PC INTERFACE

The i550 is configured with a Data Port located on the side of the module that enables it to be connected to a PC
through a USB port using a special interface cable. The cable is either included or available as an optional acces-
sory depending on the computer package purchased. The USB Driver required for the interface system is down-
loadable from www.aqualung.com.
The Settings Upload portion of the program can be used to set/change the Set AL group (Alarms), Set UTIL group
(Utilities), and Set TIME group (Time/Date) using the same Interface System. The FO
entered using the i550 button controls.
Information available for retrieval (download) from the i550 to the PC Download portion of the program includes
items such as dive number, surface interval time, depth, dive time, start dates/time, lowest temperature, sampling
rate, set points, N2 Bar Graph, and ASC Bar Graph.
The i550 checks for the presence of an interface device connection to the Data Port once every second* while in
Surface Mode.
*Checks are not made if the H2O ACT (water activation) contacts are wet.
Upon sensing an interface connection, the requesting device (PC) connects to the i550. It is then prepared for
uploading settings or downloading data, which is initiated using the PC program. During the process there is a PC
countdown (2 minutes) screen displayed on the i550.
Prior to attempting to download data from your i550 or upload settings to it, review the HELP section of the inter-
face program. It is recommended to print those sections of HELP that you consider appropriate for your interface
activities.

CARE AND CLEANING

Protect your i550 from shock, excessive temperatures, exposure to chemicals, and tampering. Protect the lens
against scratches with an Instrument Lens Protector. Small scratches will naturally disappear underwater.
• Soak and rinse the i550 in fresh water at the end of each day of diving, and check to ensure that the areas
around the Low Pressure (Depth) Sensor, PC Interface Data Port, and buttons are free of debris or obstructions.
• To dissolve salt crystals, use lukewarm water or a slightly acidic bath (50% white vinegar/50% fresh water). After
removal from the bath, place the i550 under gently running fresh water. Towel dry before storing.
• Keep your i550 cool, dry, and protected during transport.

rect No Decompression Dive Times in the planner, or showing a depth reading at the surface) or displays
