Exterior Description
The Trimble DCM300 devices are rugged telematics and data communications
appliances. The device enclosure is made of heavy duty aluminum. The exterior
has six faces-a bottom, top, and four sides. The front face of the device contains
the electrical harness connector and antenna ports. The bottom of the device and
includes the four mounting through-holes. Figure 1 below provides labels for most
of these items.
Figure 1 - DCM300 Exterior
Electrical Connector
The main harness connector on the front face is a 34 pin weatherproof electrical
connector with a mechanical locking system. The connector pinout and basic
harness configuration are described in Appendix A of this document.
Each machine installation may utilize a specialized wiring harness depending on
the telematics features available on that particular machine. Trimble recommends
that only harnesses provided by Trimble or by your machine’s original equipment
manufacturer be used with the DCM300 device.
Important – If adding additional conductors to a factory harness, the conductors must be at least 18AWG. Larger
conductors are acceptable.
Antenna Connectors
The DCM300 devices have connectors for three external antenna elements. Using
standard components, each of these connectors attaches to a single antenna unit. The
GPS antenna connector is an SMA female unit. The M2M GSM cellular modem
connector is a TNC female unit. The WiFi antenna connector is a reverse polarity TNC
female unit. Figure 2 below shows the locations of these connectors.
Figure 2 -Front Face
Mounting Hardware
DCM300 devices have four through-hole mounting points. These are located at the
four outside corners of the bottom face. It is important to use the proper mounting
hardware to install these devices. The device is intended to be rigidly mounted to
the asset to be monitored. No shock mounts are required.

General Installation Requirements
The general requirements for a system installation are to install the main unit, antennas,
and wiring harness. From a high level, this is a very simple process. There are details to
consider in each of these installation subprocedures. This section describes each of these
items as a standalone topic in order to provide adequate detail. While reading this section,
imagine the machine in which you will be installing and consider how these procedures will
have to be altered for that machine. If you do not have a specific machine on which to
install, use the vibratory compactor shown in Figure 4 as an example. It is important to
keep all three of these installation items in mind during planning. The location of the
antennas or the avaiable route for the wiring harness could affect the location of the main
unit.
Figure 4 - Sample Installation Asset
Main Unit Location Determination
Determining the mounting location of the DCM300 main device is an important part of the
overall installation process. The device is intended to be installed in any location where
an electronic control module (ECM) might be installed. ECMs are commonly installed in
the cab or out of the cab in a service compartment. There are several factors to keep in
mind when determining this location. These include:
• Moisture - The device has a waterproof housing. However, you should take reasonable
care to ensure that the unit is not continually exposed to water.
• Dirt/Debris – The device can withstand intrusions by solids but do not install it in a
location where it will become caked in mud. This could lead to overheating.
• Heat – The device should not be installed in an overly hot environment. Do not mount
the device in direct contact with a heat dissipating structure. If mounting near a radiator,
the device must be on the cool air side of the radiator.
• Sunlight – Sunlight will not damage the device but solar energy will heat the device
potentially beyond its operating range. Install in a shaded location if possible.
• Chemical exposure – Do not install the device where it will be continually sprayed by
chemicals including fuel, oil, and hyrdraulic fluid.
• Airflow – The device should be installed in a location with free airflow if possible. This
may not be a concern in extremely cold environments.
• Accessibility – The device should be installed in a location that is easily accessible for
service.
• Security – If possible, the device should be installed in a compartment that will be locked
when the asset is unattended. Alternatively, the device should be installed where it is not
easily sighted to reduce the chances of tampering.
• Shock and Vibration – The DCM300 is designed for use on construction equipment.
Attaching to the vehicle chassis or body is standard procedure and will work well. Do not
attach the device to a subcomponent that is prone to extreme shock or vibration.
Examples of undesirable attachment locations include the engine block, vibratory
implements, and suspension components.
• Mounting space – There must be a flat attachment area with minimum dimensions of
230mm x 185mm.
• Main Harness access – It must be possible to route the main harness to the location of
the DCM300 device.
• Coaxial Connector access –It must be possible to access the coaxial connector face of
the device and to attach cables to that face. Note that the connector face of the device is
one of the longer(215mm) sides of the enclosure.
• Antenna cable access – It must be possible to route the antenna cables between the
antenna locations and the DCM300 device location.
• Electrical Interference – The DCM300 device operates well in electrically noisy
environments but installation best practices include avoiding close proximity to alternators,
generators, electric motors, DC to AC converters, switching power supplies, and arc
welding equipment. If electrical interference is suspected, enclose the DCM300 device
wiring harness in a grounded shield wrap or grounded conduit.
• Nearby connection to the asset’s CANbus data bus. Limiting the length of this portion of
the wiring harness will reduce the likelihood of affecting data bus performance.
Wiring Harness Route Planning
The wiring harness must have its 34 pin connector located at the main unit location. The other
end of the conductors may go to various locations. Now that the location of the main unit is
planned, locate the chassis conductors that will have to be attached to the main harness.
