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, 1999, the VCR returns 30H, 36H, 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-9240 model name in ASCII code.
9: 39H, 2: 32H, 4: 34H, 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)”.
3rd byte
