^[TAPE END OUT] tape end signal output terminal Outputs a signal when the tape ends during recording. If the menu switch <CNT TAPE END> on the <SRI/EXT MODE> screen is set, signals are output when the specified tape reel counter value is exceeded.

Outputs a +12 V signal during recording. When the tape ends or the specified counter value is passed, a 0 V (GND level) signal is output.

When the tape ends during auto repeat recording or auto rewind recording, 0 V signal is output for about 2 seconds.

Connect an external alarm or buzzer via an external interface.

To cancel the output, press the [EJECT] button, [PLAY] button, [FF] button or [REW] button.

&[COM] common ground terminal

Connect to the signal ground terminal of a connected unit.

*[WARNING OUT] warning signal output terminal Outputs warning signals (+12 V) when a tape running or mechanism problem occurs.

q[SERIES REC IN] series recording/VCR activation signal input terminal

Receives series recording signal or VCR activation signal from an external control device.

Select the input signal with the menu switches in the <SRI/EXT MODE> menu.

5 Series recording input

A series recording signal is input when [SRI/EXT REC] is set to “SERIES”.

Connect to another VCR’s series recording signal output terminal.

When the tape in the preceding VCR ends, a signal is delivered to this terminal and recording starts automatically.

When the menu switch <CNT TAPE END> on the <SRI/EXT MODE> screen is set, the signals are delivered when the specified tape reel counter value is reached. Recording starts automatically.

5 VCR activation signal input

When [SRI/EXT REC] is set to “EXT”, recording is

started and stopped with an external signal.

• Connect to an external control device.

1[AC IN] connector

Connect to an AC 120 V, 50/60 Hz power outlet using the provided AC power cable.

2[REMOTE] remote connector (RCA) Connect the optional RM-G30U remote control.

3[MIC IN] mic input connector

Connect a microphone with 3.6-mm dia. plug. When signals are input from both the microphone connector and the audio input connector, audio signals are mixed and recorded.

4[AUDIO IN] audio input connector (RCA)

Receives audio signals from a connected audio source.

5[AUDIO OUT] audio output connector (RCA) Outputs audio signals. No signal is output in the Timelapse Recording/Playback mode.

6[VIDEO IN] video input connector (BNC) Receives composite video signals from a connected camera or other video source.

For composite video signal input, set the <INPUT> menu switch in <VIDEO MODE> to LINE.

7[VIDEO OUT] video output connector (BNC) Outputs composite video signals. Even when the power is not supplied to this unit, input signals (composite video signals) from a camera can be output through this connector (Operating mode-Off Video Throughout function).

8[Y/C IN] connector (4 pin) Inputs separate Y/C signals.

For separate Y/C signal input, set the <INPUT> menu switch in <VIDEO MODE> to Y/C.

9[Y/C OUT] connector (4 pin) Outputs separate Y/C signals.

0Signal ground terminal

This ground terminal is not provided for safety purposes. It is used to ground signals. Connect this terminal to ground the signal between VCRs.

![CAM SW OUT] camera switching signal output terminal

When a sequential switcher is connected, this terminal outputs camera switching timing control signals. For details on these signals, refer to page 65.

@[COM] common ground terminal

Connect to the signal ground terminal of a connected unit.

#[ALARM IN] alarm signal input terminal Receives signals to start alarm or sensor recording.

$[ALARM RESET] alarm signal reset input terminal Receives signals to cancel alarm recording.

*Alarm input data is not reset.

%[ALARM REC OUT] alarm recording mode signal output terminal

Outputs +12 V signals during alarm recording.

([CLOCK RESET IN] clock reset input terminal Connect to a master clock or another SR-9090U’s [CLOCK RESET OUT] terminal. When the clock reset signal is input, the time is automatically synchronized with the master clock or another SR-9090U’s clock. However, the time difference between VCRs should be within ±30 seconds.

When the clock reset signal is input, the clock in this unit is reset as shown below.

When the seconds value is 29 or less, the minutes value is the same but the seconds value is reset to 0. (eg. 12:34:29 —> 12:34:00)

When the seconds value is 30 or more, the second value is reset to 00 and the minutes value is increased by one. (e.g. 12:34:30 —> 12:35:00)

)[CLOCK RESET OUT] clock reset output terminal Outputs the clock reset signal.

The clock reset signal is output in the following cases.

When the internal clock is at 0:00 or 12:00

When this unit is connected to another SR-9090U’s [CLOCK RESET IN] terminal, the other VCR’s clock can be set to the clock in this unit. However, the time difference should be within ±30 seconds.

If a VCR activation signal (ground input) is input to

this terminal, the VCR starts recording

automatically and continues recording for as long

as the VCR activation signal is input.

w[SERIES REC OUT] series recording signal output terminal

Outputs series recording signals.

A series recording signal is output when [SRI/EXT REC] is set to “SERIES”.

Connect to another VCR’s series recording signal input terminal.

Outputs a signal when the tape being recorded in this unit ends.

When the menu switch <CNT TAPE END> on the <SRI/EXT MODE> screen is set, the signals are output when the specified tape reel counter value is reached.