Make sure that there is a route available for each conductor. Also make sure that it is possible
to mechanically secure all conductors frequently along their routes. This will help eliminate
chaffing and mechanical breakdown of the system wiring. Also plan the location of all inline
fuses. These will have to be easily accessible for future maintenance. Plan to wrap as much
of the harness and individual conductors as possible in a sheath of some sort to reduce the
chances of damage. This sheath may be as simple a split loom or as complex as rigid conduit
depending on available materials and the service duty expected on the particular machine.
Figure 5 below shows some of the major connections common in many installations.
Figure 4 - Harness Wiring Diagram
Antenna Location Determination
The antenna locations will have a significant effect on the quality of your DCM300
device performance. It is not always possible to install the antennas in a perfect
location but the installer should strive to eliminate compromises wherever possible.
The general requirements for the antenna locations and mounts are:
Signal blockages - Clear sky from the zenith to the horizon, in all directions (360 degrees).
Orientation - Antenna should be close to level with the receiving elements aimed skyward.
Interference – Avoid antenna colocation. A separation of at least 1m(3.14’) from radio
signal transmitters is necessary.
Separation – GPS/Cellular antenna and the WiFi antenna must be spaced at least 20cm from
one another to comply with radio frequency regulations.
Proximity to people – The antennas must be located at least 20cm away from the machine
operator and any other occupants.
Security – The antennas should not be easily sighted for tampering/disablement.
Permanence – The antennas should be firmly attached to the asset so that they will not come
loose due to shock, vibration, or thermal cycling.
Space/Attachment point – There must be adequate space to adhere or mechanically attach
the antennas to the asset.
Distance to the Main Unit – It must be possible to connect the antennas to the DCM300
device with the available length of antenna cable.
Electrical Isolation – If the antenna has a conductive housing, that housing must not connect
to chassis ground.
Main Unit Installation
Once the mounting location is known, the main unit installation is a straightforward
process. The mounting surface should be drilled to provide four mounting bolt holes. The
dimensions of this hole array are 215.4mm x 60mm. The coaxial connectors are on one
of the longer faces of the device which coincides with the 215.4mm mounting hole
dimension. Be sure that there is connector access on one of the sides with the 215mm
dimension. The drilled holes should be large enough to pass a ¼” bolt through them.
Once the mounting bolt holes have been prepared, gather the required attachment
hardware. This may include nuts and washers for the back side of the attachment face.
Using bolts or bolts and nuts, secure the device to the mounting surface. Torque the
attaching hardware to the proper specification.
Figure 5 - DCM300 Main Unit Mounting
Antenna Installation
Install the antennas in the locations selected using the criteria stated on the previous
page. Follow the instructions for the particular antenna kit provided. Antenna
installation will involve either bolting a mount to the asset or attaching an antenna
using industrial double-sided tape. Protect the antenna coaxial cable at any locations
where it might be subjected to abrasion or stress. Use conduit or split-loom for this.
Attach the two antenna connectors to the main unit to complete the antenna
installation process. Only hand tighten these connectors. Using tools will lead to
over-tightening and connector damage.
Each antenna must be at least 20 cm away from any other antenna.
Wifi and Cell antennas must be at least 20 cm away from vehicle operator location.
Important -
If the antenna used has a conductive housing, that housing must not connect to
chassis ground.
Main Harness Installation
The main harness provides all electrical signals to and from the DCM300 main unit. If
using a main harness specifically designed for the make and model of construction asset
on which you are installing, follow the manufacturer’s instructions to install that harness.
The connection points to the asset’s wiring will have to be located before making any
connections. There are two signals that must be supplied to the device in any application
– unswitched postive power and battery negative. Do not bypass the negative master
disconnect switch in heavy equipment. Do not use chassis ground in place of battery
negative. In order to track engine hours, the ignition sense signal wire should be
connected to a ignition-switched source or the alternator’s R-terminal. Any desired digital
inputs will need to be connected to the main harness. If CANbus communications will be
used, the proper two conductors for the vehicle bus must be located. A fuse should be
installed on all power connections. If you must extend any of the main harness
conductors for the installation, the wire used must be 18awg or larger. This means that
the awg label number will be 18 or a lower number. Appendix A contains a complete
description of the conductors in the main harness.
Before connecting any signal conductors, place the main harness 34 pin connector very
near the DCM300 device’s corresponding connector. Do not plug the harness in yet.
With the connectors in close proximity, attach the main harness to the machine using tie
wraps. This will ensure that the connectors can be mated after the harness has been
wired to the asset.
Connect the Ground signal conductor (black) to a battery negative source. Connect the
Unswitched Power conductor (red) to an uninterrupted source of positive voltage. Be sure
to place a fuse inline with this connection. These two conductors are enough to provide
basic device operation.
In order to track the asset’s run time hours, the Ignition Sense wire (white) should be
connected to the R-terminal on the engine alternator or a signal source that switches high
when the ignition key is activated.
There are three digital inputs available on DCM300 devices. Digital Input 1 is active high.
This means that the device will treat the input as active when the input signal on this line
rises to the system voltage. Digital Inputs 2 through 4 are active low. This means that
these inputs will be treated as active when the input signal is grounded.
