Chiratidzo chechipiri chekudzivirira

Serial port mudziviriri ndeye plug-in adapta ine dziviriro yedunhu, iyo inoshandiswa kuchengetedza chiratidzo system nemidziyo, uye inogona kushandiswa mune yakanyanya kutapurirana zviitiko. Semuenzaniso, mugadziri uye sevha inochengetedza chiteshi inoiswa pamberi peiyo serial port. Iyo yakayerwa voltage ndeye 8V uye 12V, iyo yakanyanya kuburitsa ikozvino 15ka, uye chiyero chekufambisa data i1mbit / s. Nekudzivirira kwakanaka, iyo yakayerwa voltage i12V DC uye yakayerwa yekuburitsa ikozvino 100A (8 ~ 20 A) μ s) Iyo data yekufambisa chiyero i1mbit / s.

Coaxial cable chiratidzo chekudzivirira inoshandiswa kuchengetedza 75 Ω～ makumi mapfumbamwe nematatu Ω Iyo yakanyanya amplified ikozvino 20 Ka (8-20 KA) μ s) Nhamba yekufambisa data ndeye 16mbit / s. Iyo over-voltage inodzivirira yeantenna feeder (tambo yeTV tambo) yekutepfenyura setiraiti inoshandiswa kuchengetedza 75 kV Ω System zvishandiso, senge antenna amplifier, kutepfenyura setiraiti yekugamuchira sisitimu, nezvimwewo. Iyo yakanyanya kubuda ikozvino 3.5 Ka (8-20 MA. ) μ s) Iyo frequency renji ndeye 4-2050mhz.
