Introduction

1.11.1

IntroductionIntroduction

The Lambda 10-3 is a filter wheel and shutter control system designed for the rapid change and aperture control of wavelength, and is comprised of two subsystems: 1) a controller, and

2) a combination of filter wheels and shutters that are placed in the optical pathway(s) of your existing experimental setup. The controller is microprocessor-controlled with capability of delivering power and control signals to one to two filter wheels, and optionally to one to two integrated shutters. Each integrated shutter may be a SmartShutter or a conventional shutter. Each of the two filter wheel/shutter combinations may also consist of a standalone filter wheel and a standalone SmartShutter. A third standalone filter wheel (without integrated shutter) is also supported. In the latest revision of the Lambda 10-3, the third standalone filter wheel may be replaced with a standalone SmartShutter.

1.2 General Description

General Description

1.21.2

General DescriptionGeneral Description

The Lambda 10-3 is a microprocessor controlled, high-speed filter wheel system designed for microscopy and other applications that require rapid and accurate wavelength switching. The Lambda 10-3 controller can control two filter wheels each with a high-speed shutter and a third filter wheel without a shutter, and features both USB and serial RS-232 input for remote control.

The controller is designed around an embedded microcontroller, which automatically determines the equipment installed. The electronics for controlling a shutter are already installed, even if you did not order that option. If you add a shutter later, there are no additional electronics to buy, although you may need to configure the circuit board for the size of shutter if you wish to install a UNIBLITZ shutter.

The controller can run up to three filter wheels, up to two of which can be equipped with a shutter, or different combinations of filter wheels and standalone smart shutters, all under remote control through a USB or serial input using the same simple protocol as the previous Lambda 10- 2 controller with only minor differences. The USB and the serial RS-232 interfaces use the exact same remote control command set. Some important considerations

about using a combination of input sources (e.g., the keypad and the Serial port) are discussed in the Remote Control section of this manual.

The following instructions are meant to help you set up the Lambda 10-3 and become familiar with the manual mode of filter selection. Other sections of this manual contain detailed discussions on the functionality of the controller, how filters are installed, and setting up remote control communications.

The LAMBDA SmartShutter

LAMBDA SmartShutter is a microprocessor controlled, high-speed shutter designed for

LAMBDA SmartShutter LAMBDA SmartShutter microscopy and other applications that require a shutter function. The Lambda 10-3 controller can control two SmartShutters. Shutters are commonly used to turn off a light source in order to prevent photo bleaching or other photo damage. In addition, they may be used to select between multiple light sources or light paths, such as transmitted light versus fluorescence excitation. SmartShutters, in particular, have the ability to be placed into one of several modes. These modes determine the way the actual shutter action works: Fast Mode, Soft Mode, and Neutral Density Mode. Fast Mode provides for the fastest open/close action of the shutter. Soft Mode, is slightly slower than Fast Mode, and provides for a somewhat gradual open/close action, as well as being quieter. Neutral Density Mode allows for the control of the aperture of the open state of the shutter – between 1 and 144 microsteps may be selected for the Neutral Density Mode. Neutral Density Mode also provides for the control of light intensity without affecting the wavelength.

The primary use of the shutter is as an accessory to the Lambda 10 series of filter wheels, but it is also used as a stand-alone piece for the transmitted light arm of inverted microscopes. The electro-mechanical shutters actuated by solenoids have been used by most optical manufacturers for decades, and have some outstanding features. They act quickly, they can be driven by simple electronics, and the package is quite thin. However, these units are prone to frequent failures and usually cannot be repaired. There is effectively no warranty from the manufacturer for the end user. Although they can produce short bursts of operation at 30 Hertz, they will overheat and fail quickly if this rate of opening is maintained. These shutters also produce a good deal of vibration and audible noise.

When a Lambda 10-3 Filter Wheel system is purchased, its configuration may include one filter wheel, with or without a shutter. If the Lambda 10-3 system is purchased with a 10position 25mm (1-inch) filter wheel, you may wish to exchange the filter wheel with a 10position 32mm or a 5-position 50mm filter wheel. If the filter wheel being replaced is a 10position 32mm filter wheel equipped with a 35mm shutter (UNIBLITZ® or SmartShutter),

SmartShutterSmartShutter

The SmartShutter 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.

Step Motor Based Shutter Advantages

1.4.11.4.1

Step Motor Based Shutter AdvantagesStep Motor Based Shutter Advantages

The new step motor-based shutter is made from a handful of parts, any of which can be replaced if it fails. The speed of opening and closing of the shutter is practically the same as the traditional shutters, and the mechanism is more robust. The shutter blade is stopped by action of the motor rather than by mechanical stops that might fail. Because the motion profile of the shutter is controlled by a microprocessor, the motion can be optimized for speed or for smoothness. The microprocessor-based controller also offers the potential for a very adaptable controller, which could include additional functions and modes of operation. If the electronics fail, the motor can be disconnected and the blade set open or closed by hand. Operation does not require over-driving the windings, so it can maintain operation at up to 40 Hz continuously. The unit can operate on modest voltages, which are typically available in the Lambda 10 series controllers. The package size is comparable to the traditional shutters and can be customized when needed.

Another advantage of step motor-based shutter is the ability to control the aperture of shutter blade in its opened state. This mode is called Neutral Density and is used to control the intensity of the light coming through the opened shutter without affecting the light’s wavelength. The neutral density aperture size of the shutter is determined by the number of microsteps (1 through 144) specified for the motor to open the shutter.

The following instructions describe how to set up the Lambda SmartShutter and selecting filters in manual mode. More detailed discussions on the controller functions, installing filters, and remote communications are found in other sections of this manual.

ModesModes

The Lambda 10-3 supports three modes of operation for the SmartShutter.



Fast Mode:

In the fast mode the motion is optimized for the fastest open and close times,

both of which will be about 8 msec.



