PRECAUTIONS 3.1 On Operation Failure to comply with any of the following precautions may damage this device. • DO NOT CONNECT OR DISCONNECT THE CABLES BETWEEN THE CONTROLLER AND THE MECHANICAL UNITS WHILE POWER IS ON. Please allow at least 20 seconds after turning the unit off before disconnecting the mechanical units.
Instrument Co. This post, along with posts of other dimensions, as well as post holders and bases, are available from most laboratory equipment suppliers. A SmartShutter can also be mounted on a Sutter Instrument Co. Filter Wheel with a special enclosure, as well as with other Sutter Instrument Co. products, such as the Lambda LS, Lambda DG-4, Lambda DG-5, and various Lambda 10 series Filter Wheel controllers.
5. UNPACKING The Lambda SC and associated hardware comes packed in a single carton. The following is a list of the components found there. If you believe that any of these components are missing or show obvious signs of damage from shipping, please contact the factory. ...
6. FIRST TIME USE 6.1 Some Basic Information The Lambda SC is a microprocessor-controlled, high-speed shutter controller designed for microscopy and other applications that require rapid and accurate wavelength switching. The Lambda SC controller can control one SmartShutter and features a USB input for remote control.
6.2 Line Power (Mains) The power cord provided with the Lambda SC connects to the Power Entry Module located on the back of the unit (see diagram below). This Module also includes the Line Fuse and Power Switch. Figure 6-1. Lambda SC cabinet (rear view) Figure 6-2.
Utility software after having installed the USB device driver. Additionally, the open/closed state of the SmartShutter can be controlled by connecting a triggering signal to the TTL Input connector on the rear of the Lambda SC box. 6.5 Make It Go 1.
SMART SHUTTER Smart Shutter is a lightweight motor-driven aluminum vane under microprocessor control. Because of the microprocessor control, the motion of the vane can be tailored for different roles. The vane starts and stops under motor control, eliminating the sharp jolt typical of other fast shutters.
In this mode the user selects the extent to which the shutter opens. When used with the Sutter Instrument light guide system (LLG), this allows the light output from the light guide to be attenuated without changing its wavelength or spatial distribution.
SmartShutter When a 35 mm is to be mounted to a 32 mm Lambda 10 filter wheel, a special SmartShutter adapter threads into the filter wheel T-mount and the mounts on this piece. SmartShutter The 35 mm has a receptacle for the flange on the end of this T-mount tube and SmartShutter this allows the to mount to the flange on the end of the tube in many different...
the number of steps selected. For a complete opening of 144 steps, the time to open and the time to close will each be about 38 msec. The time required will be approximately proportional to the number of steps, or about 2.6 msec per 10 steps. 7.3.3 Repetition Rates and Duty Cycle Operation does not require over-driving the motor windings, so the motor windings are not damaged by frequent opening and closing over long time periods.
8. CONTROLLER 8.1 Principles of Operation The Lambda SC controller is operated remotely from a computer through the USB port. Remote operation allows the user to select: Shutter position Shutter mode The remainder of this chapter provides a detailed description of the controller’s rear panel connectors and front panel controls.
NOTE: The RS-232 serial port is absent on early versions of the Lambda SC controller. If you have a version of the Lambda SC that does not have the serial port, and you would like to have it added, please contact Sutter Instrument Co. to arrange for an upgrade. 8.2.4 TTL Input and Output Two BNC receptacles are provided for TTL control of the connected SmartShutter.
Lambda SC controller. If you have a version of the Lambda SC that does not have the switch, and you would like to have it added, please contact Sutter Instrument Co. to arrange for an upgrade.
9. MANUAL CONTROL Manual control of the Lambda SC and the attached SmartShutter can be achieved by one of two means: Toggle switch on the front panel of the Lambda SC cabinet. A foot switch (or other switching device) attached to the TTL IN receptacle on the rear of the Lambda SC cabinet.
10. REMOTE CONTROL The remote control of the Lambda SC can be achieved by issuing commands on a remote computer and transmitting them to the Lambda SC over a USB (Universal Serial Bus) or RS- 232 serial connection. This chapter provides a description of these commands and how they are used.

The microprocessor in the controller is programmed to distinguish between these two types of Input Commands based on the bit pattern of the Command and will respond accordingly. These two types of Commands are discussed in more detail in the following sections. 10.3 Shutter Commands Shutter commands are described in the following table, along with the decimal, hexadecimal and binary values that encode them.
10.3.5 Neutral Density Mode Shutter SmartShutter Sets the mode of the specified shutter to NEUTRAL DENSITY ( only). The command ends with a second byte, which contains a value of 1 through 144 indicating the number of microsteps. 10.4 Special Commands Special commands are those that are not specifically related to the control of shutters.

