Cov Lus Qhia
Kauj ruam 1
Muab cov khoom sib hloov ua ke nrog koj tus kheej tes ntawm Max232 microcircuit, rau qhov no siv lub voj voog tsim nyog. Nco ntsoov tias koj muaj tag nrho cov khoom tsim nyog los tsim lub transceiver. Txiav txim siab rau qhov loj me ntawm lub rooj tsavxwm thiab txiav ib daig ntawm qhov yuav tsum muaj qhov loj me ntawm lub khob cij. Tom qab ntawd solder nws.
Kauj ruam 2
Solder lub capacitors, koj yuav tsum ua kom sov tsis pub ntev tshaj 7 vib nas this. Muag txhua tus dhia. Tom ntej no, npaj qhov chaw nres nkoj COM, rau qhov no, cam cov xov hlau mus rau qhov thib tsib thiab ob pins, ib qho xaim rau lub cev. Npaj lub USB: xov xov hluav taws xob rau thawj thiab plaub pins raws li daim duab, ib qho xaim rau rooj plaub. Muag txhua yam raws li lub tswvyim.
Kauj ruam 3
Sau cov transceor siv cov transistor. Siv cov txheej txheem tsim nyog rau qhov no. Txhawm rau kom sib dhos transceiver raws li tus txheej txheem no, koj yuav xav tau transistor, resistors, ib qho kev sojntsuam nyias, USB txuas, COM txuas, thiab xaim.
Kauj ruam 4
Muag lub resistor rau lub hauv paus ntawm qhov transistor, tom qab ntawd cam hlau mus rau hauv av mus rau emitter ntawm transistor. Muag lub resistor mus rau qhov kev sib sau ntawm cov transistor, xaim mus rau kev sib cuag thib ob ntawm COM ntsaws. Tom ntej no, cam cov xaim rau tus neeg sib txuas lus thib tsib thiab thib ob ntawm COM ntsaws. Txuas cov xaim liab ntawm USB rau 1Kohm resistor, cov xov hlau dub rau kab thib tsib ntawm tus COM ntsaws. Muag qhov kev sojntsuam mus rau 10 ohm resistor. Tiv thaiv cov khoom ntawm kev tawm dag zog ntawm lub cev sab nraud thiab qhov luv.
Kauj ruam 5
Khij lub transceiver ua, rau qhov no rub tawm thiab nruab qhov kev pab cuam Realterm, rau qhov no mus rau kab ntawv txuas https://realterm.sourceforge.net/index.html#downloads_Download, rub lub program. Nruab nws rau koj lub khoos phis tawm, kaw nws. Txuas lub transceiver rau COM thiab USB ports ntawm koj lub computer.
Kauj Ruam 6
Qhib koj lub computer, khiav daim ntawv thov. tig lub computer thiab pib qhov program. Mus rau kab "Chaw nres nkoj" thiab xaiv qhov chaw nres nkoj uas koj txuas nrog lub transceiver. Tom qab ntawv nyem khawm "Qhib", muab tso rau hauv cov xov nias. Yog tias cov cim daj tshwm ntawm qhov screen, ces tus transceiver ua haujlwm. Yog tias tsis yog, sim kov cov dipstick. Sim siv cov transceiver txawm hais tias cov cim tsis tau txav mus los. Yog hais tias tus transceiver tsis ua haujlwm thawj zaug, siv lwm lub ntsiab thiab kos cov soldering.