Soft Mode:

The soft mode offers even less vibration at the expense of slower open and

close times.

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)



Neutral Density Mode:

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. The value for opening can be selected in steps from 1 (no opening) to 144 (complete opening).

The new step motor-based SmartShutter is made from a handful of parts, any of which can

be replaced for service. The SmartShutter can open or close in about 8 msec...., and the

mechanism is robust. The shutter blade is stopped by action of the motor rather than by mechanical stops that might fail. Because the motion profile of the shutter is controlled by a microprocessor, the motion can be optimized for speed or for smoothness. The microprocessor-based controller also offers additional functions and modes of operation. If the electronics fail, the motor can be disconnected and the blade set open or closed by hand.

1.4.3.1 Mounting

When a 25 mm SmartShutter is to be mounted to a Lambda 10 filter wheel, a special version of the SmartShutter is supplied which will attach directly to the slide-in filter housing. The C-mount threads in the SmartShutter housing will accept the standard Sutter microscope adapters.

When a 35 mm SmartShutter is mounted to a 32 mm Lambda 10 series filter wheel, a special adapter threads into the filter wheel T-mount, on to which the SmartShutter is mounted. The 35 mm SmartShutter has a receptacle for the flange on the end of this T-mount tube and this allows the SmartShutter to mount to the flange on the end of the tube in many different orientations. On the other side of the SmartShutter a similar rotating mount accepts an adapter that is used to couple to our standard microscope adapters. It is possible to install a T-mount instead, if desired.

1.4.3.2 Opening and Closing Times

The SmartShutter has a typical time to open of 8 milliseconds, from the point a complete command or TTL signal is received. The time to close is also eight milliseconds. This is true for both the 25 mm and the 35 mm versions operating in the fast mode. Note that the controller will not accept new commands or TTL pulses in the FAST mode for about 12 msec after a command has been received. The additional time is required for display changes and other overhead.

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

Figure 1-8. SmartShutter timing.

The timing of a

SmartShutter is shown in the figure above. The bottom trace is a TTL signal,

the middle trace is a 25 mm SmartShutter, and the upper trace is a 35 mm SmartShutter.

Operation is slower in the ND (Neutral Density) and SOFT modes. In the SOFT mode, the SmartShutter has a typical time to open of 60 msec. from the point a complete command or TTL signal is received. The time to close is also 60 msec. This is true for both the 25 mm and the 35 mm versions. In the ND mode, the time to open and the time to close will depend on 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.

1.4.3.3 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. 25 mm (one inch) versions can usually operate well at up to 20 Hz. 35 mm versions can usually operate well at up to 15 Hz. These shutters may be operated at higher rates up to 40 Hz, but there will normally be specific frequencies in the higher ranges that will produce errors in motion of the shutter blade. This is the result of resonances in the mechanical and electrical systems.

If the duty cycle is substantially different from 50%, errors in movement may occur at lower frequencies. At 40 Hz, the cycle time is 25 msec., with 12.5 msec. between open and close

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

commands. This is close to the absolute minimum time in either the open or closed state. If you attempt to reduce the time in either state below 12 msec, the controller will not start to change the shutter state until the 12-msec minimum period is over.

1.7.1 Stepping Motor Operation

Stepping Motor Operation

1.7.11.7.1

Stepping Motor OperationStepping 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. When the electromagnet is energized, the armature rotates to align the poles of the electromagnet with the opposite poles of the permanent magnet. Of course, before this can occur, the rotation of the armature changes the contact plates rubbing on the brushes so that the current is reversed. This causes the poles of the electromagnet to reverse, establishing a force for continued rotation. This switching action is called commutation.

In stepping motors, the rotating element, called a rotor, is generally a permanent magnet while the fixed element, the stator, is the electromagnet. The key difference between stepping motors and DC motors, however, is the method of commutation. The DC motor commutates automatically as it rotates. Thus, the timing of the commutation is determined by the speed of rotation, which may vary with the load or applied power. The commutation of the stepping motor is set by external electronics, forcing the motor to rotate at a predetermined rate. If the load is such that the motor does not have the force to produce the correct rate of rotation, the rotation will become erratic and may even reverse.

The force exerted between two magnet poles is proportional to the square of the distance between the poles. A motor with a single electromagnet and only two poles would exhibit considerable loss of power when the distance between the poles of the permanent magnet and the electromagnet was greatest. It is understandable that, in most practical DC motors, the armature has more than 2 poles. This allows the commutation to occur over a smaller angle of rotation, so that the active poles can always be relatively close to the poles of the permanent magnet.

Stepping motors are also made with multiple poles on both the rotor and stator; the exact arrangement determines the number of steps per revolution. The motor used in the Lambda 10-3 has 200 steps per revolution (1.8 degrees per step). There are usually two windings in the stator, and reversing the current on one of the windings produces a single step of rotation. Reversing the current on the second winding will then produce another step. If the first winding is then reversed again, returning to its original value, a third step will result. Finally, reversing the second winding, so that both windings are back to their original state, will produce a fourth step. This pattern may then be repeated to continue rotation in the same direction. Reversing the sequence produces steps of rotation in the opposite direction.

The rate and distance of rotation is determined by the rate and number of commutation steps. As long as the current is held constant in both windings, the rotor will not rotate. This makes the stepping motor ideal for producing fast start and stop movements. Some limitations should be considered. Given that there are only 4 states of the control electronics (2 polarities for each of the 2 windings) but 200 steps per revolution, it follows that, for each of these 4 states, there are 50 possible rotary positions. In order to establish the absolute

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

position an external sensor must be added. Absolute position only needs to be determined once so long as the subsequent moves occur without errors.

