CalmAmp - LMU-2700 Configuration

This page covers the public configuration context for using the CalmAmp LMU-2700 with the Plaspy platform. It summarizes the shared server settings Plaspy expects, shows the common SMS commands published for LMU-2700 setup, and explains the typical workflow to prepare the device for reporting to Plaspy. Use this guide to understand what to change on the device and how Plaspy receives data from the tracker.

Plaspy uses a single shared server endpoint and port for supported devices and automatically detects tracker protocols when devices connect. Manufacturer-side setup steps for the LMU-2700 can vary by firmware, hardware revision, installation type, and vendor tools such as CalAmp PULS or SMS configuration. The examples below reflect public commands and server settings; always cross-check current manufacturer documentation before final deployment.

Configuration Overview​

The goal of this configuration process is to prepare an LMU-2700 so it can reliably send telemetry and event data to Plaspy and be visible in the platform. For LMU-2700 units, configuration is commonly applied either over-the-air with manufacturer systems or directly by SMS commands when that method is supported.

  • Configure APN and GPRS settings so the unit can reach the Plaspy network endpoint.
  • Point the device to Plaspy server d.plaspy.com or the equivalent server IP to route telemetry into the platform.
  • Set the shared Plaspy port so the unit sends packets to the correct service port.
  • Choose UDP or TCP transport if the unit requires transport selection.
  • Reboot or restart the device when required so new settings take effect.
  • Verify settings and confirm the device is reporting to Plaspy before finalizing installation.

Plaspy Server Settings​

  • Server domain: d.plaspy.com
  • Server IP: 54.85.159.138
  • Port: 8888
  • Transport: the device may be configured to use UDP or TCP on port 8888
  • Plaspy behavior: all devices in Plaspy use the same port and Plaspy automatically detects the tracker protocol when the device connects

Typical Requirements Before Setup​

  • A powered LMU-2700 installed or accessible for configuration and testing.
  • An active SIM with data enabled and correct APN settings for the mobile operator if using cellular data.
  • Access to the device configuration method you will use such as SMS setup, CalAmp PULS, or the official CalAmp configuration tools.
  • A way to receive or observe device responses (SMS replies, serial console, or platform connectivity logs) to confirm configuration changes.
  • Awareness of the device firmware version and any vendor notes that affect command syntax or available features.
  • Administrative access to the fleet platform to confirm the tracker becomes visible in Plaspy after setup.

How This Tracker Connects to Plaspy​

The LMU-2700 sends position and event messages from the vehicle to Plaspy by connecting over mobile data to the configured server endpoint and port. Plaspy receives incoming connections on the shared endpoint and maps the device to your account once the device transmits the expected protocol data.

  • The tracker is configured to report to the shared Plaspy server endpoint and port (d.plaspy.com or 54.85.159.138 on port 8888).
  • The device can use either UDP or TCP transport to send telemetry depending on configuration choices.
  • Plaspy automatically detects the tracker protocol so manual protocol selection in the platform is not required.
  • Once reporting, location and event data from the LMU-2700 are processed for visibility and alerts within Plaspy.
  • Device-side PEG rules or accelerometer events configured on the LMU-2700 can generate event messages that are forwarded to Plaspy for monitoring.

Common Configuration Workflow​

  1. Access the official manufacturer configuration method or software (for example CalAmp PULS or SMS commands) for your LMU-2700.
  2. Enter the Plaspy server endpoint by specifying d.plaspy.com or the server IP 54.85.159.138 in the device GPRS/server settings.
  3. Set the server port to 8888 (all devices in Plaspy use the same port).
  4. Choose UDP or TCP transport if the device configuration requires selecting a transport protocol.
  5. Save or apply the configuration on the device using the manufacturer tool or by sending the required SMS commands.
  6. Restart or reboot the device if the workflow or commands indicate a reboot is required to apply settings.
  7. Validate that the device reports to Plaspy by checking for incoming connections or device visibility in the platform.

Example Configuration Commands​

The LMU-2700 public configuration supports SMS-based commands. The ID in these commands is the MID 10 digits returned by the initial !R0 command. Preserve the placeholders [apn], [apnu], and [apnp] when substituting your operator values.

To request the device ID (MID):

!R0

Set the operator APN (replace [apn] with your carrier APN):

!RP,2306,0,[apn]

Set the APN username (replace [apnu] with the username if required):

!RP,2314,0,[apnu]

Set the APN password (replace [apnp] with the password if required):

!RP,2315,0,[apnp]

Set the GPRS server IP to Plaspy:

!RP,2319,0,54.85.159.138

Set the server port to Plaspy port 8888:

!RP,769,0,8888

Reboot the tracker to apply changes (recommended after applying settings):

!R3,70,0

Check current settings on the device:

!RO

Notes on the commands above:

  • Commands are intended to be sent via SMS to the LMU-2700 as published in the public command list.
  • The device replies to commands and the MID returned by !R0 is used as the command target ID in some workflows.
  • Keep placeholders [apn], [apnu], and [apnp] intact when replacing with your operator values.

Configuration Notes​

  • Firmware differences and hardware revisions may change available command IDs or SMS syntax; verify the syntax with current CalAmp documentation for your firmware.
  • LMU-2700 supports SMS-based configuration as shown above, but many installations use CalAmp PULS or other vendor tools for OTA provisioning.
  • If the device requires a transport selection, test both UDP and TCP to confirm the best behavior for your deployment; Plaspy supports both.
  • Always confirm that the APN credentials you provide allow GPRS data sessions and that the SIM has data enabled.
  • Applying settings and performing a guided reboot helps ensure the tracker registers to the Plaspy endpoint after changes.

Why Use Plaspy with This Configuration​

Using Plaspy with the CalmAmp LMU-2700 provides a straightforward way to centralize fleet tracking data from a proven vehicle tracking unit. The shared Plaspy server endpoint and automatic protocol detection simplify integration, while the LMU-2700's event capabilities and OTA management options give flexibility for both initial deployment and ongoing device maintenance.
