Determining An Installation Location - Garmin GBT 10 Bennett Trim Tab Adapter Installation and Configuration Installation And Configuration Manual

Determining an Installation Location

When you are selecting a location to install the GBT 10 adapter, consider the following:
• During installation, you connect the GBT 10 adapter to the Bennett TPI (or directly to the
Bennett trim tab sensors), and to the NMEA 2000 network. Therefore:
◦ Choose a location that is within 173 in. (4.4 m) of the Bennett TPI (or the Bennett trim
tab sensors) to avoid splicing bare wires.
◦ Choose a location between the NMEA 2000 backbone and the Bennett TPI (or the
Bennett trim tab sensors).
◦ If you cannot connect the adapter directly to the NMEA 2000 network, add a drop cable.
See page 3 for more information.
• The adapter is IEC 60529 IPX7 waterproof, and can be submerged up to 30 minutes at 1
meter. Do not install the adapter in a location where it will be submerged regularly, though
the location can be subject to wash-down.
• You can use cable ties (not included) to secure the adapter to an existing structure on your
boat.
• You can use mounted-head cable ties (not included) and screws (not included) to secure the
adapter to a bulkhead or other suitable surface on your boat.
• Install the adapter at least 2 in. (5 cm) from a magnetic compass to prevent electromagnetic
interference, which can cause inaccurate compass readings.
Wiring the GBT 10 Adapter
Connect the GBT 10 adapter either to the Bennett TPI or to the Bennett trim tab sensors directly
using the bare wires on the wiring harness.
Wiring the GBT 10 Adapter to the Bennett
Trim Tab Display
You can wire the GBT 10 adapter directly to the Bennett
TPI. Do not remove any wires from the back of the
Bennett TPI, and wire the GBT 10 adapter to the TPI
according to the following table. Use only the wires listed
for the GBT 10 adapter. Cut and tape any unused wires.
*When wiring the GBT 10 adapter to the Bennett TPI, it is important that you do not connect
wires to the RED and GRN connections farthest from the SHLD connection. Connecting the
GBT 10 adapter wires to the connections farthest from the SHLD connection will interfere with
the operation of the Bennett TPI.
