5. Connect an external power source to Port 2 on the receiver.
Note – External rover radios must have their own power source
because the internal Lithium-Ion batteries do not supply enough
voltage. Alternatively, supply external power to port 2 of the
5700 receiver, and enable power out on port 3.
Base radios must have their own power source because of their
high power consumption
Alternatively, you can apply external power directly to the radio,
if it supports it.
You can use a 10 Ah battery, a 6 Ah battery, or camcorder
batteries. The choice of power supply depends on the
application, and whether you are using the radio as a reference
or rover radio. For more information about the power
capabilities of the 5700 receiver, see Power Supply, page 42.
6. Configure the external radio using the Trimble Survey Controller
software. Alternatively, you can configure a TRIMMARK 3 radio
using the WinFlash software or the configuration software
supplied with the radio.
For more information, refer to the Trimble Survey Controller User
Guide or the appropriate Help.
7. Set up any other equipment as required, depending on whether
you are using the radio as a reference or a rover radio.

Cellular modems
You can use a cellular modem instead of a radio as your data
communications link. Cellular modems and other radio links can be
used to extend the limits of your surveys.
To connect a cellular modem to a 5700 receiver, you need the following:
• 5700 receiver
• A custom-designed cellular modem, or a cellphone that can
transmit and receive data
