RS232 rau RS485 RS422 Serial Converter Description
Lub RS232 rau RS-422/485 serial converter yog ib tug bidirectional adapter uas tso cai rau koj mus hloov RS232 cov ntaub ntawv qhia rau RS485 (2-hlau los yog 4-hlau) los yog RS422 thiab vice versa.
RS232 thiab RS485/422 davhlau ya nyob twg blocks yog detachable
Nws hloov RS232 teeb liab mus rau ib nrab-duplex RS-485 sib npaug sib txawv teeb liab thiab RS-422 tag nrho-duplex signals. Txhawb baud tus nqi mus txog 115.2 Kbps. Lub adapter txhawb nqa tsis siv neeg baud tus nqi kuaj pom zoo li RS-422 thiab RS485 hom kev kuaj pom thiab txhawb kev sib txuas mus txog 4000 ko taw (1200 meters).
Port-powered RS232 rau RS485 / RS422 converter yam ntxwv
- Hloov RS232 teeb liab mus rau ib nrab-duplex RS-485 sib npaug sib txawv teeb liab thiab RS-422 tag nrho-duplex signals.
- Lub RS232 rau RS-485 / RS-422 converter siv lub tshuab hluav taws xob sab hauv los muab lub zog los ntawm RS232 cov cim (RTS, DTR, TXD) yam tsis tau pib lub RS232 interface. Yog tias qhov chaw nres nkoj RS232 tsis tuaj yeem muab lub zog txaus, lub zog hluav taws xob sab nraud tuaj yeem txuas tau yooj yim rau lub converter davhlau ya nyob twg txuas.
- Zero-delay kis tau tus mob thiab qib siab I / O tswj tau tswj cov ntaub ntawv ntws.
- Built-in auto-sensing function cia li xaiv RS-485 lossis RS-422 hom raws li cov teeb liab txuas, tsis muaj jumpers.
- Txhawb nqa 2-hlau RS485 thiab 4- xaim RS422 kev sib txuas lus mus txog 300 - 115200bps.

RS232 Serial rau RS485 RS422 Converter Scope
Port-Powered RS232 rau RS485 / RS422 Converter yog ib yam khoom siv los hloov cov ntaub ntawv ntawm RS232 interface thiab RS485 lossis RS422 interface. Nws yog siv dav hauv cov xwm txheej uas cov khoom siv nrog cov txheej txheem sib txuas lus sib txawv yuav tsum tau sib txuas. Cov ntawv thov tshwj xeeb yog raws li hauv qab no:
- Industrial Automation Control: Feem ntau siv rau kev sib txuas lus hauv kev lag luam, xws li PLC (Programmable Logic Controller), sensors thiab lwm yam khoom siv, uas feem ntau siv RS485 lossis RS422 ua kev sib txuas lus.
- Tsev Automation: Hauv lub tsev automation systems, ntau yam khoom siv xws li ntsuas kub, cua txias controllers thiab of the elevator control systems siv RS485 kev sib txuas lus, thiab RS232 rau RS485 converters pab cov cuab yeej sib txuas lus nrog kev tswj hwm.
- Kev Tswj Hluav Taws Xob: Hauv kev tswj hwm hluav taws xob, xws li kev saib xyuas hluav taws xob, hnub ci thiab cua tshuab hluav taws xob, ntau cov khoom siv tswj tau siv RS485 / RS422 interfaces, thiab qhov hloov pauv no ua rau cov cuab yeej txuas nrog lub tshuab computer lossis lwm yam tswj los ntawm RS232 interface.
- Kev Ruaj Ntseg: Kev tswj lub koob yees duab, kev tswj xyuas qhov system thiab cov khoom siv sensor hauv kev saib xyuas kev ruaj ntseg feem ntau yog siv RS485 kev sib txuas lus raws tu qauv, thiab lub converter pab cov cuab yeej txuas nrog lub tshuab computer lossis lub ntsiab tswj.
- Kev txais cov ntaub ntawv nyob deb: Nws yog siv rau hauv cov xwm txheej uas yuav tsum tau txais cov ntaub ntawv chaw taws teeb thiab xa mus, thiab cov ntaub ntawv nyob deb tau xa mus rau lub hauv paus tswj hwm los ntawm kev sib txuas lus ntev ntawm RS485 / RS422.