Correct operation of stepping motors, which is outlined above, is not always obtained. If the motor lacks the torque to accelerate and decelerate the load at the rate indicated by the 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. For larger rotations, the shaft will stop at the nearest of the 50 correct positions for that command signal when the external force is removed.

2.2.12.2.1

VibrationsVibrations

The Lambda 10-3 filter wheel system was designed to produce fast filter changes with a minimum of vibration. The microprocessor controls the trajectory of each move using microsteps with programmed acceleration and deceleration profiles. The result is a system so smooth that customers using the Lambda 10-3 for the first time have called to report that their wheel isn’t turning simply because they could not hear or feel anything.

Although the Lambda 10-3 is smooth and quiet, even the slightest vibration can produce problems for the electrophysiologist. Vibration can come from several sources. The most pronounced effects normally come from the high-speed shutter, if that option has been included. The shutter produces a very sharp impulse which is best avoided by finding another way of turning the light on and off such as turning to a blanked filter position. When the motor accelerates and decelerates the filter wheel rapidly, the torque applied tends to turn the motor and the Lambda housing in the opposite direction. If the housing is not firmly attached, this may appear as vibration that increases with the selected speed and the weight of filters loaded. This is not usually a problem if the wheel is firmly mounted to a good solid surface.

Stepping motor-based systems can produce considerable vibration and noise if the rate at which steps are taken excites a system resonance. This problem is greatly reduced by decreasing the step size with microstepping. Even when microstepping is used, it is possible to produce vibration by selecting a speed that is not optimal or by starting a new move within a few milliseconds of the end of the previous move. For example, with only 2 typical filters loaded speed 1 should give a very smooth move that stops with little vibration. Speed 2, 3, and 7 may all produce more vibration at the end of a move with this load even though they are slower speeds.

At a minimum, we recommend that the Lambda 10-3 should be firmly mounted to a solid surface by the support stand, which is included with each unit. Do not depend on the optical coupling between the microscope and the Lambda 10-3 to support and stabilize the Lambda 10-3. This configuration will be adequate in many cases. If there is still too much vibration,

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

the wheel may be mounted using the support stand, but with an air gap between the Lambda 10-3 and the microscope.

The best cure for vibration is isolation. One simple approach is to mount the filter wheel to a wall or a separate table. If the microscope is on an air table, be aware that the microscope might drift relative to a filter wheel mounted on a separate, stable surface. In such cases, it may be better to couple the Lambda 10-3 to the microscope with a flexible light guide. Contact Sutter Instrument for detail of our light-guide adapter system.

Installing the Filter WheelInstalling the Filter Wheel

If you have not yet mounted the filter wheel on the support hardware, please refer to the FIRST TIME USE chapter of this manual for instructions. Now move the mounted filter wheel to the approximate final location and adjust the filter wheel to the desired height. The filter wheel can be mounted on the posts in either orientation (optical port up or down), as required. The filter wheel can now be interfaced with other instruments (e.g., a microscope and a light source) using an appropriate adapter (Figure 2-1). If you need to purchase an adapter or require a custom adapter for your experimental setup, please contact the Technical Support staff at Sutter Instrument Company by phone (415 883-0128) or by E-mail (info@sutter.com).

If a heavy light source is to be used (such as a vapor lamp with integral igniter) it should have its own separate support system.

If your filter wheel has a shutter, the side of the filter wheel on which the shutter is installed (the “motor side” as shown in Figure 1-2 and Figure 1-3) would typically be mounted toward the light source. Placing the shutter between the lamp and filters limits the amount of heat and light to which the filters are exposed and increases the filters’ useful lifetime.

Filter Cups and Filter HoldersFilter Cups and Filter Holders

At each filter position on the filter wheel is a filter cup assembly to hold one filter. The Lambda 10-3 25-mm filter wheel also comes with two removable filter holders that can be placed into the optical pathway to accommodate “fixed” filters, such as neutral density filters. The style of the filter holder will either be “drop in” if no shutter is installed (Item 6 in Figure 1-1), or “slide in” if a shutter is installed (Item 6 in Figure 1-2).

There are at least two components installed into each filter cup or holder before the Lambda 10-3 is shipped: a threaded retaining ring to secure the filter into the cup (or holder), and a spacer ring. In all but one of the filter cups, and in one of the filter holders, there will also be a blanking disc. Figure 2-4 depicts these items using the drop-in filter holder as an example.

Installation of Filters into Filter HoldersInstallation of Filters into Filter Holders

Installation of filters into the filter holders requires care and patience to avoid damaging the threads as well as the filters. The following procedures describe this process and should be practiced with a drop-in (or slide-in) filter holder before attempting to load filters into the filter cups.

Figure 2-5. Changing filters in the Slide-In Filter Holder.

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

Figure 2-6. Removing the retaining ring.

The threaded retaining ring has two notches cut into it, 180 degrees apart. Place the notched end of the brass spanner wrench (Figure 2-6, right) into the notches on the retaining ring and carefully turn it counter-clockwise to unscrew it.

Once the retaining ring is removed, the spacer (and blank, if present) should be easily removed. You should become familiar with the assembly of this retaining system. In particular, you should develop a feel for turning the retaining ring without pushing down on the driver or wrench. This is important because if you forcefully push on the filter holder while you are trying to load a filter, you run the risk of scratching the filter if the tool slips out of place!

Figure 2-7. Assembly order of filter holder parts.

Place the desired filter into the filter holder, first. With some 1” filters extra care must be taken to avoid getting the filters jammed at an angle.

Next, install the spacer ring into the filter holder. Unless the filter thickness precludes the use of the spacer ring (see Figure 2-6 and Figure 2-7), always install the spacer. This helps to

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

provide maximum separation between the filter surface and end of the tool that is used to turn the retaining ring.

Finally, install the threaded retaining ring. DO NOT OVER TIGHTEN THE RETAINING RING! It need only be tightened until it is firmly seated.

