1
Capture a TeraTrack fingerprint
Confirm brace JSON with MDeviceID and IMEI, not an HR binary login and not packed ASCII 7E.

2
Point TeraTrack at 5239
Configure only TeraTrack to TCP 5239. TeraTrack on 5239 is not ThinkRace on 5098 or Tek on 5173.
-
3
Treat {01} as optional
Traxelio writes {01} only when MessageAck is 1. Silence is normal when that key is 0.
-
4
Prove one TeraTrack fix
Send one JSON object whose Latitude and Longitude parse on 5239 and verify a map point.
Still offline after GPS lock
Teratrack still not landing
- TeraTrack aimed at the wrong port
TeraTrack on 5239 is not ThinkRace on 5098 or Tek on 5173.
- Session up, empty map
The object must carry Latitude and Longitude as decimal strings. MDeviceID plus IMEI alone will not plot.
- No {01}, assumed dead
Traxelio writes {01} only when MessageAck is 1. Check the map, not the socket, when that key is 0.
FAQ
Teratrack leftover questions
Does TeraTrack send Concox 0x7878 frames?
No. TeraTrack is brace JSON with MDeviceID and IMEI. Concox families use 0x7878 binary login.
When does TeraTrack get a {01} reply?
Only when MessageAck is the string 1. Any other value gets no reply byte.
Which keys bind a TeraTrack unit?
MDeviceID and IMEI together. Either string can match the catalogue unit.
What does LockOpen 0 mean on TeraTrack?
LockOpen 0 is locked. LockOpen 1 is open. Traxelio stores that as the lock flag beside the fix.
Can a TeraTrack unit run SMS setup or a controlled-action flow?
This dialect is positions only. There is no SMS family on this row.
