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 Sep., 14, 1999, the VCR returns 30H, 39H, 31H, 34H, 39H and 39H.)

(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

 

 

“30H – 39H” correspond with the numbers “0 – 9” (eg: 1234: 31H, 32H, 33H, 34H).

(4)

DEVICE TYPE (D1H)

: VCR returns the last 4 characters of the SR-9168 model name in ASCII code.

 

 

9: 39H, 1: 31H, 6: 36H, 8: 38H

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)
