DSF21 GPS Tracker
The DSF21 reports to FleetStack over the DSF22 protocol on server port 5236. Point the tracker at your FleetStack host and that port, and its position and status messages decode straight into the platform.
Product Details
The DSF21 is listed in the FleetStack device catalogue as a DSF22-protocol tracker. Because FleetStack already runs a DSF22 decoder on port 5236, the DSF21 needs no custom integration work — set the tracker server host and port, set the SIM APN, and the device appears in live GPS tracking as soon as it sends its first position report.
FleetStack decodes 3 models on the DSF22 protocol, so a mixed fleet of DSF22 hardware shares a single port and one set of server settings, with no per-model configuration to maintain. The device port list carries the port for every protocol, and the GPS command list carries the SMS and GPRS commands used to point a tracker at a new server.
Once it is reporting, DSF21 telemetry drives geofencing, trip management, route management, driver behavior scoring, maintenance reminders and the alert center. The same data is available through the REST API if you are feeding it into your own systems, and FleetStack can be deployed as white-label GPS tracking software under your own brand.

Frequently Asked Questions
Which server port does the DSF21 use with FleetStack?
The DSF21 reports on port 5236, which is where the FleetStack DSF22 decoder listens. Your server host is issued with your account credentials. Ports for every supported protocol are listed on the device port list.
How do I connect the DSF21 to FleetStack?
Set the tracker server host to your FleetStack host and its port to 5236, then set the SIM APN for your network — usually over SMS configuration. The GPS command list carries the SMS and GPRS commands, the video tutorials cover the platform side, and technical support can help commission a device.
Which protocol does the DSF21 use?
The DSF21 uses the DSF22 protocol. FleetStack decodes 3 models on DSF22, so a mixed fleet of DSF22 hardware runs on one port and one set of server settings. Browse them all on supported devices.
What can I do with DSF21 data in FleetStack?
Position and status reports from the DSF21 drive live GPS tracking, geofencing, trip management, driver behavior scoring and the alert center — the same feature set every supported device shares.
Add the DSF21 to FleetStack
FleetStack already decodes the DSF22 protocol on port 5236, so the DSF21 can be onboarded without custom development. View pricing, book a demo to see the platform with your own hardware, or contact us for help with the device configuration.
