3. 3 1 9999 Just like your house number each locomotive needs a unique address A handheld throttle set to the same address will send commands only to the specified locomotive That way your locomotive can be controlled without other locomotives listening in Each locomotive should have its own address As delivered from the factory each decoder always has the same default address Most users decide to use the locomotive number easily seen on the side of the locomotive as the address The address can be any number from 1 to 9999 CV2 Motor Starting Voltage 0 0 t0 255 This is the voltage applied to the motor in speed step 1 You can change this value so the locomotive receives a higher voltage at speed step 1 The default is 0 which means the motor starting voltage begins at 0 volts CV3 Motor Acceleration Rate 2 0t0255 Sets the rate of change of speed upon acceleration A higher value leads to a slower acceleration The default value of 2 means there is a couple of seconds of delay when the speed is increased A value of 0 or 1 is OK CV4 Motor Deceleration Rate 2 0t0255 Sets the rate of change of speed upon a decrease in throttle speed A higher value causes the stopping time to increase which leads to longer time before the locomotive eventually come to a stop The default value of 2 means there is a couple of seconds of delay when the speed is decreased If CV3 or CV4 are set to 0 or I a special failsafe feature is activated If y

Once the selection is made the motor starting voltage the acceleration rate and deceleration rate CVs are used to smoothly transition between each step However if these two CVs are both set to zero each speed step change will be abrupt and noticeable The 128 Speed Step Option can be considered direct drive where you have direct control of the locomotive speed CV2 and CV 3 and CV4 are used when in the 128 speed step mode When 128 speed step mode is in use CV5 and CV6 are not used You may change between the 128 speed step mode and 14 28 mode which is done at the throttle without reprogramming the locomotive decoder Failsafe Operation If your locomotive goes out of range of the throttle or the throttle is no longer transmitting you can set the locomotive to either continue running or stop after a preset amount of time The timer range is 0 5 seconds to 128 seconds A value of zero means the locomotive runs forever or until the battery runs down If CV11 0 this selects continuous operation In other words the locomotive continues to operate at the last received speed command forever The assumption is that it will eventually come back into range of the locomotive Another reason to use continuous running is because you want to control several trains with a single throttle Changing the throttle s address to control a new address means the original address 1s no longer being used This is the same as turning the throttle off or goin
