Main control unit is a card type control device for large capacity equipment.
It is composed of main self which CPU and power supply are allocated. Each card unit works as communication control (RS-232C/ RS-422), input/output, volume up/down and IR control.
It provides maximum convenience as using cards which are replaceable at any moment for after sales service.
It controls the operating program or key pad by connecting various devices.
