LMU-2x20™ Hardware and Installation Guide Configuration and Activation 3.5 Configuration Quick Start Guide This section details how to quickly get an LMU-2x30™ provisioned and configured to point at a specific server. It is assumed that a PEG script has already been created and is being managed through LMU Manager or PULS™, the CalAmp Maintenance System.
LMU-2x20™ Hardware and Installation Guide 3.6 Quick Start - General Config All LMU-2x30s™ must go through a common step during the configuration and provisioning process. Specifically, this is pointing the LMU to the LM Direct™ server, either via IP or a URL This configuration process is accomplished via a series of AT Commands. 1. 2. 3. 4. Power up the LMU-2x30™ Plug the serial cable into your laptop Open a terminal session to the LMU-2x30™ Enter the address of the LM Direct™ server.
LMU-2x20™ Hardware and Installation Guide 3.7 Auto provisioning of GSM LMUs For certain operators, the LMU can auto-populate the APN, username and password settings based on the Mobile Country Code (MCC) and the Mobile Network Code (MNC) of the SIM. Upon inserting a new SIM the APN, username and password will switch to the new SIM card's defaults if the MCC and MNC values change.
LMU-2x20™ Hardware and Installation Guide • Telstra Australia (MCC 505, MNC 01, 11, 71, 72) o APN 0 & 1: telstra.internet • Vodafone Ireland (MCC 272, MNC 01) o APN 0 & 1: isp.vodafone.ie o Username: vodafone o Password: vodafone • Vodafone New Zealand (MCC 530, MNC 01) o APN 0 & 1: internet o Username: guest o Password: guest • Vodafone UK (MCC 234, MNC 15) o APN 0 & 1: internet o Username: web o Password: web Unless otherwise stated, the username and password will be set to “dummy”.
LMU-2x20™ Hardware and Installation Guide 3.8 Activating a GSM LMU using AT Commands For a GSM/GPRS operator 3 you will get the LMU in one of two varieties, one with a SIM and one without. If you get an LMU without a SIM (which is the typical case) the operator will simply ask for the IMEI of the LMU. The IMEI (International Mobile Equipment Identifier) is printed on the bottom of the LMU under the LMU’s ESN. Again, DO NOT give the operator the ESN of the LMU.
LMU-2x20™ Hardware and Installation Guide The last item an operator may provide is a SIM PIN. The PIN is effectively a password to the device. The main difference here is that the PIN will restrict all the capabilities of the GSM device, where the SPC is used just for configuration. The activation sequence for a GSM LMU would therefore look as follows: AT$APP PARAM 2306,0, “myAPN.myOperator.
LMU-2x20™ Hardware and Installation Guide 3.9 Accessing the SIM The following instructions should be used when attempting to access the SIM in a GSM LMU-2x30™. When opening the LMU-2x20™ take care to not to touch the GPS Patch Antenna as an accidental ESD discharges may render it inoperable. 1. Remove the top plate of the LMU-2x30™. The LMU-2x30™’s enclosure is held together by 4 plastic clips.
LMU-2x20™ Hardware and Installation Guide 4. Insert the SIM into the LMU. Figure 13 - LMU-2x30™ - Partially Inserted SIM 5. Snap the LMU-2x30™’s cover back in place. V1.0.
LMU-2x20™ Hardware and Installation Guide 4 Installing the LMU The installation of the LMU and its antennas can have a major impact on the LMU’s performance. It is recommended that installers be familiar with the installation of GPS and cellular devices and are comfortable in a vehicle environment. 4.1 Preparing for Installation Be sure you have received all the LMU components you need.
LMU-2x20™ Hardware and Installation Guide 4.2 Plan The Installation Verify Power, Ground and Ignition. Be sure to check each source (power, ground and ignition) to ensure that the proper signaling exists. This is typically accomplished with a multi-meter. Before drilling any holes or running any wires, decide where each hardware component will be located (LMU, antennas, peripherals, etc.). Be sure that the cables to the LMU are not bent or constricted in any way.
LMU-2x20™ Hardware and Installation Guide 4.2.2 Placement of Antennas There are effectively three options for placements of an antenna: • Roof-mount (magnetic or thru-hole) • Glass-mount • Covert (e.g.
LMU-2x20™ Hardware and Installation Guide 4.2.2.1 Comm Antenna Placement Guidelines The Comm. Antenna must be located at least 20cm away from vehicle passengers, other personnel, or bystanders in order to comply with FCC radio frequency exposure limits. Typically, the Comm antenna used by the LMU for wireless service is a standard 3-dB gain whip. It mounts with standard mounts (i.e. thru-hole, magnetic mount or peel and stick) and requires a ground plane to work properly.
LMU-2x20™ Hardware and Installation Guide prevent the GPS receiver from operating properly. When laying out the antenna cable, care should be taken so that the cable is not subjected to crushing or strain. 4.2.2.3 Placement of Combination and Internal Antennas When dealing with combination antennas, it is more important to considered GPS performance over Comm performance. GPS signal strengths are much lower than those typically seen by cellular networks supported by the LMU.
