1A terminates two coaxial cables, allowing the ARCNET/DLAN+ network to continue as a daisy-chained token-passing link. The network uses baseband communication at 2.5 MBaud and requires termination at both ends of the cable run.

The eight-pin ARCPL path on General Electric DS200ACNAG1A carries two differential transmit/receive channel pairs together with +5 VDC and digital common. Additional TXA and TXB conductors support the isolated DLAN or RS-422 selection provided by the associated controller hardware.

Because General Electric DS200ACNAG1A is the cable termination point rather than the ARCNET controller itself, the attached SLCC or LDCC hardware supplies the active communications interface. Coax routing, end termination, and ARCPL pin alignment define the usable link.

Technical notes
General Electric DS200ACNAG1A terminates two EX2000 ARCNET coaxial links and connects them to SLCC or LDCC through ARCPL.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which devices share the network through General Electric DS200ACNAG1A?
General Electric DS200ACNAG1A connects the EX2000 main controller, IOS, protection module, and Mark V panel on the ARCNET data link.
Why does General Electric DS200ACNAG1A have two coaxial terminations?
The two coaxial connections let General Electric DS200ACNAG1A sit in the daisy-chained ARCNET path between network nodes.
What is carried on the ARCPL connector of General Electric DS200ACNAG1A?
On General Electric DS200ACNAG1A, ARCPL carries channel A and B signal pairs, +5 VDC, digital common, and selectable TXA/TXB lines.
Is General Electric DS200ACNAG1A the ARCNET controller chip board?
No. General Electric DS200ACNAG1A is the terminal connection board; the associated SLCC or LDCC provides the active ARCNET interface.
How should an ARCNET run using General Electric DS200ACNAG1A be terminated?
A General Electric DS200ACNAG1A network uses 93-ohm termination at both ends of the coaxial daisy chain.
What must be verified before fitting General Electric DS200ACNAG1A?
Confirm the EX2000 node location, two coax routes, end-of-line termination, and the eight-pin ARCPL connection for General Electric DS200ACNAG1A.