Installation of Filters into Filter CupsInstallation of Filters into Filter Cups

Loading filters into the filter cups on the filter wheel follows the same procedure as described above for loading filters into filter holders. There is, however, the additional complication of working through the filter wheel housing. To gain access to the filter cups on the wheel, unscrew the access plug from the loading port on the motor housing (i.e., the motor side of the filter wheel). A large coin or other suitable implement can be used to remove the plug. Once removed, the retaining ring in the underlying filter cup is accessible through that port.

To align the filter position you wish to load with the loading port, it is easiest to use the controller to identify and position the filter cups. To begin, connect the Filter Wheel to the controller (see the FIRST TIME USE chapter for a brief description of the principles of operation). When you first turn on the controller, the Filter Wheel will “HOME” itself, aligning the “0” filter position with the Optical Port and filter position #5 with the Loading Port. The filter currently in the Loading Port is five positions removed from the one indicated by the controller display (i.e., the one at the OPTICAL PORT). This relationship between the filter position indicated by the controller and the filter position at the LOADING PORT is illustrated in Figure 2-8.

After identifying and positioning the filter cup to be loaded, it is advisable to turn off the controller before removing the retaining ring from the filter cup. Follow the procedures described above for installation of filters into filter holders.

After loading the filter(s), check each newly loaded filter position to make sure that the retaining ring is not projecting above the top edge of the filter cup then replace the loading port plug.

Another potential complication of loading filters into the filter cups can occur if the retaining ring has been previously over-tightened. In this case, it is possible that the filter cup itself will begin to unscrew from the wheel as the retaining ring is turned. If this occurs, STOP!

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

Turn the spanner wrench so that the widest end is toward the filter cup and slip the wrench into the two notches in the edge of the cup. Then turn the wrench clockwise to screw the cup back into the slider. DO NOT push on the cup. Just screw it in until it seats firmly. It should then be possible to remove the retaining ring as described above without the cup turning.

It may appear that removal of the cover plate from the housing would facilitate loading filters. This is not the case! Removal of the cover plate will not give you access to the filter cup side of the wheel and may lead to misalignment of and damage to the Filter Wheel.

In most cases any given filter could be installed at any of the ten FILTER POSITIONS. However, some minor considerations may improve performance of the system. Adjacent FILTER POSITIONS will require less switching time. Therefore, if an experiment will require rapid switching between two filters they should be located next to one another. If separation by one or more occupied filter positions is necessary, keep in mind that there will be brief transitions through, possibly, undesirable wavelengths as light transmits through those intervening filter(s) unless a shutter is installed and programmed for use.

The controller will detect the SmartShutter, if installed. The controller will assume that there is a Uniblitz shutter if no SmartShutter is detected. If you have a Uniblitz shutter, an internal jumper, J21, on the Lambda 10-3 circuit board must be set to the correct position in order to ensure the best performance. This jumper is used to select operation of a Uniblitz 25 mm shutter or a Uniblitz 35 mm shutter. If you have no Uniblitz shutter than the jumper position is not significant. Position A is for 25 mm shutters and position B is for 32 mm shutters. You can check to see which position was selected by looking through the grill on the left side of the cabinet. If the jumper has been completely removed, 25 mm operation will also be obtained.

The one-inch stand-alone version of the SmartShutter can be mounted inside current versions of the Lambda LS. A male-to-male c-mount adapter is used to couple the SmartShutter to the c-mount block inside the Lambda LS. Stacking c-mount extension tubes are threaded into the other side of the SmartShutter to provide an enclosed light path from the SmartShutter to light port on the Lambda LS.

The stacking c-mount extensions that have been used in the past add 1 inch of length beyond the male threads. These pieces are stepped down in outside diameter so that they can slip inside a dovetail tube just as the lens tube does. The overall length of these tubes will be reduced by 0.070 inches so that two tubes stacked will fit between the SmartShutter and the external wall of the Lambda LS. These pieces will still be usable in conjunction with the dovetail tube to enclose the light path when no shutter or a Vincent shutter is installed. Until new parts are available, a single tube cut down by 0.14 inches can be stacked with a 1inch tube.

Since the Lambda LS does not have any inherent capability of controlling the SmartShutter, an externally positioned Lambda 10-3 (or another Lambda model capable of controlling a SmartShutter) can be used to control the SmartShutter. Additionally, the Lambda 10-3 can be used to control one or two filter wheels, one of which may be installed inside the Lambda LS, and another, which may be installed on the external part of the Lambda LS cabinet.

At power on the Lambda 10-3 will rotate the filter wheel to filter position 0. If the wheel does not rotate to this position as detected by a Hall-effect sensor, the display will indicate that there is an error. Once the wheel is properly initialized to Filter 0, it will move to Filter 9 and then back to Filter 0 to complete the power-on sequence. While in filter position 9 the microprocessor checks the optical sensor to determine if a full 10-position wheel is installed. If the optical switch indicates that it is not a 10-position wheel (such as a 50mm 5-position wheel), the controller will only execute moves to the optical port for filters 0 through 4.

Power Power

The control electronics for the filter changer are activated by the POWER switch (MAINS) on the back panel of the unit. Remember, when using an arc lamp with this system it is best to turn the lamp power supply on BEFORE turning on the Lambda 10-3. Arc lamp power supplies produce a high voltage lamp starting pulse that may interrupt normal operation of microprocessor-controlled devices or damage electronics.

When power is applied, the LAMBDA 10 determine the mechanical equipment attached to the controller. As part of this process, the filter wheel will rotate at a slow rate until sensors in the mechanical units signal that the “0” filter position is lined up with the optical port. The wheel will then make an additional move away from filter 0 and then back to filter 0. The controller currently automatically recognizes 3 different classes of filter wheels: standard 10-position, high-speed 4-position, and highcurrent 10 -position (32 mm). At power on, the Lambda 10-3 will rotate the filter wheel to filter position 0. If the wheel does not rotate to this position as detected by a Hall effect sensor, the display will indicate that there is an error. If the microprocessor detects that it is not a 10-position wheel, the controller will only execute moves to filter positions 0 through 3.

