Iinkqubo zokuSebenza kweSoftwe

I-Hardware Connection Diagram

UQhagamshelwano lweSoftware

Qinisekisa uqhagamshelo lwehardware, vula isoftware yeLedOK Express, kwaye ikhadi lokuthumela linokubonwa ngokuzenzekelayo kujongano lolawulo lwesixhobo. Ukuba ikhadi lokuthumela alinakubonwa, nceda ucofe iqhosha lokuhlaziya kwicala lasekunene lojongano lwesoftware. Ukuba iqhagamshelwe ngentambo yenethiwekhi, nceda uvule "iCable ye-RJ45 eqhagamshelwe ngokuthe ngqo" kwikona esezantsi ekhohlo yojongano lwesoftware.

Iiparamitha zeNkqubo yeLedOK

Ububanzi besikrini esigcweleyo se-LED kunye nesetingi zobude
Cofa kulawulo lweTheminali kwaye ukhethe isilawuli, yiya kwiiparamitha eziphambili kunye negama lokugqitha 888 ukufaka ujongano lokuseta.

Kwi-interface yoqwalaselo oluphezulu, faka ububanzi besikrini se-LED kunye neeparamitha zobude kwaye ucofe u-“Seta” ukwenza impumelelo.

Inethiwekhi yoqwalaselo yeLedOK 

Kukho iindlela ezintathu zekhadi lolawulo lokufikelela kwinethiwekhi, ezizezi, ukufikelela kwintambo yenethiwekhi, ukufikelela kwi-WiFi, ukufikelela kwinethiwekhi ye-3G / 4G, kunye neentlobo ezahlukeneyo zamakhadi okulawula unokukhetha indlela yokufikelela kwinethiwekhi ngokwesicelo (khetha enye yezi zintathu ).
Indlela yoku-1: Ukucwangciswa kwenethiwekhi yeentambo
Emva koko vula i-interface yokucwangciswa kwenethiwekhi, eyokuqala yinethiwekhi enentambo, unokuseta iiparamitha ze-IP zekhadi lokulawula elikhethiweyo.

Lawula ikhadi lokufikelela kwinethiwekhi yocingo oluphambili.
Xa ukhetha i-WiFi engenazintambo okanye i-4G yokufikelela kwinethiwekhi, inethiwekhi enentambo kufuneka ikhutshwe, kwaye idilesi ye-IP yekhadi lokuthumela ifunyenwe ngokuzenzekelayo.

Indlela yesi-2: I-WiFi ivuliwe
Jonga i-WiFi Vumela kwaye ulinde malunga nemizuzwana emi-3, cofa i-Scan WiFi ukuskena i-WiFi ekhoyo kufutshane, khetha i-WiFi kwaye ufake igama eligqithisiweyo, cofa Gcina ukugcina uqwalaselo lweWiFi kwikhadi lolawulo.

Emva kwemizuzu engama-3, ikhadi lokulawula liya kukhangela ngokuzenzekelayo i-WiFi hotspot eqhagamshelwe kwi-configuration, kwaye ukukhanya "kwe-intanethi" kwikhadi lokulawula kuya kukhanya ngokufanayo kunye nokucotha, kubonisa ukuba ixhumeke kwi-platform yefu. Ngeli xesha, ungangena kwiqonga lelifu www.m2mled.net ukuthumela inkqubo.
Iingcebiso
Ukuba i-WiFi ayikwazi ukungena kwi-intanethi, unokucombulula ezi meko zilandelayo:

1. Khangela ukuba i-eriyali ye-WiFi iqinisiwe;
2. Nceda khangela ukuba igama lokugqithisa le-WiFi lichanekile;
3. Khangela ukuba inani leetheminali zokufikelela kwi-router lifikelele kumda ophezulu;
4. Nokuba ikhowudi ye-E-khadi ikwindawo ye-wifi;
5. Khetha kwakhona i-WiFi hotspot ukulungisa uqhagamshelwano;
6. Ngaba uthotho lwenethiwekhi ye-Y/M eneentambo ezikhutshiweyo (inethiwekhi eneentambo eziphambili).

Indlela ye-3: uqwalaselo lwe-4G
Khangela Yenza i-4G isebenze, ikhowudi yelizwe i-MMC inokudityaniswa ngokuzenzekelayo yi-Get Status iqhosha, uze ukhethe "Umqhubi" ukufumana ulwazi oluhambelanayo lwe-APN, ukuba umqhubi akafumaneki, unokujonga ibhokisi yokukhangela "Custom", Emva koko faka ngesandla. ulwazi APN.

Emva kokumisela iiparamitha ze-4G, linda malunga nemizuzu ye-5 ukuba ikhadi lokulawula licofe ngokuzenzekelayo inethiwekhi ye-3G / 4G ukufikelela kwinethiwekhi; jonga ukukhanya "kwe-intanethi" yekhadi lokulawula elidanyazayo ngokufanayo kwaye kancinci, oku kuthetha ukuba iqonga lelifu liqhagamshelwe, kwaye ungangena kwiqonga lelifu ngeli xesha. www.ledaips.com ukuthumela iinkqubo.

