ArkNav - K-18U Configuration

This page explains the public configuration context for using the ArkNav K-18U GPS Data Logger with Plaspy. It covers how the device's publicly described data output and vendor software are typically prepared for ingestion by a tracking platform and the practical server settings Plaspy requires for compatibility.

Plaspy uses shared server settings across supported devices and automatically detects the tracker protocol when data arrives. Exact manufacturer-side setup steps can vary by firmware, hardware revision, installation type, and vendor tools, so use this guide together with ArkNav documentation and vendor configuration utilities when preparing a K-18U for use with Plaspy.

Configuration Overview​

The goal of configuration is to make the K-18U's recorded GPS data available to Plaspy in a format the platform can ingest and display. Because the K-18U is primarily a GPS data logger that stores NMEA sentences, many integrations use the vendor software or a forwarding tool to transfer data into Plaspy rather than configuring a built in network stream on the device itself.

  • Prepare the device and stored NMEA files so a forwarder or vendor tool can read them
  • Configure any forwarding or network-capable middleware to target the Plaspy server endpoint
  • Select the transport protocol (UDP or TCP) if the forwarding tool or firmware requires it
  • Validate connectivity to Plaspy and confirm the platform is receiving records
  • Verify that the K-18U NMEA outputs are preserved or translated for Plaspy ingestion

Plaspy Server Settings​

When configuring the K-18U via a vendor tool, forwarder, or firmware that supports network transmission, use the following Plaspy server settings exactly as shown:

  • Server domain d.plaspy.com
  • Server IP 54.85.159.138
  • Port 8888
  • Transport support: UDP or TCP may be used depending on your tool or firmware
  • Plaspy automatically detects the tracker protocol when data is received

All devices in Plaspy use the same port, and Plaspy will attempt to detect the tracker protocol automatically from incoming data.

Typical Requirements Before Setup​

  • K-18U device charged and operational with a readable micro SD card containing recorded NMEA log files
  • USB cable or card reader and a PC with access to the K-18S Tracking Log Management Software or other vendor tools
  • Access to the official ArkNav documentation or configuration utilities for the K-18U
  • Network-capable forwarder, middleware, or firmware that can send data to the Plaspy server endpoint
  • Knowledge of the Plaspy server settings (d.plaspy.com, 54.85.159.138, port 8888) so they can be entered in the forwarding tool

How This Tracker Connects to Plaspy​

The K-18U records GPS NMEA sentences (for example GPRMC and GPGGA) to removable storage. To make that data available in Plaspy, recorded NMEA output must be forwarded or transmitted to the Plaspy server endpoint and port. When forwarding is in place, Plaspy will parse incoming data and make the device visible in the platform.

  • The device stores complete GPS NMEA sentences for later retrieval or processing
  • Vendor software such as K-18S or a third-party tool can read files from the micro SD and forward data
  • Forwarding tools or firmware should be configured to send data to d.plaspy.com or 54.85.159.138 on port 8888
  • Choose UDP or TCP transport in the forwarding tool if required; Plaspy supports both
  • Once data is received by Plaspy, the platform automatically detects the protocol and begins processing records so the device appears in the system

Common Configuration Workflow​

  1. Access the official manufacturer configuration method or software (for example K-18S Tracking Log Management Software) or your chosen forwarding middleware.
  2. Prepare the K-18U data files on the micro SD or connect the device to the vendor tool via USB.
  3. In the vendor tool or forwarder settings enter the Plaspy server domain d.plaspy.com or the server IP 54.85.159.138.
  4. Set the destination port to 8888 as required by Plaspy.
  5. If the tool requires a transport selection, choose UDP or TCP according to your network requirements.
  6. Apply or save the configuration in the vendor tool or forwarder and, if the device firmware requires it, restart the device or software to apply changes.
  7. Validate that the device or forwarder reports to Plaspy and that data appears in the platform.

Example Configuration Commands​

The ArkNav K-18U description provided here does not include manufacturer network commands for direct device-to-server configuration. Exact command syntax and availability can vary by firmware and vendor utilities. If you are using a forwarding tool or firmware that accepts command-line or SMS style commands, enter the Plaspy destination as:

  • Host: d.plaspy.com (or 54.85.159.138)
  • Port: 8888
  • Transport: UDP or TCP

Because the K-18U is commonly used as a data logger, many integrations will use the K-18S software or a custom forwarder to read NMEA files and send them to the Plaspy endpoint listed above. Confirm the exact command or configuration format in ArkNav documentation before applying settings.

Configuration Notes​

  • The K-18U stores full NMEA sentences which makes it straightforward to forward raw GPS strings, but you may need a converter to match Plaspy expected protocol formats when using middleware.
  • Firmware versions, vendor tools, and hardware revisions can change how or whether network transmission commands are supported; always check ArkNav documentation for your device revision.
  • When choosing between UDP and TCP, consider network reliability and latency; Plaspy supports either and will auto-detect the protocol.
  • All devices in Plaspy use the same port number 8888 for ingestion, so any forwarding configuration should target that port.
  • If your workflow uses periodic uploads rather than live streaming, ensure the forwarder timestamps and preserves chronological order so Plaspy accurately sequences events.

Why Use Plaspy with This Configuration​

Integrating the ArkNav K-18U with Plaspy gives organizations a practical path to convert recorded GPS NMEA logs into visibility inside a fleet tracking platform. Whether you forward live data from a network-capable forwarder or upload historic logs processed by vendor software, using the shared Plaspy endpoint simplifies destination configuration and lets Plaspy automatically handle protocol detection.
