Yankho liyenera kukhala mu data, pambuyo posinthidwa bwino, byte yoyamba ndi chipangizo chatsopano
adilesi. Adilesi ya chipangizo ikasinthidwa, iyamba kugwira ntchito nthawi yomweyo. Panthawi imeneyi, wogwiritsa ntchito
iyenera kusintha lamulo lafunso la pulogalamuyo nthawi yomweyo.
Werengani ndi Kusintha Baud Rate
(1) Werengani mlingo wa baud
Chipangizo chokhazikika cha fakitale ya baud ndi 9600. Ngati mukufuna kusintha, mukhoza kusintha malinga ndi
tebulo lotsatirali ndi njira yolumikizirana yofananira. Za example, werengani chipangizo chamakono
baud rate ID, lamulo ndi: 01 03 00 67 00 01 35 D5, mawonekedwe ake amagawidwa motere.

ID ya chipangizo	ID ya ntchito	Adilesi Yoyambira	Kutalika Kwadongosolo	CRC16

Werengani ma encoding a baud rate pa chipangizo chomwe chilipo. Baud rate encoding: 1 ndi 2400; 2 ndi 4800; 3 ndi 9600; 4 ndi 19200; 5 ndi 38400; 6 ndi 115200.
Kuti mupeze lamulo lolondola, chipangizocho chidzayankha, mwachitsanzoample, data yoyankhira ndi 01 03 02 00 03 F8 45, mawonekedwe ake akuwonetsedwa patebulo lotsatirali:

ID ya chipangizo	ID ya ntchito	Kutalika Kwadongosolo	Mtengo ID	CRC16

zolembedwa molingana ndi kuchuluka kwa baud, 03 ndi 9600, mwachitsanzo, chipangizo chapano chili ndi chiwopsezo cha 9600.
(2)Sintha mlingo wa baud
Za example, kusintha mlingo wa baud kuchokera 9600 kuti 38400, mwachitsanzo kusintha kachidindo kuchokera 3 mpaka 5, lamulo ndi: 01 06 00 67 00 05 F8 1601 03 00 66 00 01 64 15.

ID ya chipangizo	ID ya ntchito	Adilesi Yoyambira	Target Baud Rate	CRC16
01	03	00 66	00 01	64 15

Sinthani mlingo wa baud kuchokera ku 9600 kupita ku 38400, kusintha kachidindo kuchokera ku 3 mpaka 5. Mlingo watsopano wa baud udzachitika nthawi yomweyo, pomwe chipangizocho chidzataya yankho lake ndipo mlingo wa baud wa chipangizocho uyenera kufunsidwa moyenerera. Zosinthidwa.
Werengani Mtengo Wowongolera
(1) Werengani Mtengo Wowongoleredwa
Pakakhala cholakwika pakati pa data ndi mulingo wolozera, titha kuchepetsa cholakwika chowonetsera posintha mtengo wowongolera. Kusiyana kowongolera kumatha kusinthidwa kukhala kuphatikiza kapena kuchotsera 1000, ndiye kuti, mtengo wamtengo wapatali ndi 0-1000 kapena 64535 -65535. Za example, pamene mtengo wowonetsera uli wochepa kwambiri, tikhoza kukonza mwa kuwonjezera 100. Lamulo ndi: 01 03 00 6B 00 01 F5 D6 . Mu lamulo la 100 ndi hex 0x64 Ngati mukufuna kuchepetsa, mukhoza kukhazikitsa mtengo woipa, monga -100, wolingana ndi mtengo wa hexadecimal wa FF 9C, womwe umawerengedwa ngati 100-65535 = 65435, ndikusinthidwa kukhala hexadecimal kuti 0x ndi 9C. Mtengo wowongolera umayambira pa 00 6B. Timatenga parameter yoyamba ngati example. Mtengo wowongolera umawerengedwa ndikusinthidwa chimodzimodzi kwa magawo angapo.

ID ya chipangizo	ID ya ntchito	Adilesi Yoyambira	Kutalika Kwadongosolo	CRC16
01	03	00 6b ndi	00 01	F5 D6

Kuti mupeze lamulo lolondola, chipangizocho chidzayankha, mwachitsanzoample, data yoyankhira ndi: 01 03 02 00 64 B9 AF, mawonekedwe ake akuwonetsedwa patebulo lotsatirali:

ID ya chipangizo	ID ya ntchito	Kutalika Kwadongosolo	Mtengo wa data	CRC16
01	03	02	00 64	B9 AF

Mu data yankho, byte yoyamba 01 imasonyeza adiresi yeniyeni ya chipangizo chamakono, ndipo 00 6B ndiye woyamba boma kuchuluka kuwongolera mtengo kaundula. Ngati chipangizocho chili ndi magawo angapo, magawo ena amagwira ntchito motere. Momwemonso, kutentha, chinyezi ndi chizindikiro ichi, kuwala nthawi zambiri kulibe chinthu ichi.
(2) Sinthani mtengo wowongolera
Za example, kuchuluka kwazomwe zikuchitika pano ndi kochepa kwambiri, tikufuna kuwonjezera 1 ku mtengo wake weniweni, ndipo mtengo wapano kuphatikiza 100 kuwongolera opareshoni lamulo ndi: 01 06 00 6B 00 64 F9 FD.

ID ya chipangizo	ID ya ntchito	Adilesi Yoyambira	Kopita	CRC16
01	06	00 6b ndi	00 64	F9 FD

Pambuyo pochita bwino, chipangizocho chidzabwezera zambiri: 01 06 00 6B 00 64 F9 FD, magawowa amayamba kugwira ntchito mwamsanga pambuyo posintha bwino.
