Tytan SAT - DS520 Protocol
This page documents the public protocol context for using the Tytan SAT DS520 tracker with Plaspy. It focuses on how the device communicates with the Plaspy endpoint, what connection choices are commonly used, and what to check when integrating the DS520 for real time tracking and telemetry. The goal is to provide clear, non sensitive protocol context that helps with setup and troubleshooting while pointing users to manufacturer resources for firmware specific details.
Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when a device reports to the platform. Exact protocol behavior can vary with firmware revisions, hardware variants, and manufacturer configuration options, so this page presents general guidance rather than firmware specific command descriptions.
Protocol Overview
The DS520 uses standard cellular data to report GPS and GLONASS positions, speed, and events from its inputs and sensors to a remote server. Its communication protocol defines how the device formats and sends telemetry and event records so a backend like Plaspy can ingest and interpret the data for tracking and monitoring.
- The protocol enables periodic and event driven position reports that include location, speed, and status changes.
- It conveys sensor and input states from analogue and digital channels as configured on the device.
- Non volatile local storage ensures recorded records are retransmitted to the server after connectivity is restored.
- Transport choices such as UDP or TCP determine how packets are delivered to the server endpoint.
- Proper configuration of the server address and transport is required for reliable reporting to Plaspy.
How Plaspy Detects the Protocol
Plaspy operates a unified public endpoint for device reporting and uses automatic detection to identify the tracker protocol when data arrives. For most DS520 deployments, this means minimal manual protocol selection is required inside the platform once the device is pointed at the Plaspy endpoint.
- Plaspy server domain is d.plaspy.com which resolves to the Plaspy reporting endpoint.
- Plaspy server IP is 54.85.159.138 which can be used where DNS is not available.
- The port is 8888 and Plaspy uses the same port for all supported devices.
- The device may be configured using UDP or TCP on port 8888 depending on device support and site requirements.
- Plaspy automatically detects the tracker protocol when a device reports to the endpoint so manual protocol selection is typically not necessary.
Transport and Connection Context
The DS520 supports reporting over cellular data and can be configured to send telemetry to a Plaspy endpoint using either UDP or TCP. Choosing the transport mode and confirming the server address are the primary connection steps required to get the device to report to Plaspy.
- Devices may point to d.plaspy.com or directly to 54.85.159.138 as the server address.
- The device may be configured to use UDP or TCP on port 8888 according to installation needs.
- All devices in Plaspy use the same port which simplifies device configuration for mixed fleets.
- For intermittent coverage, enable the DS520 local storage features so data is buffered and retransmitted when connection resumes.
- Verify APN and SIM data connectivity as part of the connection checklist.
Protocol Compatibility Notes
- Firmware revisions can change message timing, optional fields, and supported event types; confirm firmware level if behavior differs from expectations.
- Hardware revisions or optional I O modules on the DS520 may add or alter available inputs and sensor reporting.
- Transport selection between UDP and TCP can affect delivery guarantees and should match the device configuration on the tracker.
- Manufacturer side configuration options such as intervals, sleep modes, and event thresholds influence reporting frequency and battery use.
- Remote configuration and firmware update features may require additional server settings such as FTP access as supported by the device.
- Always validate any device specific parameters against official manufacturer documentation and the deployed firmware release.
Why Protocol Understanding Matters
Understanding the communication protocol helps ensure devices report consistently, alarms and sensor data are interpreted correctly, and long term operations remain reliable. Knowing what the tracker sends and how Plaspy receives it reduces setup time and avoids common integration mistakes.
- Helps confirm proper server and transport settings so the DS520 can reach d.plaspy.com or 54.85.159.138 on port 8888.
- Aids in troubleshooting missing telemetry, retransmission behavior, and event handling after connectivity interruptions.
- Clarifies how sensor and input data from analogue inputs, digital inputs, 1 wire sensors, and accelerometer events are expected by the backend.
- Supports planning for fleet wide configuration where all devices use the same Plaspy port and automatic protocol detection.
- Guides decisions about power saving modes and reporting intervals to balance battery use and reporting needs.
Why Use Plaspy with This Protocol
Using the DS520 with Plaspy provides organizations with centralized visibility into vehicle and asset location, sensor states, and event histories. Plaspy’s automatic protocol detection and unified endpoint reduce setup complexity for mixed fleets, while the DS520’s features such as multiple inputs, 1 wire support, and local storage make it versatile for many monitoring use cases.
