Phenomena e Tloaelehileng ea ho se sebetse ha Karete ea Taolo ea LED
Phenomenon 1: Kamora ho hokahanngoa le ho tsamaisoa, ke mananeo a mang feela a tla emisa ho bapala ebe o qala ho bapala hape.
Lebaka le ka sehloohong ke horephepelo ea motlakaseha e lekane mme karete ya taolo e iqalla hape.1. Fokotsa khanya;2. Motlakase o nang le karete ea ho laola o tla le mapolanka a mabeli a fokolang;3. Eketsa phepelo ea motlakase
Phenomenon 2: Ha karete ea taolo e tloaelehile, skrine ea pontšo ha e bontše kapa khanya e sa tloaeleha.
Kamora hore karete ea taolo e hokahane le mokhanni oa ponts'o 'me e buletsoe, ea kamehla ke likhakanyo tse 16.Haeba ho se na ponts'o, ka kopo sheba hore na polarity ea data le litlhophiso tsa polarity tsa OE ho software ea taolo li nepahetse;Haeba khanya e sa tloaeleha 'me ho na le mola o khanyang ka ho khetheha, ho bontša hore boemo ba OE bo khutliselitsoe morao.Ka kopo, seta OE ka nepo.
Phenomenon 3: Ha o fetisetsa tlhahisoleseling ho karete ea taolo, sistimi e khothaletsa "Phoso e etsahetse, phetisetso e hlolehile"
Ka kopo sheba hore na khokahanyo ea khokahanyo ea puisano e nepahetse, hore na jumper e kareteng ea taolo e qhomela boemong bo lumellanang le boemo, le hore na li-parameter tsa "Control Card Settings" li nepahetse.Hape, haeba motlakase o sebetsang o le tlase haholo, ka kopo sebelisa multimeter ho lekanya le ho netefatsa hore motlakase o ka holimo ho 4.5V.
Phenomenon 4: Kamora hore tlhahisoleseling e kenngoe, skrine ea ponts'o e ke ke ea bonts'a ka mokhoa o tloaelehileng
Sheba hore na khetho ea tlhahiso ea scan "Control Card Settings" e nepahetse.
Ketsahalo ea 5: Puisano ha e bonolo nakong ea 485 marang-rang
Ka kopo sheba hore na mokhoa oa ho hokahanya oa mohala oa puisano o nepahetse.U se ke ua hokahanya mela ea puisano ea skrine ka 'ngoe hammoho le khokahanyo ea k'homphieutha ka phoso, kaha sena se tla hlahisa maqhubu a matla a bonahatsang le ho baka tšitiso e tebileng ho pontšo ea phetisetso.Mokhoa o nepahetseng oa ho hokahanya o lokela ho amoheloa, joalo ka ha ho hlalositsoe ho "Communication Interface Use and Precautions".
U ka rarolla tšubuhlellano ea puisano joang ha u sebelisa phetiso ea data ea GSM le ho daela hole?
U ka rarolla tšubuhlellano ea puisano joang ha u sebelisa phetiso ea data ea GSM le ho daela hole?Taba ea pele, hlahloba hore na ho na le bothata ka MODEM.Hakolla MODEM e hoketsoeng kareteng ea taolo ebe o e hokela komporong e 'ngoe.Ka tsela ena, li-MODEM tse romellang le tse amohelang li hokahantsoe le komporo mme li khaotsoe ho sistimi ea taolo.Khoasolla software e bitsoang "Serial Port Debugging Assistant" marang-rang, 'me u e sebelise ho theha le ho lokisa MODEM kamora ho e kenya.Taba ea pele, seta MODEM ea pheletso ea ho amohela ho karabelo ea othomathiki.Mokhoa oa ho hlophisa ke ho bula mothusi oa serial debugging lipheletsong ka bobeli, ebe o kenya "ATS0=1 Enter" ho mothusi oa serial debugging oa pheletso e amohelang.Taelo ena e ka seta MODEM ea pheletso ea ho amohela ho karabelo ea othomathiki.Haeba tlhophiso e atlehile, lebone la letšoao la AA ho MODEM le tla khantša.Haeba e sa bonesoa, tlhophiso ha e atlehe.Ka kopo, hlahloba hore na khokahano lipakeng tsa MODEM le komporo e nepahetse le hore na MODEM e buletsoe.
Kamora hore litlhophiso tsa karabo ea othomathike li atlehe, kenya "Nomoro ea Mohala ea Moamoheli, Kena" ho mothusi oa serial port debugging qetellong ea ho romella, ebe o letsetsa pheletso e amohelang.Ka nako ena, tlhahisoleseling e 'ngoe e ka fetisoa ho tloha pheletsong ea ho romella ho ea pheletsong e amohelang, kapa ho tloha pheletsong e amohelang ho isa pheletsong ea ho romella.Haeba tlhahisoleseding e fumanweng ka mahlakoreng ka bobedi e tlwaelehile, kgokelo ya dikgokahano e se e thehilwe, mme lebone la sesupo sa CD ho MODEM le butswe.Haeba mekhoa eohle e ka holimo e tloaelehile, e bontša hore puisano ea MODEM e tloaelehile 'me ha ho na mathata.
Ka mor'a ho hlahloba MODEM ntle le mathata leha e le afe, haeba puisano e ntse e koetsoe, bothata bo ka 'na ba bakoa ke litlhophiso tsa karete ea taolo.Hokela MODEM ho karete ea ho laola, bula software ea litlhophiso tsa karete ea taolo qetellong ea ho romella, tobetsa ho Bala Back Settings, hlahloba hore na serial port baud rate, serial port, protocol, le li-setting tse ling li nepahetse, ebe u tobetsa Ngola Litlhophiso ka mor'a ho etsa. liphetoho.Bula software ea Offline King, beha sebopeho sa puisano se lumellanang le li-parameter ka mokhoa oa puisano, 'me qetellong u fetise sengoloa.
