1. INTRODUCTION

Congratulations on your choice of the SUUNTO Spyder Advanced Computer Watch. The Spyder is a compact and most sophisticated dive instrument that will give you years of trouble-free and joyful diving. The Spyder Advanced Computer Watch will provide you with important information that you will need during, between, and after your dives.
1.1 IMPORTANT INFORMATION
NEVER test the Spyder in a pressure chamber. Only authorized SUUNTO service personnel may test the Spyder and make test dives in a pressure chamber, as it requires special equipment and training. Battery Battery life of the Spyder is about 1.5 years when used as a watch. Diving, alarms and use of the backlight shorten the battery life. Note, that the battery loaded at the factory may discharge during the shipment and storage. Temperature affects the battery voltage. If the Spyder is stored at low temperatures (particularly below freezing point), the low battery warning may be displayed even though the battery has enough capacity in warmer conditions. The battery should be replaced only by an authorized SUUNTO dealer or distributor. Water Resistance This device will withstand the ingress of water at the static pressure of 20 ATM (200 m [660 ft]). Note, however, that dynamic pressure generated by movement underwater is greater than static pressure.
Depth Sensor The built-in depth sensor of the Spyder is a sophisticated precision instrument. The depth sensor cover may be opened only by an authorized SUUNTO dealer or distributor. NEVER try to open the cover yourself. Keep the area around the depth sensor clear from dirt, sand, dust or other substances. Rinse the device thoroughly with fresh water and dry it with a soft towel. Never use pins, needles or other objects to clean the depth sensor. Water Contact The water contact controls the automatic activation of the Dive Mode, as well as the automatic return from the Dive Mode to the Time Mode. Contamination or dirt on the water contact may prevent these automatic operations. It is, therefore, important that the water contact is kept clean. The contact can be cleaned with fresh water and a soft pencil eraser. NOTE: Water or moisture build-up around the water contact may cause the contact to activate automatically. This can happen, e.g., when washing your hands or sweating. If the water contact activates in the Time Mode, an ACW text will appear on display (see Fig. 4.2. b), and it will be shown until the water contact deactivates, or the Spyder enters the Dive Mode automatically. To save the battery power, you should deactivate the water contact by cleaning it and/or drying it with a soft towel. Exposing the Spyder to great temperature changes may cause the Dive Mode to activate automatically. The Spyder will return to the normal display (timekeeping) 10 minutes after the water contact has dried. To save the battery power and also to enable the use of the timekeeping display, it is recommended to return to the normal display by using the push buttons.

1.4 GETTING STARTED

Before you start using the Spyder you must read and understand this manual in its entirety. Before your first actual dive it is of utmost importance that you read Section 2,
For Your safety, and Section 4, Diving with the Spyder. Section 3, Time Mode, teaches you how to use the clock functions of the Spyder. Section 5, Setting Mode, gives instructions on how to set the time, date, daily alarm and the time format in the clock, and the depth alarm and Altitude and Personal Adjustments in the dive computer. Section 6, Memories and Data Transfer teaches how to access the memory functions and how to transfer the data from the Spyder to a PC. Section 7, Care and Maintenance, gives you detailed information about the care and maintenance of your Spyder, and the battery replacement. Finally, there is technical information in Section 8, and information on service and warranty in Section 9.
1.5 METRIC AND IMPERIAL UNITS
All examples in this manual are shown in metric units, including meters and C. The corresponding imperial units are shown in brackets. The Spyder is also available in imperial units, i.e. feet and F. THE UNITS CANNOT BE CHANGED BY THE USER.
VERIFY THAT THE UNITS OF MEASURE, WHETHER METRIC OR IMPERIAL, ARE CORRECT BEFORE DIVING! Any confusion resulting from improper units may cause the diver to commit errors that may lead to serious injury or death.

