CV1 Short address. Valid values range from 1 to 127.
CV2 Vstart. This value added to all speed steps of the "factory speed table", 1 count = about 1% of full
voltage when using the normal speed table. If the uploadable speed table is used the percentage
varies with the frequency of PWM motor control in CV9.
CV3 Acceleration rate (each unit = 32mS between speed steps) 254 max. Available in 14/28 speed
CV4 Deceleration rate (each unit = 32mS between speed steps) 254 max. Available in 14/28 speed
CV9 PWM frequency. This CV determinesthe total PWM period for the uploadable speed table. Each
unit = 128uS this allows a frequency of 30hz to 279hz. 279hz comes from using each speed = 1
count this yields: max speed = 28*128us for a 3.58mS period which equals 279hz.
CV17 Long address high order 6 bits
bit 6,7 always= 1
bits 0-5 are upper 6 bits of 14 bit address
CV18 Long address low order byte
CV19 Consist address. 8 bit address, when active the consist responds to all commands addressed to
it the same as it would to it's normal long/short address. Note: the normal long/short address is still
active for all non-speed/direction commands (especially useful for headlight and other function
controls of individual locomotives while in consist). If the consist address is set to 0 or 128 then the
consist is inactive.
bits 0-6 7 bit consist address (1-127)
bit 7 0= consist direction is normal, 1= consist direction is reversed
CV23 Acceleration adjust. This value is added to the value in CV3 at power up or when reprogrammed
CV24 Deceleration adjust. This value is added to the value in CV4 at power up or when reprogrammed
CV29 Decoder Configuration byte
- bit 0 1= direction of operation is reversed, 0= direction is normal
- bit 1 1= use 28 speeds mode, 0= 14 speed mode
- bit 2 1= Analog conversion enabled. 0 = disable analog mode
- bit 4 1= use alternate (uploadable) speed table, 0= use normal speed table
- bit 5 1= use long address (CV17,18) do not use CV1, 0= use short address CV1 not CV17,18
- bits 3,6 and 7 are not used
UPLOADABLE SPEED TABLE CVs
CV66 Speed step 0 of uploadable table (Must be 0 for proper operation)
CV67-CV94 Speed step 1 to 28 of uploadable speed table
