Power output
If the receiver is being supplied with power from an external source,
power is automatically output on Port 1. The output voltage is
approximately 0.5 V less than the input voltage. Port 1 outputs a
maximum voltage of 20 V, even if the input voltage is higher.
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.
