Mercator II PC\/104-Plus-modulen integrerar fyra PCI-baserade 10\/100 Ethernet-portar med 24 anv\u00e4ndarkonfigurerbara digitala I\/O-linjer i det kompakta och robusta PC\/104-formatet. Denna 2-i-1-kombination av Ethernet och digitala I\/O-anslutningar kan bidra till att minska storleken och kostnaden f\u00f6r ditt inbyggda system genom att eliminera behovet av ett extra kort i din PC\/104-stack. <\/p>\n

Ethernet-portarna styrs av tv\u00e5 dubbla Micrel KSZ8842 Mac + Phy PCI-kontrollerchip, med tv\u00e5 portar per chip, och \u00e4r NE2000-kompatibla. Varje chip har en unik MAC-adress; d\u00e4rf\u00f6r \u00e4r endast tv\u00e5 Ethernet-portar synliga f\u00f6r slutanv\u00e4ndaren f\u00f6r aktiv kommunikation. De \u00f6vriga tv\u00e5 portarna fungerar som en switch f\u00f6r att m\u00f6jligg\u00f6ra kedjekoppling av n\u00e4tverk, d\u00e4r den ena porten p\u00e5 chipet fungerar som en uppl\u00e4nk till ett n\u00e4tverk medan den andra porten sk\u00f6ter den aktiva kommunikationen i n\u00e4tverket. <\/p>\n

De 24 digitala I\/O-ledningarna \u00e4r baserade p\u00e5 en 82C55-krets och har programmerbar riktning i grupper om 4 och 8 bitar. Alla I\/O-ledningar \u00e4r f\u00f6r enkelhetens skull utrustade med anv\u00e4ndarkonfigurerbara pull-up-motst\u00e5nd p\u00e5 10 k\u03a9. <\/p>\n

Tack vare det ut\u00f6kade temperaturomr\u00e5det (\u201340 \u00b0C till +85 \u00b0C) kan kortet anv\u00e4ndas i milj\u00f6er med extrema temperaturv\u00e4xlingar, till exempel i fordon eller utomhusinstallationer. Dessutom kan kortet anpassas med 0-ohmsmotst\u00e5nd ist\u00e4llet f\u00f6r jumperblock f\u00f6r \u00f6kad t\u00e5lighet i milj\u00f6er med starka vibrationer. <\/p>\n

Diamond Systems erbjuder l\u00e4mpliga anslutningskablar f\u00f6r att underl\u00e4tta f\u00f6r dig. Kabelnummer C-PRZ-02 har en RJ-45-kontakt f\u00f6r Ethernet som kan monteras p\u00e5 panelen, och kabelnummer C-26-18 \u00e4r en bandkabel med 26 ledare f\u00f6r digital I\/O. <\/p>\n","protected":false},"excerpt":{"rendered":"
