CalmAmp - TTU-1200 Configuration

This page documents the public configuration context for using the CalmAmp TTU-1200 with the Plaspy platform. It summarizes the essential server settings Plaspy requires, explains the common setup workflow, and provides the publicly available SMS configuration commands included in manufacturer guidance. Use this page to prepare a TTU-1200 for integration into Plaspy and to validate connectivity once configured.

Plaspy uses shared server settings across supported devices and automatically detects the tracker protocol, but exact manufacturer-side steps can vary by firmware, hardware revision, installation type, and vendor tools. The TTU-1200 supports SMS and UDP messaging, and CalAmp also offers over the air device management with PULS for remote updates, so choose the configuration path that matches your device firmware and installation practice.

Configuration Overview​

The goal of this configuration process is to prepare a TTU-1200 so it can reliably send location and event data to Plaspy and appear in your fleet monitoring environment. Configuration typically includes setting the cellular APN, pointing the device to Plaspy server settings, choosing the transport method, and validating that the device reports successfully.

  • Configure the operator APN and any APN credentials required by the SIM carrier.
  • Point the device at the Plaspy server domain or IP so it can establish a TCP or UDP connection.
  • Set the shared Plaspy port used by all devices so messages are routed to the correct endpoint.
  • Select UDP or TCP transport according to device firmware and network reliability considerations.
  • Validate connectivity by checking device responses and observing the tracker reporting in Plaspy.

Plaspy Server Settings​

  • Server domain d.plaspy.com
  • Server IP 54.85.159.138
  • Port 8888 (this same port is used by all devices in Plaspy)
  • Transport support for UDP or TCP on port 8888
  • Plaspy automatically detects the tracker protocol when devices connect

These server values are the public Plaspy endpoints to use when configuring the TTU-1200 so the device can report into the Plaspy platform.

Typical Requirements Before Setup​

  • A charged and powered TTU-1200 unit with access to its SMS or manufacturer configuration channel.
  • A valid SIM card with data or messaging enabled and the correct APN information for the mobile operator.
  • Access to the device response ID (MID) as returned by the device with the !R0 command when using SMS configuration.
  • Manufacturer configuration method available such as SMS commands or CalAmp PULS if the device and account support OTA management.
  • Cellular coverage in the installation area to allow GPRS or supported cellular transport to reach Plaspy.
  • Basic familiarity with sending SMS commands to devices or access to the installer configuration tool recommended by the vendor.

How This Tracker Connects to Plaspy​

The TTU-1200 is configured to report location and event data to a Plaspy server endpoint and port so the platform can ingest and present telemetry for monitoring and alerts. Depending on how you configure the device, it will use UDP or TCP messaging over the cellular network, and Plaspy will identify the protocol automatically.

  • The tracker sends location updates and event messages to the shared Plaspy server endpoint.
  • Messages are directed to port 8888 which Plaspy uses for all devices.
  • The device may use UDP for lightweight message transport or TCP for a connection oriented session depending on configuration.
  • Plaspy automatically detects the protocol and processes incoming messages from the TTU-1200.
  • Once connected, the tracker becomes visible in Plaspy for real time tracking and operational monitoring.

Common Configuration Workflow​

  1. Access the official CalmAmp configuration method for your unit, either SMS commands or the CalAmp PULS OTA system as supported by your account.
  2. Enter the Plaspy server domain d.plaspy.com or the server IP 54.85.159.138 in the device server/GPRS settings.
  3. Set the server port to 8888. Note that Plaspy uses the same port across devices.
  4. Choose the transport method UDP or TCP if the device firmware requires a selection.
  5. Apply or save the configuration on the device or send the SMS commands to program the parameters.
  6. Restart or reboot the device if the configuration method requires it to apply settings.
  7. Validate that the device reports to Plaspy by checking device responses and confirming visibility in the platform.

If you prefer SMS programming, use the manufacturer SMS commands shown below. If you manage devices with PULS, use PULS to push equivalent parameters and firmware updates where available.

Example Configuration Commands​

The TTU-1200 can be configured by SMS using the commands documented by the manufacturer. The ID referenced in SMS commands is the MID, a 10 digit identifier returned by issuing the !R0 command to the device. Send these SMS messages from a phone number authorized to configure the device.

  1. Request the MID to identify the unit (useful to confirm the device ID before sending configuration commands):
!R0
  1. Set the operator APN (replace [apn] with your carrier APN string):
!RP,2306,0,[apn]
  1. Set the APN username if required by the operator (replace [apnu] with the APN username):
!RP,2314,0,[apnu]
  1. Set the APN password if required by the operator (replace [apnp] with the APN password):
!RP,2315,0,[apnp]
  1. Set the GPRS server to Plaspy using the public server IP:
!RP,2319,0,54.85.159.138
  1. Set the server port to Plaspy port 8888:
!RP,769,0,8888
  1. Reboot the tracker to apply changes (labelled here as a reboot step to refresh configuration):
!R3,70,0

Verification: check the settings configured on the device with:

!RO

Notes on placeholders:

  • [apn] is the carrier APN string required for GPRS data.
  • [apnu] is the optional APN username for carrier authentication.
  • [apnp] is the optional APN password for carrier authentication.
    Keep placeholders as provided and replace them with the operator credentials appropriate for your SIM card.

Configuration Notes​

  • The TTU-1200 supports SMS based configuration as well as remote management via CalAmp PULS when available; choose the method that matches your deployment and account access.
  • Firmware versions and hardware revisions can change parameter names or the required command syntax; confirm commands with the unit response and CalAmp documentation.
  • When selecting transport, UDP is typically lighter weight while TCP can provide session guarantees; Plaspy accepts either and auto detects the protocol.
  • Plaspy uses port 8888 for all devices so ensure that value is used consistently when programming multiple units.
  • Always verify APN credentials with your mobile operator to ensure the device can establish a GPRS/packet data session.

Why Use Plaspy with This Configuration​

Using the CalmAmp TTU-1200 with Plaspy gives fleets and asset managers a straightforward path to ingest location and event data from a long-life trailer tracking device. Configuring the unit to point to the Plaspy server endpoint and port enables centralized visibility, event reporting, and operational monitoring across devices and asset types.
