Hello All
'
I just got My Spinneret
'
I've read through the doc's and I'm almost ready to wirer it up.
'
My Question is with J1.
'
I'm confused with the Spinneret schematic,and the J1 layout.
'
I'm not sure what pin is what?
'
I have an OHM Meter,But it's 9 volts for the ohm loop, And I'm afraid I'll zapp something on the Spinneret trying to ring-it out.(J1)
'
Is their a Board lay-out That I have not found that shows the pin lay-out for J1?
'
I've never let the smoke out of a Parallax device before.,I would like to keep it that way!
'
Any help with J1 would be great!

    If you look at the schematic and orient the board component-side-up so that J1 is on the left side, and the Ethernet connector is on the right, J1 in the schematic and J1 on the board will have the same orientation. IOW, with the board in this position, Vdd is the upper-lefthand corner pin, and +5V is the lower-righthand corner pin.

    One word of caution: J1 is a 2mm connector that accepts 0.020" square pins -- not the regular 0.025" square pins that 0.1" connectors use. So don't force any wires or pins into this socket that are much bigger than 0.020" in diameter. Doing so will risk springing the socket fingers, which will compromise it for subsequent use with daughterboards.
