DataTrans Plus FEATURES and DISPLAYS 1
® INTRODUCTION Welcome to Oceanic and thank you for choosing DataTrans Plus! Your new DataTrans Plus is a two component, hoseless, integrated system that consists of a computer Display Module and a radio frequency Transmitter that will be installed into a high pressure port of your regulator first stage, or is built into an Oceanic DX3™ Integrated first stage regulator. The transmitter sends tank pressure data to the display module via a low frequency signal.
DataTrans Plus and bar graphs of the Graphic Diver Interface, you’ll soon agree that the DataTrans Plus is easy to understand and use. The DataTrans Plus has a wide array of features described in detail throughout the pages that follow. Due to the importance that they be understood thoroughly prior to using the DataTrans Plus, information will be expanded upon and some refreshed as you proceed. Relax and read through the complete guide.
® INTERACTIVE CONTROL CONSOLE The DataTrans Plus is a unique dive computer with interactive controls that allow you to select various display options and access specific information when you choose to see it. The Interactive Control Console consists of the Advance (Left) button and Select (Right) button (Fig. 1). ® Advance Select The control buttons can be pressed repeatedly, releasing upon hearing a beep, or held in to scroll and continue as you set or access different display modes.
DataTrans Plus Also while on the surface, you can access the following modes with the Control Console: • FO2 mode - to program the percentage of oxygen in the nitrox mix. • Plan mode - to view no decompression limits and plan your next dive. • Log mode - to view data from your 12 most recent dives. • History mode - to view the total number of dives, maximum depth, etc. • Set mode - to establish prefered selections.
® NO DECO C.Z. O2 C.Z. DECO dible alarm sounds to alert you to check this information. These concise, simple messages (Fig. 3), such as “TOO FAST” or “TOO DEEP" are displayed in the language that you choose during setup. Each DataTrans Plus numeric and graphic display represents a unique piece of information. It is imperative that you understand the formats, ranges, and values of the information represented to avoid any possible misunderstanding that could result in error.
DataTrans Plus bar graphs are located next to green, yellow, and red color coded portions of the peripheral decal that denote normal, caution, and danger zones, respectively. When underwater, you can quickly focus on the bar graphs to make sure that they are in the green. You can quickly verify that you're not getting too close to the no decompression limit or the oxygen tolerance limit, or ascending too fast, or consuming breathing gas too fast, or running low on breathing gas.

The DataTrans Plus calculates Breathing Gas Time Remaining using a patented algorithm that is based on a diver's individual breathing gas consumption rate and depth. Tank pressure is measured once each second, and an average rate of consumption is calculated over a 90 second period.
® No Decompression Dive Time Remaining No Decompression Dive Time Remaining is the maximum amount of time that you can stay at your present depth before entering a decompression situation. It is calculated based on the amount of nitrogen absorbed by twelve hypothetical tissue compartments. The rates each of these compartments absorb and release nitrogen is mathematically modeled and compared against a maximum allowable nitrogen level.
DataTrans Plus the findings in the Recreational Dive Planner™ distributed by PADI. Oxygen Accumulation Time Remaining Oxygen accumulation (exposure) during a dive, or 24 hour period, appears graphically as the O2 Bar Graph. As time remaining before reaching the oxygen exposure limit decreases, segments are added to the O2 bar graph.
® The value of pressure will be displayed during all dive modes when the Display Module is linked to the Transmitter and within the operating range. Linking is explained in more detail in the Pre Dive and Dive Mode section. Depth Displays During a dive, the Current Depth display, located in the upper/right portion of the screen (Fig. 16a), indicates depths from 0 to 330 feet (99.5 meters) in 1 foot (.5 meter) increments. a NO DECO C.Z.

