Quelle version de poste peut être transformée ?
Indeed, there are several hardware versions of the ATD-868UV set. Only version 2 is compatible with this modification.
On the identification label on the back of the radio (under the battery), you will see FCC ID: T4KD868UV. But this indication is the same for all versions of the set. This does not allow to know if the terminal is compatible with the update. Similarly, the hardware version indicated in the Info menu is in any case indicated V1.10. The only way to be sure that this corresponds to a V2 device is to check the reference of the ARM processor.
The ATD878UV software uses about 750 kilobytes of memory. The ARM processor of the V2 version is a GD32F303VGT6 with a 1024 kilobyte flash memory. The GD32F303VET6 processor integrates only 512 kilobytes.
Nevertheless, the serial number printed on the back (S/NO) may be a good clue. But we do not know exactly the number from which the items are in version V2.
- 115011726901XXX : No – ARM VET6 with 512K
- 1150117317XXXX : Yes – ARM VGT6 with 1024K
- 150118069XXXX : Yes – ARM VGT6 with 1024K
The doubt can only be dispelled after opening the case and checking the serigraphy.
