Decoder for Atlas N Scale H15/16-44 Locomotives				12
CV	Description		Range	Default
				Value**
57	Bit 3	Not used		0
	Bit 4	0 = No effect	0,1	0
		1 = Rear headlight functions as Gyro light		(16)
	Bit 5	0 = No effect	0,1	0
		1 = Rear headlight functions as Mars light		(32)
	Bit 6	0 = No effect	0,1	0
		1 = Rear headlight functions as single pulse		(64)
		Strobe light
	Bit 7	0 = No effect	0,1	0
		1 = Rear headlight functions as double pulse		(128)
		Strobe light
	Notes for CV57:
	Bits 4 to 7 of CV57 are effective if and only if CV51.0=1.
	Dimming is inactive if any of bits 4 to 7 are set to “1.”
	If more than one of Bits 4 to 7 of CV57 is set to “1,” only the highest
	numbered of these bits is effective.
58	Dimming for Output B (rear headlight)
	The value in CV58 is used to dim the rear headlight.
	Using the value “0” for this CV results in a completely
	dark rear headlight, when it is dimmed.
	Using the value “255” keeps the rear headlight at its
	maximum possible brightness, even when dimmed.

*The notation CVx.y = z means that bit y of CVx has the value ”z”. For example, CV29.2 = 0 means that bit 2 of CV29 has the value ”0.”

**In the Default Value field, the numbers shown in parenthesis () are the decimal values that must be written into a CV for the specified bit of that CV to have the binary value “1”.
