Thaum nyob hauv hom kev nyab xeeb, khiav NI-USRP Configuration Utility los hloov qhov chaw nyob IP los ntawm lub neej ntawd, 192.168.10.2, mus rau tus nqi tshiab.
Lub hwj chim voj voog lub cuab yeej tsis tuav lub khawm hom kev nyab xeeb kom rov qab tau hom qub.
Nco tseg NI xav kom koj siv lub network tshwj xeeb uas tsis muaj lwm yam khoom siv USRP txuas nrog lub khoos phis tawj tswj hwm kom tsis txhob muaj qhov teeb meem ntawm IP chaw nyob. Tsis tas li, xyuas kom meej tias qhov chaw nyob IP zoo li qub ntawm tus tswv tsev network adapter ntawm lub khoos phis tawj uas khiav NI-USRP Configuration Utility txawv ntawm lub cuab yeej IP chaw nyob. 192.168.10.2 thiab txawv ntawm qhov chaw nyob IP tshiab uas koj xav teeb tsa lub cuab yeej.
Nco tseg Yog hais tias tus ntaus ntawv IP chaw nyob yog nyob rau ntawm ib tug sib txawv subnet los ntawm tus tswv network adapter, lub host system thiab configuration utility tsis tuaj yeem sib txuas lus nrog thiab teeb tsa lub cuab yeej. Rau example, tus nqi hluav taws xob lees paub, tab sis tsis tuaj yeem teeb tsa lub cuab yeej nrog qhov chaw nyob IP ntawm 192.168.11.2 txuas nrog tus tswv network adapter nrog tus IP chaw nyob zoo li qub ntawm 192.168.10.1 thiab subnet mask ntawm 255.255.255.0. Txhawm rau sib txuas lus nrog thiab teeb tsa lub cuab yeej, hloov tus tswv network adapter mus rau qhov chaw nyob IP zoo li qub ntawm tib lub subnet li lub cuab yeej, xws li 192.168.11.1, lossis hloov lub ntsej muag subnet ntawm tus tswv tsev network adapter kom paub txog ntau yam ntawm IP chaw nyob, xws li 255.255.0.0.
