BASIC PROGRAMMING NOTES (continued)
As soon as you have programmed CV99, the value of CV99 will be
transferred into CV317. When the programming is nished, CVs 96, 97,
and 99 will be set back automatically.
This procedure is ONLY needed when programming CVs above 255 on
some older Digitrax DCC systems.
NOTE: Please make sure that index CV32 is set to 1 and Index CV31 is
set to 16 before you change any of the individual sound volume CVs.
Please refer to the decoder manual as necessary for additional CV
information. CVs 31 & 32 are not required to adjust the Master Volume,
CV63.
Below are some of the basic information points about the V5 decoder
and its capabilities:
From the factory the model is set to default DCC address 03
• The decoder can be set to a 2 or 4 digit address with normal
addressing on all DCC systems.
• Supports CV1 Short Address 1-127
• Supports CV17/18 Long Address 128-9999. Please add 32 to
the default value in CV29 Conguration for the decoder to
recognize a four-digit address and other cong settings.
• Supports NMRA Consisting using CVs 19 (consist address),
CV21 (consist function control F1 to F8), CV22 (FL and F9 to
F12 (FL is F/R directional headlight).
• The decoder may be reset on the program track by setting CV8
= 8. NOTE: See important information on decoder resets in the
CV8 Resetting the Decoder section.
• Manufacturer’s ID: CV8 = 151
• ESU has added additional function button capabilities (see
Function Chart) that may be controlled in a consist using CV109
(F15 to F22) and 110 (F23 to F30). CV109 programs the same
as CV21, CV110 (the same as CV22 in regards to bit values).
CV2 Start Voltage (Vmin or Vstart)
Sets the minimum speed or voltage applied to the motor on throttle
speed step 1. This can be customized to preference but is generally set
where the locomotive will either almost move consistently at SS1 or will
crawl on SS1. A setting between 1 to 3 is common.
CV3 Acceleration Rate
Sets the amount of time it will take for the decoder to apply the max
voltage set by CV5 to the motor speeding up. The setting in CV3 is
multiplied by 0.896 seconds to calculate the time. The CV range is 0
to 255.
CV4 Deceleration Rate
Sets the amount of time it will take for the decoder to reduce the
max voltage set by CV5 to zero when stopping. The setting in CV4 is
multiplied by 0.896 seconds to calculate the time. The CV range is 0
to 255.
CV5 Maximum Voltage (Vmax, Vfull)
Sets the maximum speed that the locomotive will move. If one model
runs faster than another at full throttle, reducing CV5 on the faster
locomotive so that they are closer in speed will allow you to run
differing locos together. The CV range is 0-255 with 255 applying the
maximum voltage the decoder can supply to the motor. CV5 must
always be greater than CV6 to prevent erratic operation.
CV6 Midrange Voltage (Vmid, Vhalf)
Sets the midpoint of the speed range. A lower setting in CV6 will have
smaller increases in speed (voltage to motor) from Vstart to Vmid with
throttle speed step advances. Once you reach the Vmid set voltage,
larger increases will occur from Vmid to Vmax as you advance the
throttle.
