Nws paub zoo, hauv zej zog CAN tsawg kawg, tias txhua qhov CAN thiab CAN FD network yuav tsum raug txiav nrog 120 Ohm resistor ntawm txhua qhov kawg ntawm lub npav. … Yog tias koj qhov kev txiav tawm raug raug, koj yuav tsum nyeem kwv yees li 60 Ohms (ob lub 120 Ohm resistors nyob rau hauv parallel tsim ib tug tsis kam ntawm 60 Ohms).
CAN termination resistor?
A CAN Bus network yuav tsum muaj qhov cuam tshuam ntawm CAN High thiab CAN Low rau nws ua haujlwm kom raug. Rau qhov siab tshaj plaws ntawm qhov kev ncua deb, qhov kev txiav tawm zoo tshaj plaws yog ib 120 Ohm resistor ntawm txhua qhov kawg ntawmtsheb npav, tab sis qhov no tsis yog qhov tseem ceeb tshaj qhov kev ncua deb.
CAN termination resistor DB9?
CAN tsheb npav txiav tawm resistor - DB9 kiv puag ncig niam - ua-hauv 120 ohm - ValueCAN-Vector-ETAS tau tshaj. DB9 hloov chaw txuas, nrog CAN kawg interface, ib zaug molding xovxwm, khoom thiab txhim khu kev qha! A 120 ohm davhlau ya nyob twg resistor yog sib txuas ntawm tus pins 2 thiab 7 ntawm txiv neej thiab poj niam plugs.
Vim li cas kev txiav tawm resistor siv tau?
Terminal resistors xav tau hauv CAN tsheb npav vim CAN kev sib txuas lus yog ob txoj kev. Qhov kev txiav tawm ntawm txhua qhov kawg absorbs CAN teeb liab lub zog, kom ntseeg tau tias qhov no tsis cuam tshuam los ntawm cov cable xaus. Cov kev xav li no yuav ua rau muaj kev cuam tshuam thiab ua rau muaj kev puas tsuaj.
Kev sib txuas lus puas tuaj yeem txiav tawm?
Rau kev kub ceev / FD tuaj yeem, ob qho tib si kawg ntawm khub teeb liab xov(CAN_H thiab CAN_L) yuav tsum raug txiav. Qhov no yog vim kev sib txuas lus ntws ob txoj hauv kev ntawm CAN npav. CAN_L yog tus pin 2 thiab CAN_H yog tus pin 7 ntawm tus qauv 9-pin D-SUB connector. Qhov kev txiav tawm cov resistors ntawm ib lub cable yuav tsum phim lub nominal impedance ntawm cable.