Iingcebiso
Ukuba i-4G ayikwazi ukungena kwi-intanethi, unokujonga ezi meko zilandelayo:

1. Jonga ukuba i4Gantenna iqinisiwe;
2. Ngaba i-Y series enentambo yothungelwano ikhutshiwe (inethiwekhi eneentambo eziphambili);
3. Jonga ukuba ngaba i-APN ichanekile (ungadibana nomsebenzisi);
4. Ingaba imeko yekhadi lokulawula iyinto eqhelekileyo, kwaye ingaba ukuhamba okukhoyo kwekhadi lokulawula kwinyanga yangoku kukhulu kune-0M;
5. Khangela ukuba amandla omqondiso we-4G angaphezulu kwe-13, kwaye amandla omqondiso we-3G / 4G angafunyanwa ngokuthi "Ukufumanisa isimo seNethiwekhi".

Irejista yePlatform ye-AIPS

Ukubhaliswa kweakhawunti yeqonga lelifu
Vula i-interface yokungena kwi-platform yefu, nqakraza iqhosha lokubhalisa, igalelo lolwazi ngokweengcebiso ezifanelekileyo kwaye ucofe ukungenisa. Emva kokufumana i-imeyile yokuqinisekisa, cofa ikhonkco ukuze uqinisekise kwaye ugqibezele ubhaliso.

Ukubophelela kweakhawunti yeqonga lelifu
Ngena i web idilesi yeseva kunye ne-ID yenkampani kwaye ucofe Gcina. Idilesi yeseva yangaphandle yile: www.ledaips.com

Iphepha lokugqibela

Ngolwazi oluthe kratya malunga nesisombululo solawulo lweqela le-Intanethi lolawulo lwezixhobo zentengiso ye-LED, kunye namaxwebhu ahambelana nemiyalelo, nceda undwendwele webindawo: www.ledok.cn ngolwazi oluneenkcukacha. Ukuba kuyimfuneko, inkonzo yabathengi be-intanethi iya kunxibelelana nawe ngexesha. Amava kushishino ngokuqinisekileyo uya kukunika impendulo eyanelisayo, Shanghai Xixun ngokunyanisekileyo ujonge phambili kwintsebenziswano elandelayo nawe.

Ingxelo yeFCC

Naluphi na uTshintsho okanye uhlengahlengiso olungavunywanga ngokucacileyo liqela elinoxanduva lokuthotyelwa lunokuphelisa igunya lomsebenzisi lokusebenzisa isixhobo.
Esi sixhobo sithobela inxalenye ye-15 yeMithetho yeFCC. Umsebenzi uxhomekeke kwezi meko zimbini zilandelayo:

1. Esi sixhobo asinakubanga uphazamiseko oluyingozi, kunye
2. Esi sixhobo kufuneka samkele naluphi na uphazamiseko olufunyenweyo, kubandakanywa uphazamiseko olunokubangela ukusebenza okungafunekiyo.

INkcazelo yokuVela kwiMitha yeFCC:
Esi sixhobo sithobela imida yokuvezwa kwemitha yeFCC emiselwe indawo engalawulekiyo . Esi sixhobo kufuneka sifakwe kwaye sisebenze kumgama ongaphantsi kwama-20cm phakathi kweradiyetha nomzimba wakho.
Esi sixhobo sivavanyiwe saza safunyanwa ukuba sithobela imida yesixhobo sedijithali soDidi B, ngokungqinelana nenxalenye ye-15 yeMithetho yeFCC. Le mida yenzelwe ukubonelela ngokhuseleko olufanelekileyo ekuphazamisekeni okunobungozi kwindawo yokuhlala. Esi sixhobo sivelisa, sisebenzise kwaye sinokusasaza amandla amaza erediyo kwaye, ukuba asifakanga kwaye sisetyenziswe ngokuhambelana nemiyalelo, sinokubangela uphazamiseko oluyingozi kunxibelelwano lwerediyo. Nangona kunjalo, akukho siqinisekiso sokuba ukuphazamiseka akuyi kwenzeka kufakelo oluthile. Ukuba esi sixhobo sibangela uphazamiseko oluyingozi kunomathotholo okanye ulwamkelo lukamabonakude, olunokumiselwa ngokucinywa nokulayita isixhobo, umsebenzisi uyakhuthazwa ukuba azame ukulungisa uphazamiseko ngenye okanye ngaphezulu kwezi ndlela zilandelayo:

• Jongisa kwakhona okanye uhambise i-eriyali efumanayo.
• Yandisa ukwahlukana phakathi kwesixhobo kunye nomamkeli.
• Qhagamshela izixhobo kwindawo yokuphuma kwisekethe eyahlukileyo kuleyo apho umamkeli aqhagamshelwe khona.
• Dibana nomthengisi okanye igcisa likanomathotholo/kumabonakude ukuze ufumane uncedo.
