ACC-51S

I've gone through the Encoder table setup several times, checked for my Lissajous pattern with the preamp connected to the ACC-51S and it looks good. I'm not getting any postion counts. When I try to view $78800 in a watch window I get the message Cannot read value.

 

Anyone have an idea where I might be going wrong?

According to page 16 of the ACC-51S Manual, the encoder address of channel 1 is $78000, not $78800, which is the ADC address of channel 1.

 

Also, keep in mind that your E1 jumper setting will affect the base address of the ACC-51S: it will be at $78800 if E1 is at pins 2-3, and $78820 if E1 is at pins 1-2. You must have your ECT entries read the correct base address based on E1's setting.
