1. Service Mode Programming This programming mode usually requires the locomotive to be placed on a special programming track or connected to a dedicated programmer Tsunami is an advanced line of decoders and support four types of service mode instructions Address Mode Can change CV 1 Primary Address only Register Mode Can change CVs 1 2 3 4 7 8 and 29 only Paged Mode Uses a page register to indirectly modify any CV Direct Mode Can directly change any CV Operations Mode Programming Sometimes called Ops Mode or Programming on the Main this programming mode allows the CVs to be changed while the locomotive is operating on the layout even when other locomotives are present The neat thing about this mode is that the CVs can be changed in the middle of operation allowing the engineer for example to increase the momentum rate of a locomotive after it couples to a train The main disadvantage of operations mode programming is that the CV data cannot be read back to verify its value Reading CVs Certain command stations also allow you to read a CV during Service Mode Programming which is useful to verify its current setting If you have trouble reading or verifying CVs the problem may be due to the design of your command station and not the DSD itself Tsunami and all other decoders communicate back to the command station using what s called an acknowledgment pulse which is defined in NMRA RP 9 2 3 as an incre

Tsunami has a unique feature called a Playable Whistle which allows you to set the whistle for a pressure or position response to an analog control This could be a pressure sensitive key thumbwheel or some other analog control depending on your command station In some cases each cab must be individually set up to use this feature you will need to see the documentation that came with your command station for this information as well as the value to program into CV 47 The default value for CV 47 is 0 which disables the playable whistle function Hint the effect of the playable whistle is greatly enhanced if you enable the Whistle Reverb by setting CV 161 to 1 Note Once you ve programmed the decoder to respond to the playable whistle function if you switch to different cab not programmed in this manner you will find that F2 and F3 will no longer respond Bell Control By default Tsunami uses Function F3 to turn the bell on and off There are two CVs to adjust the bell CV 114 Bell Ring Rate CV 130 Bell Volume Tsunami Steam Sound User s Guide Page 43 Bell Ring Rate The bell ring rate may be adjusted over 16 steps to simulate the sound of an air rung bell or a hand rung bell by setting CV 114 between 0 and 15 A setting of 0 yields the fastest ring rate like an air ringer while higher values produce increasingly slower ring rates The default setting for CV 114 is four but as each Tsunami decoder features a different be

11. For specific programming procedures please consult your DCC system manual Locking and Unlocking CVs The CV Lock Unlock is a relatively new feature available in some DCC decoders which allows you to program a decoder without the danger of overwriting the programming in another This especially useful in installations where multiple decoders are used For example if you have installed a function decoder in addition to the sound decoder you may wish to lock the CVs after programming to prevent accidentally programming one or the other To use the CV Lock feature implemented in CV 15 and 16 Bit 0 of CV 30 must first be set to 1 the default value is 0 This is to avoid inadvertently locking the decoder when the CV Lock feature is not needed CV 15 and 16 are used for locking and unlocking the decoder CV 15 is the Unlock Code and may be programmed to any value between 0 and 255 regardless of whether the decoder is locked or unlocked CV 16 is the Lock Code and may be set to any value between 0 and 7 but only when the decoder is unlocked Attempts to program CV 16 with a value greater than 7 will be ignored The decoder is unlocked when the value in CV 15 matches the value in CV 16 Otherwise the decoder is locked and can not be programmed in either operations mode or service mode Further a locked decoder can not be reset to its factory defaults until it is first unlocked Tsunami decoders are shipped from the factory with all CVs unlocked

Reference to determine the correct value for CV 29 Set the User Loadable Speed Curve The User Loadable Speed Table allows you to create virtually any throttle response curve you can imagine You will first need to design and program the Loadable Speed Table The Loadable Speed Table consists of 28 data points contained in CVs 67 through 94 each defining the percentage of motor voltage applied ata Table C Calculating the given speed step Each data point User Loadable Speed Table can contain a value of 0 0 255 CV Speed Full CV corresponding to 0 to 100 of Step Speed Value available motor voltage In 28 speed step mode each data point directly corresponds to a speed step In 128 speed step mode each data point corresponds to every four and a half speed steps The motor voltage for intermediate steps is interpolated by Tsunami to produce a smooth curve In 14 speed step mode alternate odd numbered data points correspond to speed steps 1 14 Important all 28 data points must be programmed even for 14 speed step mode or an unpredictable throttle response may occur while accelerating or braking O DAINIO aA HR wW P To create a speed curve begin by assuming that Tsunami will be operated in 28 speed step mode Don t worry if you are using another mode Tsunami will automatically take care of the translation between modes 1 Start by making a ta

Volume Limit CVs a value of 255 results in the maximum amount of volume change Thus the upper and lower volume limits of a given effect can be independently adjusted You could for example set CV 183 and CV 184 to zero so the rod clank volume is always constant Setting CV 181 to 250 and CV 182 to 64 results in an exhaust sound that increases volume four times under acceleration but only drops 30 during braking Try experimenting with different settings to see what the results are DDE Timbre and Cutoff Control By changing the value in CV 185 you can change the tone or timbre of the exhaust chuff A lower CV setting results in a deeper chuff Note that the exhaust cutoff automatically increases as the throttle increases This helps keep the individual exhaust chuffs crisp and distinct as the chuff rate increases You can control how much change to the basic chuff occurs by varying the setting of CV 186 A low value results in only minimal change and maintains a strong deep chuff regardless of locomotive speed At higher speeds however the chuffs may begin run into each other resulting in a strange whirring sound This can be corrected by programming a higher value into CV 186 In general the faster you are planning on operating your engine or the higher you have set CV 116 Auto Exhaust Rate the higher a setting you will need for CV 186 to maintain the proper exhaust cutoff over the locomotive s speed range Try setting CV 186 with differe
