Daisy chain igadziriso yemagetsi uko akawanda maturusi akabatanidzwa mune mutsara fashoni, imwe mushure meimwe. Inonzi daisy cheni nekuti yakaita sengetani yemaruva inonzi daisy.
Cheni yedaisy inogona kushandiswa kune zvinangwa zvakawanda, sekubatanidza matauriro akawanda kune imwe amplifier, kubatanidza marambi akawanda kune imwe magetsi emagetsi, kana kubatanidza michina yakawanda kune imwe USB port.
Daisy Chaining: A Primer
Chii chinonzi Daisy Chaining?
Daisy chaining chirongwa che wiring umo michina yakawanda yakabatanidzwa mukutevedzana kana mumhete, yakafanana negomba remaruva edaisy. Daisy maketani anogona kushandiswa kune simba, analogi zviratidzo, dhijitari data, kana musanganiswa wezvose zvitatu.
Mhando dzeDaisy Chains
- Daisy maketani anogona kushandiswa kubatanidza michina mikuru, senge nhevedzano yemagetsi mitsetse, kugadzira mutsara mumwechete murefu.
- Daisy maketani anogona zvakare kushandiswa kubatanidza zvishandiso mukati memudziyo, senge USB, FireWire, Thunderbolt, uye Ethernet tambo.
- Daisy maketani anogonawo kushandiswa kubatanidza zviratidzo zveanalogi, sebhazi remagetsi.
- Daisy maketani anogona zvakare kushandiswa kubatanidza masaini edhijitari, akadai seSeri Peripheral Interface Bus (SPI) IC.
- Daisy maketani anogona zvakare kushandiswa kubatanidza MIDI zvishandiso.
- Daisy maketani anogona zvakare kushandiswa kubatanidza JTAG akasanganiswa maseketi.
- Daisy maketani anogona zvakare kushandiswa kubatanidza Thunderbolt zvishandiso, senge RAID arrays uye komputa monitors.
- Daisy cheni inogona zvakare kushandiswa kubatanidza Hexbus zvishandiso, senge TI-99/4A, CC-40, uye TI-74.
Zvakanakira Daisy Chaining
Daisy chaining inogona kuve nzira yakanaka yekubatanidza akawanda maturusi nekuita kushoma. Iyo zvakare inodhura-inoshanda nzira yekubatanidza midziyo, sezvo ichida mashoma tambo uye maconnectors pane mamwe ma wiring scheme. Pamusoro pezvo, daisy chaining inogona kubatsira kudzikisa clutter, sezvo ichibvisa kudiwa kwetambo dzakawanda uye zvinobatanidza. Chekupedzisira, daisy chaining inogona kubatsira kuderedza kurasikirwa kwechiratidzo, sezvo chiratidzo chinoitwa patsva nechero mudziyo mucheni.
Signal Transmission: A Quick Guide
Analog Signals
Kana zvasvika kune zviratidzo zveanalog, kubatana kunowanzova nyore bhazi remagetsi. Uye kana iwe uchibata neketani yezvishandiso zvakawanda, iwe unozofanirwa kushandisa imwechete kana anopfuura anodzokorora kana amplifiers kurwisa attenuation.
Digital Signals
Dhijitari masiginecha pakati pemidziyo inogona zvakare kufamba mubhazi remagetsi riri nyore. Muchiitiko ichi, iwe uchada bhazi terminator pane yekupedzisira mudziyo mucheni. Kusiyana nemasaini eanalogi, masaini edhijitari anogona kuvandudzwa nemagetsi (asi asina kuchinjwa) nechero mudziyo mucheni.
Mazano eKufambiswa Kwemasaini
Heano mashoma matipi ekuti urambe uchifunga kana uchibata nechiratidzo chekufambisa:
- Shandisa anodzokorora kana maamplifiers kurwisa attenuation mumasaini eanalog.
- Shandisa chiteshi chebhazi pane yekupedzisira mudziyo mucheni kune masaini edhijitari.
- Dhijitari masiginecha anogona kuvandudzwa nemagetsi (asi asina kuchinjwa) nechero mudziyo mucheni.
- Usakanganwa kutarisa Passthrough kuti uwane rumwe ruzivo.

Daisy chaining computing zvikamu ndeimwe nzira huru yekubatanidza akawanda maficha. Zvinosanganisira kubatanidza masesisheni akawanda pamwechete, kubvumira vashandisi kuwana akawanda masisitimu kamwechete. Izvi zvinonyanya kubatsira kune mabasa anoda kuwana akawanda masisitimu.
Daisy-Chained vs. Pigtailed Parallel-Wired Receptacles
Chii Musiyano?
Kana zvasvika kune wiring midziyo yemagetsi, kune nzira mbiri huru: daisy-chaining uye parallel wiring. Ngatitarisei kusiyana kwezviviri izvi:
- Daisy-chaining (kana wiring "in-series") zvinoreva kubatanidza zvigadziro zvese "kumagumo kusvika kumagumo" uye kushandisa peya dzematerminal pamudziyo wega wega kutakura ikozvino kubva kune imwe mudziyo kuenda kune inotevera. Kana chero chinongedzo kana chishandiso chiri munhevedzano chikavhiringidzwa, midziyo yakadzika kubva ipapo inopera simba.
- Parallel wiring zvinoreva kubatanidza zvigadziro munzira dzakawanda, kuitira kuti kana chimwe chezvigadziro chikatadza, zvimwe zvigadziro padunhu zvinoramba zvisina kukanganiswa. Muchikamu chakafanana, kuyerera kwezvino kwakakamurwa, saka chikamu chayo chete chinoyerera nemuchina wega wega.
