Purpose
This guide contains product information for the SCU. The intended audiences
for this guide include field support personnel, product evaluators, and
certified third-party personnel. It is particularly intended for personnel who
are responsible for system installation and activation. In addition, and as is
appropriate, this guide may be used for training purposes.
Cautions Concerning Servicing the Device
CAUTION: The equipment must be turned off when service work is required.
CAUTION: Remove the cable from the negative terminal of the reefer battery and
secure the cable to prevent accidental contact before performing any
installation or service procedure. Only trained service personnel should
perform the procedures outlined in this manual. These procedures may allow
exposure to high electrical energy that could result in electric shock and
injury to untrained personnel during servicing, maintenance, and installation
of the unit.
CAUTION: To avoid personal injury, the battery should be disabled by
disconnecting the negative terminal cable prior to installation or servicing.
CAUTION: Be aware of your working environment. Take appropriate steps to
ensure that the SCU cable harness and especially its connectors are not
exposed to soil, water, or other contaminants that may be present at the
installation site.
WEEE Statement
Disposal of this product should be handled according to all national laws and
regulations.
The mark shown to the right is in compliance with Waste Electrical and
Electronic Equipment Directive 2002/96/EC (WEEE). The mark indicates the

Overview
The SCU is a smart antenna product manufactured by ORBCOMM. The SCU provides a low-cost, versatile satellite connection for customers’ 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 houses all electronics and power control. An external antenna interfaces through an IP67 RF connector providing satellite connections. The SCU is powered externally through the main connector. This guide provides information required for a successful, reliable installation and operation of the SCU on a vehicle, boat, or another platform. This guide does not address the SCU commissioning procedures as these procedures are performed by Orbcomm’s customers.

Installation
IMPORTANT
READ ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING. FAILURE TO DO SO MAY CAUSE
PERSONAL INJURY OR DAMAGE TO THE 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.
- This instruction guide is provided as a GENERAL installation guide; some assets vary dimensionally and may require additional steps.
- The manufacturer and/or distributors do not accept responsibility for third-party charges, labor, and or third-party replacement modifications. Some modifications may void the factory warranty.
- Exercise due diligence when installing this product. ORBCOMM does not accept any responsibility for asset damage or personal injury resulting from the installation of this product. Careless installation and operation can result in serious injury or equipment damage.
- All liability for installation and use rests with the owner/operator.
- Always make sure you have a clean, dry, and well-lit work area.
- Always ensure products are secure during disassembly and installation.
- Always take steps to protect yourself when drilling, cutting, and grinding because this may create flying particles that can cause injury.
- Thoroughly inspect the area to be drilled, on both sides of the material, prior to modification, and relocate any objects that may become damaged.
- Always route electrical cables carefully. Avoid moving parts, parts that may become hot and rough, or sharp edges.
- Make sure to fully understand the product, its intended use, and operation prior to use.
CAUTION: The main product label is located on the bottom/underside of the device. This label may not be visible after a bottom mount installation.
Gather the Required Tool and Components
The following components are available from ORBCOMM:
-
AN SCU
The following components are customer supplied for an installation: -
customer telematics unit (VTU) cable harness
-
customer antenna with the antenna cable
Each SCU has a unique serial number, termed a mobile ID, used by ORBCOMM to
register it on the OG2 network. This is a 15-digit alphanumeric identifier in
the format “NNNNNNNNSKYXXXX” The mobile ID is located on the SCU label and on
the shipping box.
Record this mobile ID before the SCU is installed. You need it later to
activate the SCU on the network.
Note: The SCU may be activated on the network prior to or after shipping based on the customer’s agreement.
Review the Mounting Guidelines
CAUTION: It is very important for installers to install the SCU in a safe and secure way to avoid danger or damage to persons or property.
-
Mount the SCU on a flat surface in a protected location within the vehicle cab, within the vehicle’s telematics compartment next to the VTU.
-
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.
-
Mount the SCU antenna where it has a clear view of the sky/satellite. For a mobile installation, this means that it is preferable to install at the highest point on the vehicle where it has a clear view of the sky in all directions.
-
DO NOT mount the SCU close to other electrical equipment due to possible radiated and/or conducted electromagnetic interference.
-
DO NOT mount the SCU close to radar or other communications antennas. Use the following guidelines:
1 m from VHF/UHF antenna
3 m from the loop antenna
4 m from MF/HF antenna
5 m from other satellite antennas
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.
Install the SCU
- Use the enclosure as a template to mark the installation location for the SCU. Ensure that the hole positions are marked.
- Install three mounting bolts in the mounting location.
- Position the SCU on the mounting bolts, and then fix the enclosure to the vehicle with nuts. The fixing bolt size is M6.
- Torque the fixing bolts to 10 ± 1.5 Nm (M6 Medium torque, Property class 8.8).
- Connect the SCU to the VTU with the cable harness.
- Connect the antenna cable to the SCU and route the antenna cable to the previously installed antenna.
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. The OG2 network records the registration message and forwards the registration message to the user’s application. The OG2 network sends an acknowledgment message over the satellite to the SCU. The SCU is now available to send and receive messages via 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. The SCU must operate outdoors and be unobstructed by buildings, forest canopy, and rock cuts.
- Check that no objects or debris are touching the SCU antenna and blocking transmission.
- Verify with your supplier that the SCU is assigned to your account and registered (that it is sending and receiving) and that the OG2 network is operating properly. Replace the SCU if the earlier checks fail to uncover the problem.
