3 Commands for VCR status verification

 

 

When the command is sent, the VCR returns the corresponding information.

 

(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.

 

(2)

TIME SENSE (BFH)

(Example: For Oct., 14, 1998, the VCR returns 31H, 30H, 31H, 34H, 39H and 38H.)

: 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.

(3)

COUNT CODE (D0H)

(Example: For 15:30:45, the VCR returns 31H, 35H, 33H, 30H, 34H and 35H.)

: 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-9080 model name in ASCII code.

(5)

VTR INQ (FBH)

 

39H, 30H, 38H, 30H

 

 

 

: 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,

(7)

HOUR METER SENSE (D2H)

35H).

 

 

: VCR returns the hour meter data in 5 bytes. (eg: 1234 hours: 31H, 32H, 33H, 34H).

(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 MODE (7EH) (see page 59).

* When an error occurs in the VCR and the Warning mode is engaged, the third bit of the second byte sent back with the STATUS

SENSE (D7H) is set to “1”, showing the warning status.

 

In this case, release the warning via the RS-232C with the CLEAR (56H).

To release it on the VCR, turn the [OPERATE] button

off and on again.
