Imiyalo yokusetshenziswa komkhiqizo
Ukufakwa
1. Qinisekisa ukuthi imoto ivaliwe ngaphambi kokufakwa.
2. Thola indawo efanelekile yokukhweza yemojuli ye-UM680A
ngokuchayeka kahle esibhakabhakeni ukuze uthole isignali ye-GNSS
ukwamukela.
3. Xhuma imojuli emthonjeni wamandla wemoto olandelayo
imininingwane kagesi eshiwo.
Ukusebenza
1. Amandla emotweni kanye nemojula ye-UM680A.
2. Vumela isikhathi esithile ukuze imojuli ithole amasignali esethelayithi
futhi usungule ukuma kwe-RTK.
3. Qapha ukunemba kokuma nokusebenza ku-
isibonisi esikhethiwe.
Imibuzo Evame Ukubuzwa (FAQ)
Q: Yini okufanele ngiyenze uma imojuli yehluleka ukuthola isathelayithi
izimpawu?
A: Hlola ukubekwa kwemojula ukuze uthole izithiyo ezivimba i-
Amasignali e-GNSS futhi aqinisekise ukunikezwa kwamandla okufanele.
Q: Ingabe imojula ye-UM680A ingasetshenziswa ezinhlelweni zasolwandle?
A: Cha, i-UM680A yakhelwe ukusetshenziswa kwezimoto futhi angeke
ukusebenza kahle ezindaweni zasolwandle.

3.2 Idizayini yokuphakela kwe-antenna
I-UM680A isekela ukuphakela i-antenna ngaphandle kwemojuli kunangaphakathi. Kunconywa ukusebenzisa amadivaysi anamandla aphezulu futhi angakwazi ukumelana nevolthi ephezulutage. Ishubhu yokukhipha igesi, i-varistor, ishubhu ye-TVS namanye amadivaysi okuvikela amandla aphezulu angasetshenziswa futhi kumjikelezo wokuphakelwa kwamandla ukuze kuqhutshekwe nokuvikela imojula ekushayweni kombani nasekuqhumeni.
Uma isiphakeli se-antenna sinikezela nge-ANT_BIAS kanye ne-VCC yemojuli eyinhloko isebenzisa ujantshi wamandla ofanayo, i-ESD, i-surge kanye ne-overvoltagi-e evela othini izoba nomthelela ku-VCC, okungase kudale umonakalo kumojuli. Ngakho-ke, kuyanconywa ukuthi udizayine i-ANT_BIAS ujantshi wamandla ozimele ukuze unciphise amathuba okulimala kwemojuli.
