Liiska Qiimaha ee Rs485 422 Beddelka - Beddelka Taxanaha ilaa E1 JHA-CE1Q1 - JHA

Beddelka E1-RS422JHA-CE1Q1

Dulmar

Beddelaha interneedku wuxuu ku salaysan yahay FPGA, isagoo bixinaya hal interface E1 iyo hal interface serial RS422. Alaabtu waxay jebisaa is burinaya inta u dhaxaysa fogaanta isgaadhsiinta is dhexgalka dhaqameed iyo heerka isgaadhsiinta, ka sokow, waxay sidoo kale xallin kartaa faragelinta korantada, faragelinta giraanta dhulka iyo dhaawaca hillaaca. Qalabku wuxuu si weyn u wanaajiyaa isku halaynta, amniga iyo sirta isgaarsiinta xogta. Waxaa si weyn loogu isticmaalaa xakamaynta warshadaha kala duwan, xakamaynta habka iyo munaasabadaha xakamaynta taraafikada, gaar ahaan Bankiga, iyo Power iyo qaybaha kale iyo nidaamyada kuwaas oo leh shuruudaha gaarka ah ee deegaanka faragelinta elektromagnetic. Heerka is-gaarsiinta is-dhex galka serial waa ilaa 512KBPS.
