CAN Communication

• Umum – – – –

Umum Apakah CAN? CANadalah singkatan dari Controller Area Network. CANmerupakan protokol komunikasi serial yang terstandarisasi secara internasional pada ISO yang dibuat oleh BOSCH pada tahun 1986

Keunggulan dari CAN • Komunikasi Kecepatan Tinggi dengan volume data yang besar • Mengurangi wiring harness • Transmisi data yang Handal 53
