Garmin BlueNet Network with an OnDeck GTB 10 hub and Legacy Garmin Marine Network Devices
If your Garmin BlueNet™ network includes an OnDeck™ GTB 10 hub and legacy Garmin® Marine Network devices, you must connect the OnDeck GTB 10 hub directly to a Garmin BlueNet chartplotter or Garmin BlueNet 20 switch for proper functionality.
You should use the appropriate Garmin BlueNet network to RJ45 adapter cable (010-12531-01) to connect an OnDeck GTB 10 hub directly to a Garmin BlueNet chartplotter or Garmin BlueNet 20 switch.
This is a notable exception to the common requirement for connecting legacy Garmin Marine Network devices through a Garmin BlueNet 30 gateway. Connecting an OnDeck GTB 10 hub to a Garmin BlueNet network through a Garmin BlueNet 30 gateway will result in network performance issues.

Legacy Garmin Marine Network devices |
If you have more than two legacy Garmin Marine Network devices, these devices must connect to one another or to a GMS™ 10 switch. If you have only two legacy Garmin Marine Network devices, you can connect them both to the Garmin BlueNet 30 gateway without first connecting them to one another. |

You must not use this cable to connect other legacy Garmin Marine Network devices directly to a Garmin BlueNet device. Other than the OnDeck GTB 10 hub, you must connect other compatible legacy Garmin Marine Network devices to a Garmin BlueNet network using a Garmin BlueNet 30 gateway. |
