GENERAL DESCRIPTION

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.

EMC INSTALLATION GUIDELINES
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 varactor (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 varactor 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.

HARDWARE INSTALLATION
The physical order of all installed modules must match the modules order in M-VIEW DESIGNER 3.1. Torque screws to 6.0 pound-force inch [96 ounce-force inch] (0.68 Nm).
WARNING: Disconnect all power to the unit before installing or removing modules.

COMMUNICATING WITH THE MV‐J1939 MODULE

CONFIGURATION
Programming is done via M-VIEW™ DESIGNER 3.1 software, a Windows ® compatible configuration interface. Please see the M-VIEW DESIGNER 3.1 User Manual for more information.
J1939 PORT PROTOCOLS
The MV-J1939 module has one J1939 port. WARNING – EXPLOSION HAZARD – DO NOT CONNECT OR DISCONNECT CABLES WHILE POWER IS APPLIED UNLESS AREA IS KNOWN TO BE NON-HAZARDOUS.

TERMINATION RESISTOR

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.

CAN GND
Position 1 of the pluggable connector provides a CAN ground connection. This terminal is isolated from the M-VIEW host device.
CAN‐
Position 2 of the pluggable connector provides the CAN- bus line (active low). This terminal is isolated from the M-VIEW host device.
SHLD (CAN SHIELD)
Position 3 of the pluggable connector is provided for shield connections. This position is available to tie shield wires to earth ground. The SHLD position is connected through a series RC network to CHASSIS as noted in specification J1939-11. The SHLD connection is internally tied to the M-VIEW host device enclosure
CAN+
Position 4 of the pluggable connector provides the CAN+ bus line (active high). This terminal is isolated from the M-VIEW host device.
V+ (OPTIONAL 24 VDC)
Position 5 of the pluggable connector is provided for optional 24 VDC connections. This position is available only to tie 24 VDC wires together. The MV-J1939 module neither provides 24 VDC power nor uses 24 VDC power through this  connection. The V+ position is not connected to any circuitry internal to the MV-J1939 module or M-VIEW Host device.
LEDs
STS – STATUS LED
The Status LED is a green/red LED that provides information regarding the state of the module. This includes indication of the various stages of the start-up routine (power-up), as well as any errors that may occur. Startup Routine

Flashing Red| Module is currently running the boot loader and/or
being flash upgraded by M-VIEW DESIGNER 3.1.
---|---
Green| Module performing normally.

Error States

RUN/ERROR LED

Green| MV-J1939 module established communication with other J1939 devices (RUN) and is communicating normally.
---|---
Red| MV-J1939 module failed to establish communications with other J1939 devices (ERROR).

FIRMWARE UPGRADE
The module’s firmware is stored in flash memory so that software/ hardware conflicts are avoided, and so features can be added in the future.
During a download, M-VIEW DESIGNER 3.1 compares its own library of firmware files with those stored in the module. If they do not match, MVIEW DESIGNER 3.1 will download the necessary firmware.
M‐VIEW TROUBLESHOOTING
If for any reason you have trouble operating, connecting, or simply have questions concerning your new M-VIEW unit, contact FW Murphy’s technical support.
