Command: STOPBITS (not supported in TG-1000)
Shortcut:
SB
Format:
[Addr#]STOPBITS X=n
Function:
Sets the number of stop bits,
n
, to be used for RS232 serial communication. The default
is one (1) stop bit; the other option is two (2) stop bits. Use the
SAVESET Z
command
to retain the new stop bit setting after power off. Not supported in TG-1000.
Command: TTL
(only partly implemented in TG-1000)
Format:
[Addr#]TTL [X=IN0_mode] [Y=OUT0_mode] [Z=aux_IO_state]
[F=OUT0_polarity] [R=aux_IO_mask] [T=aux_IO_mode]
Function:
The MS2000 controller has a buffered TTL input (
IN0
) and output (
OUT0
) port as well as
several unbuffered I/O ports. The signals
IN0
and
OUT0
are found on the board
connector SV1 pin1 and 2 respectively. On many controllers these signals are connected
to the IN and OUT BNC connectors on the back of the controller. The
IN0_mode
and
OUT0_mode
parameters set with this command determine the character of the I/O pins.
It’s a
Card-Addressed command.
IN0_mode
:
0
- turns off TTL IN0 controlled functions; TTL interrupt DISABLED.
1
– TTL IN0 initiates a Move-to-Next-Position of the stored positions in the Ring Buffer
pointed to by the
buffer_pointer
. When the
buffer_pointer
reaches a value equal to the
number of saved positions, it resets to the first position, allowing cyclic repetitions to
the saved locations. See RBMODE and LOAD command.
2
- TTL IN0 repeats most recent relative move (See
MOVREL
) For example, begin a
session by issuing the command
MOVREL X=0 Y=0 Z=0.5
, and each subsequent
move to Next Position will cause the Z axis to move 0.05 micron. This function can be
used for repetitive relative moves of any axis or combination of axes. You may directly
set the
dZ
value with the
ZS
command’s X parameter.
3
– TTL IN0 initiates an autofocus operation on systems with autofocus installed.
4
– enables TTL IN0 controlled Z-stacks. (See
ZS
command).
5
– enables TTL IN0-started position reporting via the serial interface. Information is
asynchronously sent out the serial interface every
report_time
interval, where
report_time
is set with the RT command. Data returned in the serial stream are the
elapsed time in milliseconds since the TTL trigger, followed by the position of each axis
enable by the
axis_byte
. On TRACKING systems, the PMT sum signal is also reported.
Reporting is toggled on and off by the TTL input pulse.
