Settings / NMEA & AIS / WiFi



The following settings can be used to connect your device to NMEA/AIS over WiFi. Before adjusting them, first ensure this device and your source of NMEA/AIS data are connected to the same network.


Below are configuration setting for devices from a number of vendors.

Digital Yacht: iAIS

Digital Yacht devices support both TCP and UDP. They recommend UDP because (1) the simpler configuration, and (2) UDP allows you to have multiple iPads and other devices access it (TCP only allows 1 device at a time).

iAIS does not provide GPS information unless it has been connected to another NMEA data feed from your vessel's other instruments. Because of this, you may want to enable Only Use AIS Targets so that SEAiq will use the internal device GPS for position.

Vesper Marine: XB-8000

Below are the settings for the Vesper Marine XB-8000 AIS transponder. It is possible to change the settings for the Host; if you have done so, you will want to use your new setting instead.

Navicom Dynamics PPUs

Please refer to Navicom Dynamics Settings for complete instructions on configuring SEAiq Pilot with Navicom Dynamics PPUs.


Trelleborg CAT ROT v2 and CAT 1

SEAiq supports CAT ROT v2 both with and without the CAT 1 device. For users with the original CAT ROT device, see the section below. For users with CAT ROTv2 with firmware prior to 1.2.0 or that is used without a CAT 1, all that is required is the following:

If your device has a firewall, you will need to disable it or open this port in the firewall.

For users with both a CAT ROTv2 and CAT 1 device and with firmware 1.2.0 or later, an additional configuration step is required. This is because data from CAT 1 no longer arrives from the same feed as CAT ROT. The CAT 1 now uses a separate port. Use the following settings in Extra NMEA in addition to the settings above. You can determine the firmware version by viewing the SEAiq vertical status bar while connected to the device.

If your device has a firewall, you will need to disable it or open this port in the firewall.

In addition to standard position and AIS data, SEAiq will also display in the status bar battery status, charging status, and firmware version for both devices. Battery status is shown using standard bars. Critical indicates the device will turn off automatically and this value may possibly never be seen. Charging status is indicated as (+) if the battery is currently accepting a charge.

You can enable Settings / Status Bar / Show GPS Diagnostics and/or Settings / Status Bar / Show GPS Satellites to see detailed information about GPS.

Trelleborg E-Sea FIX CAT ROT (Version 1)

SEAiq supports all 4 configurations of this product. UDP is recommended because it is easier to configure (no IP address is required) and will recover more rapidly if the WiFi signal is temporarily lost.

Note that some CAT ROT devices do not support DHCP IP address assignment and so may require you to configure your iPad WiFi's IP address manually. Contact the manufacturer for more information.

UDP mode supports 2 ports. 17608 uses standard AIS messaging. 17609 provides separate high-resolution heading and ROT data:

TCP mode also supports 2 ports. 5000 uses standard AIS messaging. 5001 provides separate high-resolution heading and ROT data. The IP address of the CAT ROT must be provided. Normally, it will be

Trelleborg CAT II and CAT III

There are two different configurations for these, which can be used if you want to connect 2 different client devices. Because of the networking configuration used, at most 2 clients can connect at the same time.

These devices do not support DHCP IP address assignment. This means they require you to configure your iPad WiFi's IP address manually. Please carefully follow the instructions below.

Configuration 1

The configuration below is the same as Trelleborg CAT ROT (v2,v3,v4) preset, so you can select that preset for this configuration.

Manually set your device WiFi to these settings: On iPad/iPhone, follow these steps:
Configuration 2
Manually set your device WiFi to these settings (refer to instructions in Configure 1, but use the IP address below):

Pilots TECH AIS Pilot Plug WiFi

SEAiq supports the Pilots TECH AIS Pilot Plug WiFi. Use the configuration below. Older units may use port 60000 instead of 8888.


SEAiq supports the GlobPilot WiFiAis and WiFiAisGPS. Use the configuration below.


SEAiq supports the PILOT CENKIN® AIS Pilot Plug. Use the configuration below.


SEAiq supports the CENKIN CP4 AIS pilot plug. Use the configuration below.

ShipModul MiniPlex-2Wi

SEAiq supports the ShipModul MiniPlex-2Wi. Normally, you can use the configuration below. The port is always 10110. The IP address will be used when the device is operating as an "access point". However, when used in "infrastructure mode", the IP address may be different; please see the device's documentation for more information.

Trimble SPS585 GNSS PPU

A pair of Trimble SPS585 GNSS receivers offer a combination of independent GNSS positioning and precise rate-of-turn with independent heading data. The primary SPS585 can receive corrections from a Virtual Reference Station (VRS) or a single GNSS base station (IBSS), when connected to the Internet, to deliver centimetre accurate 3D positions. If there is no VRS or IBSS available then the Trimble Centerpoint RTX subscription service can be used on the primary receiver Trimble RTX is a near global satellite service better than 10 centimetre accuracy without a GNSS base station. The receiver will also operate with SBAS corrections (such as WAAS, EGNOS etc) if available.

Typical Connection Settings: WiFi over TCP (Check details in the latest technical documentation from Trimble. Bluetooth is also available from the SPS585 receiver.

AD Navigation PPUs

Please refer to AD Navigation Settings for complete instructions on configuring SEAiq Pilot with AD Navigation PPUs.

TRENZ Pilot Plug

SEAiq supports the TRENZ Pilot Plug. Support includes reporting battery level and other detailed diagnostics reported by the devices.


SEAiq supports the PilotMate devices. Use the configuration in your documentation. When connected to the PilotMate device, it will be recognized as such and a diagnostic panel will appear in the status bar.