The Message Box will read SELF - TEST and the Oceanglo backlight will illuminate the display throughout the diagnostic check.
DataTrans Plus During the diagnostic mode, battery voltage level of both the Display Module and the Transmitter are measured to determine if sufficient voltage is available to maintain operation for one day of diving. If there is not enough battery voltage in the Display Module, it will deactivate itself or would not have activated at all. If there is not sufficient voltage in the Transmitter, the Link icon and a tank pressure of "00" PSI will flash on display (Fig. 29).
® Low Battery conditions and battery power conservation are described in more detail in the Care & Maintenance section. WARNING: If either or both of the Low Battery icons remain on display following diagnostics, Oceanic strongly recommends that you DO NOT dive until the batteries are replaced. See the battery replacement procedure on page 99. DI RESP O VER If no dive is made within 2 hours after initial activation, the Display Module will automatically deactivate to conserve its battery power.
DataTrans Plus SURFACE MODE Surface Mode immediately follows Diagnostic Mode after initial activation (Fig. 30), or after the linking procedure has been performed. It also appears after a dive when you ascend shallower than 3 feet (1 meter). Surface Mode is identified by the Surface Time icon. Information displayed includes Tank Pressure, Depth (00 FT), Surface Time with flashing colon, Temperature, and Time of Day with colon flashing.
® Menu - The main menu allows interactive access from the Surface Mode to various other modes used while on the surface.

A coiled antenna inside the Display Module receives the signal when it is positioned within a zone parallel to or at a 45 degree angle to the Transmitter as shown on page 46.
® after the Display Module is moved back into its correct position. An interruption may also occur while the Display Module is in an area 3 to 4 feet (1 meter) of a running dive propulsion vehicle. The link will be restored within 4 seconds after the vehicle motor is shut off or when the Display Module is moved out of this area. When using a photo strobe, temporary link interruption may occur shortly after the strobe flashes. The link will be restored in 4 seconds.
DataTrans Plus FO2 MODE WARNING: The percentage of oxygen (FO2) in the nitrox mix being used must be set 'before each' nitrox dive. The DataTrans Plus can be used either as an Air computer or a Nitrox computer. After activation, the Display Module will operate as an Air computer without displaying information associated with oxygen calculations, unless it is set for a percentage of oxygen (FO2) other than Air (numerical value between 21 and 50 %). 5 0 10 20 30 40 60 50 ® Fig.

