Samun tsarin
Hanya mafi sauƙi don samun damar tsarin ita ce haɗa shi zuwa hanyar sadarwa tare da sabis na DHCP da shiga ta hanyar SSH.
Haɗa kebul na Ethernet kuma ka tabbata ka ga LEDs na tashar tashar Ethernet tana aiki.
Yi amfani da aikace-aikacen abokin ciniki na SSH da kuka fi so daga kwamfutar mai masaukin ku da aka haɗa zuwa cibiyar sadarwa iri ɗaya kuma yi amfani da "raspberrypi.local" azaman adireshin. Misali, daga tashar Linux: $ ssh pi@raspberrypi.local
Idan haɗin ya yi nasara, shigar da kalmar wucewa ("rasberi") kuma kuna shirye don amfani da Strato Pi CM.
Idan haɗin bai yi nasara ba, gwada yin ping "raspberrypi.local". Idan rukunin ya amsa, ya kamata ku iya ganin adireshin IP ɗin sa a cikin martanin ping, don haka kuna iya ƙoƙarin amfani da wannan IP don haɗin SSH, misali: $ ssh pi@192.168.1.13
Idan ba ku sami damar dawo da adireshin IP na rukunin ba, sami dama ga na'ura mai ba da hanya tsakanin hanyoyin sadarwa, modem, ko kwamitin kula da uwar garken DHCP kuma nemo adireshin IP ɗin da aka sanya wa Strato Pi.
A madadin, yi amfani da aikace-aikacen na'urar daukar hoto na cibiyar sadarwa don jera duk na'urorin da aka haɗa zuwa cibiyar sadarwar kuma bincika Strato Pi.
A kowane hali, yakamata ya bayyana akan hanyar sadarwar azaman daidaitaccen allon Rasberi Pi.
Idan duk abubuwan da ke sama sun kasa ko kuma ba ku da hanyar sadarwa ta DHCP don yin aiki a kai, kuna iya ƙoƙarin haɗa Strato Pi CM tare da kebul na Ethernet kai tsaye zuwa tashar Ethernet mai masaukin ku. Dangane da OS na kwamfutarka da saitin hanyar sadarwa za ku iya isa ga naúrar kamar yadda aka bayyana a sama.
Zaɓin na ƙarshe shine samun dama ga na'ura wasan bidiyo ta hanyar RS-485 serial interface kamar yadda aka bayyana a sama. Daga nan zaku iya shiga buga sunan mai amfani (pi) da kalmar wucewa (rasberi) kuma duba adireshin IP na rukunin ta amfani da umarnin “ifconfig”.
Kuna iya amfani da tsarin kai tsaye ta hanyar RS-485 serial console; ba shi da amfani sosai, amma mai yiwuwa.
