Tsegulani ndikusunga zomwe zatsekedwa files ku chikwatu pa kompyuta yanu. Pamene mawindo akufunsa malo oyendetsa chipangizocho, lowetsani bukhuli. Dalaivala wa chipangizocho amasainidwa ndi digito ndipo amayenda mu Windows XP, Vista, 7, 8 ndi 10.
Kompyutayo idzakhazikitsa doko la COM lomwe likuyenda mumayendedwe a CDC. Advantage wa doko la COM ndilokuti chipangizochi chitha kuwongoleredwa pogwiritsa ntchito malamulo a ASCII osavuta kugwiritsa ntchito.
Mukangoyika dalaivala, VS11/12 idzadziwika ndi dongosolo.
Kukuthandizani kukhazikitsa magawo ndi kuyeza, pulogalamu ya PC VS1x imaperekedwa kudzera pa ulalo womwe uli pamwambapa. Unzip a file vs1x.zip mu bukhu la pakompyuta yanu ndiyeno yambitsani setup.exe. Maulalo oyika akhoza kusinthidwa ngati pakufunika. Pulogalamuyi ndi LabView kugwiritsa ntchito ndipo pachifukwa ichi amayika zigawo zingapo za LabView Malo a Run-Time kuchokera ku National Instruments.
Mukayika, pulogalamuyo (Chithunzi 3) ili pansi pa Metra Radebeul pamayambiriro a kompyuta yanu.

Kuphatikiza kwa VS11/12 ndi Mapulogalamu ena

Mapulogalamu operekedwa ndi Metra ndi amodzi okhaample ya PC yolamulidwa ndi parametrization ndi kuyeza ndi VS11/12. Pulogalamuyi idapangidwa ndi LabView 2014.
Pakuphatikizira zida kumapulogalamu ena apulogalamu Metra ipereka malangizo a ASCII ndi LabuView deta ya polojekiti, pakupempha.

Kusintha kwa Firmware

Ngati pulogalamu yatsopano (firmware) ya VS11/12 yanu ilipo mutha kuyiyika nokha. Chonde tsegulani web adilesi ili pansipa kuti muwone mtundu waposachedwa:
https://mmf.de/en/produkt/vs11.
Firmware ndi yofanana pazida zonse za VS1x.
Lumikizani VS11/12 kudzera pa chingwe cha USB ku PC ndipo fufuzani mu pulogalamu yokhazikitsira mtundu wa firmware woyikiratu wa switch yanu yogwedezeka (Chithunzi 3). Ngati nambala yamtunduwu ikuwonetsedwa pa web Tsamba liyenera kukhala lapamwamba kutsitsa firmware file, tsegulani ndikusunga ku chikwatu chomwe mukufuna.
Ikani komanso kuchokera pamwamba web tsamba pulogalamu "Firmware Updater".
Konzani zosintha za vibration kuti zisinthidwe podina batani "Firmware up-date" mu pulogalamu yokhazikitsira ndikutsimikizira chenjezo. Firmware yakale tsopano ichotsedwa (Chithunzi 15). Yambani "Firmware Updater", sankhani mtundu wa chipangizo "VS1x" ndikusankha doko la COM lomwe limagwiritsidwa ntchito polumikizira USB. Dinani "Katundu" batani ndi kulowa chikwatu cha dawunilodi fimuweya file vs1x.hex. Kenako dinani "Tumizani" kuti muyambe ndondomekoyi. Kupita patsogolo kudzawonetsedwa ndi bar graph. Pambuyo posintha bwino, kusintha kwa vibration kuyambiranso ndipo "Firmware Updater" idzatsekedwa.
Chonde musasokoneze ndondomekoyi. Pambuyo pa zolakwika zosintha mukhoza kuyambanso "Firmware Updater".