DECO FT PSI 0 5 10 20 30 40 50 60 When set with an FO2 value of 'Air', the DataTrans Plus will perform calculations the same as if FO2 were set for 21% oxygen, internally accounting for oxygen loading for any subsequent Nitrox dives. However, oxygen related displays, warnings, and the O2 bar graph will not appear on the LCD display for that dive (Fig. 55), or subsequent dives, unless FO2 is set for a numerical value (21 to 50 %). Setting FO2 for a Nitrox Dive ® Fig.
DataTrans Plus WARNING: The DataTrans Plus will default to an FO2 value of 50 after a 10 minute surface interval following a nitrox dive. Therfore, this procedure must be performed prior to descent on each and every nitrox dive, even if the percentage of oxygen in the nitrox mixtures used remains the same. To set (enter) a numerical value for the percentage of oxygen (FO2) in your nitrox mix, perform the following procedure beginning in the Surface Mode: 1.
® PLAN MODE Oceanic strongly recommends that you access the Plan Mode prior to every dive to review the Pre Dive Planning Sequence (PDPS) that will help you plan your dive as required to avoid exceeding no decompression, or oxygen exposure limits.
DataTrans Plus If FO2 was set for a numerical value, FO2 and the value set will appear as the first screen (Fig. 59), followed by a screen showing the maximum depth that can be achieved for an oxygen partial pressure of 1.60 ATA for that FO2 (Fig. 60). The DataTrans Plus then scrolls through the Pre Dive Planning Sequence (PDPS), displaying a sequence of depths from 30 to 160 feet (9 to 48 meters) in 10 foot (3 meter) increments.
® NO DECO C.Z. DECO C.Z. O2 FT Fig. 61 - Nitrogen Controlled NO DECO C.Z. DECO C.Z. O2 FT After scrolling once through depth and dive times available, the DataTrans Plus will automatically return to the Surface Mode. Plan Mode can be accessed and the sequence repeated as often as you choose. If you wish to interrupt the Pre Dive Planning Sequence to return to the Surface Mode, you may do so at any time by pressing either control button.
DataTrans Plus WARNING: The DataTrans Plus must be manually activated and be in an operating mode prior to start of a dive. The unit will not activate automatically by immersion in water. Also, FO2 must be set prior to commencing each nitrox dive. NO DECO C.Z. O2 C.Z. DECO FT PSI NO DECOMPRESSION DIVE MODE After it has been manually activated and completed its diagnostic checks, the DataTrans Plus will enter the No Decompression Dive Mode when you descend deeper than 5 feet (1.5 meters).
® As your depth and elapsed dive time increase, the Tissue Loading Bar Graph will fill with segments (green to red) to represent the absorption of nitrogen; and if FO2 was set for a value other than 'Air', the O2 bar graph will fill with segments (green to red) to represent oxygen accumulation for that dive, or 24 hour period, whichever is greater. The Gas Time Remaining bar graph will recede from green to red as breathing gas time remaining decreases from 60 to 0 minutes.
DataTrans Plus VIOLATION MODES The DataTrans Plus enters Violation Modes when it is unable to predict an ascent procedure. GAUGE MODE If the DataTrans Plus enters a Permanent Violation Mode, it will not display information relating to nitrogen or oxygen loading for the remainder of that dive or for subsequent dives conducted during the 24 hour period after surfacing. NOTE: Decompression Dive Mode, Violation Modes, and Gauge Mode are each described in the Handling the Extremes section. NO DECO C.Z.
® If you have not entered Decompression Mode, a safety stop made between 15-20 feet (5-6.5 meters) is strongly recommended as a standard procedure before completing your ascent. You should make every effort to complete all of your ascents with the Tissue Loading Bar Graph inside of the green zone.
DataTrans Plus ALTITUDE DIVING The mathematical model within the DataTrans Plus accounts for the reduced No Decompression dive time available at higher elevations based on NOAA (National Oceanic and Atmospheric Administration) guidelines. When diving in high altitude lakes or rivers from 2,000 to 14,000 feet (610 to 4,268 meters), the DataTrans Plus will adjust automatically, providing corrected depth and reduced No Decompression and Oxygen Exposure times.

