Lowrance 000-0127-49 PC-30-RS422 — Power & NMEA 0183 Cable
The Lowrance PC-30-RS422 is the OEM power and data cable for compatible Lowrance chartplotter and fishfinder displays. It provides 12V DC power to the display and includes RS-422 NMEA 0183 wiring for connecting external NMEA 0183 devices — such as autopilots, VHF radios, GPS sensors, and AIS receivers — directly to the display's data port. This is the correct replacement cable when the original has been lost or damaged on a PC-30-RS422-equipped display.

Installation Notes
- Confirm your specific Lowrance display model calls for the PC-30-RS422 cable — not all Lowrance displays use this cable designation; some models use a 2-wire power-only cable or a different data connector
- Fuse the power lead close to the battery or distribution panel; Lowrance typically specifies a 3A or 5A fuse — confirm in your display’s installation manual
- RS-422 NMEA 0183 is a differential signal — observe TX+/TX− and RX+/RX− polarity when connecting to external devices
- Keep data wiring away from high-current DC cables and engine wiring to prevent signal interference
Parts Desk Insights
Best Use Case: This is the correct cable when you need to replace the original power/data lead on a Lowrance display that uses the PC-30-RS422 connector — most commonly on HDS Gen 2 and Gen 3 units and some Elite Ti installations. It’s also the right choice when adding NMEA 0183 connectivity to an existing display that was previously powered with a basic power-only cable, provided the display has a PC-30-RS422 port.
Common Issues: The most common ordering mistake is selecting this cable for a display that actually requires a different power cable designation. Always check the installation manual for your specific model and serial number before ordering — Lowrance uses several different power cable types across the HDS, Elite, and Hook product lines. If the display powers on but NMEA 0183 data isn’t communicating, confirm RS-422 TX/RX polarity at the connected device and verify the external device is configured for RS-422 (not RS-232) input.
