Astra Telematics - AT241 Configuration

This page documents the public configuration context for using the Astra Telematics AT241 with Plaspy. It focuses on the practical server settings and example commands you can use to point the device at Plaspy so the tracker can report location, telemetry, and events into the Plaspy platform.

Plaspy uses shared server settings across supported devices and automatically detects the tracker protocol. Manufacturer-side setup steps for the AT241 can vary by firmware revision, hardware variant, installation type, and vendor tools; this page highlights the common public settings and an SMS-based command flow included in the device documentation.

Configuration Overview​

The goal of configuration is to prepare the AT241 so it reliably communicates with the Plaspy server endpoint and appears in your Plaspy account for live tracking and reporting. For many deployments the AT241 is configured using the manufacturer tools or SMS commands to set the operator APN, the server address, and the server port so cellular GPRS or LTE links can deliver telemetry to Plaspy.

  • Set the device APN, optional APN username and password if required by the mobile operator.
  • Configure the device to report to the Plaspy server using the provided server domain or IP and the shared Plaspy port.
  • Choose UDP or TCP transport on the device if it requires a transport selection; Plaspy will accept either and will automatically detect the protocol.
  • Validate that the tracker establishes a GPRS or cellular data session, reports location, and becomes visible in Plaspy.
  • Use SMS or vendor configuration tools to apply settings when the device is not connected to a handset or USB interface.

Plaspy Server Settings​

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

Typical Requirements Before Setup​

  • A powered AT241 device properly installed or accessible for initial configuration.
  • A working cellular SIM with an active data plan and SMS capability if you plan to use SMS commands.
  • Access to the manufacturer configuration method such as SMS commands, vendor mobile app, or PC configuration tool supplied by Astra Telematics.
  • APN details from the mobile operator including optional username and password when required.
  • A Plaspy account and access to the platform to verify device reporting and validate data ingestion.
  • Basic knowledge of whether to use UDP or TCP for your deployment; the device may require an explicit selection.

How This Tracker Connects to Plaspy​

When configured with the Plaspy server settings, the AT241 uses its cellular link to open a connection to the shared Plaspy endpoint and transmit GNSS and I/O events. Plaspy ingests those packets and maps device events into live tracking, geofencing, and reporting features.

  • The tracker is pointed at the Plaspy server endpoint d.plaspy.com or directly to 54.85.159.138 and sends data to port 8888.
  • The device can use either UDP or TCP transport as configured; Plaspy accepts both and will automatically detect the protocol in use.
  • Location updates, motion and I/O events, and alarms are forwarded to Plaspy for real-time display and historical playback.
  • Regular connectivity and heartbeat messages help Plaspy determine device online status and support operational monitoring.
  • After successful configuration and network registration, the device should appear in Plaspy and begin reporting.

Common Configuration Workflow​

  1. Access the official Astra Telematics configuration method such as the SMS command interface, the vendor mobile tool, or the PC configuration utility.
  2. Enter the Plaspy server address by specifying d.plaspy.com or the IP 54.85.159.138 in the device server setting.
  3. Set the server port to 8888, noting that Plaspy uses the same port for all supported devices.
  4. Choose UDP or TCP on the device if a transport selection is required.
  5. Configure the operator APN and, when needed, the APN username and password so the device can open a data session.
  6. Apply or save the configuration and restart the device if the firmware requires a reboot to apply changes.
  7. Validate the device reports to Plaspy by checking device status and location in your Plaspy account.

Example Configuration Commands​

The AT241 documentation provides an SMS-based command set for basic network and server configuration. These commands are sent as plain text SMS messages to the device telephone number. Preserve the placeholders when you substitute real values.

  1. Set the operator APN
$APAD,[apn]
  1. (Optional) Set the APN username when the operator requires it
$APUN,[apnu]
  1. (Optional) Set the APN password when the operator requires it
$APPW,[apnp]
  1. Set the GPRS server to the Plaspy server IP
$IPAD,54.85.159.138
  1. Set the server port to the shared Plaspy port
$PORT,8888

Notes about placeholders:

  • [apn] is the mobile operator APN name required for a cellular data session.
  • [apnu] is the APN username if the operator requires authentication.
  • [apnp] is the APN password if required.
  • APN username and password commands are conditional and only needed when your carrier uses APN authentication.

Configuration Notes​

  • Firmware and tool differences can change exact command syntax and required reboot steps; always confirm commands against the device firmware version you have.
  • SMS-based setup is useful for in-field devices without a direct software connection, but vendor PC tools or mobile apps can provide bulk configuration and verification for fleet installs.
  • When choosing TCP versus UDP consider your network constraints and the device firmware behavior; Plaspy will accept either and auto-detects protocol, but some installations prefer one transport for firewall or reliability reasons.
  • All Plaspy integrations use the same port 8888 which simplifies device provisioning across large fleets.
  • Verify operator APN details and test data connectivity before relying on automated reporting.

Why Use Plaspy with This Configuration​

Using the AT241 with Plaspy gives fleet managers and asset operators a straightforward path to real-time location and event visibility. The AT241’s rugged design, flexible I/O, and multi-generation cellular support make it well suited to demanding vehicle and equipment deployments, while pointing the device at Plaspy enables immediate ingestion of GNSS coordinates, motion events, and alarm conditions into a centralized fleet management workflow.
