7.3 Opravy
V případě potřeby servisního zásahu kontaktujte technickou podporu společnosti 2N TELEKOMUNIKACE a.s. na e-mail: techsupport@2n.cz nebo tel.: (+420)900300300.
Opravy zařízení smí provádět pouze autorizované servisní středisko nebo přímo výrobce.
Pro diagnostiku potíží se zařízením lze využít error log. To je část paměti, kam se zapisují jednotlivé chyby, pokud jsou detekovány. Je možné odhalit problémy s připojením do WWAN sítě případně diagnostikovat příčiny odpojení terminálu od serveru a chyby komunikace v datovém kanálu WWAN modulu. Ovládá se pomocí následujícího příkazu.
at^scerr?
Vypíše stav chybového bufferu.
- ^SCERR: 72> 8,10
- ^SCERR: 73> 8,10
at^scerrclear
Smaže obsah chybového bufferu.
Tabulka chybových kódů
Tato tabulka popisuje význam SC reset chybových kódů. Informace jsou zobrazovány ve formátu:
^SCERR: {id}> {ID},{Additional value}
- id – sekvence čísel určující pořadí chyby od zapnutí zařízení
- ID – identifikace chyby
- Additional value – detailnější informace a popis situace
- počet zbývajících pokusů
- CME a CMS errory – dohledání je možné v data-sheetu modulu
- Command channel state – viz tabulka níže
- Data channel state – viz tabulka níže
- UPGRADE error code – viz tabulka níže
