Khoom Description

Cisco CAB-449MT DTE Txiv neej RS-449 Cable yog siab -kev ua tau zoo RS-449 serial data cable tsim tshwj xeeb rau cov khoom siv Cisco. Qhov no cable nta ib tug LFH60 txiv neej connector ntawm ib kawg thiab ib tug DB37 txiv neej connector nyob rau hauv lub lwm yam, ua rau nws haum rau kev sib txuas Cisco routers, keyboards, thiab lwm yam DTE (Data Terminal Equipment) rau cov khoom uas txhawb RS-449 raws tu qauv. RS-449 raws tu qauv txhawb nqa ntau lub teeb liab kis tau tus mob, suav nrog cov ntaub ntawv xa mus, tau txais cov cim qhia, thiab tswj cov cim, tso cai rau kev sib kis ntawm ntau cov ntaub ntawv ntws thiab ua kom muaj peev xwm sib kis tau zoo. PCM-KW-604 txhawb nqa cov ntaub ntawv siab thiab qis latency, tswj kev ua tau zoo, tshwj xeeb tshaj yog nyob rau hauv high-load network thiab cov ntaub ntawv sib pauv scenarios.

FAQ

Q1: Dab tsi yog qhov txawv ntawm RS232 thiab RS449 raws tu qauv?

Qhov chaw txiav ntawm qhov ntsug kawg zeb me ntsis (yog rau milling) yog nyob rau ntawm nws sab, tsim rau txiav kab rov tav, lub laum me ntsis (yog rau drilling) txiav nto yog nyob rau ntawm nws lub ntsis, tsim los txiav vertically downward .. koj yuav pom tias qhov kawg zeb feem ntau muaj lub tiaj tus ntawm qhov kawg ntawm lub ntsis.

A1: Piv rau RS-232 raws tu qauv, RS-449 txhawb kev xa cov ntaub ntawv ntau dua (txog 2 Mbps) thiab kev sib kis ntev dua (feem ntau 50 ko taw lossis ntau dua).
Tsis tas li ntawd, RS-449 txhais cov kab teeb liab ntau dua li RS-232, feem ntau siv DB37 txuas nrog ntau tus pins (txog 37 tus pins), muab kev ua haujlwm zoo dua qub. Piv nrog rau RS-232, RS-449 muaj ntau dua ua tiav cov teeb liab hauv av thiab tswj cov teeb liab, ua kom ntseeg tau cov ntaub ntawv hloov pauv ntau dua.

Dab tsi yog cov yam ntxwv hluav taws xob ntawm RS449 raws tu qauv?

Q2: Dab tsi yog cov yam ntxwv hluav taws xob ntawm RS449 raws tu qauv?

A2: Nyob rau hauv RS-449, lub logic "1" feem ntau yog sawv cev los ntawm +12V teeb liab, thaum lub logical "0" yog sawv cev los ntawm -12V teeb liab. Qhov no zoo ib yam li qhov zoo thiab tsis zoo voltages siv nyob rau hauv RS-232 (feem ntau ± 3V rau ± 15V), tab sis RS-449 muaj stricter voltage ntau specifications, feem ntau yuav tsum tau lub voltage nyob rau hauv lub ± 12V ntau yam. Qhov sib txawv ntawm qhov hluav taws xob ntau dua no muab kev tiv thaiv hluav taws xob ntau dua, tso cai rau kev xa cov ntaub ntawv ruaj khov hauv ib puag ncig nrog kev cuam tshuam electromagnetic (EMI) thiab suab nrov.
