■ Connection with the Alarm
Sensors
Connect the sensor switches to the unit's alarm port, as
shown in the example.
Notes:
• Alarm inputs that are simultaneous or with very short
intervals will be ignored.
Allow for at least 100 ms interval from one alarm input to
the next.
• Confirm the alarm sensor type (N.O. or N.C.) and con-
figure the system through SETUP MENU (OSD) or WJ-
SX150A Administrator Console.
The factory setting is N.O.
N.O.: Normally Open alarm contact
N.C.: Normally Closed alarm contact
• Alarm pins assigned as the time adjusting (TIME) termi-
nals cannot be used as alarm input terminals.
• The specification of Recover Input: 5 V DC / 0 V (low-
active)
Recover Input, which resets alarm signals, is Pin No. 13
of the ALARM port. To reset alarm signals, contact GND
and Recover Input.
When you connect Digital Disk Recorder WJ-HD100
Series to the matrix switcher, set the recorder's alarm
polarity to Open-collector low by setting the MODE
switch #6 to off.

■ Connection with the System
Controllers
Connect the system controller to the DATA 1 to 4 port at the
unit's rear panel with the modular cable.
Notes:
• Up to four system controllers are connectable.
• Connect them in home run.
• In the factory default setting, the DATA 4 port is a
PS·Data terminal. To connect a terminal-mode system
controller to this port, you need to change the data port
setting through SETUP MENU or WJ-SX150A
Administrator Console. (Refer to pp. 74 or 96.)
