Cellocator Protocol (MCGP binary TCP+UDP)
Cellocator on TCP and UDP 5033: MCGP, type 0 status or type 11 modular, type-4 ack, sum checksum.

1
Capture a Cellocator fingerprint
Confirm a frame that opens MCGP, not Carscop caret ASCII and not Castel @@.

Point Cellocator at 5033
Configure only Cellocator to TCP or UDP 5033. Cellocator on 5033 is not Carscop on 5040 or Castel on 5086.

Expect the type-4 ack
Most bodies are answered type 4. Type 11 is answered with a modular-ext ack whose inner module type is 9.

Prove one Cellocator fix
Send one type-0 status with lat/lon, or a type-11 body with GPS module 6, and verify a map point.
Still offline after GPS lock
Cellocator still not landing
- Cellocator aimed at the wrong port
Cellocator on 5033 is not Carscop on 5040 or Castel on 5086.
- Session up, empty map
Type 0 plots. Type 11 plots when GPS module 6 is present. Types 3, 7, 8, and 9 will not plot.
- No ack, assumed dead
Expect type 4. Type 11 expects a modular-ext ack. Check the map, not a Concox 0x7878 reply.
FAQ
Cellocator leftover questions
Does Cellocator send Concox 0x7878 frames?
No. Cellocator opens with MCGP then a type byte and a little-endian unique id. Concox families use 0x7878 binary login.
Which Cellocator types plot a fix?
Type 0 plots. Type 11 plots from modular GPS records. Types 3, 7, 8, and 9 are acknowledged and do not plot.
Does Cellocator send a reply?
Yes. Type 4 acknowledges most bodies. Type 11 is answered with a modular-ext ack whose inner module type is 9.
How are Cellocator coordinates scaled?
Default MCGP bodies convert radians. When the fourth header byte is not P, lat and lon are signed integers divided by 10 million.
Can a Cellocator unit run SMS setup or a controlled-action flow?
This dialect is positions only. Four catalogue devices are listed (CelloTrack 6M IP65, CelloTrack IP67, CelloTrack XT, Ekas Tracker). There is no SMS family on this row.