DataTrans Plus HANDLING THE EXTREMES 71
® EMERGENCY DECOMPRESSION There are few legitimate excuses for making unplanned Decompression dives, and the consequences of this type of diving can be severe. Decompression diving requires special training and support. The DataTrans Plus is intended for use by recreational divers not engaged in intentional decompression diving. Decompression features are provided only for emergency situations.
DataTrans Plus The DataTrans Plus is a sophisticated instrument designed with capabilities that go beyond the range of recreational diving with compressed air. It should not be considered, however, that these built-in capabilities provide any implied approval or consent from Oceanic for individuals to exceed the defined limits of recreational dive profiles, as agreed on by all internationally recognized training agencies. Decompression diving should therefore be strictly avoided.
® WARNING: Existing data for making planned decompression dives is extremely limited, and virtually nonexistent for repetitive decompression diving. You must therefore avoid decompression diving and allow a surface interval of at least 24 hours before reentering the water in the event a dive requiring emergency decompression is made. If you're not careful, it is possible to enter decompression rapidly, whether at deep depths or during repetitive dives. R2 NO DECO C.Z. O2 C.Z.
DataTrans Plus GAS TIME REMAINING DURING DECOMPRESSION NO DECO C.Z. Once you enter Decompression Mode, you will need to refer to the Gas Time Remaining bar graph for Breathing Gas Dive Time Remaining information. When Breathing Gas Time Remaining decreases to 5 minutes, the tank pressure numerals will flash and a Double Beep will sound (Fig. 87).
® CAUTION ZONE (C.Z.) Your dive training taught you not to get too close to the No Decompression limits. The yellow Caution Zone (C.Z.) of the Tissue Loading Bar Graph (Fig. 89) offers you a convenient way to consistently monitor how close you are coming to the No Decompression limit. Oceanic suggests always leaving the water with the Tissue Loading Bar Graph in the green No Decompression (NO DECO) zone. WARNING: Never exit the water with the Tissue Loading Bar Graph in the red decompression (DECO) zone.
DataTrans Plus DECOMPRESSION DIVE MODE NO DECO C.Z. O2 C.Z. DECO The DataTrans Plus will help you to avoid and manage decompression. FT PSI WARNING: Oceanic recommends the application of responsible diving practices and does not recommend decompression diving, or diving deeper than 130 feet (39 meters), as these practices will greatly increase your risk of decompression sickness. Decompression Dive Mode (Fig.
® never ascend shallower than your decompression ceiling. Doing so will greatly increase your risk of decompression sickness, and place the DataTrans Plus into a Conditional Violation Mode described later. When coping with surge and swells, it may be difficult to stay at an exact depth. You should stay slightly deeper (Fig. 92) than the required stop depth indicated until the next shallower stop depth appears. Then, you can ascend to, but not shallower than, that indicated ceiling stop depth. NO DECO C.
DataTrans Plus VIOLATION MODES The Violation Modes that the DataTrans Plus can enter, depending on the situation, are termed Conditional, Delayed, and Immediate. Gauge Mode and Permanent Violation Mode are continuations of these Violation Modes. It is important to understand each different Violation Mode and how to carry out emergency procedures in the event you enter one.
® If you descend below the required decompression ceiling before 5 minutes have elapsed, the DataTrans Plus will continue to function as if no violation had occurred. In this case, no off-gassing credit will be given, and for each minute above the ceiling 11/2 minutes of penalty time is added to decompression stop time. The added penalty decompression time will have to be 'worked off' first, before obtaining off-gassing credit.
DataTrans Plus The audible alarm will beep once per second and the Message Box will alternately flash CEILING and VIOLATION until you descend below the required ceiling stop depth. As previously described, you would then need to follow the ceiling stop depths and times toward the surface as the Tissue Loading Bar Graph recedes into the caution (C.Z.) zone. 2. Your necessary decompression requires a ceiling stop depth between 60 feet (18 meters) and 70 feet (21 meters).
® After Total Ascent Time reaches zero and the Tissue Loading Bar Graph recedes into the yellow caution (C.Z.) zone, you can surface. However, to add a greater margin of protection, Oceanic strongly recommends that you wait until the segments of the Tissue Loading Bar Graph are well within the 'green' no decompression (NO DECO) zone, unless a low tank pressure condition requires you to surface. 3. You descend deeper than 330 feet (99.5 meters). R2 NO DECO C.Z. O2 C.Z.
DataTrans Plus IMMEDIATE VIOLATION MODE Warning: The DataTrans Plus enters Immediate Violation Mode when a situation totally exceeds its capacity to predict an ascent procedure. These dives represent gross excursions into decompression that are beyond the boundaries and spirit of the DataTrans Plus design. If you are following these dive profiles, Oceanic advises you not use a DataTrans Plus dive computer.

