Product Description

1. Description 

○ Digital Broadcasting 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.  

○ Maximum 11 cards can be installed in main shelf and it can be composed by
    expanding shelves.

○ Cards from main shelf can be replaced any moment if necessary, so it is 
    possible to provide fast after sales service.
