-
3
Do not wait for an ACK
NTO has no reply byte. A parsed ^NB line is enough.
-
4
Prove one NTO fix
Send one line whose letter is A on 5250 and verify a map point.
Still offline after GPS lock
Nto still not landing
- NTO aimed at the wrong port
NTO on 5250 is not NET on 5215 or MTX on 5083.
- Session up, empty map
The letter must be A. V and M bind the IMEI and will not plot.
- No ACK, assumed dead
This dialect has no reply byte. Check the map, not the socket for an ACK.
FAQ
Nto leftover questions
Does NTO send Concox 0x7878 frames?
No. NTO is ^NB, ASCII CSV. Concox families use 0x7878 binary login.
Which NTO letter plots a fix?
A plots. V and M will not plot.
What do NTO status bits mark?
Bit 1 is jamming. Later bits mark power-cut, overspeed, vibration, geofence enter/exit, low battery, and door.
Does NTO send an ACK?
No. There is no reply byte. A parsed ^NB line is the whole handshake.
Can an NTO unit run SMS setup or a controlled-action flow?
This dialect is positions only. There is no SMS family on this row.