The Tissue Loading Bar Graph and O21 Bar Graph flash, while the Message Box flashes VIOLATION.
DataTrans Plus EXCEEDING MAXIMUM OPERATING DEPTH Although the DataTrans Plus will withstand the pressures found at 330 feet (99.5 meters), the depth that you can still use all of its features could be much shallower. WARNING: The maximum recommended sport diving depth limit is 130 feet (39 meters). Any deeper dive should be avoided. Special training, equipment, and support are necessary for this type of diving.
® OXYGEN EXPOSURE There are few legitimate excuses for exceeding the maximum limits for exposure to oxygen, and the consequences of CNS (Central Nervous System) oxygen toxicity can be severe, resulting in Gran Mal convulsions and drowning. Diving with enriched nitrogen-oxygen (nitrox) mixtures requires special training and certification.
DataTrans Plus PARTIAL PRESSURE OF OXYGEN NO DECO C.Z. O2 C.Z. DECO As depth increases during the dive, the partial pressure of oxygen increases. As you approach the depth limit for the FO2 value set before that dive, the DataTrans Plus will alert you and display the PO2 level while you reduce oxygen partial pressure according to your training.
® depth at a safe rate in accordance with your nitrox training. If you continue the dive at your current depth, or descend deeper, your exposure to CNS oxygen toxicity will increase. OXYGEN ACCUMULATION It is also important that you understand that conducting repetitive dives using enriched nitrogen-oxygen (nitrox) mixtures can lead to oxygen buildup, reducing oxygen tolerance while increasing the risk of pulmonary oxygen toxicity. The O2 bar graph (Fig.
DataTrans Plus HIGH OXYGEN ACCUMULATION NO DECO C.Z. R2 O2 C.Z. DECO Your nitrox dive training taught you not to get too close to the oxygen tolerance limits. The O2 Bar Graph provides you with a convenient graphic representation of your oxygen accumulation, displaying either oxygen accumulated during that dive or during your repetitive dives conducted during that 24 hour period, whichever of the two is greater at that time.
® Body metabolism varies from person to person, and even from day to day. If you are feeling less than 100%, or you are in less than perfect physical shape, use the caution (C.Z.) zone as a visual reference to place a wider margin of protection between you and the limits of oxygen tolerance.

DataTrans Plus limits, and a critical reason to avoid entering decompression. Regardless of your diving habits, Oceanic advises you to dive with additional backup instrumentation that can provide the data necessary to properly surface if and when your primary instruments fail. As with any other piece of equipment, unforeseen things can happen. By preparing ahead of time, you can spare yourself a great deal of frustration and disappointment.

DataTrans Plus REFERENCE 105
® MORE ABOUT FLYING AFTER DIVING In 1990 the Undersea and Hyperbaric Medical Society (UHMS) published a set of guidelines aimed at minimizing the possibility of decompression sickness due to flying too soon after diving. The UHMS suggests* divers using standard air cylinders and exhibiting no symptoms of decompression sickness wait 24 hours after their last dive to fly in aircraft with cabin pressures up to 8,000 feet (2,440 meters).
DataTrans Plus Both the UHMS and DAN agree that “There can never be a flying after diving rule that is guaranteed to prevent decompression sickness completely. Rather, there can be a guideline that represents the best estimate for a conservative . . . surface interval for the vast majority of divers. There will always be an occasional diver whose physiological makeup or special diving circumstances will result in the bends”.
® Atmospheric pressure decreases as altitude increases above sea level. Weather systems and ambient temperature also affect barometric pressures. Consequently, depth reading instruments that do not compensate for the decrease in pressure indicate depth readings shallower than the depth they are actually at. The DataTrans Plus automatically compensates for decreased ambient pressure when activated at high altitudes up to 14,000 feet (4,267 meters).
DataTrans Plus MORE ABOUT NITROX DIVING WARNING: Diving with enriched nitrogen-oxygen (nitrox) mixtures requires special knowledge of the variations imposed upon divers, their activities, and their equipment by the increased percentage of oxygen. Oceanic recommends completion of a specialized Nitrox training course by a recognized training agency prior to diving with any enriched nitrogenoxygen (nitrox) mixtures.
® tified by a recognized training agency to teach diving with nitrox. The DataTrans Plus is not intended for use by military or commercial divers. WARNING: In the event that you exceed the maximum limit of per dive allowable oxygen exposure, it is recommended that you allow a surface interval of at least 2 hours before reentering the water. If you exceed the maximum limit of 24 hour period allowable oxygen exposure, you should allow a surface interval of at least 24 hours before reentering the water.

DataTrans Plus RESPONSIBLE COMPUTER DIVING Since the advent of dive computers, it is a common mistake to assume that the old traditional rules of diving no longer apply, but the truth is just the opposite. Before you dive using your DataTrans Plus, keep these basic rules in mind: • Plan each dive, and dive your plan - Your computer was not designed to make decisions for you, only to provide you with the information you need to make responsible decisions for yourself.
