1 Video In Connect coaxial cables to the MMX from the video sources (NTSC or PAL). Cameras can
be connected to the MMX directly or through loop out or main out ports of DVRs.
2 Loop Connect coaxial cables to connect the video source of the MMX to another device.
3 Alarm In Connect alarm-in devices. Connect the ground side of the alarm inputs to the GND
connector. Mechanical or electrical switches can be wired to the AI (Alarm-In) and GND
(Ground) connectors. The voltage range of the alarm input is from 0V to 5V. The threshold
voltage of electrical switches for NC (Normally Close) is above 2.4V and for NO (Normally
Open) is below 0.3V, and should be stable at least 0.5 seconds to be detected.
4 MMX ID Switch Configure the MMX ID. Every MMX should have its own unique ID.
Refer to MMX ID Switch for details on MMX ID switch setting.
5 Alarm Output/
Alarm Reset In
Connect an alarm-out device to the NC (Normally Closed) and C (Common) connectors
or the NO (Normally Open) and C (Common) connectors. NC/NO is a relay output which
sinks 2A at 125VAC and 1A at 30VDC. An external signal to the Alarm Reset In can be
used to reset the Alarm Out signal. Mechanical or electrical switches can be wired to the
ARI (Alarm Reset In) and GND (Ground) connectors. The threshold voltage is below 0.3V
and should be stable at least 0.5 seconds to be detected.
