SER1_TX not functioning properly
During prototype hardware test it was observed that the SER1_TX signal was not functioning properly. This is due to the absence of a 4.7kΩ pull-down resistor on SER1_TX in the design of the PXIeCOMe rev 0.4.
Explanation
see #52 (closed)
Fix
After applying the 4.7kΩ patch resistor (0402) between SER1_TX and its neighboring GND via on the top layer, SER1_TX is functioning properly.
