Quick answers

Does the AVL-921 work with Traxelio?

A public device list shows the GoPass AVL-921 on the T55 protocol, and Traxelio receives T55 on port 5005. Confirm your unit's full marking first, then ask Traxelio support to check the port and your IMEI before you change its server settings.

What server and port should an AVL-921 use?

The host is gps.traxelio.com and the port for T55 is 5005. We do not publish setup commands for this model, so enter these values with the setup sheet from your seller and ask Traxelio support if the sheet is unclear.

My AVL-921 shows no position after the change. What do I check?

Check that the SIM has data, the server is gps.traxelio.com, the port is 5005, the unit has a GPS fix outdoors, and the IMEI in Traxelio matches the label. If it stays silent, contact Traxelio support with the IMEI.

Overview

About the AVL-921

A public device list carries the GoPass AVL-921 on the T55 protocol. Traxelio receives T55 reports on port 5005 at gps.traxelio.com, so the unit can report to a Traxelio account once its server fields point there. This page does not publish setup commands, because no public setup sheet for this model is available to us: use the sheet that came from your seller, and ask Traxelio support to confirm the port and your IMEI before you switch. Read the full model marking and hardware revision on the unit first, since a public device list carries several GoPass AVL models under similar names. After the switch, add the IMEI in Traxelio and look for the first position outdoors with a SIM that has data.
