I tried to connected an old BOB to the port 3 of my UC300ETH. Normally, there is 2 power ports (5VDC for the buffers and a VDD for the opto power. So I connected the 5VDC output of my UCBB to the 5VDC of the 5VDC of th eBOBO and the 24VDC to the VDD.

Could you tell me the value of the capacitor (I will try to replace it) and the value of one just aside (seemed not in a good shape neither)

Picture not embedded the right way, so it is not shown.

Here is the picture

Perhaps it's clear for everyone else except for me, but I don't know what this is. It certainly does not look like the UC300ETH.

Here's a pic, it's 10v 220uF capacitor

I think it's a UCBB.
