1. The Loadable Speed Table consists of 28 data points contained in CVs 67 through 94 each defining the percentage of motor voltage applied at a given speed step Each data point can contain a value of 0 to 255 corresponding to 0 to 100 of 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 the decoder 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 To create a speed curve begin by assuming that the decoder will be operated in 28 speed step mode Don t worry if you are using another mode your decoder will automatically take care of the translation between modes 1 Start by making a table containing 28 entries one entry for each speed step 2 Foreach entry record the desired throttle response as a percentage of full speed i e 0 to 100 MCI Series Mobile Decoder Users Guide Table C Calculating the User Loadable Speed Table CV Speed Full CV Step Speed Value Page 15 3 Compute and record the2. and F 11 CV 22 2 16 18 Consist lnertia Control CVs 23 and 24 can be used to increase or decrease the locomotive s acceleration and braking response whenever it is part of a consist i e CV 19 is programmed with a valid address CV 23 controls the consist acceleration rate and CV 24 controls the consist braking rate When the consist address is active a new acceleration rate is calculated by adding the value in CV 23 to the baseline acceleration rate in CV 3 Similarly a new braking rate is calculated by adding CV 24 to the baseline braking rate in CV 4 When the consist address is set to 0 CV 23 and 24 have no effect Both CV 23 and 24 may be set to any value between 127 and 127 A positive value will produce a slower throttle response while a negative value will result in a quicker throttle response If the sum of consist and baseline rate exceeds 255 then the final rate is set to the maximum value of 255 If the sum of consist and baseline rate is negative then the final rate is set to the minimum value of 0 To set a positive value simply program the CV with the desired number between 0 and 127 To set a negative value first change the sign of the value back to positive and then add 128 Thus to set 5 program the CV with 5 128 133 Note that a setting of 128 is the same as 0 and has no effect MCI Series Mobile Decoder Users Guide Page 19 Step 5 Function Mapping Function Mapping Table Function Mapping

4. Explained Function mapping allows the decoder to be reconfigured so that function outputs can respond to a different function key input This is especially useful for users who have throttles with less than six function keys as now they can pick and choose what effects they can control instead of being restricted to an arbitrary assignment There are 14 function mapping CVs twelve CVs 35 46 are used to assign output control to function keys 1 through 12 respectively The other two CVs 33 and 34 are both for the FO function CV 33 controls which outputs are on when FO is on and the locomotive is moving forward CV 34 controls which outputs are on when FO is on and the locomotive is moving in reverse If the same output is selected in both CV 33 and CV 34 that function will turn on when the FO function is on regardless of locomotive direction Not all keys can control all outputs or effects The table below shows which functions can be mapped to which outputs Note that a function key can be set up to control more than one output gt aS KA F a a a a ala la o a a O S Ww Ww Ww LI LI LI LLI Ww Ww LI c at dD gt gt gt gt gt gt gt gt gt gt o D S tc tc ir i se fee Tu o ic D 5 z Wi W W W W W m E W W 2 W 7 gt no p ro 79 p Je N g p 7o 1 p o LI LI Ww LI Lu LI

7. resembles a burning fire and can be used with a lamp placed in the firebox area The effect is improved when two lights are used one yellow and one red or orange and each connected to a separate function output Dyno Light This effect for steam locomotives synchronizes the lamp brightness to the output of the dynamo such that the lamp brightness gradually increases as the dynamo builds up speed Phase Select Alters the timing of the effect so that it is 180 degrees out of phase with the other effects This allows you to have two light effects that blink back and forth if desired Set one effect to phase A and the other to phase B Grade Crossing Logic Causes the lighting effect to become active only when function 2 has been activated and the corresponding lighting function key is also on A typical use would be to cause the ditch lights to flash at a grade crossing The grade crossing logic can be used with almost all the Hyperlight effects The on off dimmable headlight Dyno Light FRED exhaust flicker and firebox flicker effects will not be affected The other effects will either turn off strobes and beacons or revert to a steady on state mars light ditch lights etc as appropriate to prototype practice Rule 17 Headlight Operation Converts the headlight and backup light to independent non directional functions When enabled the headlight is controlled as if it were FX5 Function 5 and the backup light as FX6 Fun
8. step 20 3 Adjust the value in CV 209 Kp with increasingly higher values just until you begin to notice some jerkiness in the locomotive speed Reduce the setting in CV 209 to the value just before the jerkiness started 4 Adjust the value in CV 210 Ki with increasingly higher values until you begin to notice some oscillation in the locomotive speed whenever the throttle setting is changed Reduce the setting in CV 210 to the value just before the oscillation started Note When using load compensation it is unnecessary to set large values into CV 2 Start Voltage This is because the load compensation algorithm will automatically adjust the motor power up to reach desired throttle setting Therefore CV 2 can usually be set to 0 when load compensation is enabled Setting the Load Compensation Curve Your decoder provides two degrees of freedom for controlling the amount of load compensation applied to the motor over the throttle range using CV 10 Back Emf Cutout and CV 212 Back Emf Feedback Intensity CV 212 sets the amount of load compensation that is initially applied to the motor and may be set anywhere between 0 and 255 A value of 0 disables load compensation altogether while a value of 255 corresponds to full 100 compensation CV 10 Back Emf Cutout determines the degree by which the load compensation is reduced as the throttle speed is increased When CV 10 is set to 0 the amount of load compensation set by CV 212 is
9. the value programmed in CV 4 which has the effect of slowing the train more gradually than by simply turning the throttle down Values of 129 thru 255 translate to 1 thru 127 which have the opposite effect as they subtracted from the setting in CV 4 and slow the train more aggressively than turning the throttle down as a brake would be expected to do Be careful not to set F11 too high if you do the net braking rate will be zero and you will have effectively turned F11 into an emergency stop button Note that setting CV 61 to a value of 0 or 128 has no effect on the brake rate and basically disables this feature MCI Series Mobile Decoder Users Guide Page 30 111 Troubleshooting Troubleshooting If you should have any difficulties with the operation of your SoundTraxx Mobile Decoder first check this section for hints on trouble shooting We have found that most problems are caused by an errant CV value and are easily corrected When all else fails try resetting the CV values back to their defaults see the section Basic Programming and try again Locomotive doesn t run but was working Address has been accidentally changed Consist address CV 19 was accidentally set CV 29 has been changed to select other address Acceleration and braking CVs set to very high values Broken motor wire or track pickup wire Tip Check the decoder s Pilot Light to confirm presence of track power Locomotive never ran See all the abo
