Brief Product Description

The Woodward 5417‑557 DPC‑1 is a dedicated galvanically‑isolated RS‑232 configuration communication cable, designed to connect a PC to Woodward legacy genset controllers and protection relays. It features a DB‑9 RS‑232 PC‑side connector and a special RJ45 connector for Woodward DPC‑enabled hardware. Built‑in electrical isolation protects both the computer and industrial control unit against ground‑loop damage and high‑voltage transients in noisy power‑plant environments. This shielded serial cable serves as the essential local service link for parameter setup, firmware download, live monitoring and fault diagnostics. As an end‑of‑life accessory spare part, it is available as fully‑tested surplus and refurbished units for maintenance and retrofit of existing Woodward power‑generation control installations.

Core Product Functions

• Point‑to‑point serial communication link between PC workstation and Woodward DPC‑compatible control hardware
• Galvanic isolation eliminates ground‑loop interference and safeguards PC and controller from voltage surges
• Support controller parameter uploading / downloading, on‑site commissioning and setpoint tuning
• Real‑time live data monitoring, fault log reading and firmware upgrade for connected Woodward devices
• Shielded cable construction delivers stable serial communication under high‑EMI industrial and marine cabinet conditions
• DB‑9 female RS‑232 interface for PC side, proprietary RJ45 plug for Woodward controller DPC service port
• Works with Woodward PC‑based configuration software for genset protection and generator control units
• No network switch or hub required; direct peer‑to‑peer connection simplifies field service work

• Wide operating temperature range for reliable usage inside power‑plant, engine‑room and industrial control cabinets

Application Scenarios

• Commissioning, configuration and troubleshooting for Woodward easYgen series generator controllers
• Parameter setup and fault diagnosis for MFR‑series multifunction generator protection relays
• Service access for Woodward GCP and AMG power management control devices
• On‑site maintenance, firmware update and log retrieval for marine and industrial genset control panels
• Captive power plant, combined‑cycle auxiliary generator control system field service work
• Spare replacement configuration cable for maintenance, troubleshooting and retrofit of legacy Woodward control systems

FAQ (Frequently Asked Questions)

• Q: PC cannot establish communication with Woodward controller using 5417‑557?
  A: Verify physical connector seating, confirm correct COM port selection, match software baud‑rate parameters, check controller power‑on status and avoid using standard Ethernet RJ45 cables as replacement.
• Q: Can I use a regular standard RJ45‑to‑DB9 serial cable to substitute 5417‑557 DPC‑1?
  A: No. It uses proprietary pin assignment plus built‑in galvanic isolation; ordinary serial or network cables will fail communication and risk hardware damage.
• Q: Does Woodward 5417‑557 support Ethernet TCP/IP network communication?
  A: No. The RJ45 connector is for DPC serial signal only, not Ethernet; it works exclusively for point‑to‑point RS‑232 service connection.
• Q: Is this cable compatible with third‑party PLC or non‑DPC Woodward control products?
  A: It is only intended for Woodward DPC‑port‑equipped devices; it will not function with controllers lacking DPC service interface.
• Q: Is Woodward 5417‑557 available for brand‑new generator project commissioning?
  A: This legacy DPC‑1 configuration cable has reached end‑of‑life. Only surplus and fully‑tested refurbished units are offered for existing‑site maintenance and retrofit tasks.
