#Questo video descrive una riparazione che ho eseguito su una telecamera Dome
American Dynamics. La dome difettava nei dati, era visibile l'immagine in tempo reale ma non si muoveva nel brandeggio da tastiera, effettuando un analisi circuitale della scheda ho riscontrato che a difettare era il ricetrasmettitore di comunicazione RS-485/RS-422 sostituito il circuito integrato MAX491 la dome a ripreso a funzionare regolarmente. La dome in oggetto è oscurata per motivi di privacy by Gianluca Caldari

If the camera shows nesibaldo but this is changing controller 491 (RS422). If the camera does not work at all, of variable capacitors in the power chain.
