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.

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.
