[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.
(
[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.
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.
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.
