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
