Diagnostics

If your CalAmp device is equipped with status LEDs then please check their status. Both the green GPS and orange Communications LEDs should be solid. If the green LED is off or blinking then no valid GPS position could currently be determined and therefore no positions will be updated on the portal. If the orange LED is off or blinking then no data connectivity has been acquired and therefore no communications will occur with the portal whatsoever.

  • In the case of the orange Communications LED not being solid, the first step should be to confirm that the cellular data settings are correct for the SIM card being used.
  • In the case of the green GPS LED not being solid, it often takes several minutes for the initial GPS position to be acquired and a GPS time sync to occur.

Setup

The Calamp devices are managed remotely via a central repository, but the devices must be programmed with the APN information before they can connect to the repository. To program a terminal that is new, or changing network operators, do the following:
  • Connect the Calamp via a serial port at 115200 bps, 8N1
  • Connect via terminal software such as Hyperterm, putty, or screen
  • Enter the following commands:
    1. AT$APP DEBUG ON
    2. AT$APP PARAM 768,0,66.165.183.84
    3. AT$APP PARAM 769,0,4763
    4. AT$APP GPRS CONTEXT 0 "{APN}"
    5. AT$APP PARAM 2314,0,"{APN Username}"
    6. AT$APP PARAM 2315,0,"{APN Password}"
    7. AT$APP GPRS CONTEXT 1 "{APN}"
    8. AT$APP PARAM 2314,1,"{APN Username}"
    9. AT$APP PARAM 2315,1,"{APN Password}"
    10. AT$APP PARAM 1024,35,255,1
    11. AT$APP PEG ACTION 70 0
  • The unit will now reboot. Once the terminal is restarted, enter the following command to force an immediate connection:
    1. AT$APP PEG ACTION 49 129
  • The unit will now download the script from the central repository and begin reporting. This can take up to 30 minutes in poor network coverage.


SMS Setup

The APN information can also be configured via SMS if a serial connection is not an option or it needs to be changed remotely:

  • APN:
    • !RP,2306,0,{APN}
  • APN Username:
    • !RP,2314,0,{APN Username}
  • APN Password:
    • !RP,2315,0,{APN Password}
  • Server IP Address for:
    • (32 bit LMU) !RP,768,0,66.165.183.84
    • (8 bit LMU) !RP,2319,0,66.165.183.84
    • (8 bit LMU) !RP,2319,1,66.165.183.84
  • Server UDP Port:
    • !RP,769,0,4763
  • Reset Device:
    • !R3,70,0
  • Send Maintenance Report (to download configuration updates):
    • !R3,49,129

Upgrading Firmware

Use a serial terminal program such as HyperTerm with the YModem protocol

  • If you do not have HyperTerminal you can use a free utility here: http://en.sourceforge.jp/projects/ttssh2/releases/

  1. Open the terminal program (HyperTerm) and connect to the serial port at 115200 8N1
  2. Enter "ATDNLD" and the unit will be ready for the file transfer
  3. Using the YModem protocol, send the firmware binary to the unit

Firmware: LMU-GSM-170-30g.bin LMU-26xx and LMU-27xx GSM ONLY

Firmware: LMU-HSPA-176-33b.bin LMU-4x5x Iridium and GSM

Updating Configuration Locally

Download this AppendCRC16toBin.exe program to convert scripts to directly loadable files

  • If you do not have HyperTerminal you can use a free utility here: http://en.sourceforge.jp/projects/ttssh2/releases/

  1. Start here to export your script from LMU Manager. If you already have a script ready, skip to "Loading the script" below.
    1. Export the script from LMU manager to a CSV
    2. Open Command prompt and enter 'AppendCRC16toBin.exe' and then the name of the script file you want to convert
    3. Once this has finished it will have overwritten the existing script file and added characters at the end of the parameter list.
  2. Loading the script
    1. Using HyperTerm
      1. Open the terminal program (HyperTerm) and connect to the serial port at 115200 8N1
      2. Enter "ATDSCFG" and the unit will be ready for the file transfer
      3. Using the YModem protocol, send the configuration file (.csv) to the unit
      4. Press 'Send' button. You should see a list of the records being written.
    2. Using Tera Term
      1. Open the terminal program (Tera Term) and connect to the serial port at 115200 8N1
      2. Enter "ATDSCFG" and the unit will be ready for the file transfer
      3. Go to File -> Transfer -> YMODEM -> Send and select the configuration file (.csv) to send to the unit
      4. Press 'OK'. You should see a list of the records being written.

Sensors and Accumulators

The platform is by default setup to accept temperature in accumulator 0 and fuel level in accumulator 1.

The temperature is received in Celsius and is multiplied by 16.

The fuel level which is translated to a voltage is multiplied by 1000. IE 4800 translates to 4.8V

Fuel

The Calamp series can be connected to a VDO device which translates the fuel level with a tank profile into a sliding scale voltage of 0 to 10 volts which represents a fuel level of empty to entirely full.

The Ultrasonic Fuel Sensor UL-200 is also supported.

1-Wire Sensors

The Calamp series supports 1-Wire temperature sensors. Temperature sensors based on the DS18B20 support a single sensor, and the DS28EA00 supports up to 8 sensors in a chain.

  • Wire HTS Sensor Red to 5V (Pin 9: Orange)
  • Wire HTS Sensor White/Black to GND or 1BB GND (Pin 1 or 16: Black)
  • Wire HTS Sensor Yellow to 1BB Data (Pin 17: White/Blue)

LMU-2xx0

To connect a single temperature sensor, connect the DATA pin of the temperature sensor which is typically white on a 4 wire model and red on a 2 wire model to the White/Blue wire on the Calamp. Then connect the GND wire which is typically black to any ground/black wire of the Calamp.

Notes

  1. To enable the 1-wire bus the S register 171 must be set to 65. Ex: "ATS171=65"
  2. To push the temperature sensor data to the accumulator, the PEG Action Move Temp Sensors to Accumulator (93) can be used. Ex: "AT$APP PEG ACTION 93 0" sets temperature sensor 0 to push its value to accumulator 0
  3. To transmit the accumulator over the air, the Accumulator Number (772, 773) must be set to the number of accumulators to transmit under Report Contents > Event Report Optional Contents > Accumulator Number in LMU Manager: Ex: 1
