Choose accessories by connection or purpose
NMEA 2000 networks: Humminbird starter kits, 0.5 m and 10 m drop cables, T-connectors, power T-cables and male/female terminators are listed separately. A functioning network requires the correct backbone layout, power and termination according to the equipment instructions.
Ethernet networking: Humminbird AS ETH 5PGL is listed as a five-port Ethernet switch; AS ECX 30E is a 9.1 m extension cable and AS EC QDE is an adapter for specified HELIX models. Check the supported device and connector generation.
GPS and display connections: Humminbird AS GPS adapter cable, NMEA 0183 splitter and APEX HDMI input/output cables serve different connections. HDMI IN and OUT cables are not interchangeable merely because they share the HDMI name.
Protective covers: select by the exact screen family and size, such as HELIX 9/10, SOLIX 10/12 or APEX 16.
Compatibility checklist
Compare the manufacturer part number, display model, port type, cable length and installation requirements. NMEA 0183, NMEA 2000 and Ethernet are not automatically interchangeable; an adapter may still require a supported device. These examples are from ACTIVE Shopify listings, not independent compatibility tests.
