EV - EV-601 Protocol

This page describes the public protocol context for using the EV EV-601 tracker with Plaspy. It focuses on how the device communicates with Plaspy at a high level and what to expect when integrating the tracker for vehicle and motorcycle monitoring. The EV-601 is a versatile tracker offering real-time web tracking, SMS reporting, GSM GPRS connectivity, onboard storage, geo-fencing, alarms, remote immobilization, and OTA firmware updates, and these capabilities translate into the kinds of messages and events your tracking platform will receive.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when a device reports to the Plaspy endpoint. Exact protocol behavior can vary by firmware version, hardware revision, and manufacturer implementation, so while Plaspy accepts connections from EV-601 devices, specific command availability and message details may differ between units and firmware releases. For network setup, Plaspy listens on d.plaspy.com and the public server IP 54.85.159.138 on port 8888, and devices may be configured to use either UDP or TCP on that same port.

Protocol Overview​

At a high level the EV-601 communication protocol governs how the tracker reports position, events, and status to a remote server and how remote commands are delivered. The protocol provides the structure and timing for transmitting GPS fixes, alerts, and input or output state changes so Plaspy can present accurate location and event data to users.

  • Enables the EV-601 to send location updates, movement alerts, and status reports to a remote endpoint for processing by Plaspy
  • Carries event information such as geo fence triggers, SOS alarms, power loss, and input changes that Plaspy interprets as actionable alerts
  • Allows remote commands for features the device exposes, including immobilization or output control, subject to the device firmware and configuration
  • Supports SMS and GPRS based reporting methods on the device side while using IP transport to reach Plaspy when data connectivity is available
  • Works with the device memory and reporting options to ensure data is delivered or buffered when connectivity is intermittent

How Plaspy Detects the Protocol​

Plaspy accepts incoming connections on a single shared endpoint and port and determines the appropriate tracker protocol automatically when a device reports. In most cases you will not need to choose a protocol manually in Plaspy if the EV-601 is configured to report to the Plaspy server.

  • Plaspy listens on the domain d.plaspy.com and the server IP 54.85.159.138 for device connections
  • All devices that report to Plaspy use the same port so a single configuration can cover many models
  • Plaspy automatically detects the tracker protocol when a properly configured EV-601 initiates communication
  • Users typically configure the EV-601 to point to Plaspy and do not need to select a protocol inside Plaspy for basic reporting
  • If a device behaves differently because of firmware or regional settings, consult manufacturer documentation and device logs to confirm reporting configuration

Transport and Connection Context​

The EV-601 can be configured to use IP transport over the mobile network to send data to a remote server. When connected to Plaspy, the transport and destination settings determine how the device reaches the Plaspy endpoint.

  • The device may be configured using UDP or TCP on port 8888 depending on device support and settings
  • Plaspy accepts device connections to d.plaspy.com or directly to 54.85.159.138 on port 8888
  • All devices in Plaspy use the same port which simplifies server side configuration and device setup
  • Choose UDP or TCP on the device according to the tracker firmware guidance and the network behavior you need
  • If cellular connectivity is intermittent the tracker may buffer data in device memory before sending when the link is available

Protocol Compatibility Notes​

  • Firmware differences can change available commands, reporting intervals, and message content even within the same EV-601 model
  • Hardware revisions or optional accessories may add or remove I O channels and event types that the protocol will convey
  • Manufacturer region firmware may enable localized features or different default transport settings
  • Transport selection between UDP and TCP affects delivery characteristics and should match how the device was provisioned
  • Verify that the EV-601 is configured to report to d.plaspy.com or 54.85.159.138 on port 8888 to reach Plaspy
  • Always confirm compatibility details against the latest EV documentation and release notes before large scale deployment

Why Protocol Understanding Matters​

Understanding the EV-601 communication protocol at a practical level helps ensure a smooth setup, reliable reporting, and effective troubleshooting when using Plaspy. Knowing what the device sends and how it connects reduces integration friction and improves operational outcomes.

  • Helps verify that the device is pointed to the correct Plaspy endpoint and port for successful communication
  • Enables faster diagnosis of missing or malformed messages that might be caused by firmware differences or transport mismatches
  • Guides decisions about UDP versus TCP based on desired delivery behavior and device configuration options
  • Clarifies which device events and alarms should appear in Plaspy and which may require additional device configuration
  • Supports planning for OTA firmware updates and the potential for behavior changes after updates

Why Use Plaspy with This Protocol​

Using the EV-601 with Plaspy gives organizations a practical way to collect vehicle and motorcycle location, status, and event information in a single platform. Plaspy presents live location updates, alerts, and historical data while Plaspy s shared port and automatic protocol detection simplify onboarding across many device models.
