Special Functions and Features

Several special features have been incorporated into the stage control firmware beginning with
version 6.0a. Several of these functions are standard on every controller, others are only supported
with special hardware modifications or options; each are discussed in turn.

Configuration Flags

Beginning with firmware version 8.0, a set of configuration flags are read upon startup which
determines the axis profiles for standard build firmware. These flags determine whether linear or
rotary encoders are to be used, and the type of motor / lead screw combination used for the various
axes. The configuration flags may be changed using the 

“CCA X” commands

 or by switching the

encoder DIP switches. When a configuration flag is changed for an axis, new default parameter
settings are used for that axis. On most controllers the 

“CCA X?” commands

 will show the existing

configuration and show the other configurations available in the firmware.

Build Configuration

Users often request special features for their systems. Often there are special firmware modules that
are included to provide custom functionality. The BUILD X [BU X] command lists the firmware basic
build flavor and all of the special firmware modules that are included in the controller. The following
list describes some of these modules that may be present in your controller.

LL COMMANDS †

Low Level Command set is included

RING BUFFER †

Internal 50 position Ring Buffer is supported

SEARCH INDEX †

Supports ability to search for the index on linear encoders

TRACKING

Firmware module to support PhotoTrack system

AUTOFOCUS

Video autofocus scanning firmware module

SCAN MODULE

Supports 1-d and 2-d programmable scan patterns.

ARRAY MODULE

Firmware module for x,y moves in array pattern.

SPEED TRUTH

Query on SPEED command returns internal calculated speed used.

CRIFF

Firmware for the CRIFF focus system.

DAC OUT

WRDAC command sends specified voltage to SV1,Pin-5. On PZ_* builds, this
is the 0-10v output for commanded Z moves.

PREPULSE

Module to add predictive TTL output trigger pulse

PEDALS

Support for foot pedals to control Z-axis and Zoom systems

MULTIAXIS MOVES

Supports circular and spiral moves directly from the controller

CLOCKED POSITIONS Supports motorized objective turrets, filter turrets & filter wheels
TTL_REPORT_INT

TTL IN0 used for interrupt-driven encoder position reporting

ENC_INT

Interrupt line is used for encoder pulse counting with the SCAN MODULE
