GENERALDESCRIPTION
The MV-J1939 is a J1939 communication module designed for use
with CAN enabled devices using J1939 protocol. The module provides
the M-VIEW a J1939 communications port. It is built with digital isolation
to protect the M-VIEW from the J1939 bus and vice versa. It provides the
ability to communicate to any J1939 device. The MV-J1939 module has
a termination resistor built-in, and is selectable through a switch. The
connector is pluggable for easy removal of the MV-J1939 module from
the J1939 bus, without disturbing communications with other devices on
the bus.
The modules connect and communicate via proprietary USB
connection to the various M-VIEW devices. The M-VIEW devices,
equipped with serial ports as well as Ethernet port(s), allows the system
to share data with PCs, PLCs and SCADA systems. The maximum
number of modules varies for each M-VIEW device, see specific model
for details. Remove power from the host device before installing or
replacing any modules.

CONFIGURATION
The M-VIEW is configured with Windows® compatible M-VIEW
DESIGNER 3.1 software. The software is an easy to use, graphical
interface which provides a means of configuration and commissioning of
new systems, as well as routine module re-calibration.
SAFETYSUMMARY
All safety related regulations, local codes and instructions that appear
in this literature or on equipment must be observed to ensure personal
safety and to prevent damage to either the instrument or equipment
connected to it. If equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be
impaired.
Do not use this unit to directly command motors, valves, or other
actuators not equipped with safeguards. To do so can be potentially
harmful to persons or equipment in the event of a fault to the unit.

EMCINSTALLATIONGUIDELINES
Although FW Murphy products are designed with a high degree of
immunity to Electromagnetic Interference (EMI), proper installation and
wiring methods must be followed to ensure compatibility in each
application. The type of the electrical noise, source or coupling method
into a unit may be different for various installations. Cable length, routing,
and shield termination are very important and can mean the difference
between a successful or troublesome installation. Listed are some EMI
guidelines for a successful installation in an industrial environment.
1. A unit should be mounted in a metal enclosure, which is properly
connected to protective earth.
2. Use shielded cables for all Signal and Control inputs. The shield
connection should be made as short as possible. The connection point
for the shield depends somewhat upon the application. Listed below
are the recommended methods of connecting the shield, in order of
their effectiveness.
a. Connect the shield to earth ground (protective earth) at one end
where the unit is mounted.
b. Connect the shield to earth ground at both ends of the cable, usually
when the noise source frequency is over 1 MHz.
3. Never run Signal or Control cables in the same conduit or raceway with
AC power lines, conductors, feeding motors, solenoids, SCR controls,
and heaters, etc. The cables should be run through metal conduit that
is properly grounded. This is especially useful in applications where
cable runs are long and portable two-way radios are used in close
proximity or if the installation is near a commercial radio transmitter.
Also, Signal or Control cables within an enclosure should be routed as
far away as possible from contactors, control relays, transformers, and
other noisy components.
4. Long cable runs are more susceptible to EMI pickup than short cable runs.
5. In extremely high EMI environments, the use of external EMI
suppression devices such as Ferrite Suppression Cores for signal and
control cables is effective.
Contact FW Murphy Technical Support for recommendation for your
application.
6. To protect relay contacts that control inductive loads and to minimize
radiated and conducted noise (EMI), some type of contact protection
network is normally installed across the load, the contacts or both. The
most effective location is across the load.
a. Using a snubber, which is a resistor-capacitor (RC) network or metal
oxide varistor (MOV) across an AC inductive load is very effective at
reducing EMI and increasing relay contact life.
b. If a DC inductive load (such as a DC relay coil) is controlled by a
transistor switch, care must be taken not to exceed the breakdown
voltage of the transistor when the load is switched. One of the most
effective ways is to place a diode across the inductive load. Most FW
Murphy products with solid state outputs have internal zener diode
protection. However external diode protection at the load is always a
good design practice to limit EMI. Although the use of a snubber or
varistor could be used.
7. Care should be taken when connecting input and output devices to the
instrument. When a separate input and output common is provided,
they should not be mixed. Therefore a sensor common should NOT be
connected to an output common. This would cause EMI on the
sensitive input common, which could affect the instrument’s operation.

TERMINATIONRESISTOR
An onboard termination resistor is selectable through a switch. The
termination resistor is rated for 124Ω at 1W. If a different termination
resistance is desired, slide the switch for no termination resistor. At this
point you will be required to connect your own termination resistor
between positions 2 and 4 of the five position connector.
