hi. We have used novastar for 6 years on our vid wall processors and video walls   We just installed a new 2.5 wall we have two problems.  One we can’t find the five wire ribbon cables to connect the novastar msd300 sending cards together so it will program 2nd half of screen one one processor.    

2nd problem.  We have bands of dark and light colors in even spaced columns across the screen.  We can send pics.

Could you please tell me whether you can not find the wire ribbon cable or the software can not link?

2nd problem,please send pictures both of the screen and receiving card parameters to support@novastar.tech,I will check the problem.

Hi, we got the bands fixed.  

We do not have the wires to connect the two msd 300 sending cards together so the processor  can run the entire screen.   We have to have both cards and all four ports.

So you want to control the brightness of the entire screen by using the wires?

I want to program the sending cards.  The machine only sees one card unless I connect  them.

You can use this cascade line in the attach.

You can contact with the guy you purchased the card to get this cascade,or maybe look for it from the electronic market.

The cascade should be connected from the output port of the first card to the input port of the second card,please check if it is correct?

The output port and the input port can be seen ong the card.

Like the attach!

Yes. It works in one processor but not the second.  We even tried different sending cards

So we have tried the cascade in four processors two 605s and two 615s. LVP.   When we use the identify cards in LCT mars. It only shows card one.  We are going out from one MSD 300 card via 5pin 2.5 m ribbon wire to the second MSD 300 card. Both cards have power.  The first card does program.  The second card does transmit image but obviously isn’t configured as it is not seen by software.  

We have another r615s that has the same cards and ribbon cable and it works.    So we do not understand what is wrong.   Is there a setting in the processor that recognizes the second card.