LMU-2x20™ Hardware and Installation Guide 4.2.3 Access to the SIM (Subscriber Identity Module) Card When used in a GSM or iDEN network, each LMU uses a Subscriber Identity Module (SIM) card, which should be inserted before you install the LMU for the first time. The SIM card is attached to the main-board inside the housing of the LMU unit.
LMU-2x20™ Hardware and Installation Guide Two common methods are the use of Tamper Proof Sealant or creation of PEG Script to detect power loss or GPS antenna disconnections. V1.0.
LMU-2x20™ Hardware and Installation Guide 4.3 Installing the LMU in a Vehicle This section provides instructions for installing an LMU in a vehicle. Be sure to consider the design decisions described in the previous sections. When you are ready to begin installing the LMU, follow these steps: 4.3.1 Place the LMU unit in the vehicle. Typically, the LMU should be placed under the passenger seat or dashboard of the vehicle. LMUs with internal antennas should be placed to maximize their GPS performance.
LMU-2x20™ Hardware and Installation Guide Kinks or knots in the antenna cable can prevent the GPS receiver from operating properly. When laying out the antenna cable, take care that the cable is not subjected to crushing or strain. The ideal location is typically near the center of the vehicle’s roof. However, it is also desirable to locate the cellular antenna as far from the GPS antenna as possible. Figure 17 - GPS Antenna Location 4.3.4 Mount the Comm. Antenna.

LMU-2x20™ Hardware and Installation Guide 4.4.1 Ignition and Inputs The LMU-2x30™ provides up to 5 external inputs and one internal. The external inputs are protected from typical vehicle transients and can be directly connected to most vehicle level logical inputs from 4 volts up to the vehicle power input level (typically 12 VDC). Their input impedance is approximately 10kΩ. One of these inputs is dedicated to sensing the vehicle’s ignition status to provide for flexible power management.
LMU-2x20™ Hardware and Installation Guide Figure 21 - Sample Input Wiring V1.0.
LMU-2x20™ Hardware and Installation Guide 4.4.2 3-Axis Accelerometer Input The LMU-2x30™ supports an internal 3 Axis Precision Accelerometer as one of its discreet inputs. When the LMU is moved in any direction, the associated input will be in the High state. If the LMU’s accelerometer does not detect motion, then the input will be in the Low state. No external connections are required for this functionality to be operational. 4.4.3 Outputs The LMU’s outputs are designed to drive external relays.
LMU-2x20™ Hardware and Installation Guide 4.4.4 Status LEDs The LMU-2x30™ is equipped with two Status LEDs, one for GPS and one for COMM (wireless network status).
LMU-2x20™ Hardware and Installation Guide 4.5 Installation Verification In many cases it is desirable to verify that an installed LMU-2x30™ is working properly. That is, installers should verify that the GPS and communications functions of the LMU2x30™ are working properly before departing the installation site. In more robust cases, some key configuration settings such as the Inbound Address and URL should also be verified. Note that these processes are all based on issuing AT Commands to the LMU-2x30™.
LMU-2x20™ Hardware and Installation Guide 4.5.2 GPS Verification The next step is to verify that the GPS receiver is seeing enough satellites to obtain a valid GPS position. Again, installers have two choices on how to perform this verification. First, like the Comm Verification, there is a GPS status LED (i.e., the one closest to the SMA connector). If this LED is solid, then the LMU has found GPS service.
LMU-2x20™ Hardware and Installation Guide 4.5.3 Inbound Verification The last item to verify is that the LMU-2x30™ is sending data to the correct server. In general, this is a two-step process that will need the aid of an observer on the back end. That is, a technician will have to be logged in so they can monitor data coming into the backend mapping/vehicle management application.
LMU-2x20™ Hardware and Installation Guide 4.5.4 Verification via SMS The current Comm, GPS and Inbound status of a GSM LMU can be obtained via SMS provided you have access to an SMS capable phone or PDA. Using your handset, send the following SMS Message to the LMU: !R0 Within a few minutes, the LMU should return a response in the following format: APP: COM: [./d/D][./a/A][.
LMU-2x20™ Hardware and Installation Guide o [./L]: This field indicates if the LMU’s log is currently active. An ‘L’ indicates that the log is currently in use (i.e. one or more records have been stored) where a ‘.’ indicates the log is inactive. o [IP Address]: This is an optional field if and is only present if the LMU has established a valid data session. This field will contain the current IP address of the LMU as assigned by the wireless network. Note that if you see a value of 192.168.0.
LMU-2x20™ Hardware and Installation Guide o : This will be the type of Mobile ID in use by the LMU. The available types are, Off, ESN, IMEI, IMSI, USER, MIN and IP ADDRESS. • INB: o : This is the current IP address in use by the LMU. This value should match the IP address of your LM Direct™ server. o : This is the current UDP port the LMU will use to deliver its LM Direct™ data. This value should match UDP port you are using on your LM Direct™ server.
