Connect di-GPS® Mini 3L series GPS receiver to camera
Connect the DSLR camera and di-GPS® Mini 3L series GPS receiver as described
below.
1. Turn off the camera.
2. Remove the cap from the 10 pin remote terminal on the camera body.
3. Connect di-GPS® Mini 3L series GPS receiver to the camera’s 10 pin remote
terminal with 10 pin connector. Do not use any extension cord. For exact cable
connector of different models, please refer to Page 6 –Connector Cable of di-
GPS® Mini 3L series GPS receiver.
4. Switch the power mode to “On” or “Auto”.
5. Turn the camera on.
6. If di-GPS® Mini 3L series GPS receiver is properly connected, the camera will
display a blinking icon on the top control panel. It means the GPS receiver is
searching for a signal. The icon will stop blinking once signal has been
established and the receiver is ready for supplying the current position.
7. di-GPS® Mini 3L series GPS receiver will automatically detect the connection of
the camera. It cannot be turned on when the camera is not connected whatever
the power mode switch is set to "On" or "Auto". Both "On" and "Auto" mode is
only function when the camera is properly connected.
8. Each satellite broadcasts a digital message that contains two types of
information. One type is ephemeris data, which includes the assigned serial
number of the satellite, the status of the satellite (healthy or faulty), the current
date and time. The second type is almanac data and includes precise orbital
position of every satellite in the system.
At the initial stage, di-GPS® Mini 3L series GPS receiver needs all these data for
the position fixed. It usually takes a minute to few minutes to receive all data. An
open sky outdoor environment will enable faster acquisition process. It will take a
longer time at a weak signal environment. Once di-GPS® Mini 3L series GPS
receiver locks to the satellites, it will take a few seconds for reacquisition even at
weak signal environment.

GPS data are only recorded when GPS icon displayed on the top of LCD panel of DSLR
camera. Please make sure that GPS icon is displayed before shooting.
Last Fix Repeat (“LFR”)
di-GPS® Mini 3L series GPS receiver continuously reports the last fix when the GPS
signal is lost or the unit is out of the GPS coverage. With this new function, di-GPS®
Mini 3L series GPS receiver is able to provide the last fixed GPS data with current UTC
date/time to the DSLR camera even if there is no GPS signal, for example inside
buildings.
During initialization, di-GPS® Mini 3L series GPS receiver needs to obtain a first fix
before the LFR works properly. Once the GPS unit has a good position fix, the GPS will
continuously report the last fix with current UTC date/time if the GPS signal is lost or the
unit is out of GPS coverage. Once the new fix available, the GPS unit will immediately
report the updated GPS position to the camera.
After a power reset (power off….on), di-GPS® Mini 3L series GPS receiver reads the
last GPS position in internal memory. If there is no GPS data in the internal memory or
the internal clock is out of battery, di-GPS® Mini 3L series receiver will report no fix
available. The camera’s GPS icon will flash and no GPS data will be recorded. The
GPS unit will report the last recorded GPS data in the internal memory with current UTC
date/time after power reset. The internal Real Time Clock (RTC) is powered by the built-
in super capacitor. The operation time of built-in super capacitor is about 4 hours at
room temperature after the GPS unit turned off. Exhaustion of power of super capacitor
may cause incorrect RTC. Turn on the GPS unit and the super capacitor will be
charged in a few minutes. The last good fix will be recorded in each photo until a new
fix available.
Some models of the DSLR camera (Nikon D7000, D700, D3, D3S & D3X….) support
the function “Use GPS to set camera clock”. To prevent the incorrect time set, disable
the “Use GPS to set camera clock” function under the GPS menu or turn on the GPS
unit and wait for new fix before turn on the camera.
