1 INTRODUCTION

1-1 Major Features

5 40-hour long-time recording with a 160-minute tape

Recording times are selectable from 8 hours (EP mode) and 24/40 hours (High-density Timelapse mode). Monitor image recording for up to 40 hours is possible with a 160-minute tape.

5 Audio monitoring

Audio signals can be recorded in the 24-hour/40-hour Timelapse mode, as well as in the conventional 8-hour mode. This strengthens surveillance capabilities by providing both audio and video information.

5 Alarm recording function

When an alarm signal is input in the Timelapse Record mode, the 8-hour (EP) mode is automatically engaged. Alarm recording time can be selected from 5, 15, 30, 60, 120, or 180 sec., to tape end or set manually.

An index code is automatically recorded when alarm recording

starts. Used as an alarm cue signal, this allows quick access to alarm recording points with the Index Search function.

5 Sensor recording

Whenever an alarm signal is input in the Stop mode, the Record mode is automatically engaged.

5 Time/date generator

Superimposes the year, month, date, minute and second on the image during recording. Also allows you to use the menu screen to display the number of alarms, alarm time, and the number of the power failures.

5 Timer recording function

Two types of timer recording are available: based on the date (up to 8 programs) or based on the day of the week.

5 Recording Check function

Pressing the [REC CHECK] button during recording allows you to check the status of the recording in progress. When activated via the corresponding function menu switch, the builtin head cleaner automatically cleans the heads whenever inferior picture quality is detected during Recording Check. After cleaning, the Recording Check operation is executed again automatically (Auto Recording Check function).

5 Operation lock system

To prevent accidental or deliberate interference with VCR operation, the operation lock system is provided.

5 Warning function

Error indications are shown on the front panel display.

5 Power-off video throughput function

Even when the power is off, the camera's EE input can be output from the VCR.

5 Camera switching signal output terminal 5 Automatic re-start of recording after a power failure 5 Digital hour meter display 5 Repeat recording/series recording function 5 Recording control with external activation signal 5 Alarm recording, tape end and warning electronic buzzer 5 Summer time compensation function 5 Wired remote control (optional) 5 RS-232C control (with optional SA-K97U RS-232C interface

board installed)

The SR-L911US can be controlled via a personal computer. Operation status can be monitored on the computer.

5 Shuttle ring provided 5 One-touch time search/alarm search button

1-2 Periodical Maintenance

This VCR incorporates precision mechanical parts which will collect dirt over time and ultimately deteriorate and wear out. Over long periods of use, dirt and dust accumulates on the heads, drums and tape transport mechanisms. Dust which penetrates the VCR (especially during outdoor use) also promotes the wear and deterioration of mechanical parts by causing poor contact between tape and heads. This also prevents the VCR from maintaining video and audio quality at high levels. To prevent wear and deterioration, clean the heads regularly using a head cleaning tape. However, because a head cleaning tape alone cannot clean the entire tape transport mechanism, this should also be inspected periodically to prevent any problems that could result from a sudden failure.

As replacement and adjustment of parts require advanced skills and specialized equipment, please contact the person in charge of professional video equipment at your nearest JVC-authorized service agent for servicing.

Monitoring Usage Time

The total operation time reached by an ordinary home VCR in 5 or 6 years may be reached by a professional VCR in as few as 5 or 6 months. Therefore, it is important that the total hours of operation be carefully monitored. An hour meter in the on-screen display (see page 16) shows the accumulated time. In the chart below, the hours accumulated in each month are shown in relation to the number of hours used per day. Times shown inside shaded area indicate that maintenance should be performed.

Usage time per day

1-3 Precautions

Handling and storage place

1 INTRODUCTION

5 Avoid using the unit in places subject to the

following conditions:

• extreme heat or cold

• strong magnetic fields (do not use a transceiver within 2 meters of this unit)

• high humidity

• dust and soil

• vibrations

• variations in temperature

5 Use this unit in horizontal (flat position) only. 5 Do not leave the unit in the Still or Record Pause

mode for a long time as this may damage the tape.

To minimize tape damage, this VCR automatically

enters the Stop mode after about 5 minutes have passed in the Still or Record Pause mode.

Condensation

5 Condensation

When cold beer is poured into a glass, water drops appear on the glass’s surface. This phenomenon is called “condensation”. When condensation occurs on the VCR’s head drum and tape guides it may damage the tape.

5 Handle the unit carefully

• Do not place anything heavy on the unit (a monitor, etc.). A malfunction may occur.

• Do not put any foreign substance into the cassette loading slot.

• Avoid violent shocks to the recording chassis during transportation. Remove the cassette tape from the unit for transportation.

5 Turn off the power to save electricity when not using the

unit.

5 Condensation occurs in the

following cases.

• When the VCR is moved from a cold place to a warm place.

• In a room that has just been heated or in an area directly exposed to a cooler.

• When there is excessive humidity

Head drum

Video tape

5 When condensation is expected to occur

Turn the power of the VCR on before use.

Video cassette

Erasure prevention tab

Timelapse recording is performed over very long periods of time which means that a durable tape is required.

• Use a T-160 tape or shorter.

• Do not use extended tapes (180 minutes or longer such as T-180).