2. FOR YOUR SAFETY

Do not attempt to use the Spyder without reading this instruction manual in its entirety, including all the warnings in the beginning of this manual and the entire section 2, For Your Safety. Make sure that you fully understand the use, displays and limitations of the Spyder. If you have any questions about the manual or the Spyder, contact your SUUNTO dealer before diving with the Spyder. Always remember that THE DIVER IS RESPONSIBLE FOR HIS OR HER OWN SAFETY! When used properly the Spyder is an outstanding tool for assisting properly trained, certified divers in planning and executing standard and multi-level sport dives within the described no-decompression limits. It is NOT A SUBSTITUTE FOR CERTIFIED SCUBA INSTRUCTION including training in the principles of decompression.

2.1 SAFETY PRECAUTIONS

Sharing the Spyder
THE SPYDER SHOULD NEVER BE TRADED OR SHARED BETWEEN USERS WHILE IT IS IN OPERATION! Its information will not apply to someone who has not been wearing it throughout a dive or sequence of repetitive dives. Its dive profiles must match that of the user. If it is left on the surface during any dive, it will give inaccurate information for subsequent dives. No
dive computer can take into account dives made without the computer. Thus any diving activity 48 hours prior to initial use of the computer may give misleading information, which may substantially increase the risk of decompression sickness and must be avoided. Altitude and Personal Adjustments
SET THE CORRECT ALTITUDE AND PERSONAL ADJUSTMENT MODES! Failure to properly select the Altitude and Personal Adjustment Modes correctly will result in erroneous data and can greatly increase the risk of decompression sickness. More information about this is given in Section 4.5, High Altitude Dives and Personal Adjustment.
SET THE CORRECT ALTITUDE ADJUSTMENT MODE WHEN DIVING AT ALTITUDES GREATER THAN 700 M [2300 FT]! When diving at altitudes greater than 700 m [2300 ft] the altitude adjustment feature must be correctly selected in order for the computer to calculate no-decompression status. Failure to select the Altitude Adjustment Mode correctly will result in erroneous data and can greatly increase the risk of decompression sickness.
THE SPYDER IS NOT INTENDED FOR USE AT ALTITUDES GREATER THAN 2400 M [8000 FT]. Diving at altitudes above this limit may significantly increase the risk of decompression sickness. Decompression Dives SUUNTO does not recommend this instrument to be used to conduct decompression dives. However, if through carelessness or emergency a diver exceeds the no-decompression limits on a dive, the Spyder will provide decompression information required for ascent. After this the Spyder will continue to provide subsequent interval and repetitive dive information.
DO NOT USE THIS INSTRUMENT TO CONDUCT DIVES WITH NECESSARY DECOMPRESSION STOPS! SUUNTO does not recommend this instrument to be used to conduct these types of dives. Decompression Diving limits the divers ability to ascend directly to the surface and may substantially increase the risk of decompression sickness. Emergency Ascents In the unlikely event that the Spyder malfunctions during a dive, follow the emergency procedures provided by your certified dive training agency or, alternatively, immediately ascend at a rate slower than 10 m/min [33 ft/min] to a depth between 3 and 6 meters [10 to 20 ft] and stay there as long as your air supply will safely allow.

DO NOT USE THE SPYDER WITH NITROX MIXES! The mathematical calculation model of the Spyder applies for use with standard breathing air only (approximately 21% oxygen and 79% nitrogen by volume). Therefore, using the Spyder for diving with Nitrox or other mixed gases may lead to serious injury or death.

3. TIME MODE

The Spyder has calendar clock, stopwatch and alarm clock functions. The calendar clock and the stopwatch are operated in the Time Mode (Fig. 3.1).

Fig. 3.1 The Time Menu

The mode is indicated in the display by the TIME text and the mode indicator (Fig. 3.2). The time and date and the daily alarm are set in the Setting Mode (see section 5, Setting Mode).

3.1 TIMEKEEPING DISPLAY

The timekeeping display (Fig. 3.3) is the primary display of the Spyder. When the Time Mode is entered from other modes, the timekeeping display activates within two seconds, if no button is operated. In other modes (except in the Diving or Stopwatch Modes), if no button is operated within 10 minutes, the Spyder beeps and returns to the timekeeping display automatically. Either the date (Fig. 3.3 a) or the seconds of the current time (Fig. 3.3 b) are shown on the bottom line of the timekeeping display. Press the or button to select the desired display option. Next time when you enter the timekeeping display, the Spyder will show the selected option. The TIMER text blinks on the display if the stopwatch is running. The display is illuminated by holding down the button for more than two seconds. To set the time and date, refer to section 5.1, Setting Time and Date.

