Response Description
R Move to absolute position z
Sets the z-axis backlash value for z-axis move commands sent via the serial
port (not joystick moves) to b. s = 1 enables backlash s = 0 disables
0 backlash. b is the number of microsteps per motor. There are 50,000
microsteps per revolution of the motor on a standard ProScan focus
system.
Enables / Disables the z-axis backlash. s = 1 enables backlash s = 0 disables
0
backlash.
Reports back s and b values for z-axis moves sent via the serial port (see
s,b
above). In compatibility mode only s returned
Sets the z-axis backlash value for joystick/digipot moves to b in microsteps.
0
s = 1 enables backlash s = 0 disables backlash.
Enables / Disables the z-axis backlash for joystick/digipot control. s = 1
0
enables backlash s = 0 disables backlash.
Reports s and b values for z-axis (see above). In compatibility mode only s
s,b
returned
w Reports the current step size for the z-axis focus motor.
0 Sets the current step size for the z-axis focus motor to w.
R Moves down by z steps.
R Moves down w steps defined by the 'C' command.
R Moves Up by z steps.
R Moves Up by w steps defined by the 'C' command.
R Go to the absolute position z in the z-axis.
Prints information about z-axis focus unit.
The information end is always a line saying END. This allows for the
addition of extra fields of information without affecting application
software. Users should always read lines in until the END is seen to keep
in sync.
Text string
Example
FOCUS = NORMAL
TYPE = 0
MICRONS/REV = 100
END
0 Sets the stage and focus position to ZERO (0,0,0).
R Move to absolute position z
Sets the z-axis backlash value for z-axis move commands sent via the serial
port (not joystick moves) to b. s = 1 enables backlash s = 0 disables
0 backlash. b is the number of microsteps per motor. There are 50,000
microsteps per revolution of the motor on a standard ProScan focus
system.
0 Sets the direction of Z axis under digipot control. d = 1 or -1.
d Reads d.
R Moves stage and focus to zero ( 0,0,0 )
Sets the speed of the focus motor under joystick/digipot control. s is
0
percentage in range 1 to 100.
Reports value of OF allowing for joystick speed buttons effect (if the
S
button speed is ½ and OF is set to 50 the returned value will be 25)
Z Reports position of z only.
Sets absolute position of z axis. No axis can be moving for this command
to work. If an encoder is present on the Z axis, the position is only set
0
when the current position is in the encoder range (it must have been
further down than it is currently).
