2SIO silkscreen error

If you're building one of Grant's 2SIO boards, be aware that the silkscreen is incorrect for D3, D6, D9, D12, D15 & D18. The cathode should be up toward the Molex connectors, instead of down as shown on the silkscreen.

This matters only if you are configuring the board for a current loop device, those diodes are not used if you are configuring it for RS232.

Geoff.
