Nrog rau COM ua pab pawg ua haujlwm, koj tuaj yeem simulation "ntau ceg" qauv ntawm cov khoom siv ua ke los ntawm Ethernet TCP \/ IP raws tu qauv. Los ntawm COM koom nrog Grouping, koj tuaj yeem tsim pawg com txhawb pab pawg thiab cov ntaub ntawv hloov pauv ntawm pawg rau ntau lub chaw ua lag luam ntawm NPOte ntawm NPPort Server Server. Nws tuaj yeem xa tib qho lus txib rau txhua pawg ntawm cov serial cov khoom siv los ntawm ethernet ntawm tib lub sijhawm, koj tuaj yeem ua haujlwm ib qho comortion rau kev tswj hwm ntau lub cev chaw nres nkoj tib lub sijhawm.
Tsim Ib Pawg
Ua raws li cov kauj ruam no ntxiv rau ntau qhov COM ports rau ib pawg (txog 32 C com ports ib pawg):
1. Thawj zaug tshawb rau lub cuab tam Napport uas yuav tsum tau ua pawg rau hauv com
2. Daim Ntawv Qhia COM COM
3. Xaiv cov ntawv sau ua ke ua rau cov pab pawg yuav tsum tau tsim, tom qab ntawd txoj cai-nias thiab xaiv cov chaw.
4. Xaiv ib tus lej com tus lej rau com pawg com pawg. (Koj tuaj yeem xaiv cov lej tsis siv, xws li com7, thiab lwm yam.
5. Xaiv cov "pawg xaiv chaw nres nkoj ua ke" Khwv thiab nyem OK.
6. Nyob rau "COM Grouping" nplooj ntawv, koj tuaj yeem tsim "sau" chaw nres nkoj los tswj cov ntaub ntawv sib kis (piv txwv li, DTR \/ RTS). Koj tuaj yeem muab chaw nres nkoj uas nws lub teeb liab yuav txiav txim siab los ntawm cov koom tes.
7. Nyem "OK" thiab paub meej tias qhov chaw nres nkoj serial. Lub comport port tshaj tawm tias cov chaw nres nkoj xaiv tau cim ua ib feem ntawm "pawg". Koj yuav muaj peev xwm saib cov chaw nres nkoj uas tau muab rau thiab tshem tawm los ntawm pawg. Nyem "Thov" mus siv cov chaw thiab thaum kawg nyem "Yog".
COM Ua Goleing Function Test
Qhib Kev Sib Tw Ua Si hauv Group hauv Group1 tuaj yeem sib txuas lus nrog Ethernet khoom siv. Qhov no tso cai rau ib tus com port xa tib qho lus txib rau ib pab pawg ntawm cov chaw nres nkoj ntawm cov ethernet.
Thov nco ntsoov tias tsuas yog chaw nres nkoj serial tuaj yeem qhib rau kev sib txuas lus hauv ib pawg com. Yog tias koj qhib lwm cov chaw nres nkoj hauv cov pab pawg, nws yuav ua kom sai "ntawm COM chaw nres nkoj tau nyob".
