Operating Precautions : Please read this manual carefully to avoid operation errors.
5.1. Switching on the Power
• Ensure that all connections, especially those of the power cables, are
secure.
• Switch ON the power by pressing the front panel Power switch, and
check to confirm that the power lamp lights. When the power is first
switched on, the video signal for automatic sequential switching is
output to the Monitor 2 output terminal by default.
• When finished with use, switch off the power and check to ensure that
the power lamp is extinguished.
Note
To prevent equipment failures and malfunction, do not remove or insert
the power cable when the power is on.
5.2. Camera Image Selection (Monitor 2 Output Terminal)
• Press the Sequence key and confirm that its indicator lamp lights. The
Quad Adapter will then be placed in automatic sequential switching
mode.
• Press the desired Channel Selector key (1 – 4) to select the camera
image for output to the Monitor 2 output terminal.
Important
Check to be sure that the camera image of the selected channel is
displayed on the monitor.
• Pressing the Quad Display key converts the camera images of
channels 1 – 4 into a 4-segment split-screen signal, and the signal is
output to the Monitor 2 output terminal.
Note
The Monitor 1 output terminal is factory-preset to continuously output 4segment split-screen images. If Monitor 1 is registered as [SYNCH] (Item
5-1. on p. 20), a desired image can be selected with the Sequence,
Channel Selector, or Quad Display keys. (Monitor 1 provides the same
operation as Monitor 2.)

5.3. Using the Alarm & Remote Functions
• Select either "ALARM" or "REMOTE" in the Alarm/Remote settings shown on p. 17 (Item 4-1.).
• For Alarm operations, select either "Make" or "Break" to activate an alarm depending on the type of sensor
being connected (Item 4-2. on p. 18).
• Alarm duration can be selected from the variable interval of 1 – 60 seconds. Whether or not operation
automatically returns to the previous mode after the alarm interval elapses should also be set here.
• Connect the Alarm/Remote Signal Input terminals (p. 23).
• When the alarm is activated, the monitor display connected to the Monitor 2 output terminal is switched to
the alarm-activated camera scene accompanied by a flashing "ALARM" indication. The title of the alarmactivated camera channel also flashes on the monitor display connected to the Monitor 1 output terminal.
When an alarm is activated, the Alarm Signal output terminal is grounded via a transistor. (Use the
Alarm/Remote output terminals on 12 V DC and under 30 mA.)
• When the alarm is simultaneously activated in several camera channels, the alarm-activated channel
outputs are automatically sequenced to the monitor at one second intervals.
• The alarm can be reset by pressing the Channel Selector key, Sequence key, or Quad Display key (any key
other than the Menu key). It can also be reset by entering a reset signal from the Alarm/Remote input
terminals.
• Remotely-controlled operations perform the same function as when the front panel keys are operated.
Notes
• The alarm is disabled while the setting screen is displayed.
• The alarm signal output terminal cannot be used while the Remote input terminals are in use.
• The unit's rear panel QUAD terminal is only for remote control operation.
• All Alarm/Remote Signal Input Terminals are of edge type. Once the terminal is activated, it no longer is
activated again if not reset (i.e. in break when set for "make" detection, and in make when set for "break"
detection).
