Manual.
This device has been designed as a peripheral module for use in commercial
vehicles and mobile machines and is intended for connection to an already
existing controller. The JXM-MUX is a video splitter merging up to 4 video
signals into one video signal.
This device meets the requirements of the European Automotive EMC
Directive for electric/electronic subassemblies.
It may only be operated within the limits set forth in the technical
specifications. The operating voltage of the JXM-MUX is classified as SELV
(Safety Extra Low Voltage). Therefore, it is not subject to the EU Low Voltage
Directive.
The device must not be used in technical systems which to a high degree
have to be fail-safe.
The JXM-MUX is no safety-related part as per Machinery Directive
2006/42/EC. This device is not qualified for safety-relevant applications and

JXM-MUX Electrical installation
Product description
The JXM-MUX is a video splitter merging up to 4 video signals. Up to 4
cameras can be connected to it. The signals from these cameras are routed to
the monitor. Optionally one to four video signals can be displayed on the
monitor. Supported video standards are PAL or NTSC. Each video signal from
the cameras can be mirrored, for example when a camera is used as rear
view camera.
The video splitter is controlled by a CAN interface with implemented
CANopen® protocol.
The product features are listed below:
Video system: NTSC, PAL (5 channels)
4 camera ports (5-pin MiniDIN jacks)

1 video input (RCA/cinch)
1 audio input (RCA/cinch) (not supported)
1 video output (RCA/cinch)
1 audio output (RCA/cinch) (not supported)
Controlled by a CAN interface with implemented CANopen® protocol.