7. CARE AND MAINTENANCE

The SUUNTO Spyder Advanced Computer Watch is a sophisticated precision instrument. Remember to treat it as such. It has been designed to withstand the rigors of scuba diving.
7.1 CARE OF YOUR ADVANCED COMPUTER WATCH
NEVER try to open the case of the Spyder or remove the buttons. NEVER try to open the depth sensor cover yourself. Service your Spyder every two years or after 200 dives (whichever comes first) by an authorized dealer or distributor. This service will include a general operational check, replacement of the seals, buttons and battery, and a water resistance check. The service requires special tools and training. Therefore, it is advisable to contact an authorized SUUNTO dealer or distributor for biennial service. Do not attempt to do any service that you are not sure about how to do. Should moisture appear inside the Spyder have it checked immediately by your SUUNTO dealer or distributor. Should you detect scratches, cracks or other such flaws on the mineral crystal of the display that may impair its durability, have it replaced immediately by your SUUNTO dealer or distributor. Check the spring bars holding the strap and the buckle for flaws. If the flexibility of the spring bars has reduced, have them replaced immediately by your SUUNTO dealer or distributor Wash and rinse the unit in fresh water after every use. Protect the unit from shocks, extreme heat or direct sunlight and chemical at74
tack. The Spyder cannot withstand the impact of heavy objects like scuba cylinders, nor chemicals like gasoline, cleaning solvents, aerosol sprays, adhesive agents, paint, acetone, alcohol etc. Chemical reactions with such agents will damage seals, case and finish. Store your Spyder in a dry place when you are not using it. The Spyder will display a battery symbol as a warning when the power gets too low. When this happens, the Spyder should not be used until the battery has been replaced by an authorized SUUNTO dealer or distributor (see also section 4.2.1, Activation, Prechecks and Battery Warning). Do not fasten the strap of your Spyder too tightly. You should be able to insert your finger between the strap and your wrist. Use extension strap when fastening the Spyder on your exposure suit.

7.2 MAINTENANCE

If left without care for an extended period, a thin film (often invisible to the eye) will cover the unit. Much like the buildup on the glass of an aquarium, this film is the result of organic contaminates found in both salt and fresh water. Suntan oil, silicone spray and grease will speed up this process. As a result of this buildup, moisture will be trapped next to the water contact and will not allow your Spyder to operate properly. The water contact can be cleaned with a soft pencil eraser. IMPORTANT: The Spyder should be soaked, then thoroughly rinsed with fresh water and then dried with a soft towel after each dive. Make sure that all salt crystals and sand particles have been flushed out. Check the mineral crystal for

possible moisture or water. DO NOT use the Spyder if you detect any moisture or water inside.
do not use compressed air to blow water off the unit do not use solvents or other cleaning fluids that might cause damage do not test or use the Spyder in pressurized air.
7.3 WATER RESISTANCE INSPECTION
Water resistance of the unit must be checked after replacement of the battery, mineral crystal or buttons. The check requires special equipment and training. You must frequently check the mineral crystal for leaks. If you find moisture inside your advanced computer watch, there is a leak. A leak must be corrected without delay, as moisture will seriously damage the unit, even beyond repair. SUUNTO does not take any responsibility for damage caused by moisture in the advanced computer watch, if the instructions of this manual are not carefully followed. In case of a leak immediately bring the Spyder to an authorized SUUNTO dealer or distributor.
8. TECHNICAL DESCRIPTION 8.1 OPERATING PRINCIPLES
The SUUNTO Spyder is a multi-functional sport diving instrument, which provides information on depths, times, and decompression requirements. Its elec76
tronic microprocessor mathematically models the absorption and release of nitrogen during all phases of diving, including ascents, surface intervals and repetitive dives. No-Decompression Limits The no-decompression limits for the first dive of the series displayed by the Spyder are for most dives to a single depth slightly more conservative than those permitted by the U.S. Navy tables, see Table 8.1 and 8.2.
Table 8.1 No-decompression time limits (min) for various depths [m] for the first dive of a series. 77
Table 8.2 No-decompression time limits (min) for various depths [ft] for the first dive of a series.
Unlike the U.S. Navy tables, the Spyder interpolates between depths, giving a diver credit for time spent in shallower water, rather than calculating no-decompression limits based on the maximum depth of a dive. As a result, no-decompression dive times permitted by the Spyder are often much longer than those that would be allowed by the U.S. Navy tables.