While the unit is going through these steps, the following screen is displayed:

The speed of the currently active filter wheel is set by, while at the Status screen, pressing MODE, pressing 2, followed by one of eight speeds (keys 0 through 7). The following screen is displayed after pressing MODE 2 from the Status screen or pressing 2 from MODE screen.

Speed 0 is the fastest speed and 7 is the slowest. Entering the selected speed under computer control is covered in a separate section.

The switching times (in milliseconds) for each of the 8 speeds is given in Table 4-1. Note that a 5-filter position move is the longest move on the 10-position filter wheel, since the controller will always rotate the correct direction to make the fastest change of position. For a given speed, the time for a move to a non-adjacent filter will take about 1.8, 2.5, 3.3 or 4 times as long as a move to an adjacent filter, depending on the number of filters to be skipped. The highest speed that can be used will depend on the weight of the filters mounted in the wheel. In a 25mm, 10-position filter wheel equipped with two typical filters and eight blocking disks, adjacent filters can be changed in less than 40 milliseconds with a speed setting of 1. A correspondingly-equipped 32mm wheel may require a lower speed.

Filter commands

Shutter commands

Special commands

These are commands used exclusively for controlling filter wheels.

These are commands used exclusively for controlling shutters (SmartShutters and/or Vincent shutters).

These are commands for the general control of the Lambda 10-3 controller, and are not specifically related to either filter wheels or shutters.

Most of the commands described in this chapter are ones that are sent from the computer to the Lambda 10-3. Some of these commands will cause the Lambda 10-3 to return certain special codes or one or more bytes of data. Some commands must be followed by one or more bytes containing parameters. For each byte sent to the Lambda 10-3, that same byte is echoed (transmitted) back to the remote computer as confirmation that the byte was received. The echoing back of command bytes in no way indicates validation of a command or parameter, but is rather an acknowledgement from the controller that the byte was received. When the Lambda 10-3 controller finishes performing the task associated with a command (or command followed by one or more parameter bytes), an ASCII carriage return (CR, 13 decimal, or 0D hexadecimal) is transmitted back to the host computer as an indication that function associated with the command has completed and that the controller is now ready for another command. This echoing back of bytes sent by the remote computer to the controller, and the return of an ASCII carriage return after a command’s task is complete is the same for the serial, USB, and parallel interfaces.

For Wheel C, a byte containing a value of 252 decimal (FC hexadecimal) must precede the command byte. The filter wheel speed is encoded in octal (base 8) using Bits 6, 5, & 4. The filter position is encoded in BCD (Binary Coded Decimal) using the least significant nibble (Bits 3, 2, 1, & 0).

Queries the controller as to its type and configuration.

Commands sent to the controller via the serial, USB, or parallel interface are structured in a one-byte (8-bit) signal. Some commands are followed by one or more bytes containing additional parameter information for the command. The 8 bits can be used to convey three types of commands.



Filter Commands.

Filter Commands. These commands select the desired filter position and switching speed.

Filter Commands.Filter Commands. The filter position and switching speed are each specified by the encoding of specific bits within the command byte.

1. The filter position is specified in the least significant 4 bits (nibble) of the byte (Bits 3,

2, 1, and 0), providing value range of 0 through 9. Because only 10 possible filter positions are encoded in these bits, they are effectively encoded in Binary Coded Decimal (BCD) format, leaving the values of 10 through 15 (decimal) available for use by Shutter and Special commands.

2. The filter switching speed is specified in the least significant 3 bits within the most

significant nibble of the byte (Bits 6, 5, & 4), providing a value range of 0 through 7. These bits are interpreted as the filter switching speed only if the bits in the lower nibble of the byte contain a value of 0 through 9, specifying the filter position as described previously

3. The filter wheel selection is specified in the most significant bit of the byte (Bit 7).

This bit is set to 0 to indicate the first (Wheel A) or the third (Wheel C), and is set to 1 to indicate the second wheel (Wheel B). When the third wheel (Wheel C) is indicated, a prefix byte is required before the filter wheel command byte, in order to indicate that the filter wheel command byte refers to Wheel C and not Wheel A.

5.2 Filter Wheel Commands

Filter Wheel Commands

5.25.2

Filter Wheel CommandsFilter Wheel Commands

A byte command sent to the controller that contains a value from 0 through 121 decimal (00 through 79 hexadecimal) is interpreted as a Filter Wheel Command. Within a Filter Wheel

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

Command byte, three parameters are encoded: Filter Wheel, Speed, and Position. The accommodation of these three parameters within a single byte is accomplished by breaking up the byte into three parts: two bit groups, and one single bit, as follows.



WHEEL BIT:

WHEEL BIT: Bit 7 is used to select the filter wheel to which the encoded command byte

WHEEL BIT: WHEEL BIT: applies. If Bit 7 is set to 0, either Wheel A or Wheel C is selected, and if set to 1, then Wheel B is selected. In order have Bit 7 apply to Wheel C (when the bit is set to 0), the entire encoded filter wheel command byte must be preceded by a byte containing the value of 252 decimal (FC hexadecimal, or 11111100 binary).



SPEED

SPEED BIT

SPEED SPEED

BIT GROUP:

GROUP: These 3 bits select the speed of movement used in advancing to the

BIT BIT

GROUP:GROUP: next filter. The speed group is treated as a three-place binary number whose equivalent decimal value, 0 through 7, correspond to the selected speed.



