Connections
| Connection | Specification |
|---|---|
| AIS Antenna Connector | Standard BNC female 50 Ohm connector. Requires an active VHF antenna splitter (e.g., A015-RX) if sharing a single VHF antenna between the A027 and a VHF voice radio. |
| GPS Antenna Connector | Standard SMA female 50 Ohm connector for connecting an active GPS antenna. |
| SeaTalk Input Connector | 3-pin terminals for connection to the SeaTalk bus. Must be wired correctly to avoid damage to the A027 or other SeaTalk devices. The A027 runs on 12.0V DC and is powered through the SeaTalk interface, improving supply stability and signal reception. |
| LED Indicators | Three LEDs showing power, AIS status, and GPS status. |
| NMEA 0183 Output Connector | Can connect to AIS-compatible equipment (wind, depth, heading sensors) via NMEA inputs. Outputs NMEA 0183 messages simultaneously over WiFi, USB, and NMEA 0183. |
| USB Connector | Micro-USB connector outputs NMEA messages and supports configuration via GUI software. Can connect directly to a PC or other mobile devices using the supplied cable. |

FAQ – How to connect NMEA0183 RS422 to older RS232 devices.
This product uses the NMEA 0183-RS422 protocol (differential signal), however some older chart plotters or instruments may use the older NMEA-RS232 protocol (single-ended signal).
To ensure A027 compatibility with any older NMEA0183 devices, check if your device uses NMEA0183 RS422 or RS232
- NMEA0183 RS422 devices’ wiring is compatible ‘out of the box’
- NMEA0183 RS232 will require a Protocol Bridge (AS03) to connect your wiring
Connecting the A027 to an older (RS232) instrument or chart plotter is not a problem, simply order the AS03 Protocol Bridge. Our AS03 Protocol Bridge connects NMEA-RS232 wiring to MNEA0183-RS422 and vice versa, using a simple ‘plug ‘n’ play’ connection, with no setup or configuration needed.
You will probably need an AS03 if you are connecting to an older Garmin, Raymarine or Standard Horizon device. The easiest way to check is to look at the input/output connections on the device that you will connect the multiplexer to. If the input/output connections on your device (chart plotter, depth reader, etc.) have a TX, RX or GND connection, you will need to use a protocol bridge.
If in doubt contact us for advice.
