Tus nqi siab ua haujlwm thiab ntau yam 4G DTU
Terminal kev twb kev txuas qauv tsim, yooj yim dua rau kev lag luam daim ntawv thov, txhawb kev sau ntawv, kuj tuaj yeem khaws cov ntaub ntawv los ntawm kev ntsuas thiab bidirectionalpob tshab kis tau tus mob.
Hardware Description
Siv ZTE kev sib txuas lus chips, txhawb 7 qauv 15 zaus hom 4G network, nyob rau hauv rooj plaub ntawm 4G network tsis ruaj khov, nws tuaj yeem hloov mus rau 2/3G network kom ntseeg tau tias cov cuab yeej txuas tas li, thiab hloov mus rau 4G network thaum 4G. network tau rov qab los.

Main Function Description
Txhawb ntau txoj cai
TCP-ZSD / UDP-ZSD
Raws li Lub Siab ntim TCP / UDP qauv. Cov pob SKD muab los ntawm peb txhawb ntau lub programming lus kev loj hlob ib puag ncig, cov neeg siv tau yooj yim mus ntsib cov ntaub ntawv chaw tsis muaj kev txhawj xeeb txog cov txheej txheem network nyuaj. txhawb IP zoo li qub, dynamic domain, APN ntiag tug network.
HTTP raws tu qauv
HTTP raws tu qauv tuaj yeem siv los ua tus neeg siv HTTP rau kev xa cov ntaub ntawv thiab kev sib txuas lus bidirectional nrog HTTP neeg rau zaub mov kom yooj yim rau kev txhim kho nyuaj.
Siv LUB HTTP raws tu qauv, thaum lub chaw nres nkoj muaj cov ntaub ntawv xa mus, nws tsim kev sib txuas nrog cov neeg rau zaub mov thiab xa DTU ID thiab sau cov ntaub ntawv rau txhua tus HTTP server los ntawm HTTP post lossis HTTP tau txais. Ua li no, cov ntaub ntawv sau los ntawm DTU tuaj yeem pom ncaj qha rau ntawm WEB sab.
Virtual Serial Port Function
Siv virtual serial chaw nres nkoj thev naus laus zis, nws muaj peev xwm tsim kom muaj kev sib txuas ceev 4G wireless sib txuas ntawm lub chaw nres nkoj serial thiab lub khoos phis tawj tswj hwm hauv cov ntaub ntawv chaw los ntawm DTU thiab ua kom muaj kev sib txuas virtual, uas yog nrog thawj qhov chaw nres nkoj ntawm qhov kev pab cuam. tus neeg siv khoom siv.
Local/Remote Upgrade
txhawb tej thaj chaw deb configuration tsis thiab txawj tej yam ntxiv firmware ntawm saib center, tus ntaus ntawv yuav ua hauj lwm li qub thaum kho dua tshiab remotely.
Script programming overturns cov tsoos DTU, uas tsuas muaj kev ua haujlwm ntawm cov ntaub ntawv xa mus, thiab hloov MDD3411 rau hauv DTU ntaus ntawv nrog kev ua haujlwm tau.
Nco ntsoov DTU hauv zos acquisition script instruction user manual
txawv ntawm DTU ua ntej, MDD3411 txhawb nqa tsab ntawv tsis siv neeg nrhiav haujlwm. Siv cov ntawv qhia, cov neeg siv tuaj yeem txhais cov ntaub ntawv tau yooj yim, txo cov nqi kho vajtse zoo heev.
Txhais qhov kev yuav khoom hauv zos ua tau yooj yim
Cov ntawv sau kev cai tuaj yeem paub qhov tsis siv neeg tau txais ntawm cov khoom siv sab nraud thiab cov ntaub ntawv ntsuas los ntawm DTU yam tsis tas yuav tsum tau rau tus neeg siv los ntxiv cov maub los cais.DTU lub sijhawm tsis siv neeg tau txais tuaj yeem pom tau los ntawm tsab ntawv qhia los teeb tsa DTU, uas txo cov nqi kho vajtse zoo heev. Tsab ntawv paub txog lub luag haujlwm tseem ceeb ntawm kev hloov pauv, tswj kev ncua sijhawm, kev qhia tawm, kev tswj kev ncig, kev tshaj tawm kev tswj hwm, ntxig cov lus qhia header, thiab seb puas yuav lees txais qhov hloov pauv ntawm baud tus nqi ntawm cov cuab yeej teb, thiab lwm yam, uas tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm feem ntau cov twj paj nruag.
MDD3411 txais cov cuab yeej ua haujlwm siab heev
Nrog rau qhov chaw nres nkoj overcurrent, overvoltage, anti-reverse kev twb kev txuas thiab anti-surge tiv thaiv, industrial-qib zoo, ruaj khov ua hauj lwm ntawm -40 ~ 85 ℃; Yog hais tias cov xaim kev twb kev txuas yog unexpectedly reversed thiab qhov chaw nres nkoj yog luv luv, lub cuab yeej yuav tsis tau. puas lawm, thiab nws tuaj yeem siv tau ib txwm siv tom qab rov txuas dua.