The DCM300 also supports a single serial port and a dual CANbus ports. Trimble does
not recommend that these be connected in a basic installation. If these connections are
needed in an installation, please contact Trimble for additional details on connecting these
items.
As a final step, mate the main harness connector to the 34 pin port on the DCM300
device.
Move the asset to a location where the GPS antenna has a clear sky view and cellular
signal reception.
SIM Card Installation
In some regions, the factory SIM card in the DCM300G unit will need to be replaced with
a card for a local cellular provider. If this is the case for the unit to be installed, follow the
instructions in this section.
The SIM card installation should take place in a dry, clean environment. Before
beginning work, discharge the DCM300 enclosure to chassis ground to reduce the
chances of ESD damage. The SIM door is located at the back of the enclosure, away
from the 34 pin connector.
1) Remove the two screws securing the SIM door.
2) Remove the SIM door. Place SIM door and screws to the side.
3) This SIM carrier needs to be ejected by pushing on the unlock button to the side of the
SIM carrier.
4) Slide the SIM carrier out and turn upside down. Place SIM with the notched corner
matching the notched corner in the carrier.
5) Turn SIM carrier upside down, with SIM facing the back of the case, SIM carrier with
notch on the forward edge.
6) Carefully slide SIM carrier back into the SIM rails until it is seated in place.
7) Reinstall the door and 2 retaining screws and torque to 5 in/lbs.
8) Update the SIM door label to reflect the new SIM information.

(This page intentionally left blank)
Setup and Assistance
a. PC with serial and Ethernet ports
i. Ethernet adapter on PC must be configured as
IP Address: 192.168.1.1
Subnet Mask: 255.255.255.0
b. Hyperterminal
Set to 115,200 baud ; 8 data bits ; No parity ; 1 stop bit
1. Verifying that the unit is powered
a. Connect the operating PC to the Ethernet port on the DCM300.
b. Turn the machine’s keyswitch to On.
c. Open a browser on the PC.
d. In the browser’s address bar, type 192.168.88.3.
e. Press Enter. You should reach a web page as shown below.
The display of this webserver indicates that the DCM300 is powered and operating.
2. Verifying that the cellular modem is operating
a. Still in the DCM300 Service Tool web page, left click on the “Cell” menu item at the left
side of the screen. A screen like the one shown below will be displayed.
b. Inspect the xxxx field. This should display a value of yyy or ssss to indicate that the
modem is operating.
3. Verifying that the GPS receiver is operating
a. Still in the DCM300 Service Tool web page, left click on the “GPS” menu item at the left
side of the screen. A screen like the one shown below will be displayed.
b. If at least one satellite is detected, the GPS system is probably capable of functioning. If
the antenna currently has a clear sky view, there should be at least four satellites in view.
c. If latitude and longitude values are displayed, and the Status is OK, the GPS receiver is
working well.
4. Verifying keyswitch state sensing
a. Still in the DCM300 Service Tool web page, left click on the “Vehicle” menu item at the
left side of the screen. A screen like the one shown below will be displayed.
b. Note the Key Switch item’s location. This should currently display “ON”.
c. Turn the machine’s keyswitch to the off position.
d. Wait for the web page to update. The Key Switch value should change to “OFF”.
e. Turn the machine’s keyswitch to the on position.
f. Wait for the web page to update. The Key Switch value should change to “ON”. This is
a positive indication of proper keyswitch state sensing.
5. Verifying that DCM300 is communicating with the VisionLink platform
a. Power unit with keyswitch on and contact Trimble for verification in the VisionLink
application
6. Verifying that DCM300 is communicating with machine’s J1939 bus
a. Power unit with CANbus active and contact Trimble for verification in the VisionLink
application
b. Carl Thompson (303) 931 – 1281 & Tony Bowers
Testing the operation of an DCM300 device requires access to the Trimble VisionLink software
application. The application could be on a portable computer with Internet access that is in the
vicinity of the installation. Alternatively, an assistant could operate the software at a remote
location and report the device interaction by cellular phone. An important consideration is that
the DCM300 device is intended to provide data to an equipment manager in an office setting.
The device does not normally provide information for the equipment operator or for use at the
machine itself.
Verifying Positioning and Communications
Launch the VisionLink application using administrator credentials. Locate the serial number of
the newly installed device in this software. Go to the Asset Details page. The last device
position will be from the time that the machine was moved to a clear sky view area or newer. A
screen similar to the one shown in Figure 7 below indicates recent communications and proper
positioning. The “Date Last Reported” item in the lower left of the screen should be from a time
within the last few minutes. The position on the map should be close to the actual machine
position.
Figure 6 - VisionLink Asset Details Page
Verifying Ignition Sense
Start the engine in the newly-equipped asset. Let the engine run for approximately thirty
seconds then turn the ignition off. The VisionLink Device asset details page will contain
messages indicating this sequence of engine operation.
Verifying Digital Inputs
Start the asset’s engine again. Trigger any installed digital inputs with at least a thirty second
active period. Turn the asset ignition off. The VisionLink asset details page will contain
messages indicating this sequence of digital input operations.
