Used in combination with a DiverDataCable (DDC)*, this downloading unit stores data in a non-volatile memory drive, meaning that even if the battery is empty the data will still be available. A full battery can support more than 10 days of operational use and a LED will indicate when the battery voltage is low.

• Diver data download indicators.
• Supplied with 1 GB memory card.
• Powerful rechargable battery.
• Recharge the battery while connected to the USB port.
• Low battery indicator.
• Integrated data synchronisation option in Diver-Office.

• Simple to use.
• Eliminate errors on accidentally reprogramming or stopping Divers.
• Store more than 5,000 Diver (full memory) downloads on the supplied memory card.
• Read the memory of a few hundred Divers with a fully charged battery.
• A fully charged battery can support more than 10 days of operational use.

1. General

The Diver-Mate is an instrument which can be used to retrieve data from a Diver in the field.

The Diver-Mate supports the following Diver data loggers:

• ( DI7xx ) Cera-Diver (measures temperature and groundwater level)
• ( DI6xx ) Micro-Diver (measures temperature and groundwater level)
• ( DI5xx ) Mini-Diver (measures temperature and groundwater level)
• ( DI24x ) MTD-Diver (measures temperature and groundwater level)
• ( DI250, DI500 ) Baro-Diver (measures barometric pressure and temperature)
• ( DI26x ) CTD-Diver (measures conductivity, temperature and groundwater level)

The Diver must be connected to a DiverDataCable (DDC). Upon connection with a DDC the Diver-Mate will automatically download the data from the connected Diver.

This data is stored on a miniSD card inside the Diver-Mate. The miniSD card can be
removed from the Diver-Mate and inserted into a card reader. Alternatively, data can also be read by connecting the Diver-Mate with the supplied USB cable (type USB A to mini-USB B 5 pin), to a PC. Upon connection with a USB cable the battery of the Diver-Mate will be charged.

The Diver-Mate meets the following general specifications:

2. Knowing the Diver-Mate

The Diver-Mate, see the figure below, consists of 3 parts:

• The main body
• The cap
• The memory card

Two sets of 4 LEDs (lights), one set on each side of the main body, indicate the status and operation of the Diver-Mate. The functions of these LEDs are indicated in the figure below.

The cap can be removed from the main body. This will allow the connection of the USB cable and removal of the SD card. Under the cap are two more LEDs. The functions of these LEDs are indicated in the figure below.

3. Using the Diver-Mate

Charging the Diver-Mate

• Connect the Diver-Mate to a PC using the supplied USB-cable.
• It takes approximately 9 hours to charge a completely empty battery

Downloading data from a Diver to a Diver-Mate

• Keep the cap on the Diver-Mate to assure that it is waterproof.
• Connect the Diver-Mate to the DDC. The Diver-Mate will recognize it is connected to a DDC and will start reading the data (yellow DATA LED blinking). If no Diver is connected to the DDC the error LED will light up after ± 10 seconds. Disconnecting the Diver-Mate from the DDC cable will stop the yellow LED from blinking and will also stop the data download from the Diver.

The green LED (OK) is turned on when the download is successfully completed.
The red LED (ERROR) will be turned on:

• If an error occurred during data download or
• If the Diver-Mate is disconnected during reading or
• If no Diver is connected to the DDC or
• If the miniSD card is not inserted in the Diver-Mate.

All LEDs are turned off when the Diver-Mate is disconnected from the DDC. The Diver-Mate will go into sleep-mode to preserve power.

Downloading data from the Diver-Mate to a PC

• Remove the cap
• Insert the miniSD card into a PC or alternatively connect the Diver-Mate with a PC using the USB cable. The connected miniSD card or the Diver-Mate will act as a USB-memory stick. If the Diver-Mate is connected to a PC the yellow LED (BUS) will be turned on. This indicates that the PC has recognized the unit as a portable disk.
• Use Diver-Office to manage the data on the Diver-Mate. The data can easily be copied to your PC, deleted from the Diver-Mate if desired and exported to MON or CSV files if indicated.

For more details please see the manual and the help function of Diver-Office. Alternatively Windows Explorer can be used to copy the stored DAT files anywhere on your PC.

4. Data storage

The Diver data is stored on a miniSD card which is provided with the Diver-Mate (a 512 MB, however other miniSD cards can be also used, up to maximum 2 GB). The data is stored in the format serial number-xx.DAT using the serial-number of the Diver (serial-number = 5 characters) and a sequence number (xx = 01 to 99) as file name. The extension is DAT (example: 12767-01.DAT). In case there is already data from one particular Diver on the card, the newly generated file will have a higher sequence number. The newly generated sequence number will always be higher than the highest found corresponding serial number.

If a DAT file with a sequence number of 99 is stored on the Diver-Mate it will no longer be possible to download data from that particular sequence number/Diver. The file must first be removed.

If data was not properly downloaded it will be stored in the format serial-number-xx.ERR
(Example 32196-01.ERR).

The supplied miniSD card can store more than 1,000 Diver (full memory) downloads. Once the data has been downloaded it can be accessed as a regular USB memory stick. This can be done automatically on download using Diver-Office (see manual and help  function in Diver-Office).

5. Battery

With a fully charged battery approximately 500 Divers with full memory can be read. The battery is charged when connected to the PC with the USB cable. The red LED (CHARGE) next to the mini USB connector indicates charging. When the red LED turns off the battery is fully charged.
