Technical Specification

Here are the technical specifications for the Raymarine R52131 SeaTalk-NG to SeaTalk 5-Way Converter Connector:

General:

• Part Number: R52131
• Function: Translates data between legacy Raymarine SeaTalk¹ (also known as SeaTalk 1) protocol and modern SeaTalk^(ng) (NMEA 2000 compatible) protocol.
• Role: Acts as a bridge, allowing older SeaTalk¹ instruments to communicate with SeaTalk^(ng) devices.

Connectivity:

• SeaTalk^(ng) Backbone Ports: 2 x Blue SeaTalk^(ng) backbone connectors (for connection to the main SeaTalk^(ng) backbone cable).
• SeaTalk^(ng) Spur Ports: 3 x White SeaTalk^(ng) spur connectors (for connecting individual SeaTalk^(ng) devices like displays, sensors, or other spurs).
• SeaTalk¹ Port: 1 x Yellow SeaTalk¹ connector (for connecting a single SeaTalk¹ device or a daisy-chain of up to 5 SeaTalk¹ devices).
  • Note: The SeaTalk¹ devices connected to this port form a single segment that is powered by the converter. This segment should not be connected to another powered SeaTalk¹ backbone.

Electrical:

• Supply Voltage: 12 V DC (Volts Direct Current) – powered directly from the SeaTalk^(ng) backbone.
• Operating Voltage Range: 9 V DC to 16 V DC
• Current Consumption: Typically low, around 50 mA (milliamperes) nominal (excluding power supplied to SeaTalk¹ devices). The converter supplies power to the connected SeaTalk¹ devices.
• SeaTalk^(ng) LEN (Load Equivalency Number): Typically 1 (meaning it draws 50 mA from the NMEA 2000 / SeaTalk^(ng) network).

Data Conversion:

• Supported SeaTalk¹ Data: Converts a wide range of standard SeaTalk¹ sentences (e.g., depth, speed, wind, heading, GPS position, navigation data, rudder angle) to equivalent NMEA 2000 PGNs (Parameter Group Numbers) and vice-versa.
• Supported NMEA 2000 PGNs: Converts relevant PGNs to SeaTalk¹ sentences and vice-versa to ensure data compatibility.

Physical & Environmental:

• Dimensions (W x H x D): Approx. 136 mm (5.35 in) x 88 mm (3.46 in) x 32 mm (1.26 in)
• Weight: Approx. 0.15 kg (0.33 lbs)
• Mounting: Designed for internal mounting (e.g., behind a panel, in a dry space).
• Construction: Durable plastic casing.
• Ingress Protection (IP) Rating: Typically IPX6 or similar for splash resistance, but generally recommended for internal mounting.
• Operating Temperature: -15°C to +55°C (5°F to 131°F)
• Storage Temperature: -25°C to +70°C (-13°F to 158°F)
• Humidity: 95% at 35°C (non-condensing)