1-4 Daily Inspection

Although this unit has been designed for reliable operation over a long period of time, a daily inspection is recommended to ensure optimum performance. In particular, be sure to check the repeat recording function on a daily basis.

Inspection procedure

Turn on the power for all units connected to the surveillance system.

Check the quality of the image shown on the monitor.

Check that the date and time shown on the monitor are correct.

• Only use video cassette bearing the mark.

• To prevent accidental erasure of a recorded tape, break the erasure prevention tab on the cassette. To use a cassette with a broken tab, place a piece of cellophane tape over the broken tab.

• Video cassettes cannot be used upside down.

• Leaving the tape in a partially wound condition for a long time may damage the tape. Rewind the tape to the beginning before storage.

Rewind the tape recorded the previous day for several seconds.

Press the play button for playback.

Check that the playback picture is normal.

Check that the recorded date and time are correct.

• This unit includes a Recording Check function (using the [REC CHECK] button) and an Automatic Recording Check function for daily checking of recording quality.

If any problems are found after inspection, turn the power off, unplug the power plug from the AC outlet, and contact your JVC dealer.

10-3. SA-K97U RS-232C Protocol & Commands

This section provides technical data for programmers.

Command description

To use the commands described in the following pages, prepare the VCR for communications as follows:

Transmit the command “JVC TABLE 1 ON” (F6H) to the VCR. The VCR will return “ACK” (0AH). The VCR can now receive any command described in this section. To cancel the communications mode, transmit the command “JVC TABLE 1 OFF” (F7H).

2-1 VCR control commands

Commands (1) through (12) are 1-byte commands. The VCR will return “ACK” (0AH) when the command is received. Confirm that “ACK” (0AH) has been returned before transmitting the next command.

(1) OPERATE ON (7BH) : VCR operating mode is turned “ON”.

OPERATE OFF (7CH) : VCR operating mode is turned “OFF”. (2) PLAY (3AH) : Playback (3) STILL (4FH) : Pause/Still (4) STOP (3FH) : Stop (5) FF (ABH) : FF/Forward search in the Play mode. (INDEX Search when Menu switch <INDEX SEARCH> is set

(6) REW (ACH) : REW/Reverse search in the Play mode. (INDEX Search when Menu switch <INDEX SEARCH> is

(7) REV PLAY (4AH) : Reverse playback at normal speed (8) TIMER ON (60H) : Timer “ON”

TIMER OFF (61H) : Timer “OFF” (9) OPE LOCK ON (69H) : Operation lock “ON”

OPE LOCK OFF (6AH) : Operation lock “OFF” (10) EJECT (A3H) : Cassette ejection

(11) F-FIELD STEP (ADH) : Engages field advance in the normal/reverse direction when the VCR is in the Still mode. The tape

R-FIELD STEP (AEH) is advanced by one field in the 8H/Timelapse mode.

(12) REC CHECK (C1H) : Engages REC CHECK. (function is the same as when locally controlled on the VCR.)

to ON.)

set to ON.)

VCR returns “ACK”, and then returns CASSETT OUT (03H) after cassette has been ejected.

If the VCR is in any other mode, the Still mode is engaged.

Before transmitting either of the following commands ((13) or (14)), first transmit REC/DUB REQUEST (FAH), and confirm that “ACK” is returned by the VCR.

(13) REC (CAH) : Starts recording. The VCR returns “ACK”. (14) REC PAUSE (CBH) : Engages Record-Pause mode. The VCR returns “ACK”.

However, if the loaded cassette’s safety tab has been removed, recording is not possible regardless of the fact that “ACK” has been returned. Use the STATUS SENSE (D7H) command to confirm tape status. (See Section 2-3 (9)).

After transmitting commands VISS FWD (15) or VISS REV (16), transmit the appropriate numeric data (1-byte ASCII codes from 30H to 39H) and the data input command (40H). ASCII codes “30H – 39H” correspond with the numbers “0 – 9” (ie.: 0: 30H, 1: 31H, ... 9: 39H). Each byte of numeric data and the data input command should be transmitted separately with “ACK” (0AH) confirmation from the VCR after each transmission. The VCR’s Menu switch <INDEX SEARCH> is set to OFF.

(15) VISS FWD (B0H) : To advance the tape in the forward search mode to the designated alarm-input point. The alarm

(16) VISS REV (B1H) : To reverse the tape in the reverse search mode to the designated alarm-input point. The alarm

Eg: To search for the 3rd alarm-input point from the current position.

TXD RXD

The VCR starts INDEX 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). (Sending either the 30H,30H or 30H,31H command will cause the VCR to search for the 1st alarm-input point).

Page 48

After transmitting the VISS SEARCH command (17), 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.

(17) VISS SEARCH (B3H) : To search for a designated INDEX point on the tape.

The VCR starts INDEX 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 (15) and (16) only in that the FF (ABH) or REW (ACH) command is included separately.

2-2 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.

(2) MODE (7EH) : Sets recording/playback mode directly.

Eg: To set to “L24H”.

TXD RXD

CLEAR (56H) : Clears the whole command. Cancels the current status and stops the VCR. Also

Eg : After setting the recording/playback mode to “L24H”, 32H is mistakenly transmitted . Cancel 32H with

“41H” and input “33H” instead.
