Hello,

what is the right way to use the (new) 4:1 Mux/Demux Digital Switch and 4-Input Selection Switch (this version has a place for Jumper J1) for Buffalo IIIse?

I have connected 5V and GND to booth boards (on 4-Input Selection Switch to header: pin 2 and 4). Led light up when i turn the switch but there seems not to be a signal changing.
Should header pin 6 (low) go to S0 and pin 8 (high) to S1 on Mux board? have I to use the jumper?

Thx

Here's a connection diagram. I am putting this on the MUX web page as well.

Referring to Brian's post above, is the product with the layout below (CS8416 4:1) connected in the same way to the updated switch board that contains J1?

Leave J1 open and no special wire jumpers at the switch as with the earlier board revision?

For the 4:1 Mux Receiver, add the J1 jumper. That was added just for it.

Hi,

as I had problems to get my 4:1 mux to working state we tested it today with a friends mux that works fine.
The only visible difference is that his resistor array is mounted the other way them mine.
Is this the problem or could it be the smd chip?

what are the part numbers to look for to replace the buddies?
