SmartPrecision
Electronics Module
The Mercury 2000 encoder system includes a SmartPrecision
electronics module. This compact, fully-featured signal processing
system performs the following functions:
• Interpolation - up to 256X with 28.8 million quadrature states / sec.
• Programmable interpolation level and output bandwidth
• Accuracy optimization - sensor signals are automatically optimized
to improve system accuracy and maximize repeatability
• Signal strength indication - red / yellow / green LEDs assist during
setup and provide diagnostics at a glance
• Index centering - centers the bi-directional index output pulse for
repeatability to +/-1LSB
• Power-indicating LED
• Computer interface - for programming and data acquisition using
SmartPrecision software
• Superior EMI / RFI immunity - CE compliant
• Mounting options - all electronics are within the EMI-shielded
connector housing and can be screwed directly into a mating
connector that is bulkhead mounted, or the module may be mounted
to the frame of your motion system and connected using an
extension cable
SmartPrecision module enclosure provides “Best-in-Class”
noise immunity for high noise environments.

Programmable Interpolation
The electronics module has programmable interpolation that is
selectable over the range x4 to x256 in integer steps, providing output
resolutions that can be matched to your application requirements. This
feature provides linear resolutions from 5µm to 0.078µm in convenient
increments (e.g. x200 interpolation = 0.1µm) and rotary resolutions
from 6,600 CPR to 4.2M CPR. Specify the interpolation value at the
time of ordering or select the interpolation at your site using
SmartPrecision Software.

Programmable Maximum Output Frequency
For encoder applications combining high resolution and high speed,
the SmartPrecision electronics module supports up to 28.8 million
quadrature state changes per second**. By specifying the maximum
output frequency to match your controller's capability - ranging from
900,000 up to 28.8 million quadrature state changes per second - the
Mercury encoder system will never produce encoder counts faster than
your controller can read them. Specify the encoder’s maximum output
frequency at the time of ordering or select the setting at your site
using MicroE's SmartPrecision Software.
* The electronics module’s serial computer programming interface can be translated to be RS-232
compatible using the MicroE SmartPrecision Computer Interface Adapter or a voltage translation
circuit of your own design.
** “Quadrature state changes per second" is the reciprocal of "dwell time" or "edge separation". For
example, 28.8 million states per second = 0.035µsec dwell time.
