CalmAmp - LMU-3200 Configuration

This page documents the public configuration context for using the CalmAmp LMU-3200 with Plaspy. It collects the practical server settings and SMS configuration commands that are publicly available and explains how to prepare the device to report to the Plaspy platform. Use this guide alongside official CalmAmp documentation and your installer tools.

Plaspy uses shared server settings across supported devices and automatically detects the tracker protocol so a single server configuration works for multiple models. Exact manufacturer side setup steps can vary by firmware, hardware revision, installation type, and vendor tools, so follow the device manufacturer instructions when they differ from the examples shown here.

Configuration Overview​

The goal of this configuration process is to prepare the LMU-3200 to communicate reliably with Plaspy, confirm connectivity, and enable visibility in the Plaspy platform. For LMU-3200 units the publicly documented approach often uses SMS configuration commands or the manufacturer management tools to set APN and the Plaspy server endpoint.

  • Set the mobile data APN and credentials so the device can establish a GPRS data session.
  • Configure the device to report to Plaspy using the shared server endpoint and port.
  • Choose the transport mode supported by the device if required and save the configuration.
  • Reboot or apply settings so the device initiates a connection and begins reporting.
  • Verify settings and confirm the device appears in Plaspy.

Plaspy Server Settings​

Use the following public Plaspy server settings when configuring the LMU-3200:

  • Server domain d.plaspy.com
  • Server IP 54.85.159.138
  • Port 8888
  • Transport support for UDP or TCP
  • Plaspy automatically detects the tracker protocol

Note that Plaspy uses the same port for all supported devices and protocol detection is handled on the platform side.

Typical Requirements Before Setup​

  • A powered and installed LMU-3200 unit with an active SIM that supports mobile data and SMS.
  • Access to the device identifier information such as the MID returned by the device using the manufacturer verification commands.
  • Permission to send SMS commands to the device or access to the CalmAmp management tools used to set parameters.
  • APN, APN username, and APN password values from the mobile operator when required.
  • A plan for validating connectivity once settings are applied, including logins to Plaspy for verification.
  • Basic knowledge of the device firmware or access to CalmAmp support resources for firmware specific instructions.

How This Tracker Connects to Plaspy​

When configured for Plaspy, the LMU-3200 is set to send its location and event data to the shared Plaspy server endpoint and port. Plaspy collects those messages, identifies the tracker protocol automatically, and presents location and device events in the platform.

  • The device is configured to point at either d.plaspy.com or the Plaspy server IP 54.85.159.138.
  • Outbound messages are sent to port 8888 where Plaspy receives them.
  • Transport can be UDP or TCP depending on device requirements and installer preference.
  • Plaspy performs automatic protocol detection so manual protocol selection on the server is not required for the platform to interpret messages.
  • Once reporting begins the device becomes visible in Plaspy for monitoring, events, and diagnostics.

Common Configuration Workflow​

  1. Access the official CalmAmp configuration method or management tool for the LMU-3200 such as SMS commands or the vendor management system.
  2. Retrieve the device MID or identifier as required by the device using the device verification command so you can reference the correct unit.
  3. Enter the Plaspy server domain d.plaspy.com or the Plaspy server IP 54.85.159.138 into the device configuration.
  4. Set the server port to 8888 in the device configuration.
  5. Choose the transport mode UDP or TCP if the device requires an explicit transport selection.
  6. Configure the APN and any APN credentials required by the mobile operator so the device can use GPRS data.
  7. Apply or save the configuration and restart or reboot the device if required to apply changes.
  8. Validate that the device reports to Plaspy by checking the device status in Plaspy and using the device verification commands to confirm settings.

Example Configuration Commands​

The LMU-3200 can be configured by sending SMS messages using the device MID returned by the device verification command. The public commands below are provided in the order they are commonly applied. Keep the placeholders as shown and replace them with your operator values.

  • Retrieve the device MID for use with SMS configuration
!R0

Note: the device will reply with its MID which is a 10 digit identifier referenced when sending configuration SMS messages.

  • Set the operator APN
!RP,2306,0,[apn]
  • Set the APN operator username
!RP,2314,0,[apnu]
  • Set the APN operator password
!RP,2315,0,[apnp]
  • Set the GPRS server to the Plaspy server IP
!RP,2319,0,54.85.159.138
  • Set the server port used by Plaspy
!RP,769,0,8888
  • Reboot the tracker to apply changes
!R3,70,0

Label: Reboot command to apply configuration changes; perform this after saving settings.

  • Check device settings
!RO

Note: Placeholders explanation

  • [apn] is the mobile network operator APN
  • [apnu] is the APN username when required
  • [apnp] is the APN password when required

Send the SMS configuration messages according to your installer process and referencing the MID the device returns. The exact SMS message format and whether the MID must prefix the command can vary by firmware and provisioning method, so follow the manufacturer instructions for the correct SMS syntax.

Configuration Notes​

  • Firmware and provisioning workflows can vary between hardware revisions and CalmAmp management tools such as PULS. Verify the correct command syntax for your firmware.
  • The device supports configuration by SMS in the public commands above but CalmAmp management portals or over the air updates may provide an alternative and centralized method.
  • Choosing UDP or TCP depends on installer preference and network conditions. Plaspy will accept either and will detect the protocol automatically.
  • Always confirm APN values with the mobile operator and test connectivity before deploying at scale.
  • Use the manufacturer documentation for any advanced PEG or OBD II configurations that are outside of the basic server and APN settings.

Why Use Plaspy with This Configuration​

Configuring the CalmAmp LMU-3200 to report to Plaspy gives organizations centralized visibility into location and device events across a mixed fleet using a single shared server configuration. The LMU-3200’s diagnostic and event capabilities combined with Plaspy’s protocol detection make it straightforward to collect vehicle and telematics data without per device server complexity.
