All Aboard! Automatic Sound Effects Blunami plays a variety sound effects automatically. Automatic sound effects respond prototypically to aspects of operation, such as certain functions, speed settings, and motor load changes. Traction Motors With the pantograph extended, the whine of the tractions motors is automatically adjusted by auto-notching and Dynamic Digital Exhaust as you operate.
All Aboard! CV Programming Tutorial What is a CV? Configuration Variable (CV) is the industry-adopted term for a decoder’s user-adjustable memory locations. CVs allow you to adjust various decoder properties and customize your operating experience. The address, audio settings, motor control, lighting effects, and function assignments are just some of the properties you can adjust with CVs.
Page 11
All Aboard! CV. As the bit variables can take on only one of two values (0 or 1), they are usually used to control features that are either OFF or ON (i.e., disabled or enabled). Tip: Think of bits as light switches to turn ON or OFF various features. Each bit (0-7) carries a “weight”...
Page 12
All Aboard! Example Let’s assume we would like to set CV 29 (Configuration Data 1) so that 28/128 speed-step mode and extended (long) addressing are enabled. We would use the following steps to calculate the value: 1. To configure these features we see that bit 1 (F0) and bit 5 (EAM) should both be ON (set to 1), with all other bits OFF (set to 0).
All Aboard! Introduction to Programming Configuration Variable Control CVs This section details CV programming modes, reading CVs, CV 8: Manufacturer ID accessing indexed CVs, resetting CVs to factory defaults, CV 15: CV Unlock Code and locking and unlocking CVs. Due to the varying CV CV 16: CV Lock ID programming methods used by DCC systems, we cannot CV 30: Error Information...
Page 14
All Aboard! Indexed CVs The term “indexed CVs” tends to cause confusion and consternation. Simply put, indexed CVs are located on ‘pages’ to help manage the total number of CVs. This is required by the NMRA DCC Standard and works like this: Indexed CVs are accessed with the use of two CVs: CV 31 enables indexing when set to a value of 16 (the default value) and CV 32 selects the desired indexed page.
Page 15
The CVs can be quickly reset to their factory default values. Follow the steps below to perform either a full or partial CV reset: 1. Turn on track power to the decoder. If you have a SoundTraxx CurrentKeeper ™...
Page 16
If you still can’t identify the lock code, there may be a problem with the installation, programming track, or decoder. Contact SoundTraxx Customer Support if this occurs. If you do not have access to a programming track with read-back capabilities (or are uncertain...
The Primary address is commonly referred to as the “short” or “2-digit” address. Enter a value from 1 to 127 into CV 1 to set the primary address. All SoundTraxx decoders are set to primary address 3 by default. When selecting the locomotive with your DCC throttle, only enter “3” into the method used to select locomotives.
Basic Programming Configuring the Decoder CV 29 controls a variety of important settings. It determines Decoder Configuration CVs locomotive direction, speed-step mode, alternate power source, CV 29: Configuration Data 1 speed tables, and the decoder address. Configuring CV 29 This is the first CV that you’ll encounter which will need to be programmed by the bits. Refer to the “CV Programming Tutorial”...

Basic Programming Calibrating DDE Load Compensation Blunami features a cutting-edge new version of our already revolutionary Dynamic Digital Exhaust! We highly recommend you automatically calibrate Dynamic Digital Exhaust settings before adjusting throttle and braking control CVs. This will create an amazingly accurate representation of prototypical operation.
Page 22
Basic Programming Set the Independent Brake Rate The independent brakes on prototype locomotives are applied separately from the rest of the train, generally during switching operations and to control slack between units. CV 117 determines the deceleration rate that will bring the locomotive to a stop when the independent brake function is turned on.
Page 23
Basic Programming Setting the 3-Point Speed Curve By default, track voltage is distributed to the decoder with no variation in a straight line and the decoder responds instantly to the throttle setting. You can designate the amount of voltage applied at the first, middle, and last speed step with CV 2 (Vstart), CV 5 (Vhigh), and CV 6 (Vmid) to compensate for track power or throttle control inefficiencies.
Page 24
Basic Programming Setting the Custom Speed Table Blunami offers a custom speed table with 28 Table D. 28-Point Speed Table Settings adjustable speed points. The 28-point custom Value % of Throttle speed table is disabled by default. However, you can enable it with CV 25 (Speed Table Enable) and CV 29 (Configuration Data 1), and then adjust each speed point with CVs 67-94 (Custom Speed Table).
Page 25
Basic Programming Setting Motor Trim CV 66 (Forward Motor Trim) and CV 95 (Reverse Motor Trim) are used to “trim” the forward and reverse drive voltages when the 28-point custom speed table is enabled. Setting motor trim can help compensate for speed differences between forward and reverse directions. For instance, if the throttle setting is the same in both directions and the locomotive appears to be moving faster in reverse, you can use CVs 66 and 95 to correct the speed difference.
Basic Programming Lighting Output Control CVs Configuring Lighting Outputs CV 49: Headlight Configuration CV 50: Backup Light Configuration CV 51: FX3 Configuration Blunami provides up to eight lighting outputs (depending on CV 52: FX4 Configuration the board format). Lighting output control CVs allow you to CV 53: FX5 Configuration* enable Hyperlight effects, Grade-Crossing Logic, phase offset, CV 54: FX6 Configuration*...