(Decimal, hexadecimal, & binary) Lead-in byte for 4/(5) Lead-in byte for all Lambda SC-specific Lambda SC special commands (TTL IN, TTL OUT, Special commands Timers, and Free Run). This lead-in byte is 11111010 (1 byte) expressed only once in the status return data structure, and this is where it occurs.
10.4.4 Transfer to On Line This command is the equivalent to pressing the ON LINE key on the Lambda SC’s keypad. If the controller is in local mode (i.e., it is off line), this command will cause the controller to go on line (the opposite of local mode), enabling it to respond to other commands from the remote computer.
10.4.12 TTL IN Falling Edge Triggers SmartShutter to Toggle On the falling edge of the signal coming in on TTL IN, the shutter opens if closed or closes if open (toggles its state). 10.4.13 TTL OUT Synch Signal Disabled Disables the synchronization signal on TTL OUT. 10.4.14 Opening Shutter Sets TTL OUT to High When the shutter goes to the open state, the synchronization signal on TTL OUT goes high.
10.4.23 Get Controller Type and Configuration This command is used to obtain information about the controller as to its model and configuration. The following table shows the type of information returned when issuing this command. Table 10-7. "Get Controller Type and Configuration" command return codes and data Configuration Total Description...
SmartShutter 10.6 Movement Errors: Causes and Solutions The SmartShutter is optimized for the fast shutter action. One element of the SmartShutter’s overall design that contributes to its superior performance is the acceleration and deceleration profiles that are pre-programmed into the microprocessor commanding the motor.
10.7.1 Preparing the Command Byte All remote control command codes for the Lambda SC require no more than one byte (8 bits) of storage for each command. If using a programming language that make a distinction between unsigned and signed bytes, always select unsigned only. “Unsigned” means that only positive numbers can be stored, whereas “signed”...
NOTE: The RS-232 serial port is absent on early versions of the Lambda SC controller. If you have a version of the Lambda SC that does not have the serial port, and you would like to have it added, please contact Sutter Instrument Co. to arrange for an upgrade. 11.1 Connecting to the Serial Port The serial interface connector on the back of the Lambda SC controller cabinet is a DB-9 female connector.
Communication for the serial port requires the following settings: Baud rate 9600 Data bits Parity none Stop bits Flow Control: none No hardware control lines are connected. You must either set the communication mode so that these lines are ignored or provide connections that will satisfy the mode of communication that you use.
12. REMOTE CONTROL: USB PORT The Lambda SC can communicate with the computer via the Universal Serial Bus (USB) port instead of the SERIAL (RS-232) port whenever it is connected to the remote computer with a USB cable and the appropriate USB device drivers are installed. The remote computer must be equipped with the necessary USB hardware and its operating system must be properly configured to recognize and work with the USB interface.
shape is the one that connects the USB device. The device connector is shown in the following figure. Figure 12-1 -- The USB cable device connector. 3. And the receptacle in the rear of the Lambda SC into which the “device” connector of the USB cable connects is shown in the following figure.
Windows may also automatically install the appropriate drivers if another Sutter Instrument Company instrument with a USB interface (such as a Lambda 10-3, a Lambda 10-B, an MPC-200, or even another Lambda SC) is already connected and configured with your computer.
Do not be concerned that Windows is unable to find a Microsoft digital signature for the Lambda SC as shown in the previous figure. Simply press the “Yes” button to continue to the next step. The next figure shows the dialog box that Windows displays when it is ready ask you for the location of the Lambda SC USB device drivers.
Figure 12-8 -- Browsing for the driver file needed. Once the requested files are located, the Windows USB device installer will complete. Note that you may need to cycle through the two dialogs shown in the last two figures before the requested file is located and installed. This completes the description for installing the Lambda SC as a USB device connected to a Windows system.
testing is to install and run on the remote computer the USB Test and Demo program for the Lambda 10-series (a Windows program). This program is called “USBTest”, and once installed, can be used to determine if the remote computer is able to communicate with the Lambda SC as a USB device.

5. If the uninstall process completed, the FTD2XX entry in the Add/Remove list should now be gone. Note that although the above procedure will remove the Lambda SC USB device driver from active use, not all related files on your system are actually deleted. Should you decide to reinstall the USB driver for the Lambda SC after having gone through the uninstall process, Windows will most likely be able to locate the necessary USB driver file on your system during the installation process, without requiring you to supply the disk containing the...
13. REMOTE CONTROL: LOGIC LEVEL (TTL) INPUT FOR SHUTTER CONTROL In addition to the control of the shutter via the USB port and the serial port, the direct TTL logic input can also control the shutter. However, input must be selected and configured for the mode desired.

14. PAIRED SHUTTERS FOR SHORT EXPOSURE TIMES The coordinated movement of two shutters in series in the optical path can be configured to produce shorter exposure times than is possible with a single shutter. A single shutter will require about 8 msec with the shutter completely open before the shutter blade can start covering the aperture.

programmed to be normally open at power on and to trigger on the falling edge of the TTL signal. This can be done using the Lambda SC utility. LAMBDA SC OPERATION MANUAL – REV. 1.14C (20190606)
15. MAINTENANCE Routine cleaning of the Lambda SC system is required to prevent excessive dust accumulations – wipe all exterior surfaces with a dry, soft, cotton cloth. All retaining rings should be inspected occasionally to be certain that they are seated into the filter holders and cups.
APPENDIX A. STEPPING MOTOR OPERATION Stepping motors are not as familiar to most people as the common DC motor, but there are some similarities. The DC motor consists of an armature, an electromagnet mounted on a rotating shaft, which is located inside a permanent magnet. Current is supplied to the electromagnet through brushes that rub on contacts on the armature.

control electronics, the resulting move may differ from that commanded by the control electronics. For instance, if enough external force is applied, the motor shaft may be rotated even though the command signal has not changed. For small rotations (less than 3.6 degrees), the motor shaft will return to the correct position if the force is removed.
Replace the active fuse with the spare and re-install the fuse holder and power cord. If the controller fails to power up with the new fuse installed, call Sutter Instrument technical support personnel for assistance.
SMART APPENDIX C. MOUNTING A SHUTTER IN A LAMBDA LS Smart The one-inch stand-alone version of the Shutter can be mounted inside current versions of the Lambda LS. A male-to-male c-mount adapter is used to couple the Smart Shutter to the c-mount block inside the Lambda LS. Stacking c-mount extension tubes Smart are threaded into the other side of the Shutter to provide an enclosed light path from...
