Section 1 Introduction Related information Welcome to the DCM300 Installation Guide. This documnet describes how to install and verify initial operation of DCM300 M2M data radio. Even if you have installed and operated other telematics devices before, Trimble recommends that you spend some time reading this manual to learn about the special features of this product. If you are not familiar with GPS or vehicle telematics, visit the Trimble website (www.trimble.

Section 2 Device Overview In this section: • • • • Exterior Description Electrical Connector Antenna Connectors Mounting Hardware This section introduces the Trimble DCM300 M2M data modems. These units make it easy to receive status information from all types of construction assets to effectively manage them. The DCM300 telematics devices are ideal for the following applications: • • • Heavy earthmoving equipment – track type tractors, scrapers, motor graders, etc.

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.
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.
Section 3 Device Installation In this section: • • • • • • • Main Unit Location Determination Wiring Harness Route Planning Antenna Location Determination Main Unit Installation Antenna Installation Electrical Connections/Harness Installation SIM Card Installation This section describes the general procedure to install an DCM300 device and its necessary peripherals. The installer is expectected to have a basic knowledge of mechanical and electrical technical operations.

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.
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.
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.
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.
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.
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.
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.

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. b. c. d. e. Connect the operating PC to the Ethernet port on the DCM300. Turn the machine’s keyswitch to On. Open a browser on the PC. In the browser’s address bar, type 192.168.88.3. Press Enter.
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.
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.
