You can use GPS Configurator or Trimble Survey Controller to enable
power output on Port 3. Port 3 can be enabled for power output
regardless of whether power is supplied internally or externally.
On Port 3, the output voltage is approximately 0.5 V less than the
input voltage. For example, if power is being supplied from the
internal Lithium ion batteries, the maximum battery voltage is 8.4 V,
so the maximum output voltage is 7.9 V.
Note – When you start a survey using Trimble Survey Controller, and
you are using an external radio, the software automatically enables
power output on Port 3.

A receiver’s firmware is the program inside the receiver that makes the
receiver run and controls the hardware. When you need to upgrade the
firmware for your Trimble R7 receiver, Trimble recommends that you
use WinFlash. For more information, see WinFlash Software, page 71.
