Ruptela - FM-Tco4 HCV Protocol
This page covers the public protocol context for using the Ruptela FM-Tco4 HCV with Plaspy. It explains how the tracker typically communicates with Plaspy servers in broad, non-sensitive terms and highlights the connection settings you will use to point devices at Plaspy for fleet tracking and telematics data collection.
The FM-Tco4 HCV is a feature rich tracker for trucks and heavy commercial vehicles that supports CANbus reading in J1708 and FMS standards, Dual Can operation, RS232 and RS485 ports, 1-Wire accessory support, and refrigeration unit monitoring. Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol, but exact device behavior can vary by firmware version, hardware revision, and manufacturer implementation, so confirm device-specific details with the manufacturer when needed.
Protocol Overview
The protocol used by the FM-Tco4 HCV defines how the tracker formats and sends its telemetry, status, and diagnostic information to a remote server. In public terms, the protocol is the set of device behaviors and message types that allow Plaspy to receive GPS positions, CANbus parameters, tachograph indicators, and accessory inputs without exposing manufacturer internals.
- Enables the tracker to identify itself and transmit location and vehicle telemetry to Plaspy.
- Carries CANbus and tachograph related data alongside basic GPS and I/O events.
- Facilitates remote configuration and occasional command acknowledgements when supported by the device.
- Allows accessory and sensor reports such as temperature and digital inputs to reach Plaspy for monitoring.
- Provides timestamps and status metadata that Plaspy uses to display and analyze vehicle activity.
How Plaspy Detects the Protocol
Plaspy accepts incoming device reports on a shared endpoint and automatically determines the correct protocol for supported trackers, including the FM-Tco4 HCV. This automatic detection means most users do not need to select a protocol inside Plaspy when the device is configured to report to the Plaspy endpoint.
- Plaspy listens on the shared server endpoint d.plaspy.com as well as the known server IP 54.85.159.138.
- The platform uses a single port for all devices, simplifying device configuration for fleets.
- Devices may be configured to send data over UDP or TCP depending on device capabilities and local settings.
- When a properly configured FM-Tco4 HCV reports to Plaspy, the platform matches the incoming data to the appropriate handling logic automatically.
- Users typically only need to ensure the device points to the Plaspy endpoint and uses the supported transport and port.
Transport and Connection Context
Connection context is about how the device reaches the Plaspy service rather than the internal message layout. For practical setup, configure network and transport so the FM-Tco4 HCV can reliably reach Plaspy servers on the standard Plaspy port.
- Devices may be configured to use either UDP or TCP on port 8888 depending on device support and site requirements.
- Plaspy accepts connections addressed to d.plaspy.com as well as the public server IP 54.85.159.138 on the shared port.
- All devices in Plaspy use the same port, so firewall rules and NAT mappings can be simplified across a fleet.
- Transport selection (UDP vs TCP) affects delivery characteristics but not the fact that the device reports to the Plaspy endpoint and port.
- Ensure network firewalls and mobile APN settings permit outbound traffic to the Plaspy server on port 8888.
Protocol Compatibility Notes
- Firmware versions may add, change, or remove specific telemetry fields; confirm the firmware level on each FM-Tco4 HCV before assuming feature parity.
- Hardware revisions and optional accessory modules (for example temperature sensors or additional CAN interfaces) can affect which data fields are present.
- The device can use either UDP or TCP transport; choose the transport mode supported by your device configuration and mobile network.
- Manufacturer-side configuration tools or SMS commands can change reporting intervals, message content, and enabled interfaces; these are handled by device settings rather than the Plaspy server.
- Plaspy automatically detects the device protocol when the device reports to the shared endpoint, but device-side misconfiguration can prevent successful detection.
- Validate compatibility against the latest Ruptela documentation when planning large deployments or firmware upgrades.
Why Protocol Understanding Matters
Understanding how the FM-Tco4 HCV communicates with Plaspy helps with successful deployment, incident troubleshooting, and long term reliability. Knowing the limits of automatic detection and the role of transport settings reduces setup time and operational surprises.
- Speeds initial provisioning by ensuring devices are pointed to the correct Plaspy endpoint and port.
- Helps diagnose connection problems related to transport selection, firewall rules, or APN restrictions.
- Clarifies which vehicle and sensor data types you can expect based on firmware and accessory choices.
- Informs decisions about polling intervals, data volume, and mobile data usage when scaling a fleet.
- Supports safer firmware and configuration change management by setting expectations for behavioral changes.
Why Use Plaspy with This Protocol
Using the Ruptela FM-Tco4 HCV with Plaspy provides a convenient way to collect rich vehicle and sensor data in a single platform. Plaspy receives GPS, CANbus, tachograph, and accessory reports and presents them in a unified fleet view, helping operations teams monitor routes, driver behavior, asset conditions, and refrigerated cargo status.
