CalmAmp - LMU-2100 Configuration

This page covers the public configuration context for using the CalmAmp LMU-2100 with Plaspy. It consolidates the key server settings and practical setup information that you can apply when preparing the LMU-2100 to communicate with Plaspy. Where manufacturer-side configuration commands are publicly available they are included for clarity.

Plaspy uses shared server settings across supported devices and automatically detects the tracker protocol used by the device. Exact steps on the manufacturer side can vary by firmware, hardware revision, installation type, and vendor tools such as CalAmp PULS or SMS configuration methods, so treat the examples here as practical public guidance and verify device-specific procedures with the manufacturer.

Configuration Overview​

The goal of LMU-2100 configuration for Plaspy is to prepare the device to reliably send telemetry and event data to Plaspy's shared server endpoint so the device becomes visible and manageable in the platform. This typically includes setting the network APN, the server address and port, choosing an appropriate transport, and verifying the device reports correctly.

  • Configure the operator APN and any required credentials so the LMU-2100 has GPRS connectivity.
  • Point the device to Plaspy server settings so it sends location and event messages to the correct endpoint.
  • Choose the transport (UDP or TCP) if required and ensure the device uses Plaspy's common port.
  • Validate configuration and confirm the device reports to Plaspy so the unit appears in the platform.
  • Reboot or restart the device when required to apply settings and perform a final connectivity check.

Plaspy Server Settings​

Use the following public Plaspy settings when configuring the device:

  • Server domain d.plaspy.com
  • Server IP 54.85.159.138
  • Port 8888
  • Transport support for UDP or TCP; the device may be configured using either UDP or TCP on port 8888
  • Plaspy automatically detects the tracker protocol and all devices in Plaspy use the same port

These values are the shared endpoint and port used by Plaspy for supported trackers and should be entered on the device or via the manufacturer configuration interface.

Typical Requirements Before Setup​

  • Ensure the LMU-2100 has a valid mobile SIM with data enabled and the correct APN for the mobile operator.
  • Device has power and is in a location with cellular coverage to validate GPRS or alternative supported radio.
  • Access to the CalAmp configuration method expected for the unit such as SMS commands, PULS OTA, or the vendor provisioning tool.
  • The device ID (MID) or IMEI available for identification; the LMU-2100 can reply with its ID using manufacturer commands.
  • A way to receive and review device responses for verification (SMS replies or server-side logs).
  • Administrative access to Plaspy so you can confirm the tracker appears and starts reporting after configuration.

How This Tracker Connects to Plaspy​

Once configured, the LMU-2100 will send its telemetry and event messages to the shared Plaspy server endpoint and port so that Plaspy can display location, alerts, and status. Plaspy’s automatic protocol detection handles the tracker protocol so a single shared port is used across devices.

  • The device is configured to report to d.plaspy.com or 54.85.159.138 on port 8888.
  • Plaspy receives location updates and device events from the tracker for visibility in the platform.
  • Event rules generated by the unit (for example from the PEG engine) are transmitted and can be monitored in Plaspy.
  • Protocol detection in Plaspy identifies the tracker protocol automatically so separate protocol settings are not required on the Plaspy side.
  • Transport can be configured as either UDP or TCP on the device depending on installation needs.

Common Configuration Workflow​

  1. Access the official CalmAmp configuration method for the LMU-2100 such as SMS commands, PULS OTA, or vendor provisioning tools.
  2. Enter the Plaspy server address by using d.plaspy.com or the IP address 54.85.159.138 in the device configuration.
  3. Set the server port to 8888; remember that Plaspy uses the same port for all supported devices.
  4. Choose UDP or TCP on the device if it requires you to select a transport.
  5. Configure the operator APN and any APN credentials required so the device can establish GPRS connectivity.
  6. Apply or save the configuration and reboot or restart the device if required to apply settings.
  7. Validate that the device reports to Plaspy by checking device responses and confirming the unit appears in the Plaspy platform.

If you configure via SMS commands, follow the manufacturer command order and confirm replies for each step before proceeding.

Example Configuration Commands​

The LMU-2100 can be configured by sending SMS commands to the unit. The commands below are provided in the public model configuration and should be sent in the order shown when using SMS. The device ID used to target SMS commands is the MID 10 digits replied by the !R0 command.

  • Set the operator APN
!RP,2306,0,[apn]

Replace [apn] with your mobile operator APN.

  • Set the APN username (if required)
!RP,2314,0,[apnu]

Replace [apnu] with the APN username. Omit if your APN has no username.

  • Set the APN password (if required)
!RP,2315,0,[apnp]

Replace [apnp] with the APN password. Omit if not needed.

  • Set the GPRS server to Plaspy by IP
!RP,2319,0,54.85.159.138

This points the unit directly to Plaspy server IP. Alternatively use d.plaspy.com where supported by the device.

  • Set the server port (Plaspy common port)
!RP,769,0,8888

All devices in Plaspy use port 8888.

  • Reboot the tracker to apply settings (optional but common)
!R3,70,0

This reboot command is typically used to apply configuration changes; only use if required by your installation.

  • Check current settings on the device
!RO

Use this verification command to request and review the configured parameters.

Note: The !R0 command can be used to request the device MID which is required as the device identifier when addressing some SMS commands.

Configuration Notes​

  • Firmware and hardware revisions can change command syntax or supported parameters; verify the syntax against the device firmware version.
  • The LMU-2100 supports CalAmp PULS for OTA programming and the device may also accept SMS-based configuration as shown in the example commands.
  • Choose UDP or TCP based on network reliability and installation needs; Plaspy accepts either transport on port 8888.
  • All devices in Plaspy use the same port and Plaspy performs automatic protocol detection so platform-side protocol selection is not required.
  • When using SMS commands preserve placeholders such as [apn], [apnu], and [apnp] and replace them with values specific to your mobile operator.

Why Use Plaspy with This Configuration​
