LMU-4200™ Hardware and Installation Guide 2 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. 2.1 Preparing for Installation Be sure you have received all the LMU components you need.
LMU-4200™ Hardware and Installation Guide 2.2 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-4200™ Hardware and Installation Guide 2.2.2 Placement of Antennas There are effectively three options for placements of an antenna: Roof-mount (magnetic or thru-hole) Glass-mount Covert (e.g. under the seat, dash, etc…) 2.2.3 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.
LMU-4200™ Hardware and Installation Guide 7 Examples of good and poor GPS antenna placements The received signal levels at the GPS antenna from the satellites are very low in power (approximately -136 dBm), so any blockage of the antenna can affect the quality of the location computed by the receiver. Kinks or tight knots in the antenna cable can also prevent the GPS receiver from operating properly.
LMU-4200™ Hardware and Installation Guide You may find it useful to be able to view the LEDs periodically to make sure that the LMU is operating properly. If at any time you should encounter a problem with the LMU, you may need to read the LEDs in order to troubleshoot the problem. If you cannot fix the LMU yourself, you will need to provide the LED information to CalAmp customer support. For information about how to interpret the LEDs, see the Status LED Behavior section. 2.2.
LMU-4200™ Hardware and Installation Guide 2.3 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: 2.3.1 Place the LMU unit in the vehicle. Typically, the LMU should be placed under the passenger seat or dashboard of the vehicle. Attach the LMU to the solid body of the vehicle, not to plastic panels.
LMU-4200™ Hardware and Installation Guide 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 8 - GPS Antenna Location 2.3.4 Mount the Comm. Antenna. When using separate Comm and GPS antennas, it is best to locate the Comm. Antenna at least 3 feet from the GPS antenna. Ensure that the cable is not crushed during installation or normal vehicle operation. Again, the Comm.

LMU-4200™ Hardware and Installation Guide 2.4 I/O Descriptions The LMU-4200™ provides the following inputs and outputs (I/O): Digital Inputs Input 0: Ignition Sense (Always biased low) Input 1: Generic Digital Input (Biased high or low/ S-158 Bit 1) NOTE: Shared with Output 1. Function selection controlled by S-159 Input 2: Generic Digital Input (Biased high or low/ S-158 Bit 2) NOTE: Shared with Output 2.
LMU-4200™ Hardware and Installation Guide 2.4.1 Ignition and Inputs The LMU-4200™ provides up to 4 inputs on its own and up to 7 with the ioPOD. These 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 10k. One of these inputs is dedicated to sensing the vehicle’s ignition status to provide for flexible power management.

LMU-4200™ Hardware and Installation Guide 2.4.2 3-Axis Accelerometer Input The LMU-4200™ 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. 2.4.
LMU-4200™ Hardware and Installation Guide 2.4.4 Status LEDs The LMU-4200™ is equipped with two Status LEDs, one for GPS and one for COMM (wireless network status).
LMU-4200™ Hardware and Installation Guide Verification via SMS The current Comm, GPS and Inbound status of either a CDMA or 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-4200™ 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-4200™ 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.
