5Date and time setting commands

(1)

DATE SET (8EH)

: Set the current date (month, day, year) for the VCR. After this command (8EH) is sent, input 1-

byte numerical data (30H — 39H).

(Example) June, 30, 1998

2-3 Commands for VCR status verification
(1)	DATE SENSE (BEH)	: The VCR returns the currently set month, day and year as 6 bytes. Each byte has a value of 30H to
		39H. 30H corresponds to 0 and 39H to 9.
		(Example: For June. 14, 1998, the VCR returns 30H, 36H, 31H, 34H, 39H and 38H.)
(2)	TIME SENSE (BFH)	: The VCR returns the currently set hour, minute and second as 6 bytes. Each byte has a value of
		30H to 39H. 30H corresponds to 0 and 39H to 9.
		(Example: For 15:30:45, the VCR returns 31H, 35H, 33H, 30H, 34H and 35H.)
(3)	COUNT CODE (D0H)	: VCR returns the counter data beginning with the 4th digit from the right in 4 bytes. ASCII codes
(4)	DEVICE TYPE (D1H)	“30H – 39H” correspond with the numbers “0 – 9” (eg: 1234: 31H, 32H, 33H, 34H).
		: VCR returns the last 4 characters of the SR-L910 model name in ASCII code.
		L: 4CH, 9: 39H, 1: 31H, 0: 30H
(5)	VTR INQ (FBH)	: Used to make sure that the connected unit is the VCR. The VCR will return “ACK” (0AH).
(6)	PL/AL COUNT SENSE (D5H)	: VCR will return a total of 6 bytes. The first 3 bytes show the number of alarm inputs in 3 digits and
		the last 3 bytes show the number of power losses in 3 digits. ASCII codes “30H – 39H” correspond
		with the numbers “0 – 9” (eg: 123 alarm inputs and 45 power losses: 31H, 32H, 33H, 30H, 34H,
		35H).
(7)	HOUR METER SENSE (D2H)	: VCR returns the hour meter data in 5 bytes. (eg: 12345 hours: 31H, 32H, 33H, 34H, 35H).
(8)	TL STATUS SENSE (D6H)	: VCR returns Timelapse mode data in 6 bytes. The contents of each byte are as follows:

1st/2nd byte Recording/playback mode Correspondence of the code and the mode is the same as that described in “2-2 Recording/playback mode setting commands (2) MODE (7EH)”.

5Timer programming commands

(1)	PRG/CLK (62H)	: Engages timer programming mode.
(2)	SHIFT → (–) (64H)	: Selects setting items. (–)
	SHIFT ← (+) (63H)	: Selects setting items. (+)
(3)	SET – (66H)	: Sets data selected with SHIFT.
(4)	SET + (65H)	: Sets data selected with SHIFT.
	CANCEL (67H)	: Cancels program data in timer programming or engages the Cancel Program mode.
Setting procedure is the same as when using the VCR controls. Be sure to transmit commands 1 byte at a time with “ACK” (0AH)

5On-screen setting command

(1)	ON SCREEN ON (70H)	: Activates time/date on-screen indication.
	ON SCREEN OFF (71H)	: Deactivates on-screen indication.
Setting procedure for the following command (2) is the same as when using the VCR controls. Be sure to transmit commands 1 byte at a
time with “ACK” (0AH) confirmation from the VCR after each transmission.

(2)ON SCREEN SELECT (74H) : Changes the time display position on screen.

5Other commands

(1)	AL/PL RESET (E1H)	: When transmitted during alarm recording, the recording mode switches back to the previous mode.
		The VCR’s “AL” indication goes off. Transmit again after “AL” indicator goes off to reset the alarm/
		power loss memory.
(2)	COUNT RESET (E2H)	: Resets the tape counter to “0000”.

4th byte		6th byte
Conditions of each setting		Types of warnings
BIT	Status when BIT is “1”.	HEX.Data	Types of warnings
0	Alarm recording is in progress.	0	No abnormality
1	ALARM REC function is ON.	1	Loading error
2	Not defined. Always 0.	2	Unloading error
3	Sensor recording is ON.	3	Supply reel error
4	External recording function is ON.	4	Drum error
5	Always 0.	5	Take-up reel error

* Operation with commands from the RS-232C is accepted
even in the Operation Lock mode.
