% [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.

& [CLOCK RESET IN] clock reset input terminal Connect to a master clock or another SR-9080’s [CLOCK RESET OUT] terminal. When the clock reset signal is input, the time is automatically synchronized with the master clock or another SR-9080’s clock.

( [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.

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 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

1	[AC IN] connector
	Connect to an AC 120 V : U model, AC220 -240 V : E
	model, 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 (except in the
	L12H/L18H/L24H mode : U model, L12H/L24H mode : E
	model).
6	[VIDEO IN] video input connector (BNC)
	Receives composite video signals from a connected
	camera or other video source.
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 Signal 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.

9	[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.
0	[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.
$	[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.

•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-9080’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.

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. 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.

) [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.
