About This User Guide Disclaimer: This guide contains information about the SCU. No representations or warranties are made as to the accuracy or completeness of the information contained herein. No representations or warranties are made as to the completeness and compliance of any installations that are performed using this guide. Purpose This guide contains product information for the SCU.
1 Overview The SCU is a smart antenna product manufactured by ORBCOMM. The SCU provides a low cost, versatile satellite connection for customer’s tracking and monitoring terminals through the ORBCOMM OGx interface. It is primarily targeted towards the construction equipment market. A single RS-232 port is available to communicate with the SCU. In addition, SCU utilizes a rugged, IP67 enclosure that house all electronics and power control.

3 Compliance FCC (United States of America) CFR47 PART 15 • FCC ID: xxxxxxxxxxxxxxxxx FCC Compliance Statement This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
4 Installation IMPORTANT READ ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING. FAILURE TO DO SO MAY CAUSE PERSONAL INJURY OR DAMAGE TO PRODUCT AND/OR PROPERTY. • • Review the product package and contents prior to beginning the installation. Take care when opening the packaging and removing items. If a return is needed you will want to return the product in its original packaging if possible.
Figure 3: SCU Mounting Location • Mount the SCU on a solid, stable surface that is clean and free of oil, dirt, and debris. • Fasten the SCU securely so that it is not loose and does not move easily. • Check that the SCU’s cable reaches the VTU before you drill any mounting holes. • Mount the SCU on a surface that does not get hotter than the maximum operating temperature (+85°C/+185°F). If the surface may get hotter, mount the SCU with a thermal barrier between it and the mounting surface.
Not within a radar beam • DO NOT mount the SCU where water may build-up or collect. • DO NOT mount the SCU close to an exhaust pipe due to the excessive heat and the potential for the exhaust pipe causing satellite blockage. • DO NOT mount the SCU close to air horns or any tractor roof hardware (for example, emergency lights) that could interfere with satellite communications. • DO NOT install the V SCU inside a truck under the roof liner. 4.3 Install the SCU 1. 2.
Figure 6: Antenna Cable Routing 4.4 Apply Power and Register the SCU When you apply power, the SCU goes into satellite search mode to acquire the OG2 network. This activity may take a few minutes to complete. The SCU must complete registration to operate. Once the SCU synchronizes itself with the network, it sends a registration message to the OG2 network. The SCU will not register until it has a connection to the satellite.
APPENDIX A Troubleshooting The following section contains troubleshooting information. Situation : SCU Does Not Register or Report On application of external power, the SCU should register with the satellite and send a report. Note: The SCU must be visible to the satellite to register with the network and registration normally takes a few minutes. If the SCU fails to register or report: • Ensure that the SCU has a clear line-of-sight to the satellite.
