o Receive ine signal detect! dengan saluran ini D"# memberitahukan ke D$# bah%a pada

terminal masukkan ada data masuk&

o Receive Data! digunakan D$# menerima data dari D"#&

o $ransmit Data! digunakan D$# mengirimkan data ke D"#&

Antarmuka Kanal serial lebih kompleks0sulit dibandingkan dengan antarmuka melalui

kanal paralel! hal ini disebabkan karena:

1& Dari Segi perangkat keras: adan'a proses konversi data pararel men,adi serial atau

sebalikn'a menggunakan piranti tambahan 'ang disebut AR$(Universal Asynchronous

Receiver/Transmitter)

2& Dari Segi perangkat lunak: lebih ban'ak register 'ang digunakan atau terlibat

4amun di sisi lain antarmuka kanal serial mena%arkan berapa kelebihan dibandingkan

secara paralel! antara lain:

tegangan dalam komunikasi serial memiliki a'unan tegangan maksimum 78 volt!

sedangkan pada komunikasi paralel han'a 7 volt& al ini men'ebabkan gangguan pada

kabel)kabel pan,ang lebih mudah diatasi dibandingkan pada paralel

Ada 2 macam cara komunikasi data serial 'aitu Sinkron dan Asinkron& ada

komunikasi data serial sinkron! clock dikirimkan bersama sama dengan data serial! tetapi

clock tersebut dibangkitkan sendiri > sendiri baik pada sisi pengirim maupun penerima&

Sedangkan pada komunikasi serial asinkron tidak diperlukan clock karena data dikirimkan

dengan kecepatan tertentu 'ang sama baik pada pengirim 0 penerima& RS232 metode