FILTER POSITION

FILTER POSITION BIT

FILTER POSITION FILTER POSITION

BIT GROUP:

GROUP: This group consists of all four bits within the lower

BIT BIT

GROUP:GROUP: nibble of the byte (the least significant 4 bits of the byte). These four bits select the desired filter (i.e., the filter wheel position). This group is treated as a four-place binary number, with the equivalent decimal values 0 through 9 corresponding to the selected filter position. These four bits can also be thought of as containing a BCD (Binary Coded Decimal) value, since BCD always use four bits to encode only decimal values 0 through 9. Values 10 through 15 decimal (A through F hexadecimal) in these four bits are currently undefined and should never occur. Binary codes with decimal values greater than 9 are ignored, unless the binary value (in conjunction with the SPEED GROUP bits) corresponds with the decimal equivalent of one of the Special Command Codes listed later in this chapter.

for Wheel A or C, and to 1 for Wheel B. All three sets of bits are combined into a single byte (8 bits) in order to construct the “filter command”. All eight bits of the filter command are then sent at once to the Lambda 10-3 controller over the chosen communication interface (serial, USB, or parallel). The following table shows a filter command is made up of the three sets of bits (Wheel, Speed, and Position).

0 and the entire filter wheel command byte 0 and the entire filter wheel command byte

In the previous table, “Decimal Group Values” are equivalent to the values of the desired Filter Wheel (always 0), Switching Speed (0 through 7) and Filter Position (0 through 9). Their hexadecimal and binary equivalents are shown as the “Hexadecimal Group Values” and “Binary Group Values”, respectively. These 8 bits are the raw data, then, that serve as a Filter Command to select the Filter Position and Switching Speed via the Lambda 10-3 controller’s serial and USB ports. The Wheel bit (Bit 7) is used to select the filter wheel: 0 for Wheel A or C, and 1 for Wheel B. When selecting Wheel C, the encoded filter wheel command byte must be preceded by a byte containing the value of 252 decimal (FC hexadecimal), and Bit 7 in the encoded wheel command byte must be set to 0. In summary, the controller will treat any byte it receives from the remote computer as a “filter command” if the byte’s least significant nibble contains a value of 0 through 9. If the received byte’s least significant nibble contains a decimal value of 10 through 15, then the controller treats the entire byte as a “special command” or “shutter command”.

When the 8-bit command is identified by the controller as one which is not a filter wheel command, the entire byte is then treated as either a “special” or “shutter” command. Shutter Commands are described in the following table, along with the decimal, hexadecimal and binary values that encode them. The paragraphs that follow the table describe these commands in more detail.

Special commands are those that are not specifically related to the control of filter wheels or shutters. They are used primarily for the control, and the obtaining of status, of the Lambda 10-3 controller. These commands make use of all eight bits of the command byte, and begin with the value of 204 (decimal) or CC (hexadecimal). The following table lists all of the Lambda 10-3’s special commands.

Batch Start and Batch EndBatch Start and Batch End

The Batch Start and Batch End commands are used to enclose a sequence of one to six bytes representing one to five filter wheel movement commands and shutter action commands. The commands in between the Batch Start and Batch End commands may consist of speed and position commands for filter wheels A, B and C (3 command bytes, plus a 4th byte for the Wheel C prefix), and action commands for shutters A and B (2 bytes). Each item requires one byte, except for Wheel C, which requires two bytes. Commands for all five mechanical devices may be specified, or any subset thereof. The Batch End command instructs the controller to go ahead and execute the commands received after the Batch Start command.

The Batch Transfer command is used to instruct the controller to collect the next four filter wheel movement and shutter action commands, and then once received, execute the four commands in quick succession. The Batch Transfer command was introduced with the Lambda 10-2, and is supported in the Lambda 10-3 as is for compatibility with applications already programmed with this functionality. Although there is no strict order for the four commands that follow the Batch Transfer command, the following order is the one for which the controller is optimized, yielding the best performance.

1. Shutter A: 170 (open), 171 (open conditionally), or 172 (close)

2. Shutter B: 186 (open), 187 (open conditionally), or 188 (close)

3. Wheel A: 0 (wheel bit = 0) + 0 thru 7 * 16 (speed) + 0 thru 9 (position)

4. Wheel B: 128 (wheel bit = 1) + 0 thru 7 * 16 (speed) + 0 thru 9 (position) NOTE: The Batch Transfer command does not support Wheel C, since Wheel C requires two bytes for its command. If you wish to use Wheel C within the context of a batch process, the Batch Begin and Batch End command sequence should be used instead (see Page 53).

NOTE: In Lambda 10-3s programmed with Rev. 1.21 (and later) of the firmware, the default remote control port, which becomes active when the ON LINE key is pressed (serial, USB, or parallel), can be established via a new menu that is accessible in LOCAL mode.

The Special Commands shown above can be sent to the controller via the serial RS-232 port or the USB (Universal Serial Bus) port. The protocol used to transmit these commands is as described above in this chapter. The features of the SmartShutter can be used even without proper software support of the various modes of operation. The fast, soft and neutral density modes can be selected from the keypad. When so selected, open and close commands and the TTL input will act in the selected fashion.

Remote Control Command ProgrammingRemote Control Command Programming

This section describes some suggested tips and techniques when writing programs on the remote control computer for communicating with the Lambda 10-3 via either the serial RS232 port or the USB (Universal Serial Bus) port. The following paragraphs and the code examples deal with remote control command programming in a general manner, abstracted from telecommunications medium. The discussions and examples are applicable to either the serial RS-232 port or the USB port. The programming specifics for either the serial or USB ports are covered in the respective chapters, following this chapter. The discussions and examples are also relatively platform independent. The code samples written in the C programming language, for example, are written in a relatively primitive form, and thus should be easily portable to any platform for which C support exists (Windows, UNIX, Linux, Macintosh OS, etc.). Should another programming language be desired to implement the examples, the gist of examples should be fairly easy to glean if they are viewed as pseudo code – the examples should be easy to port to C++, Java, Pascal, BASIC, and other high level languages, or even various forms of scripting languages.

