Beddelka Wajiga Rs232 ilaa Rs485 - E1-RS485 Beddelka JHA-CE1D1 - JHA

E1-RS485 bedelayr JHA-CE1D1

Dulmar

Beddelaha interface-ku wuxuu ku salaysan yahay FPGA, oo bixiya hal E1 interface iyo hal RS485 interface interface, 1Channel RS485 gudbinta E1 interface. 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 921.6KBPS.

Astaamaha

• Iyada oo ku saleysan is-copyright IC
• Wuxuu si toos ah u ogaan karaa oo u xakameyn karaa socodka xogta RS-485 iyada oo aan la helin calaamado gacan qaad si loo xakameeyo jihada xogta
• Awood u yeelo inaad si toos ah u ogaato heerka baud ee signalka dekeda taxan
• Si otomaatig ah u tijaabi sababta qalabka matt waa in qalabku uu dansan yahay, ama khadka E1 uu jabay. Ka dibna ku muuji LED-ka
• Bixi 2 caqabadood: 75 Ohm dheelitir la'aanta iyo dheelitirka 120 Ohm;
• Taageerida Maamulka Shabakadda SNMP
• Kanaalka taxan waxa uu u gudbin karaa xogta taxanaha ah ee la qabsan karo si isku mid ah 300 Kbps-921.6Kbps heerka baud
• Isku dhufashada xogta taxanaha ah ee E1 waxay taageertaa ITU-T R.111 qaabka koodka boodboodka
• Serial port interface hillaac-ilaalin gaadhay IEC61000-4-5 (8/20μS) DM (Qaabka kala duwan): 6KV, Impedance (2 Ohm), CM (Common Mode): 6KV, Impedance (2 Ohm) heerka
