Lionel Specific CV Settings (continued)
CV29 supports the following (default is 18 decimal, 12 hex):
Bit 0 = Locomotive Direction: "0" = normal, "1" = reversed. This bit controls the
locomotive's forward and backward direction in DCC mode only.
Bit 1 = FL location: set to "0" in bit 4 to allow Speed and Direction instructions
control the FL, "1" = bit 4 in function group one instruction controls FL. The
recommended setting is“1”.
Bit 2 = Power Source Conversion: Set to"0" = DCC Capable Only
Bit 3 = Bi-Directional Communications: Set to "0", single direction communication.
Bit 4 = Speed Table: "0" allows speed table set by configuration variables #2,#5, and #6,
"1" = Speed Table set by configuration variables #66-#95. Must set to “1”, and
is only active in Speed Step 14 and 28 modes. The speed step profile in 128 speed
step mode is internally controlled.
Bit 5 = "0" = one byte addressing, "1" = two byte addressing (also known as extended
addressing) . Both modes are supported.
Bit 6 = Reserved for future use
Bit 7 = Accessory Decoder: "0" = Multifunction Decoder, "1" = Accessory Decoder, this bit
is set to “0”.
• Set CV29 to 18 (12 hex) for short locomotive address.
• Set CV29 to 50 (32 hex) for extended (long) locomotive address.
