1 INTRODUCTION

1-1 Major Features

5 Extended timelapse recording for up to 960 hours

Recording times are selectable from 2 hours (SP mode),
6 hours (EP mode) and 24/48/72/120/168/240/480/960
(Timelapse mode) (when T-120 tape is used).

5 High-resolution recording
Delivers horizontal resolution of more than 400 lines

even in color mode.
*When a tape recorded on this unit is played back on

another VCR, noise may appear on playback picture.

5 High-density recording (HDR) function
Using the EP head, the tape is advanced at a fine pitch

for timelapse recording. In this way, about three times
more information is recorded in the same period than in
conventional timelapse modes. While this results in
some degradation of picture quality, the increased
coverage allows you to analyze the development of a
situation in greater detail. The actual recording duration
on the tape is the same as that of an ordinary timelapse
recording (select with menu switch <HDR>).

5 Alarm recording function

When an alarm signal is input in the Record mode, the
2/6-hour mode is automatically engaged. Alarm
recording time can be selected from 5, 10, 15, 30, 60,
120, or 180 sec., to tape end, or set manually.
An index code is automatically recorded at the start
point of the alarm recording for use as an alarm cue
signal. Alarm recording points can be accessed quickly
with the alarm search function.

5 Sensor recording

Whenever an alarm signal is input in the Stop mode

(Stop, Timer Recording Standby or Operating Off
mode), the Record mode is automatically engaged.

5 Time/date generator

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

5 Timer-recording function

Up to 8 programs can be set for daily, weekly, or
weekday timer-recording. You can also set timer
recording for up to 16 days a year by specifying the date
(holidays, for example).

5 Tape position search function
You can automatically search the start of an alarm

recording or search for a recording made at a specified
date and time.

5 Recording check function

Recording conditions (quality) can be checked at any
time during recording by pressing the recording check
button.

5 Operation lock system

The secret operation lock system prevents an accidental
or deliberate interference with VCR operation.

5 Camera switching signal output terminal
5 Warning function

cassette loading, cassette unloading, or the rotating
system operation mode.

5 Operating mode-off video throughout function

Even when the operating mode is off, the camera’s EE
input can be output from the VCR.

5 Series recording function

Two or more SR-9090U can be connected for extended,
long-term series recording. As the tape in each VCR
reaches the end, the next unit in the series will
automatically start recording.

5 Automatic re-start of recording after a power failure
5 Time adjust function

With the IN/OUT terminal for time adjustment, the time
difference can be set to “0” with multiple SR-9090Us
connected. (adjustment time: 00:00/12:00)

5 Digital hour meter display
5 Repeat playback/recording
5 Alarm recording, tape end and warning electronic

buzzer

5 Recording control with external activation signal
5 Counter end function
5 External timer connection
5 Summer time compensation function
5 Wired remote control (optional)

Used when an optional SA-K97U RS-232C interface
board is installed.

5 RS-232C control

The SR-9090U can be controlled via a personal
computer. Operation status can be monitored on the
computer.

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 20) 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 in the shaded
area indicate that maintenance should be performed.

1-3 Precautions

Handling and storage place

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 To avoid overheating the unit, do not block

ventilation slots or stack the units. If the internal
temperature rises too high, the tape may be
damaged.

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 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 Do not leave the unit in the Still or Record Pause mode

for a long time as this may damage the tape.

After about 3 minutes, this unit automatically enters the
Stop mode.

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 When condensation is expected to occur

Turn the power of the VCR on before use.

5 If condensation has occurred

The VCR automatically ejects the cassette and the error
indication “E-08” blinks on the display. Operation is
disabled until the “E-08” indication on the display goes out.

2 CONTROLS AND CONNECTORS

1-3 Precautions

Video cassette

Erasure prevention tab

Timelapse recording is performed over very
long periods of time which means that a
durable tape is required.
When using VHS tapes, do not use tapes with
recording times of more than 120 minutes
(T-160/T-180 etc.).
For best results, use a T-120 tape.

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/playback
function on a daily basis.

Inspection procedure

1

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

2

Check the quality of the image shown on the monitor.

• 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.

To obtain the best picture quality, use an HG (high
grade) tape (a JVC cassette is recommended).
Degradation of picture quality may result with some
types of tape. Make a test recording before
performing any important recording to check the
picture quality.

3

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

4

Rewind the tape recorded the previous day for several
seconds.

5

Press the play button for playback.

6

Check that the playback picture is normal.

7

Check that the recorded date and time are correct.

