Introducing SP60 as Local Base
Possible Local Base
Configurations
The SP60 can be used as a local base, delivering its
corrections through one of the following devices:
• Long-Range Bluetooth: For baselines less than 800
meters (0.5 mile), the local base will be able to deliver its
corrections to a rover over a long-range Bluetooth
connection.
• UHF radio (optional accessory): The local base may be
fitted with an internal radio module (internal UHF radio,
2 W TRx), or an external radio delivering more RF power.
For more information on the internal radio module, see
Using the UHF Kit Option on page 23 .
Internal vs.
External Power
Source
Consider the following before setting up a local base:
• If the base is left unattended for the whole day, you may
want to power it from an external power source that will
provide enough power for your work day.
In this case, you may use the Field Power kit (see
Field
Power Kit P/N 94335 on page 3 ) to connect the receiver
to an external 12-Volt battery. See diagram in which [1] is
cable P/N 95715 and [2] is cable P/N 83223-02.
NOTE: If you need to change the fuse on cable P/N
83223-02, please use the same type of fuse as the one
originally provided (15 A @32 V). This is mandatory.
• If you intend to work close enough to the base, or someone
is in charge of keeping the base running throughout the
day, you may decide to power the base from its internal
battery.
For a day’s work, you may need two batteries: A fresh one
inserted in the receiver at the beginning of the day, and
the second one may be needed sometime before the end
of the day.
