Nasty Nasty X Spot

Just looked at the manual . . .

Flashing red on a 3 phase is "No Data". Assuming it was HD-1 that you got off by a pin, then there were two chances. If you got it in one direction, the 40V line would have hit ground, and probably taken out the power supply fuse. More likely you shifted it the other way, and that would have put 40V on one of the data lines into the card, and probably took out the input buffer chip, resulting in that error.

On the two phase, I see no reference to a puling green. Any chance that it is going green/yellow? If so, then that would indicate that you have two cards addressed the same . . . which would explain also quite well why one is not functioning . . . on the dual litho, make sure that he only addressing screw is on the top left, next to HD-1 . .

On the fuse, assuming that is a 2 phase card, the fuses there each protect two of the four motor channels, so if one pops, two outputs die. Try unplugging the motors and see if it still blows, then add motors one at a time. If it then goes, the last motor you plugged is either bad or has a cable short. If it blows anyhow, take out the two motor driver chips and repeat the test. If you need an extra to test with, the fourth motor channel on the litho/iris card is not used, and the driver chip can be used as a spare (thanks to Chris at HES for putting me onto that one!).

Oh, and on the dual litho 2 phase, the channel assignments are as follows:

U9/M1 - FX Rotate
U10/M2 - Litho 1 Wheel
U11/M3 - FX Wheel
U12/M4 - Litho 1 Rotate

S1 - FX/L1 Wheel
S2 - FX Rot
S3 - L1 Rot
S4 - Not used

Where the "U" is driver chip number, the "M" is motor channel, and "S" is sensor channel . . .

Hope this helps . . .
