Athearn Caboose Decoder

Full manual attached as PDF

 No flicker circuitry keeps lights from flickering on dirty track
 6 function outputs,each have lighting effects generators
 Select from 14 different lighting effects
 Built in support for LED lighting
 Simplified function mapping to all functions F0-F28
 Decoder programming lock mechanism
 Support for all forms of programming

CV1 Short decoder address; 1-127 valid
CV7 Decoder version number. This decoder is 1
CV8 Manufactuer ID. NCE = 11
CV8 Set this CV to 8 on the programming track and the decoder will reset to factory settings.
CV11 Packet timeout value (in ½ second increments) Time the decoder will wait before braking to a
stop after running into a section of track with DC power. 0=Don’t brake
CV15 Decoder programming lock “KEY”. This CV is always programmable even when “locked”
CV16 Decoder programming lock ID. When CV15=CV16, programming is unlocked and the
decoder will respond to programming commands. If CV15 is not equal to CV16 then
decoder programming is locked and it will not program (except CV15) or read.
CV17 High byte of long (4 digit) address
- bit 6,7 always= 1
- bits 0-5 are upper 6 bits of address
CV18 Low byte of long (4 digit) address
CV19 Consist address. (0 or 128 = no consist active)
- bits 0-6 short consist address (1-127 valid)
- bit 7 0= direction is normal, 1= direction is reversed
CV21 Functions active in consist mode. Bit 0 =F1, Bit 7=F8
CV22 Functions active in consist mode. Bit 0,1 controls F1,bit 2=F9, bit 2=F10,bit 3=F11, Bit 4+F12.
- 1=function can be controlled at consist address, 0 = no consist control
each bit 1=function can be controlled at consist address, 0 = no consist control
CV29 - bit 0 1= direction of operation is reversed, 0= direction is normal
- bit 2 1= analog operation mode enabled, 0 = disabled
- bit 5 1= use long address in CV17/18, 0= use short address CV1
- bits 1,3,4,6,7 are ignored by the decoder
CV130-CV153 Effects configuration registers for outputs 1-6
CV161 Outputs on in DC mode
CV162 Ditch light hold time (in seconds)
CV NOTES: All CV numbers not listed above are ignored. This decoder supports all DCC programming
