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 Configuration 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.
