Kev ua kom txo tau RS485 kev sib txuas lus hauv tsheb npav
Cov tswv yim thiab tswv yim nram qab no yog muab los txo cov kev sib txuas lus.
1. Nws raug pom zoo tias cov neeg siv siv thiab yuav lub RS485 converter uas tau muab los ntawm qhov chaw tsim khoom siv los yog lub chaw tsim ua tus tsim hom ntu 485 converter.
2. Cov ntaub ntawv tswj xyuas kev lag luam yuav ua ntau qhov kev sim ua haujlwm nrog lawv txhawb RS485 hloov dua siab tshiab, thiab yuav kom tus neeg tsim khoom siv RS485 converter ua cov khoom muag thiab kev soj ntsuam raws li nws cov kev ua tsis tau zoo, yog li nws muaj kev sib haum xeeb zoo nrog cov khoom siv rau kev tswj. Tsis txhob sim mus yuav cheap RS485 converters.
3. Ua raws nraim li txoj cai ntawm RS485 tsheb tsim kev tsim kho rau kev tsim kho, muab xaus rau txhua lub sijhawm
.
4. Cov kev txhim kho scientific thiab pre-reserved yuav raug siv rau kev tsim tsheb npav RS485 nrog cov kab ntev thiab cov loads siab.
5. Yog qhov kev sib txuas lus ntev dhau lawm, xws li tshaj 500 meters, nws raug nquahu kom siv repeater lossis RS485HUB los daws teeb meem.
6. Yog tias lub tsheb thauj ntau dhau lawm, xws li tshaj li 30 zaus hauv npav, nws raug nquahu kom siv RS485HUB los daws qhov teeb meem.
7.Nyob-qhov chaw debugging theem ua ke debugging khoom. Nyob rau ntawm qhov chaw commissioning yuav tsum nqa ob peb keyboards uas yuav siv sij hawm ntev thiab ntau cov loads, feem ntau siv computer laptop, lub multimeter uas xeem Circuit Court breaker, thiab ntau 120 ohm terminating resistors.
