Introduction
Thank you for purchasing the N1 di-GPS Receiver. The N1 di-GPS (digital
images GPS) is specially designed for DSLR (Digital Single-lens reflex)
camera. It provides real time position (latitude, longitude, elevation) and the
precise time (UTM time) information to your DSLR camera. It records the
locations to each digital image file so that you would never forget the exact
location where you took the pictures.
N1 di-GPS allows you to save your present location data to your digital image
file. Its State-Of-The-Art technology provides extremely fast TTFF (Time-To-
First-Fix), unrivaled high sensitive and superior performance at virtually any
outdoor environments. The N1 di-GPS can work in a place where GPS was
not possible before, in the woods, under very heavy foliage, canyon, terrain
obstructions, in cities with densely populated high-rise buildings and even
inside a train or a car, with no external antenna required. It is designed to
meet the rigorous demands of today's digital photographers.

The N1 di-GPS receiver provides two mounting accessories – aluminum
mounting bracket and pouch.
Aluminum mounting bracket can be fixed at the bottom of the DSLR camera
body. Pouch can be attached to your camera strap.
Connect a N1 di-GPS
Connect the DSLR camera and N1 di-GPS as described below.
1. Turn off the camera.
2. Remove the Cap from the 10 pins remote terminal on the camera body.
3. Place the Cap into the Cap Holder on the N1 di-GPS body.
4. Connect the N1 di-GPS to the camera’s 10 pins remote terminal with
10 pins connector. Do not use any extension cord. The 10-pins
connector must align to the mark on the camera body and tighten the
locking nut. The N1 di-GPS will detect the connection of the camera.
5. Select the power mode “On” / “Auto”. If the power switch to “On”, the
N1 di-GPS will switch on.
6. Turn the camera on.
7. If the N1 di-GPS is properly connected, the camera will display a
blinking icon in the top control panel as the GPS receiver is searching
for a signal. The icon will stop blinking once a signal has been
established and the receiver is ready to supply the current position.
N1 di-GPS 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 only function when
the camera is properly connected.
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 initialize stage, N1-di-GPS 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 N1 di-GPS locked to the
satellites, it will take a few seconds for reacquisition even at weak signal
environment.
