Atlas 520099 manual Brake momentum on DC operation, Lighting Effects for Output a front headlight

Decoder for Atlas N Scale H15/16-44 Locomotives					10
CV	Description			Range	Default
					Value**
50	Bit 2	Brake momentum on DC operation.		0,1	0
		Used to achieve prototypical braking at red			(4)
		signal indications if conventional DC control
		is disabled. (CV29.2 = 0*)
		0	= locomotive proceeds with track-voltage-
		dependent speed inside the conventional DC
		section.
		1	= locomotive brakes in the conventional DC
		section with preset brake momentum.
	Bit 3	Motor Drive Selection		0,1	0
		0	= Precision Glide Control
		1	= Silent Drive		(8)
	Bits	Not used			0
	4-7
51	Lighting Effects for Output A (front headlight)			0-247	6
	Bit 0	Directional or Independent Headlights:		0,1	0
			0 = Headlights are directional.		(1)
			1 = Headlights are independent per Rule
		17, with F0 controlling front headlight and F1
		controlling rear headlight.
	Bit 1	Front Headlight Dimming Control:		0,1	1
		If CV51.2=1, the value in CV52 is used for			(2)
		front headlight dimming with the dimming
		controlled as follows:
		CV51.1=0: Front headlight always dimmed
		CV51.1=1: If CV51.0=0, function F1 dims
		front headlight; if CV51.0=1, function F4 dims
		front headlight.
	Bit 2	Dimming of Front Headlight:		0,1	1
		0	= Front headlight cannot be dimmed		(4)
		1	= Front headlight can be dimmed
	Bit 3	Not used			0
	Bit 4	0	= No effect	0,1	0
		1	= Front headlight functions as Gyro light		(16)
	Bit 5	0	= No effect	0,1	0
		1	= Front headlight functions as Mars light		(32)
	Bit 6	0	= No effect	0,1	0
		1	= Front headlight functions as single pulse		(64)
		Strobe light
	Bit 7	0	= No effect	0,1	0
		1	= Front headlight functions as double pulse		(128)
		Strobe light