Basic Programming Double-Flash Strobe The xenon double-flash strobe effect emits two rapid flashes of light during each flash rate timing cycle. CV 59 is used to modify the flash rate timing cycle. Western-Cullen D312 Rotary Beacon The Western-Cullen D312 Rotary Beacon effect follows a revolving reflector and bulb assembly flash-pattern.
Page 28
Basic Programming Phase Offset Add a value of 32 to the value of flashing Hyperlight effects to set the corresponding lighting output to Phase B from Phase A. Flashing effects set to Phase B will flash opposite of flashing effects set to Phase A, i.e., Phase A turns off when Phase B turns on, and Phase A turns on when Phase B turns off.
Page 29
Basic Programming Adjusting Lighting Output Settings After configuring Hyperlight effects and features with CVs 49-56, adjust CV 57 (Forward Direction Enable), CV 58 (Reverse Direction Enable), CV 59 (Hyperlight Flash Rate), CV 61 (Brightness Register 1), CV 62 (Brightness Register 2), CV 63 (Dimmer Level), and CV 64 (Master Brightness Register) to customize lighting output direction, the Hyperlight flash rate, and brightness levels.

DDE CV 2.507: DDE Traction Motor Low Volume Limit responds to this by elevating the volume of the CV 2.508: DDE Traction Motor High Volume Limit...
Page 49
Advanced Programming 6. Increase the throttle to an appropriate moderate speed for your layout (generally between speed-step 25 and speed-step 40). 7. When your locomotive is on level track, enter a value of 255 into CV 504 (DDE Load Slope) to automatically calibrate the nominal high-speed load level. Note: If, after the calibration is complete, you feel the need to increase or decrease the sensitivity, you can do this with CV 2.512.
Page 50
Advanced Programming CV 2.512 (DDE Load Sensitivity) is used to adjust the correlation between motor load and traction motor sound effects. As the motor is impeded during operation, the DDE processor and back-EMF circuitry will adjust the volume of traction motor sound effects according to the value of CV 2.512.

Advanced Programming Enabling Automatic Effects To provide more versatility, Flex-Map function mapping CVs allow you to configure automatic effects that respond to direction and movement. Follow the steps below to enable automatic effects with CVs 1.385-1.512 (Effect Auxiliary Map Registers): 1.
Page 55
Advanced Programming Flex-Map Function Mapping Examples The following examples detail using CVs 1.257-1.512 for function mapping, enabling automatic effects, and mapping an effect to the emergency stop button. Before accessing CVs 257-512, ensure CV 31 is set to a value of 16, and enter a value of 1 into CV 32. Example: Mapping Electric Functions You may want to use CVs 1.257-1.384 to map the grade-crossing signal to F4 and stop request bell to F9.
Page 56
Advanced Programming NMRA Legacy Function Mapping CVs 33-46 (Function Status CVs) are function mapping CVs stated in the NMRA Standards for DCC Configuration Variables (S-9.2.2). CVs 35-46 are used to assign effects to function keys F1-F12, and CVs 33 and 34 are used to assign effects to the F0 function key. If the same effect is selected for both reverse and forward F0 functions, that effect will turn on when the F0 function key is turned on regardless of locomotive direction.

Page 58
Advanced Programming Control Loop Coefficients Blunami compensates for load changes in response to back-EMF voltage readings that compare motor load to locomotive speed. When a variation between them occurs, a proportional-integral (PI) control loop adjusts the motor voltage to compensate for the difference so that the locomotive’s speed remains consistent.
Page 59
CV 215 may be programmed with any value from 60 to 255 to set the back-EMF reference Voltage from 6 to 25.5 volts. If you are planning to consist the model with other models equipped with SoundTraxx decoders (such as Tsunami or MC1 and MC2 DCC Mobile Decoders), make sure that the value entered in CV 215 is equal to the observed voltage of the track output from your command station, so that the reference voltage is identical to your other decoders.