treat the next dive as a continuation of the previous dive. It adds the dive times, and calculates no-decompression limits or decompression stops based on excess nitrogen absorbed on both dives. In this regard, it is similar to the U.S. Navy tables. Depth Limits
SUUNTO STRONGLY RECOMMENDS THAT SPORT DIVERS LIMIT THEIR MAXIMUM DEPTH TO 40 m [130 ft]! Exposure to greater depth increases the risk of decompression sickness. However, the Spyder will calculate at greater depths to provide a wide margin of flexibility if, through carelessness or emergency, you exceed this recommended depth limit for a dive.

DIY - PC - Interface for Suunto Spyder ACW
Foreword and History This instruction is intended for people with a certain amount of manual skills and some experience in completing electronic assembly kits. You don't have to understand the function of each component of the circuit and you do not have to be a computer expert. The circuit described here has proven to be reliable and safe. A correct assembled device will never harm the dive computer nor the PC it is attached to. However I do not take any responsibility for any kind of damage. If you decide to rebuild this unit, its on your own risk. The software program for reading the ACW's memory and manage the logbooks can be downloaded from the Suunto homepage www.suunto.fi free of charge. I recommend the Suunto Dive Manager V.1.2. The circuit was developed because I simply didn't want to spend over 150 US$ for a box obviously not worth more than 50. I was convinced that Suunto won't give me any hint or tip about their interface and I knew nobody who could loan me one to copy. So I analyzed the "water sensor" contact on the ACW and traced the RS232 when the software tried to communicate over the (not present) interface to the (not present) ACW. I quickly learned about the basics of the communication like baudrate, levels, impedances. So I became able to develop a first prototype. It was provisional and looked scanty but it worked. Then I refined the mechanical concept and built a nice housing around. Then I showed the piece to a friend who just bought a Spyder and therefore I had to build another one. And then another one and so on.
PC-Interface for ACW by Roli 2000

page 1/5

Schematic
Circuit description When you look at the schematic you can find no highly sophisticated components like line drivers, multiplexers or similar. For the required baudrate of 2400 bits/second the cheap and easy-available components are sufficient. Roughly the circuit consists of two level shifters and their power supply. D1.D8 and C1, C2 care for the power supply, R1.R3 provide some protection. PC data output lines momentarily on high logic levels provide positive, those on low level provide negative supply voltage. The purpose of D1 and D5 are not obviously clear, but they are necessary to protect either of the power supply capacitors from being negative charged and possibly even causing damage to the attached computer, e.g. via the input protection diodes of U1A. IC1b along with R10, R11 provides an output voltage of -3.2V, thats the logic-high level of the ACW. Logic-low level is ground, which is also the metal case of the ACW. T1 together with R6.R8 act as an inverting level shifter for the PC's TxD line. D9 protects T1's base from being reverse biased. R9 adds some impedance for the period when the ACW is transmitting data because there is no separate contact on the ACW. This is quite a simple approach for the "control" of the half-duplex communication but I didn't want to implement multiplexers and handshake controls in the interface. And it works. IC1a acts as inverting level shifter from the small ACW levels to the RS232 levels. R4 serves for some protection. Just a word about the bandgap reference IC2 which is certainly the "most expensive" component in the circuit. I took this approach for the following reason: the device gives an accurate reference for the logic level of the ACW as well as for the threshold of the level shifter, quite independent on the power supply voltage or temperature. IC2 can be replaced by 3, forward biased, series connected 1N4148 silicon diodes or a red LED when R11 is changed to 33k, but this reduces the temperature range and variations of the power supply voltage become more critical. The same applies for the replacement of the shottky diodes D1.D8 in the power supply part with 1N4148's, where the circuit becomes more dependent on the RS232 drivers of the PC.

