Decoder firmware version 2.0 CV list

CV1 normal 7 bit loco (short) address; 1-127 valid
CV2 vstart, value added to all speed steps of "standard speed table", 1 count =
.89% of full voltage when using the normal speed table. If 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.
CV23 is added to this value on power up]
CV4 deceleration rate (each unit = 32mS between speed steps) 254 max.
CV23 is added to this value on power up
CV7 Manufactuer ID. North Coast = 11
CV8 Decoder version number. This decoder is 16 which means ver. 1.6
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 high byte of 14 bit address
bit 6,7 always= 1
bits 0-5 are upper 6 bits of 14 bit address
CV18 low byte of 14 bit address (lower 8 bits)
CV19 8 bit address for consist, when active the consist responds to all
commands addressed to it the same as it would to it's normal 8 or 14 bit
address. Note: the normal 8/14 bit 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 then the consist is inactive.
bits 0-6 7 bit consist address (1-127)
bit 7 0= direction is normal, 1= direction is reversed
CV23 acceleration rate adjust (each unit = 32mS between speed steps) this
value is added to the value in CV3 at power up or when reprogrammed
CV24 deceleration rate adjust (each unit = 32mS between speed steps) this
value is added to the value in CV4 at power up or when reprogrammed
CV29 - 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= DC conversion enabled. 0 = disable DC mode
- bit 3 not used
- bit 4 1= use alternate (uploadable) speed table, 0= use normal
speed table
- bit 5 1= use 14 bit address in CV17,18 (do not use CV1),
0= use CV1 not CV17,18
- bit 6 not used
- bit 7 not used
CV64 - Headlight configuration, 0=normal, 1=Headlight acts as a Mars light
UPLOADABLE SPEED TABLE VARIABLES
CV66 Speed step 0 of uploadable table (Must be 0 for proper operation
CV67-CV94 Speed step 1 to 28 of uploadable speed table
