di-GPS® Eco ProSumer

Introduction

Thank you for purchasing di-GPS® Eco ProSumer series GPS receiver (digital images GPS).

The di-GPS® Eco ProSumer series GPS receiver (thereafter “Eco Pro-S GPS”) is specially designed for a DSLR (Digital Single-lens Reflex) camera. It provides real time position (latitude, longitude, elevation) and the precise time (UTC time) information to your DSLR camera. It records the locations to each digital image file so that you will never forget the exact location where you took the pictures.

Eco Pro-S GPS has built with the latest third generation MTK MT3339 ultra low power consumption GPS engine. It supports up to 66 channels of satellite tracking with -165dBm sensitivity. Eco Pro-S GPS repeats the last fixed position(1) when no GPS signal is available or the unit is out of GPS coverage with real UTC date/time.

Eco Pro-S 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 sensitivity and superior performance in virtually any outdoor environment. Eco Pro-S GPS receiver can work in a place where GPS was not possible before: in the woods, under very heavy foliage, canyons, 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.

Warnings and Precautions

Part Names of Eco Pro-S GPS

The di-GPS Eco Pro-S GPS unit is shown. Key components are labeled:

• A: Power Mode Switch
• B: Status LED
• C: Connector to DSLR camera
• D: Shutter release socket (2.5mm)

Connecting Eco Pro-S GPS to Camera

Directly connect the Eco Pro-S GPS to the accessory terminal of the DSLR camera body.

Description of how the strap should be attached.

A supplied remote control accessory can be connected to the 2.5mm remote terminal of Eco Pro-S GPS for remote shutter release.

NOTE

• Eco Pro-S GPS cannot be turned on when the camera is not connected.
• Please refer to the user guide of your DSLR for more information on taking photographs with a GPS receiver.
• Be sure to turn off your camera before disconnecting Eco Pro-S GPS. Do not connect or disconnect Eco Pro-S GPS while the camera is on. Failure to observe this precaution could cause a malfunction of the camera.
• Do not carry the camera by the Eco Pro-S GPS or subject the camera or the unit to physical shocks while the unit is connected. Failure to observe this precaution could result in physical damage of the unit or the camera's GPS terminals.
• Replace the caps on the camera when the terminals are not in use.

Recording GPS Data (1)

Connect the DSLR camera and Eco Pro-S GPS as described below.

1. Turn off the camera.
2. Remove the cap from the accessory terminal on the camera body.
3. Attach the Eco Pro-S GPS directly to the accessory terminal on camera. Do not use any extension cord.
4. Switch the power mode to “On” or “Auto”.
5. Turn the camera on.
6. If Eco Pro-S GPS is properly connected, the camera will display a blinking icon on the top control panel. This indicates the Eco Pro-S GPS is searching for a signal. The icon will stop blinking once a signal has been established and the Eco Pro-S GPS is ready for supplying the current position.
7. Eco Pro-S GPS will automatically detect the connection of the camera. It cannot be turned on when the camera is not connected, regardless of the power mode switch setting ("On" or "Auto"). Both "On" and "Auto" modes only function when the camera is properly connected.

Recording GPS Data (II)

Each satellite broadcasts a digital message containing 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), and current date and time. The second type is almanac data, which includes the precise orbital position of every satellite in the system.

At the initial stage, the Eco Pro-S GPS needs all this data for position fixing. This usually takes one to few minutes to receive all data. An open sky outdoor environment will enable a faster acquisition process. It will take longer at a weak signal environment. Once the Eco Pro-S GPS locks onto satellites, it will take a few seconds for reacquisition, even in a weak signal environment.

The EASY™ function is an Embedded Assist System for quick positioning. The Eco Pro-S GPS will automatically calculate and predict single ephemerides (Max. up to 3 days) when powered on, and save this predicted information into memory. The Eco Pro-S GPS will use this information for positioning if there is insufficient information from satellites, making this function helpful for positioning in weak signal environments.

Before the EASY™ function works properly, the Eco Pro-S GPS needs to collect enough information from satellites. The GPS usually needs 1-2 minutes to collect all information from satellites after the first fix. Please allow the GPS to remain on for 1-2 minutes after the first fix for the initial use.

The Eco Pro-S GPS has a memory backup capacitor inside. The capacitor can provide approximately two minutes of power to the internal memory after disconnection from the camera or battery change. To avoid the loss of ephemeris data in the internal memory, the Eco Pro-S GPS should be connected to the camera at all times. The internal memory consumes a very small amount of energy and will not affect the camera's battery life. As ephemeris data is only valid for a maximum of 3 days, the Eco Pro-S GPS should be disconnected from the camera if the camera will not be used for a long period of time.

NOTE

• LED on Eco Pro-S GPS only represents the status of Eco Pro-S GPS, but not the reception of GPS data to the DSLR camera.
• GPS data are only recorded when the GPS icon is displayed on the top LCD panel of the DSLR camera. Please make sure that the GPS icon is displayed before shooting.

GPS Status LED Indicator for Eco Pro-S GPS Fix (II)

When Eco Pro-S GPS connects to Nikon Coolpix P7700:

NOTE

• LED on Eco Pro-S GPS only represents the status of Eco Pro-S GPS, but not the reception of GPS data to the camera.
• GPS data are only recorded when a specific GPS icon (described in the original PDF) is displayed on the shooting screen of the camera. Please ensure the correct icon is displayed before shooting.

Last Position Retention (“LPR”)

The Eco Pro-S GPS is able to provide the last known GPS position with current UTC date / time (1) to the DSLR camera even if the GPS signal is lost or the unit is out of GPS coverage.

• No fix will be reported when there is no GPS position. The camera's GPS icon will flash, and no GPS data will be recorded.
• A first fix is needed during initialization before the LPR works properly.
• The current GPS position will be immediately reported to the camera once a new fix is available.
• The last known GPS position with current UTC date / time will be continuously reported when the GPS signal is lost or the unit is out of GPS coverage, until a good position fix is obtained.
• The LPR function works only in “ON” power mode. The last known position will be cleared once the power turns off.
