Internal Radio Setup
You can configure the 5800 receiver’s optional internal radio using
any of the following:
• the GPS Configurator software
• the WinFLASH software
• the Trimble Survey Controller™ software
For more information, refer to the GPS Configurator Help, the
WinFLASH Help, or the Trimble Survey Controller User Guide.
By default, the internal radio has only a few “test” frequencies
installed at the factory. Use WinFLASH to program your licensed
frequencies prior to using the receiver. For more information, see
Adding Frequencies for the Internal Radio, page 161.
12.5.2 Cellular Modems and External Radios
You can use a cellular modem or external radio instead of the internal
radio as your data communications link.
To connect a cellular modem to a 5800 receiver you need the
following:
• 5800 Receiver
• A cellular modem, or a cellphone that can transmit and receive
data
• Serial (cellphone to DB9) cable (supplied with the cellular
modem or phone)
Note – For more information, refer to the document Using
Cellular and CDPD Modems for RTK, which is available from
the Trimble website.
• Port 2 of the 5800 supports full RS-232 protocol, and should
function properly with most cellular phone cables. Some
cellular units may require custom cabling.
