Quick answers

Which protocol and port does GPS-103 use on Traxelio?

GPS103 ASCII on TCP port 5001. Send adminip123456 gps.traxelio.com 5001. Do not use tk103 port 5002, gt06 (5023), or Teltonika (5027).

What is the factory SMS password?

Coban manuals default to 123456. Change it after the first adminip. Traxelio's setup block lists copy-ready strings with that factory value.

Is TK103 the same as GPS-103 on Traxelio?

Hardware silkscreens often say both. Traxelio's GPS-103 page is the ASCII gps103 listener on 5001. The separate tk103 decoder listens on 5002 and will stay silent here.

How do I set APN and GPRS?

From the admin phone: apn123456 then gprs123456 (TCP). Then adminip123456 gps.traxelio.com 5001. begin123456 arms the unit.

Overview

About the GPS-103

The Coban GPS-103 (also sold as TK103 / GPS-103-A) is a hardwired 2G GNSS tracker with a cut-off relay, 12–24 V harness, and SMS command set. It reports the GPS103 ASCII dialect that Traxelio decodes on TCP port 5001. That is not the later TK103 decoder on port 5002. Send adminip123456 gps.traxelio.com 5001 after the APN, then Traxelio plots live map, geofences, and confirmed immobilizer cut after dashboard confirmation.

Common issues

Unit stays silent after adminip

Port must be 5001 for gps103. 5002 is the other Coban decoder. 9000/9001 are vendor-manual examples, not Traxelio. Match IMEI to the Traxelio device id.

SMS replies OK but no map

Send gprs123456 after APN so the unit leaves SMS-only mode. Confirm the SIM has data, not voice-only credit.

Parked car jumps around the block

Single-constellation GPS jitter. Use ignition plus GPS as the movement source. This is expected urban multipath, not a Traxelio map bug.

FAQ

Frequently Asked Questions

Common questions about using the GPS-103 with Traxelio

From the admin phone send apn123456 <carrier-apn>, then adminip123456 gps.traxelio.com 5001, then gprs123456. Factory password is 123456 unless you already changed it. Traxelio's setup block lists copy-ready strings. Do not send Teltonika setparam or GT06 SERVER,1 hashes to this unit.

This catalogue row is the GPS103 ASCII dialect on TCP 5001. Traxelio's tk103 decoder is a different listener on 5002. Silkscreens that print both names still need the matching port. If adminip to 5001 plots a fix, stay on this page.

Yes through the cut-off relay. Prefer stop123456 (cuts when speed is low) over quickstop123456. Traxelio sends the immobilizer command only after explicit dashboard confirmation. Resume with resume123456.

No. Coban SMS concatenates a six-digit password into the command (factory 123456). There is no separate four-digit PIN field.
