Oops, I left that part out. All bits are O between tool positions, then each tool position is output in binary as you indicated above. You get 0000 0001 0000 0010 0000 0011 0000 0100 ... etc. I have the EMC files for my turret available here: http://www.wallacecompany.com/cnc_lathe/HNC/emc2/ The board is easy to test by putting +12 V on the brown wire (double check with your schematics), ground to the black wire and measure the voltage on the outputs (I think A=red=one, B=orn=two, C=yel=four, D=grn=eight). The Halls are only activated by the North pole. So if you can't trigger them turn your test magnet over and try again. The encapsulation on my board fell apart, so I removed it since it was not doing anything anyway. I replaced most of the seals in the carriage, so there is very little, if any, oil getting into this area. I figured, I could fix the board when it becomes a problem. I could not find any information on the number on the chips, but the CD4532 seems to be a match. If you would like to encode with one chip, the CD40147 would work. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC/EMC CNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending Craftsman AA 109 restoration Shizuoka ST-N/EMC CNC) ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
