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) : To search for a designated alarm-input point on the tape.
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 sett
ing, timer
programming, on-screen setting, and others.
5Recording/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 “L24H”.

5Date and time setting commands
(1) DATE SET (8EH) : Set the current date (month, day, year) for the VCR. After this command (8EH) is sent, input 1-
byte numerical data (30H
— 39H).
(Example) Oct., 30, 1998
(2) TIME SET (8FH) : Set the current time (hour, minute, second) for the VCR.
After this command (8FH) is sent, input 1-byte numerical data (30H
— 39H).
(Example) 15 hours, 29 minutes, 59 seconds

5Timer programming commands
(1) PRG/CLK (62H) : Engages timer programming mode.
(2) SHIFT – (64H) : Selects setting items. (–)
SHIFT + (63H) : Selects setting items. (+)
(3) SET – (66H) : Sets data selected with SHIFT.
SET + (65H) : Sets data selected with SHIFT.
(4) CANCEL (67H) : Cancels program data in timer programming or engages the Cancel Program mode.
Setting procedure is the same as when using the VCR controls. Be sure to transmit commands 1 byte at a time with
“ACK” (0AH)
confirmation from the VCR after each transmission.
5On-screen setting command
(1) ON SCREEN ON (70H) : Activates on-screen indication.
ON SCREEN OFF (71H) : Deactivates on-screen indication.
Setting procedure for the following command (2) is the same as when using the VCR controls. Be sure to transmit commands 1 byte
at a
time with “ACK” (0AH) confirmation from the VCR after each transmission.
(2) ON SCREEN SELECT (74H): Switches the on-screen display items.
POS V+ (73H): Moves the on-screen indication in the vertical direction.
POS H+ (75H): Moves the on-screen indication in the horizontal direction.
5Other commands
(1) AL/PL RESET (E1H) : When transmitted during alarm recording, the recording mode switches back to the previous mode.
The VCR’s “AL” indication goes off. Transmit again after
