Tim,
The pulse multiplier will fit inside both the G201 and the G320. They
will be called the G210 and G340 respectively.
Three things may be of interest.
1) The multiplier can be jumpered to your choice of X1,X2,X4,X5 and
X10. This would make the G210 appear as a 10 uStep, 5 uStep, 2.5
uStep, half-step and full-step drive in that order. In all cases the
motor will turn with microstep smoothness.
2) The opto-isolator interface can be jumpered to be either common
anode (+5 VDC) as on the G201/G320 or common cathode (GND). This will
permit easier interface with a parallel port.
3) The multiplier in the servoamp will effectively reduce the
required step rate (4X the encoder line count) by 1,2,4,5 or 10 fold
while keeping the "dither" angle to (360/4X line count) degrees.
