Hi Josh,
As you surmised, the additional components described below are for the active bus termination setup. As noted in the previous messages, some of the component leads such as IC socket & SIP resistors are too short to protrude through the other side of the board. While this is far from ideal, I didn't think it was a show stopper since all the holes are plated through. In my case the tip of the components was visible but not protruding so I just filled the pad with solder which provided the necessary continuity. Again, not ideal but my board worked out fine. Bob pointed out a problem with the fuses that I was not aware of in that they aren't really protecting anything but the LEDs. I have another blank board so I ohm'ed out the power input connector to the bus traces and there is continuity with no fuses installed. I followed the trace visually and just as Bob said, they go right to the bus.. I am glad that I am a little compulsive and also externally fused the power leads as the on board polyfuses could just be replaced with wire. Regarding Q1 I just checked the orientation and it matches the silkscreen but I this this is an earlier board so I can't speak about the V2 boards. The reference voltage adjusted fine and it seems to be working properly so I have to assume that Q1 is installed correctly on my board. On 12/23/2014 9:39 AM, Crusty OMO wrote:
