Sony MDS-S50 Higher Bits Lower Bits Hexa Details, Bit When Binary, Hexadecimal Binary

MDS-JE470

Reading the Display:

Convert the hexadecimal display into binary display. If more than two causes, they will be added.

Example

When 42 is displayed:

Higher bit : 4 = 0100 t b6

Lower bit : 2 = 0010 t b1

In this case, the retry cause is combined of “CLV unlock” and “ader5”.

When A2 is displayed:

Higher bit : A = 1010 tb7+b5

Lower bit : 2 = 0010 t b2

The retry cause in this case is combined of “access fault”, “IVR rec error”, and “ader5”.

Bit	b7	b6	b5	b4	b3	b2	b1	b0		When 0		When 1
Binary	0	0	0	0	0	0	0	1	01	Emphasis OFF		Emphasis ON
	0	0	0	0	0	0	1	0	02	Monaural		Stereo
	0	0	0	0	0	1	0	0	04	This is 2-bit display. Normally 01.
	0	0	0	0	1	0	0	0	08	01:Normal audio. Others:Invalid

	0	1	0	0	0	0	0	0	40	Copyright		No copyright
	1	0	0	0	0	0	0	0	80	Write prohibited		Write allowed

Reading the Display:

Convert the hexadecimal display into binary display. If more than two causes, they will be added.

Example When 84 is displayed: Higher bit : 8 = 1000 t b7 Lower bit : 4 = 0100 t b2

In this case, as b2 and b7 are 1 and others are 0, it can be determined that the retry cause is combined of “emphasis OFF”, “monaural”, “original”, “copyright exists”, and “write allowed”.

Example When 07 is displayed: Higher bit : 0 = 1000 tAll 0 Lower bit : 7 = 0111 t b0+b1+b2

In this case, as b0, b1, and b2 are 1 and others are 0, it can be determined that the retry cause is combined of “emphasis ON”, “stereo”, “original”, “copyright exists”, and “write prohibited”.
