Raymarine has produced four communications protocols featuring SeaTalk as the root of the protocol's name. These include:
|Seatalk to nmea0183 and RS232|
Seatalk is the same as seatalk1. Ray just added the 1 after developing other more modern buses that they called seatalk2, seatalk hs and seatalk ng. Seatalk1 is ray's propriety version of nmea 0183. Seatalk1 is readily able to be converted to nmea 0183. Raymarine supply an accessory (Part #E85001) for converting Seatalk to NMEA 0183. Also, ShipModul's and Brookhouse's MUXes also convert Seatalk to NMEA 0183. Alternatively, if you have the ST60 repeater, you will find a NMEA output on the device which can connect directly to a SOB COM port.
Seatalk which is often referred to now, as seatalk1, is a multi-talker, multi-listener approach using serial data at low data rates (4.8Kbps). Compare that to nmea 0183 which is predominately a single talker, multi listener unless one uses a multiplexer.
The network used proprietary cables and connectors that were designed for the marine environment. The connectors are three pin molded and incorporate 1/8” automotive spades as mating elements.
SeaTalk uses three wires, connected in parallel to all devices on the bus:
- +12V Supply, red
- GND Supply, grey
- Data Serial Data, yellow
Unlike the Seatalk2 and Seatalk ng communications protocols, Seatalk communications protocol does not feature termination. Any Seatalk instruments and instruments or autopilot components featuring a 1st generation Seatalk interface which does not have a Seatalk ng interface (ex. ST40/60+ Instrument Displays, ST6001, etc.) can be interfaced to one another, in any order, using standard Seatalk cable. Seatalk cables can be joined using a Seatalk Junction Block, splices, marine grade terminal strips, or R55006 Seatalk Auxiliary Junction Boxes. This method of interfacing is referred to as a Seatalk bus. The Seatalk bus will typically be powered via a Seatalk Auxiliary Junction Box or via a Seatalk power cable which has been connected to one of the Seatalk devices.
Seatalk hs is raymarines high speed version of ethernet. It is plug and play.
By using SeaTalk hs networking, you can instantly transfer radar, chartplotter, fishfinder, thermal imaging and navigation functions. Configuring your system is a simple as determining which SeaTalk hs devices you'd like to have (chart, radar, sonar, video) and where you would like to see them.
|E series integrates nmea 0183, 2000 and seatalk hs|
Raymarine has network switches when working between 3 to 8 devices. They are.......
- The new HS-5 Seatalk hs Network Switch which has five ports
- Seatalk hs Network Switch which has 8 ports.
The following devices have Seatalk hs connections and can be easily connected together via the Seatalk hs network switch and Seatalk hs network cables:
- New e Series Multifunction Displays
- New c Series Multifunction Displays
- C Series Widescreen Multifunction Display
- E Series Widescreen Multifunction Displays
- G Series Navigation
- E Series Classic legacy Display
- T Series Thermal Cameras
- DSM30 and DSM300 Fishfinders
- Super HD and HD Digital Open Array Radar
- Digital Radome Radar
|Seatalk 2 network|
Provided you do not want to connect to NMEA2000, you can connect a Seatalkng system to Seatalk(1) using a suitable Seatalkng bridging product (such as an ST70 instrument) and adapter cables to connect the two systems.
This adapter enables an existing instrument network, using the SeaTalk2 5-pin connectors, to interface with a SeaTalk NG network.*Note that this cable cannot be used to connect a SeatalkNG network to the Seatalk2 port on the back of a Raymarine E-Series display. Use cable A06061 for that purpose.
|Older Style of Seatalk hs cable|
The new RayNet (F) to RayNet (F) network cable can be used to daisy-chain 2 adjacent RayNet devices together. It is also useful for joining two adjacent HS-5 Network Switches together on larger systems where multiple switches are necessary.
