Network Architecture and ARCNET Protocol
The GE DS200ACNAG1A DS200ACNAG1ADD implements the ANSI 878.1 ARCNET standard. This protocol provides deterministic token-passing access for real-time control. The board operates at a fixed data rate of 2.5 Mbps. It supports up to 255 nodes on a single network. The GE DS200ACNAG1A DS200ACNAG1ADD uses RS-485 differential signaling for noise immunity. Maximum cable length reaches 610 meters per network segment.
Physical Layer and Cable Options
This ARCNET board offers two physical connection options for flexibility. BNC connectors support coaxial cable for long-distance runs. RJ11 connectors support twisted-pair cable for cabinet wiring. The DS200ACNAG1A DS200ACNAG1ADD includes an internal 120 Ω termination resistor. A DIP switch enables or disables termination as needed. Shielded twisted-pair cable (Belden 9841) provides the best noise rejection.
Node Configuration and Addressing
An 8-position DIP switch sets the unique node address for this board. Valid addresses range from 1 to 255 for network identification. The GE DS200ACNAG1A DS200ACNAG1ADD automatically detects network reconfiguration events. It participates in token passing to access the communication medium. Three status LEDs show power, transmit activity, and receive activity. The green PWR LED lights when the board receives proper supply voltage.
Physical Dimensions and Installation Guidelines
The GE DS200ACNAG1A DS200ACNAG1ADD weighs 0.420 kilograms for secure mounting. Its height measures 250mm, width 120mm, and depth 30mm. Install this board in the communication slot of AC2000 drives. The board consumes 2.5 watts from the internal power supply. It operates reliably from 0°C to +50°C ambient temperature. Use proper ESD handling procedures during installation.
Energy Storage and Electrical Characteristics
The DS200ACNAG1A DS200ACNAG1ADD includes a 47 µF capacitor for power filtering. This capacitor stabilizes the internal 5 V DC supply rail. It also filters noise from the ARCNET transceiver circuits. The capacitor discharges within 15 seconds after removing input power. Wait 30 seconds before servicing the GE DS200ACNAG1A DS200ACNAG1ADD for safety. No battery is present on this ARCNET communication board.