5 This unit includes a Recording Check function (using the

[REC CHECK] button). Use these features to quickly
check recording quality on a daily basis.

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

High-Density Recording

HDR is performed with the EP heads. When HDR is set to “OFF”, recording is performed with the SP heads.
In the HDR mode, the interval between frames (fields) is reduced by about a third, allowing three 3 times as many frames
to be recorded as in the ordinary timelapse mode. This does not affect the actual recording time of the tape (the recording
time is the same as it would be if recorded in the normal (SP) Timelapse mode).
The quality of the picture recorded in the HDR mode is inferior to that in ordinary timelapse recording (equivalent to the EP
mode).

To check the recording

● To check recording in the Timelapse mode, the

recording duration must be equivalent to at least 8
seconds at 2H(SP) or 6H(EP) speed. Recording
check cannot be performed correctly if the recording
duration is too short. (Example : In the 960-hour
normal timelapse mode, the recording duration shoud
be 64 minutes or more.)

● During recording check, the audio signal is not output.

5 Press the [REC CHECK] button during recording.

→ The tape is automatically played back in reverse for

about 5 seconds, then the Play mode is engaged to
allow you to check recording. After the sequence
has played back, the recording mode is automatically
re-engaged at the point where the recording was
interrupted.

• During playback in the Recording Check mode, check
the picture to ensure that the recording is satisfactory.

If the signals are not recorded properly, the built-in

head cleaner cleans the heads and recording
continues. In this case, the error code “E-09” is shown
on the display for about 10 seconds.

6-6 Series Recording

The series recording function facilitates recording over much longer periods using several connected SR-9090Us.
As soon as the tape ends in one VCR, the next VCR in the series starts recording. Using the counter end output function
enables smoother switchovers during series recording, mostly eliminating interruptions between tapes.

Connections

5 Connect the first VCR’s [SERIES REC OUT] terminal to the

second VCR’s [SERIES REC IN] terminal. Connect the
second VCR’s [SERIES REC OUT] terminal to the third
VCR’s [SERIES REC IN] terminal. Repeat for all connected
VCRs. Connect the VCR’s [COM] terminals as well.

5 Connect a video camera and/or other source equipment to the

first VCR’s video and audio input connectors.
Connect the first VCR’s video and audio output connectors to
the second VCR’s video and audio input connectors. Connect
the second VCR’s video and audio output connectors to the
third VCR’s video and audio input connectors.
Repeat for all connected VCRs.
Connect the last VCR’s video and audio output connectors to
the monitor’s video and audio input connectors.

terminal at the specified tape reel counter value,
signaling the next VCR to start recording.
The first VCR continues recording until the tape ends.

Non-stop continuous series recording

The series recording function allows you to record indefinitely using two VCRs. Recording alternates between each VCR.
To use this function, connect and set the VCRs as follows.

5 Connection

• Connect the [SERIES REC OUT] terminal of the
first VCR to the [SERIES REC IN] terminal of the
second VCR, and the [SERIES REC OUT]
terminal of the second VCR to the [SERIES REC
IN] terminal of the first VCR. The [COM]

Operation

1

Set the <SRI/EXT REC> menu switch in <SRI/EXT
MODE> to “EXT” to use the external recording function.

• Use the <EXT REC END> menu switch to select the
mode engaged when externally activated recording
ends.
When set to “STOP”, the VCR enters the Stop mode.
When set to “OPE OFF”, the operating mode is turned
off.

2

Press the [MENU] button to set the on-screen display to
the time/date display.

3

Load a cassette with a safety tab in place and engage the
Stop mode or turn the operating mode off.

• When a VCR activation signal (ground input) is input to
the rear panel’s [SERIES REC IN] terminal, recording
starts automatically and continues for as long as the
activation signal is input.
When the activation signal stops, the Stop mode is
engaged or the operating mode is turned off (according
to menu switch setting).

• When the activation signal is input again, recording starts.

* If the external recording function is activated a hundred

times a day or more, a malfunction may occur because
the guaranteed range is exceeded.
If you want to use this unit more than a hundred times a
day, set the recording speed mode to 2H/6H and
perform regular maintenance, replacing parts as
necessary.

External control
equipment

Connect the [SERIES REC IN] terminal and [COM] terminal
on the SR-9090U’s rear panel to the external control equipment.

Alarm search/date and time search

• Alarm recording or sensor recording should continue for
at least 5 seconds.

