Carscop - CCTR-700 Protocol

This page documents the public protocol context for using the Carscop CCTR-700 tracker with the Plaspy platform. It focuses on high level communication and integration considerations that are relevant when routing device data to Plaspy and does not expose proprietary or firmware internal details. The goal is to help technical users understand how the device reports location and status to a third party service like Plaspy.

The Carscop CCTR-700 reports position data via SMS or GPRS and stores history locally when network coverage is unavailable. Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol, but exact protocol behavior can vary by firmware version, hardware revision, and manufacturer implementation. For Plaspy integration the public endpoint and transport settings are documented below and are common across supported devices.

Protocol Overview​

At a high level the tracker reporting protocol defines how the CCTR-700 identifies itself, encodes position and alarm events, and transmits those records to a remote server or via SMS. For integration with a cloud platform such as Plaspy the important aspects are reliable network transport, unique device identity in reports, and the ability to send live and historical location data.

  • The protocol governs how the device communicates location, timestamp, and basic alarm states to a remote endpoint.
  • Reporting can use GPRS data connections to send messages to a server or fall back to SMS for ad hoc queries and alerts.
  • Device identity and basic telemetry are included in each report so a platform can associate messages with a specific tracker.
  • The tracker can store a history of points locally and upload them when a data connection is available.
  • Alarm and sensor signals such as shock or movement are transmitted as events so the platform can trigger notifications.
  • Transport reliability and device configuration determine how frequently and how completely history is delivered.

How Plaspy Detects the Protocol​

Plaspy receives data from many device models and uses common network settings to accept reports. When a properly configured device sends data to the Plaspy endpoint the platform automatically determines the device protocol and routes messages into the appropriate parser and device record. In most cases you do not need to select a protocol in Plaspy if your device is correctly set to report to the Plaspy endpoint.

  • Plaspy server domain for device reporting is d.plaspy.com which resolves to the service endpoint.
  • Plaspy server IP is 54.85.159.138 for cases where an IP target is required.
  • The service listens on port 8888 and accepts tracker connections on that single port for all supported devices.
  • Plaspy automatically detects the tracker protocol once the device sends identifiable reports to the endpoint.
  • Users typically configure the tracker to point to d.plaspy.com or the server IP and do not need to choose a parser by hand.
  • If a device is misconfigured or uses a custom firmware variant, reports may not be recognized and additional configuration review is required.

Transport and Connection Context​

The CCTR-700 supports GPRS data transmission and SMS, and can be configured to use UDP or TCP for data connections. For Plaspy integration it is important to configure the device transport and destination consistently with the platform settings so reports arrive reliably.

  • Devices may be configured to use either UDP or TCP on port 8888 depending on the tracker firmware and operator preference.
  • Point the device to the domain d.plaspy.com or to the IP 54.85.159.138 when a numeric target is required.
  • Plaspy uses port 8888 for device reporting and all devices in Plaspy use the same port so a single outbound setting works for multiple models.
  • GPRS is the primary transport for live data and bulk history uploads, while SMS is useful for direct queries and fallback messages.
  • Ensure APN and GPRS credentials on the CCTR-700 are correct for the SIM in use so the device can reach d.plaspy.com reliably.
  • Network and operator behavior can affect delivery timing so consider transport selection and retry settings on the device.

Protocol Compatibility Notes​

  • The CCTR-700 can communicate via SMS or GPRS but exact message content and optional features can vary with firmware version.
  • Hardware revisions and manufacturer customizations sometimes change available commands or event reporting; verify the exact device revision when troubleshooting.
  • Transport choice matters: some firmware defaults use UDP while others prefer TCP, so match the device setting to the Plaspy endpoint configuration.
  • Local logging and memory behavior such as the 32768 point history buffer may affect how and when historical data is uploaded.
  • Manufacturer configuration tools or default APN settings can prevent successful GPRS uploads if not adapted to the operator.
  • Always validate the device reporting address and transport after any firmware update or hardware swap.
  • When in doubt consult manufacturer documentation for model specific options that affect reporting behavior.

Why Protocol Understanding Matters​

Knowing how the device protocol behaves helps ensure accurate setup, predictable event handling, and reliable historical data delivery when using Plaspy. Clear expectations about transport, identity fields, and alarm reporting reduce integration time and simplify operational troubleshooting.

  • Confirms the correct transport and destination so reports reliably reach d.plaspy.com on port 8888.
  • Helps identify whether missing data is due to network, device configuration, or firmware differences.
  • Enables planning for history uploads and periodic connectivity to avoid data gaps.
  • Guides configuration of alarms and sensor thresholds so events arrive as expected in Plaspy.
  • Reduces time spent on support by clarifying which behaviors are device side and which are platform side.
  • Supports safer rollouts when deploying multiple units across different firmware or hardware batches.

Why Use Plaspy with This Protocol​

Using Plaspy with Carscop CCTR-700 devices brings centralized visibility and operational control for organizations that need vehicle and asset monitoring. Plaspy accepts reports from the tracker over standard GPRS transport configured to the public Plaspy endpoint and provides mapping, event handling, and history replay using the device data.

Plaspy is designed to accept device connections to the shared endpoint at d.plaspy.com or to the server IP 54.85.159.138 on port 8888. All devices in Plaspy use the same port and the platform automatically detects the tracker protocol, simplifying device onboarding when trackers are configured to report to the Plaspy endpoint.
