JXM-HMI User Manual 7 / 22
3 Product description
The JXM-HMI is a universal human-machine interface with three rugged push en-
coders. It is therefore ideally suited for a wide range of dosing and control appli-
cations in self-propelled machines. Thanks to its compact design, the JXM-HMI
can be flexibly mounted individually or in combination with a JetViewMobile 104,
for example, in the driver's cabin. Integrated LEDs ensure that the push encoders
are always perfectly visible.
The CANopen® communication interface lets you connect the module to common
CAN networks of self-propelled machines.
3.1 Features
■1 CAN port with terminating resistor
■Communication via CANopen® protocol
■Adjustable key illumination
■3 push encoders

4 Mechanical installation
Mount the JXM-HMI only in a suitable place in the vehicle interior.
NOTICE Damages to material or functional impairment
Welding on the chassis may cause damages to material of the device, or impair
its functions.
● Before you start welding, disconnect all connections between the device and
the electric system of the vehicle.
● Protect the device from flying sparks and welding beads (splatter).
● Do not touch the device with the welding electrode or earth clamp.
4.1 Mounting in combination with a JVM-104
The JXM-HMI is particularly well suited for use in conjunction with the JVM-104
HMI. A special mounting plate is available for this purpose which enables both
devices to be mounted together.
Mounting Acces-
sories
Use the following accessories for installation:

➅RAM Mount ball
➆2 x self-locking nuts
1. Screw the desired RAM Mount attachments onto the mounting plate.
2. Hold the JXM-HMI and the JVM-104 against the mounting plate from behind.
The connectors must be accessible through the openings in the mounting
plate.
3. Screw the mounting plate onto the JVM-104 and the JXM-HMI.
Installing the strain
relief
Install strain reliefs for the connecting cables.
■Ensure that there is sufficient clearance between the strain reliefs and the con-
nectors.
■Connectors must not be obstructed, so that they can be removed in the event
of service.
4.1.1 Requirements for the installation location
■The installation surface must be level.
■The installation surface should be no more than 5 mm thick.
■The installation location must allow air to circulate.
■The installation compartment must allow adequate air circulation.
■The installation location must be of sufficient size.
■The device must be easily accessible to allow for service work.
Space required for
installation and ser-
vice
It must be possible to disconnect the connectors at any time.
Avoiding unsuit-
able installation lo-
cations
The following installation locations are unsuitable for installation:
Unsuitable installation location Reason
Outdoor installation The device must not be exposed to rain
or a jet of water. Do not use a steam jet
or other such devices to clean the de-
vice.
This location is not ventilated. The JVM-104 could overheat as heat
builds up.
Installation location close to heat-sensi-
tive materials
The materials could become warped or
misshapen as a result of heat produced
by the device.
Installation surfaces are uneven. The installation surface could become
misshapen when fitting the device. Fas-
tening is unstable and precarious.
