Overview / What Is Lowrance RJ45 to 5‑Pin Cable
The Lowrance RJ45 to 5‑Pin Cable is a specialized adapter cable that converts an RJ45 interface (typically used by modern Lowrance radar modules or Ethernet networks) to a 5‑pin male connector used by older marine devices. The cable measures 1.5 metres, and includes a molded boot for strain relief and waterproofing, making it ideal for marine environments.
This accessory solves common compatibility issues when integrating newer radar units or GPS modules into boats with legacy connectors. It’s categorized under Electronics & Navigation > Radar > Accessories, reflecting its role as an essential accessory in marine radar setups.
Key Applications and Use Cases
This adapter cable is widely used for:
- Connecting a newer Lowrance radar or sonar unit with RJ45 output to older engines or displays using 5‑pin input
- Integrating marine engines or NMEA networks aboard older vessels without replacing existing harnesses
- Simplifying upgrades while retaining legacy hardware investments
The cable is fitted with high quality shielding to protect against electromagnetic interference—critical when operating radar systems near engine electronics.
How to Install Lowrance RJ45 to 5‑Pin Cable
Installation is straightforward but must be done with precision to avoid signal issues. Here is a step‑by‑step guide on how to install the Lowrance RJ45 to 5‑Pin Cable:
- Locate the RJ45 port: This is usually on the back of the radar module or network hub.
- Insert the 5‑pin male connector: Firmly plug it into the legacy device or engine interface.
- Ensure boot is seated properly: The boot provides waterproofing—make sure it’s snug.
- Route the cable: Avoid sharp edges and heat sources; secure with tie‑wraps.
- Test signal: Power on systems and verify radar or network connectivity.

Compatibility and best Lowrance RJ45 to 5‑Pin Cable options
Not all adapter cables are made equal. Choosing the best Lowrance RJ45 to 5‑Pin Cable involves checking:
- High quality shielding
- Marine‑grade boot sealing
- Correct wiring pin‑outs matching your equipment
- Compatibility with both engine and radar/display units
The official Lowrance adapter meets all these requirements and is highly recommended for longevity and performance. Third‑party substitutes exist but often lack adequate moisture protection or correct pin wiring.
Troubleshooting Lowrance RJ45 to 5‑Pin Cable
Common issues may include no signal, intermittent connection, or network dropouts. Here’s how to address them:
- No signal: Ensure RJ45 and 5‑pin are fully seated and not bent pins.
- Intermittent radar or NMEA data: Check for damaged shielding or faulty boot seal letting water ingress.
- Corrosion at connector: Inspect pins regularly and dry connectors after exposure to spray or rain.
- Improper wiring: Confirm pin mapping matches both device requirements—consult manuals if unsure.
If problems persist, contact Lowrance support or refer to forums for detailed diagnostic flowcharts.
Maintenance Tips
Marine environments are unforgiving: salt spray, UV light, vibration, and moisture can degrade cable performance quickly. To maximize lifespan of the Lowrance RJ45 to 5‑Pin Cable, follow these maintenance tips:
- Rinse with fresh water: After every outing, rinse connectors to remove salt residue.
- Inspect boot seal: Check that the molded boot remains undamaged and intact.
- Dry thoroughly: Use compressed air or clean cloth to ensure no moisture lingers inside connectors.
- Store indoors: When not in use, stow cable away from UV exposure and extreme heat.
- Replace if frayed: Any visible cable damage or loose connectors warrant immediate replacement.
Proper care ensures the cable continues to deliver stable data connectivity between your radar displays and marine engines.

Detailed FAQ Section
How to install Lowrance RJ45 to 5‑Pin Cable correctly?
Installing the Lowrance RJ45 to 5‑Pin Cable correctly ensures strong signal integrity and waterproof sealing. First identify the RJ45 port on your radar module or network switch and the 5‑pin female port on your engine console or display. Insert the 5‑pin male connector until you feel a firm seating; ensure that the boot lines up straight to maintain waterproofing. Gently route the cable through a protected path, avoiding sharp edges and heat zones. Use cable ties to secure the run without overstressing the cable. Power on the equipment and verify that radar or NMEA data appears correctly. If the system fails to connect, unplug and reseat connectors, inspect for bent pins or moisture, and repeat the test. Proper installation avoids signal loss, intermittent connectivity, and ensures the boot does its job keeping water out.