5.6.1

5.6.1 Preparing the Command Byte

Preparing the Command Byte

5.6.15.6.1

Preparing the Command BytePreparing the Command Byte

All remote control command codes for the Lambda 10-3 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” means that either positive or negative values can be stored. An unsigned byte can hold 256 different positive values (0 through 255). A signed byte can store only 128 different positive values (0 through 127, and 127 different negative values (-1 through –127). In the C programming language, an unsigned byte type is expressed as “unsigned char” followed by the name of the variable, such as:

unsigned char command_byte;

…where “command_byte” is the name the programmer chooses to give the variable.

5.6.1.1 Encoding Filter Commands Into a Single Byte

Filter commands are encoded into specific bit groups of the command byte. As discussed earlier in this chapter, and as shown in the table titled “Filter Command Structure” (Table 5-4), there are actually three commands stored at the same time in the command byte. The filter wheel selector is stored in Bit 7 (the most significant bit (MSB)) of the command byte, allowing 2 values (0 and 1)¹. The filter wheel speed is stored in the next lower three bits (Bits 6, 5, and 4), allowing 8 different values (0 through 7). In addition, the filter selector is stored in the next lower four bits (least significant nibble, Bits 3, 2, 1, and 0). Of the 16 possible values that can be stored in the least significant nibble, only the first 10 (0 through 9) are used for the filter selector. Any value above 9 will invalidate the entire command byte as a “filter command”, making the value stored in the byte as whole as either a shutter, special, or undefined command.

Note: Bit 7 supports the selection of one of three filter wheels: 0 for Wheel A or C and 1 for Wheel B. When selecting Filter Wheel C, the filter wheel command byte must be preceded with a byte containing a value of 252 decimal (FC hexadecimal), and Bit 7 in the encoded filter wheel command byte must be set to 0.

5.6.2 Command Transmission Protocol

Command Transmission Protocol

5.6.25.6.2

Command Transmission ProtocolCommand Transmission Protocol

The Lambda 10-3 does not use any of the standard protocols commonly used for serial line or USB communications between computers or between a computer and a peripheral device. The Lambda 10-3 controller, however, does generate a primitive form of protocol of which control software running on the remote computer can, and should, make use. This protocol consists of two main components: “confirmation command echo” and “command completion indicator”. This command transmission protocol is used in the same manner for RS-232 serial port, USB, and parallel port connections.

5.6.2.1 Confirmation Command Echo

When the host computer sends a command to the Lambda 10-3, each byte received is immediately echoed back to the host computer. This echoing back of each sent byte is a confirmation that the byte has been received and will be acted upon shortly. A short period after the last byte of a command has been echoed back, the Lambda 10-3 sends a confirmation byte (described next) that indicates the operation associated with the command completed.

5.6.2.2 Command Completion Indicator

When the Lambda 10-3 completes the operation associated with the command it has just received, it transmits back to the host computer a byte value of 13 decimal (0D hexadecimal, 00001101 binary). This byte value corresponds to an ASCII carriage return (often abbreviated as “CR”).

The Lambda 10-3 microprocessor sets the serial RS-232C port, by default, as the input source upon startup and anytime the ON LINE key is pressed. An appropriate command from the remote computer through the serial port will automatically set that port as the active input source and the display on the controller will reflect that change on its bottom line. The serial port will remain active until an appropriate command is sent from a remote computer through the USB port or until the LOCAL key is pressed on the controller keypad.

There are, obviously, some basic differences in the physical connections and the modes by which serial and USB data are transmitted to the controller. The command code and return code structures are, however, for the most part, the same. The connection and command structure required to control the Lambda 10-3 via the Serial port are discussed in this chapter.

6.1 Connecting to the Serial Port

Connecting to the Serial Port

6.16.1

Connecting to the Serial PortConnecting to the Serial Port

The serial interface connector on the back of the Lambda 10-3 controller cabinet is a DB-9 female connector. The connections are arranged so that a standard DB-9 serial cable can be used to connect the controller to a PC serial port. The port operates on a minimal RS-232 protocol where only the signal ground and the two data lines (transmit and receive) are connected; the hardware control lines are not connected. This port is designed for connection to a standard computer serial port. It should not be connected to any other type of interface or device. The pin assignments for this connector are, as viewed from the back of the controller:

communication that you use. In Microsoft QuickBasic the communication channel may be opened with a statement such as:

OPEN "COM1:9600,N,8,1, CD0,CS0,DS0 " FOR RANDOM AS #1 LEN = 256

This sets COM1 to the correct mode for bi-directional communication through channel #1. The option list “CD0,CS0,DS0” causes QuickBasic to ignore the DCD, CTS and DSR control lines. Other variants of the BASIC programming language (implemented for the PC) will have a similar syntax for the above statement.

6.2 Input Command Set and Protocol

Input Command Set and Protocol

6.26.2

Input Command Set and ProtocolInput Command Set and Protocol

Input Commands to the controller via the serial port are structured and adhere to the same protocol as described in the REMOTE CONTROL chapter. The Filter, Shutter, and Special commands, as described in the REMOTE CONTROL chapter, all apply to the serial port interface. Each command consists of one byte (8-bits), and some commands are followed by one or more bytes as parameters. The command protocol is the same as described in Chapter 5 (EXTERNAL COMMAND CONTROL): As a command is sent to the controller, it is immediately echoed back to the computer, and when the controller has completed the task associated with the command it has just received, it sends an ASCII CR (carriage return) byte (13 decimal, 0D hexadecimal) to the computer.

