Witam, proszę o pomoc w naprawie rejestratora CCTV. Urządzenie z uszkodzoną siecią LAN, w wyniku burzy uszkodzony został router, a razem z nim sieciówka rejestratora.

Układ LAN: MICREL KSZ8721BL

Za gniazdem LAN znajdują się 4 rezystory z opisem na obudowie: 85X, 3 mają oporność 75 Ohm, jeden miał 60 Ohm - podmieniony na 80 Ohm.

Filtr LAN to: DELTA LFE8505, po jego wtórnej stronie napięcia to ok. 2,5V.

Proszę o jakieś sugestie, sam micrel jest dostępny w sprzedaży natomiast nie widze nigdzie filtru.

Co do filterka, szukaj takiego w routerach albo switchach. Nowy jest dostępny w TME H1102NL co prawda zamiennik ale będzie działał. KSZ8721BL też mają. Jedne koszta przesyłki.

Wymiana scalaka i filtra rozwiązało problem.
