10. OPTIONAL SA-K97U RS-232C INTERFACE BOARD
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, 1998, the VCR returns 30H, 39H, 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
“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-L911 model name in ASCII code.
L: 4CH, 9: 39H, 1: 31H, 1 31H
(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 5th byte