• When recording is performed in the long-time timelapse
mode, date/time search will not function correctly if the
recording duration is too short.
To ensure that the date/time search operates correctly,
the recording duration must be equivalent to at least
5 seconds at Standard (2H) or EP (6H) speed.

(Example) With a 960-hour normal timelapse recording,
a recording time of 40 minutes or more is necessary.

sound, set the menu switch <TAPE END> to “OFF”,
perform another operation (such as pressing the [REW]
button) or press the [OPERATE] button.

5 During repeat recording and auto rewind, the buzzer

sounds for about 2 seconds.

Notes on playback

Tapes recorded on this VCR cannot be played back on
standard VHS VCRs. Use this VCR, an S-VHS VCR or a
VCR with SQPB function to play back tapes recorded on
this unit. Also be aware that not all S-VHS VCRs will be
able to play back tapes recorded on this unit, because
some use different S-VHS/VHS detection methods.
Try to avoid operations such as shuttle search or field
advance playback as much as possible. These put a
comparatively high stress load on the tape and can lead
to picture degradation over time.
During shuttle search or field advance playback, noise may
appear. This is normal with this unit and is not a malfunction.

7-4 Alarm Search/Date and Time Search

There are three different ways you can search a tape position.
When the [SEARCH] button is pressed, the Search mode is engaged. Each time the [SEARCH] button is pressed, the Search
mode changes.

• (Once) alarm search: To search the start of an alarm recording.
(Twice) alarm scan: To play back around the start of each alarm recording for several seconds.
(Three times) date/time search: To search for a recording made at a specified date and time.
Press the [SEARCH] button four times to cancel the Search mode.

Note on date/time search

Recording duration is especially important with timelapse recordings. If the duration is too short, date/time search will not
function correctly. The recording duration must be equivalent to at least 5 seconds at Standard (2H) or EP (6H) speed.

(Example) In the 960-hour normal timelapse mode, the recording time should be 40 minutes or more.

Error indications are shown on the display whenever
condensation occurs or there are problems with cassette
loading, unloading or mechanism operation.

5 When a problem occurs, the error indication “E-**” lights

(when the <WARNING> menu switch in <F. DISP> is
set to “ON”).

5 When any one of error indications (E01 - E08) is shown,

a 12-V warning signal is output from the rear panel’s
WARNING OUT connector.

5 When the <WARNING> menu switch in <BUZZER> is set to

“ON”, the buzzer sounds if a problem occurs (E-01 - E-08
and E-11 (during recording)).

When an error indication appears or the buzzer sounds,
turn the operating mode on again to clear the error
indication and buzzer sound (E-01-E07).
When the error indication “E-**” is shown, turning the

9-3 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). When the operating mode is turned on,
the VCR is in the “ON” status.
The VCR can now receive any command described in this section. To cancel the communications mode, transmit the command “JVC
TABLE 1 OFF” (F7H).

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.
(6) REW (ACH) : REW/Reverse search in the Play mode.
(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) : Advances the tape by one field when the VCR is in the Still mode and engages the Still mode.

(12) R-FIELD STEP (AEH) : Reverses the tape by one field when the VCR is in the Still mode and engages the Still mode.

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

Before transmitting either of the following commands ((14) or (15)), first transmit REC/DUB REQUEST (FAH), and confirm that “ACK” (0AH) is
returned by the VCR.

(14) REC (CAH) : Starts recording. The VCR returns “ACK” (0AH).

(15) REC PAUSE (CBH) : Engages Record-Pause mode. The VCR returns “ACK” (0AH).

After transmitting commands VISS FWD (16) or VISS REV (17), 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. * Transmit the commands (16) and (17) in the Stop mode.

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

(17) 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

B0H 33H 40H

RXD

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

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

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

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

If the cassette tape’s safety tab [REC TAB] has been removed, NAC (0BH) is returned.

• When REC PAUSE (FAH + CBH) is sent in the Record mode, the Record-Pause mode is
engaged.

• When STOP (3FH) is sent in the Record mode, the Stop mode is engaged.

If the cassette tape’s safety tab has been removed, NAC (0BH) is returned.

• To re-start recording, transmit REC (FAH+CAH).

• To cancel Record-Pause, transmit STOP (3FH). The VCR will enter 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 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

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

In this status, no command can be accepted and only STATUS SENSE will be returned.
To restore normal operation, transmit CLEAR ERROR (41H) or CLEAR (56H) to the VCR.

CLEAR ERROR (41H) : Used to cancel previously-transmitted 1-byte numeric data when inputting

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