== Supply Termination Power ==
The SCSI2SD V5.1 and V6 boards can be modified to supply termination power back to the SCSI cable.

=== SMD soldering solution ===
# The pins at JP201 needs to be shorted. It's designed for a standard 0.1" jumper, but you could just put a paperclip in those pin holes.
# Add a schottky diode to D205 (SOD-123 package). The diode needs to be rated for at least 1A continuous current
#* Try [https://www.digikey.com/product-detail/en/micro-commercial-co/MBRX120LF-TP/MBRX120LF-TPMSCT-ND/2041570 MBRX120LF-TP]
#* Alternatively, desolder D203 and move it to D205.

=== Easy-soldering solution ===
# Use an axial schottky diode that supports at least 1A. eg. a 1N5817 diode.

# Solder the cathode lead (-) into the the JP201 pin hole closest to the power connector.
# Solder the anode lead (+) into the other JP201 hole.
# Short the two pads of D205 with a big blob of solder.
