GENERAL DESCRIPTION
The model GMJ1939 is a J1939 communication module designed
for use with the Graphite products. The module provides the
Graphite host device a J1939 communications port. It is built with
digital isolation to protect the Graphite host device from the J1939
bus and vice versa. It provides the ability to communicate to any
J1939 device. The GMJ1939 module has a termination resistor
built-in, and is selectable through a switch. The connector is
pluggable for easy removal of the GMJ1939 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 Graphite devices. The Graphite 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 Graphite device, see
specific model for details. Remove power from the host device
before installing or replacing any modules.
CONFIGURATION
The Graphite is configured with Windows®compatible Crimson
3 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 Red Lion Controls 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. The following EMI
suppression devices (or equivalent) are recommended:
Fair-Rite part number 0443167251 (Red Lion #FCOR0000)
Line Filters for input power cables:
Schaffner # FN2010-1/07 (Red Lion #LFIL0000)
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 Red Lion 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

CONFIGURATION
Programming is done via Crimson 3 software, a Windows®
compatible configuration interface. Please see the Crimson
manual for more information.
J1939 PORT PROTOCOLS
The GMJ1939 module has one J1939 port. This port may be
configured for various J1939 protocols.
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 Graphite host device.
CAN-
Position 2 of the pluggable connector provides the CAN- bus line
(active low). This terminal is isolated from the Graphite host device.

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.

guidelines, Safety and CE issues as they relate to Red Lion
products.

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 Graphite host device
enclosure.
CAN+
Position 4 of the pluggable connector provides the CAN+ bus line
(active high). This terminal is isolated from the Graphite 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 GMJ1939 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 GMJ1939
module or Graphite 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 Crimson.
Green Module performing normally.
Error States
Flashing Green Module has lost communication with the Host.
RUN/ERROR LED
Green GMJ1939 module established communication with other
J1939 devices (RUN) and is communicating normally.
Red GMJ1939 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, Crimson compares its own library of
firmware files with those stored in the module. If they do not
match, Crimson will download the necessary firmware.
