* review choice of filament flyback output diode
* invert LED position so that the Ethernet LED is closest to the connector
* invert polarity of LEDs (Ethernet LED polarity cannot be programmed)
* Meanwell DC/DC is coupling noise into pA input
* change D351 model to MBR1645
* add snubber on D351
* add heatsink (Seifert-KK633) to D351
* move D351 further away from transformer for heatsink clearance
* add plated-through holes and pads for mounting rods of BNC connector
* simplify FBI circuit, 2 ranges only (typ. 8mA and 45mA), remove diodes and neglect MOSFET leakage
* to support different case designs, replace the holes on the connectors side with slots. One of the case designs requires holes whose center is at 11.5mm from the board edge.
