Sensor Offset. This is an objective specific offset that should be
set before data is collected off the sensor array. Each value is a
multiple of 8. The default is 2, which means that 2 x 8 = 16 pixels
of the linear array will be ignored before data is captured. This
command will allow the system to ignore a section of the array
data when determining the focus position. Values are from 0x0000
to 0x0020. A “?” will return the current offset value.

Speed. Sets the motor clock speed output. A “?” will return the
active speed. The last speed changed is by default the active speed
and the motor will move at that speed if no other commands are
altered before the move command is sent. Step rates are 16 bit hex
values based on the following decimal calculations:
Rate = 20,000,000/(65,536-Value)
Value = 65,536 – (20,000,000/Rate)
The maximum step rate available is ~80KHz or a decimal value of
65300. Rates above 10KHz may have an error of ~10%. A “H”
parameter sets the high speed value that is used when the focus is
outside of the docking area. A “L” parameter sets the low speed
which is used once focus is inside the docking range.
SP M
Speed Maximum. This command returns the current max speed
for the system. Values will range from 0x0000 to 0xFFFF.
SS
System Status. Returns two bytes that indicate the status of
various system states.

Stop. Stops motor movement. This will stop the motor and take it
out of auto motor mode if enabled.
VN
Version Number. Returns the firmware revision number as a 3-
digit number followed by a release Alpha character in the format
“m.nnr”, where m = major version, n = minor version and r is the
release build. Ex: 1.22A.
