BR?, BR # Baud Rate. Selects between two different RS-232 baud rates. A
“1” selects the high baud rate of 57600 with even parity and 8 data
bits and 1stop bit. A “0” selects a low baud rate of 9600 no parity
and 8 data bits and 1stop bit. The default is the high baud rate. This
command will executed after a power cycle of the unit.
CD #, CD?
Change and Disable. This command will disable the auto focus,
change the objective to the given parameter, move the stage to a
nominal focus position and evoke the offset based on the CO
command for the given objective, then re-enable the auto focus.
Each objective may have a specific offset value associated with it
for calibration purposes. Values are from 0 to 7. A “?” will return
the current objective number being used.
CE #, CE?
Change Enable. A “1” enables the auto focus, but first checks to
see if the data is valid. If the data is not valid, then a “?4” will be
returned. If the data is valid, the auto focus will be enabled as well
as the motor movement. A “0” will disable it. A “?” will return the
current value.
CM ±
Continuous Move. When in manual motor mode, issuing a
continuous move will start moving the motor in the commanded
direction until either a limit is hit or a stop (ST) command is
received.
CO ####, CO?
Change Offset. A ± motor step offset value that allows for optimal
positioning between objective changes. This value will be an offset
from some reference position such as the lowest magnification
objective. Values range from 0x7FFF (+32767) to 0x8001(-
32767). A 2’s compliment method is utilized to represent
maximum decimal values of ±32767. The parameter is a 4 digit
hex value. A “?” will return the current value.
DR ####, DR?
Docking Range. A ± range that the signal can be within before the
Docking Range bit is set. When the focus is within this window,
the stage speed will be reduced to the slower speed. Values are
from 0x0000 to 0xFFFF. A “?” will return the current value.
DS #, DS? Diode Select. This selects the laser diode source for the currently
selected objective. Each diode (in a dual diode system) is focused
at a different plane. This will help the focusing process when a
specific objective may have a different focal plane than the other.
A “0” will enable diode 1 only, and a “1” will enable diode 2 only.
A “?” will return the current diode selection. Default value is “0”.
EC #, EC? Echo. A “1” turns communication echoing on and a “0” turns it
off. A “?” will return the current state.
