9 OPTIONAL SA-K97U RS-232C INTERFACE BOARD
After transmitting the VISS SEARCH command (18), transmit the appropriate 2-byte numeric data (from 30H to 39H), the data input command
(40H), and either FF (ABH) or REW (ACH). All commands should be transmitted separately one byte at a time with "ACK" (0AH) confirmation
from the VCR after each transmission. * Execute in the Stop mode.
(18) VISS SEARCH (B3H)
The VCR starts search after returning "ACK". When the specified point is reached, the VCR returns COMPLETION (01H). If the end or
beginning of the tape is reached before the specified point, the VCR returns NOT TARGET (05H).
This command differs from commands (16) and (17) only in that the FF (ABH) or REW (ACH) command is included separately.
2 VCR setting commands
Commands available include control of recording/playback mode setting, timelapse VCR operation mode setting, date and time setting, timer
programming, on-screen setting, and others.
5 Recording/playback mode setting commands
Two commands are available. One allows you to rotate through recording/playback modes, the other permits you to directly select the
mode.
(1) MODE SHIFT (7DH) : Switches from one recording/playback mode to the next each time the command is transmitted. Use the TL
STATUS SENSE (D6H) command to check the current mode.
Transmit 1 byte at a time with "ACK" (0AH) confirmation from the VCR after each transmission.
(2) MODE (7EH) : Sets recording/playback mode directly.
After transmitting this command, transmit the appropriate 2-byte ASCII codes (from 30H to 39H) and the data
input command (40H). Correspondence of ASCII codes with recording/playback modes is as shown below.
Eg: To set to "24H".
