TTL VS Rs-232: Qhov sib txawv thiab cov nyiaj pab me me
Cov yam ntxwv hluav taws xob
TTL:
Kev Ntsuas Qib: 0V (Tsawg),+3.3 v / +5 v (siab)
Ib Leeg -} ended signaling
Luv luv nrug (feem ntau<1.5m)
Rs-232:
Cov qib voltage: {+3 v rau +15 v (qes), -3V rau -15v (siab)
Sib txawv kos npe
Ntev ntev (mus txog 15m)
Kho vajtse interface
TTL:
Siv cov gpio yooj yim (TX, rx, gnd)
Nqwm ntawm microcontrollers thiab sbcs
Rs-232:
Yuav tsum DB9 lossis DB25 Cov Qho
Xav Tau Kab Tsav Tsheb (piv txwv li, Max232)
Txhawb Nqa
A. TTL Support:
Feem ntau cov nus motherboards tsis muaj qhia txog TTL Headers
Hom rau:
Raspberry PI (GPIO Header)
Arduino laug cam
Beagone
Qhov chaw kho espp32 / esp8266666
Tuaj yeem nkag tau ntawm USB - ttl contrers (CP2102, Ch340G, FTDI)
B. Rs-232 txhawb nqa:
Motionsboards (Pre6-} 2010) feem ntau tau ua rau Rs-232 chaw nres nkoj
MotianBoard niaj hnub yuav suav nrog:
Dedicated com chaw nres nkoj (feem ntau db9)
Sab hauv header (feem ntau 9-tus lej)
USB - rau - rs232 adapter txhawb
Hom rau:
Industrial PCs
Cov neeg rau zaub mov Motherboards (SuperMICro, Asus Ws series)
Qee qhov siab -} kawg cov khw muag khoom (asus Pro series
Yuav ua li cas xyuas koj motherboard
Rau TTL:
Saib rau GPIO headers (feem ntau 2.54mm suab)
Kuaj xyuas cov lus qhia rau "Uart" lossis "lub sauv header"
Rau Rs-232:
Lub cev DB9 chaw nres nkoj (rov qab i / o vaj huam sib luag)
Sab Hauv Tsev (xyuas Motherboard Los Ntawm Txhais Tes)
Bios chaw yuav qhia cov chaw nres nkoj chaw nres nkoj
Kev ua haujlwm rau cov tshuab niaj hnub
TTL:
Siv USB - rau - ttl convers (dav muaj)
Rs-232:
Siv Pcie Serial Phaib lossis USB - rau - RS232 Adapters
Nco tseg:
Coob tus niaj hnub cov neeg tau txais kev pab cuam muaj Rs-232 kev txhawb nqa kom txuag tau qhov chaw, thaum TTL kev nkag tau cov neeg tshwj xeeb lossis cov khoom siv sab nraud. Kev lag luam thiab cov cav muaj feem ntau yuav suav nrog ob qho cuam tshuam ib txwm muaj.
Ua ntej -} chav kawm kws tshaj lij rau koj kom pom zoo cov kab nrog koj cov kev xav tau. Zoo meej tom qab {{2} Kev Muag Khoom Tso Siab Tsis Zam Koj Cov Kev Txhaum.
