How to find my STB has optical or coaxial output

[rasul.dhawooth]

Hi Friends,

Last Sunday i have upgraded my stb to HD box. In my HD box , there is an orange colored output port which is written as S/P DIF ... Is it coaxial output or optical out?

i have to buy HT system accordingly.. Pls help to find ...

S/P DIF can be mentioned for both Optical and Co-axial.....

If its a orange colored circular port, its is Co-axial... if it is a grey/black colored square shaped port it is Optical....

you can see details of Optical port/cable here: TUTORIAL: OPTICAL CABLE explained