Electronics Assembly
There are several ways to get the components soldered together - more and less reliable ones. All of these methods require a certain amount of manual skills and experience with soldering. The simplest way is to use a printed circuit board, provided that you have one. The other, more inefficient but almost everywhere available is the use of Veroboard. I often use this technique to build prototypes. If you spend some time to think about a clever placement of the components, you need only very few pieces of thin wire for connection. It's favorable to take the mechanical aspects into consideration when you design the electronics assembly. I used spring loaded contacts with rounded tips and soldered the sleeves directly on the Veroboard. The position of the PCB inside the housing is then chosen such that the ACW fits in respect to the contacts. See the picture of the open cradle.
Test Its favorable to test the circuit before putting it into operation. All you need is a dual output adjustable power supply (two 9V batteries do the job, either) and a voltmeter. 1) Set DTR to +9V and RTS to 9V (all voltages in respect to GND). You should now be able to measure the potentials 1.25V, -3.2V indicated on the schematic. 2) Now connect TxD to 9V, too. The voltage at the computer I/O contact should become around 50mV and the voltage at RxD should be around 8.5V. 3) Finally change TxD to +9V. The computer I/O contact should become around 3V and the voltage at RxD should be near +8V. Are these tests successful, you can plug the interface to the PC and see if the Dive Manager software recognizes it by the test routine. Now you can perform your first data transfer.

The Housing

Some electronics people will have their trouble with the construction of the mechanical parts of the interface. I have found a very nice and handy housing at the German distributor "Conrad" that requires only little machining. See how I machined the housing for inserting the ACW on the pictures. One disadvantage is that the cradle is too light. It can be compensated for when you add some heavy pillars on the bottom. This lifts it up from the table which is good when you have the ACW with rubber wrist straps. To keep the ACW secure in place while communicating I added a piece of rubber normally used to protect sharp edges. That's it! Inspire yourself with the pictures and improve the design even more.

In Case of Problems First of all there are no known problems with the PC-interface or the Suunto software. In most of the cases the problem with the data transfer is due to dirt on the water sensor contact, improper COMport selection or the "COM time delay" value is not suitable for the hardware used. Here are some hints & tips: When you often get the Transfer Timed Out error message, try the following: 1. Make sure that you have your PC-interface properly connected to your PC following the instructions of the program and the Help utility. Run the TEST program from the Transfer Menu PC Interface Setup window which should recognize the COM-port to which the PC-interface is connected to. Now make sure that this COM-port is the one you have selected. 2. You can set the "COM time delay" in the Interface Setup window of the Dive Log program. The value depends on the hardware used (is it a powerful PC or not, and some other PC settings). It is advisable to experiment with different values and see which one works the best. A value of 10 should be appropriate for 95% of all computers. 3. The spring contact in the middle (out of 3) of the cradle is the most important one. Sometimes this pin does not make a proper contact to the water-sensor of your ACW. Carefully clean the three PC-interface pins and the water-sensor of your ACW with a soft eraser or dry cloth. 4. Insert the ACW into the cradle and carefully twist your ACW just a little bit to ensure a proper contact of the middle pin. Now look at your ACW's display and notice a short 'blink'. This blink tells you that the connection is made correctly and that your ACW is ready to transmit. According to the program's Help, you should set your ACW in TR-PC mode before inserting the unit into the PC-interface. However some users have good experiences when setting the ACW in PC-TR mode after the unit is inserted. 5. If you had an unsuccessful transmission just scroll through MEM - LOG - HIS to TR-PC with the upper left button of the ACW (without removing the ACW from the cradle) to try again. It is also advisable to set the ACW to MEM-mode (upper right button) before inserting into the cradle and after inserting scroll to TR-PC. Now notice the 'blink'. 6. Do not move or touch your ACW and PC-Interface while transmitting because any movements may interrupt the transfer and you have to start all over again. 7. To confirm the proper working of your ACW's TR-PC mode you can also simulate the 'blinking' effect (see 4) by using an open-bent paper-clip. Connect the paper-clip's ends between the watersensor and the metal chassis of your ACW. Now notice the 'blink'.