Since the serial data stream format is a single byte, each command can be sent as an ASCII character. If you have used a communications the subsequent 8 bit command values may be sent using a

language open statement to establish serial

BASIC

PRINT #

command such as:

PRINT #1, CHR$(DATANUM);

…where #1 is the file number used in the open statement, and DATANUM is the value of the command to be sent. Note that the CHR$ function allows the actual number to be sent rather than the ASCII numbers of the characters that represent the number. Sending “;” disables the automatic addition of characters such as a linefeed or a space.

The Lambda 10-3 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. Of all the USB ports available on the remote computer, be they part of the computer itself or part of a USB hub, one port must be available for use with the Lambda 10-3.

The Lambda 10-3 microprocessor sets the SERIAL port, by default, as the input source upon startup and any time the ON LINE key is pressed. An appropriate command from the remote computer through the SERIAL port will automatically set that port as the active input source and the display on the controller will reflect that change on its bottom line. The SERIAL port remains active until an appropriate command is sent from a remote computer through the USB port or until the LOCAL key is pressed on the controller keypad.

Note that there are some basic differences in the physical connections and the modes by which USB and serial data are transmitted to the controller. The command code structures, however, are quite similar. The connection and command structure required to control the Lambda 10-3 via the USB port are discussed in this chapter.

Installation Steps

7.1.17.1.1

Installation StepsInstallation Steps

To install the Lambda 10-3 as a USB device on a remote computer running one of the abovelisted versions of the Microsoft Windows operating system, follow these steps.

1. Make sure that the Lambda 10-3 is plugged into a power source and that its power switch

is set to OFF.

2. Connect the “device” connector of the USB cable to the USB receptacle in the back of the

Lambda 10-3. Of the two connectors on the supplied USB cable, the one that is square in shape is the one that connects the USB device. The device connector is shown in Figure 7-1.

Figure 7-1. The USB cable device connector.

3. In addition, the receptacle in the rear of the Lambda 10-3 into which the “device”

connector of the USB cable connects is shown in the following figure.

Figure 7-2. The Lambda 10-3 USB receptacle.

4. Turn the power switch in the back of the Lambda 10-3 to ON.

5. Make sure the computer is powered up and the Windows operating system has fully

finished starting up. Plug in the other end of the USB cable (the “host” connector) to any of the unused USB ports on your computer. You can also use an unused port of a USB hub connected to your computer, provided that the driver/software for the hub has already been installed and the hub is functioning properly. The “host” USB receptacle and connector are rectangular, as shown in the following figures.

32-bit and 64-bit Versions of Windows: The standard USB device driver for the Lambda series is designed to work with 32-bit versions of the Windows operating systems listed above. The combined driver model (CDM) version of the driver must be used with all 64-bit editions of Windows (XP, Vista, and 7).

Windows Vista and 7: Because Windows Vista’s security architecture has been significantly enhanced over previous versions of Windows,

you will find that the installation process (described next) will frequently prompt you for permission to proceed to subsequent steps.

Once the USB “host” connector is inserted into the appropriate receptacle on the remote computer, the Windows operating system should immediately start the “new USB device” detection process. The following message box should appear on your screen:

Figure 7-5 New USB device detected message box.

The above message box will display for a period of time, possibly up to a couple of minutes, while Windows goes through the process of determining if it already has device driver information for this new device.

If the Lambda 10-3 USB device drivers have already been installed on this computer, then Windows will usually find them and automatically reactivate them. If the drivers had been previously installed and then removed (uninstalled), it is possible that Windows is still able to locate the drivers and automatically reinstall them. Windows may also automatically install the appropriate drivers if another Sutter Instrument Company instrument with a USB interface (such as a Lambda 10-B, a Lambda SC, an MPC-200, or even another Lambda 10-3) is already connected and configured with your computer. If this is the first time the Lambda 10-3 USB device drivers are being installed, it is then quite likely that Windows will display the dialog box shown in Figure 7-6.

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

Figure 7-6 -- Digital Signature dialog box.

Do not be concerned that Windows is unable to find a Microsoft digital signature for the Lambda 10-3 as shown in Figure 7-6. Simply press the “Yes” button to continue to the next step. Figure 7-7 shows the dialog box that Windows displays when it is ready ask you for the location of the Lambda 10-3 USB device drivers.

Figure 7-7 -- Specifying location of driver files.

In Figure 7-7, the dialog box displayed contains a combo box that contains a path to a location from which Windows remembered it had last copied a USB device driver. This may or may not be the path that currently contains the necessary files for the Lambda 10-3 USB interface installation. You have the following three choices for this dialog box:

1. Enter a path in the “Copy files from” combo box and then press OK.

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

2. Select from the memory list in the “Copy files from” combo box, by pressing the inverted

triangle to the right of the combo box, and then selecting and clicking on one of the items (if any) displayed in the pulldown list, and finally pressing OK.

3. Alternatively, clicking the Browse button displays another dialog that allows you to

navigate through your system’s drives and folders for the location containing the needed Lambda 10-3 USB device driver files. Once found, and you’ve returned to the previous dialog box, the path chosen will now be shown in the “Copy files from” combo box, whereupon clicking OK will continue the process by using the path chosen. The following figure shows the dialog that is displayed after the Browse button is clicked.

Figure 7-8 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 10-3 as a USB device connected to a Windows system.

Verifying USB Communication between Remote Computer and Lambda 10Verifying USB Communication between Remote Computer and Lambda 10

Once the Lambda 10-3 has been connected to the remote computer with the USB cable and the remote computer has had the necessary device drivers installed, you will probably want to test and verify that the remote computer is, in fact, communicating correctly with the Lambda 10-3 over its USB connection. Probably the most expedient method for doing this 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 10-3 as a USB device. The USBTest program is provided on a 3.5-inch HD floppy diskette or CD-ROM, shipped with the Lambda 10-3 or it can be downloaded from Sutter Instrument Co.’s web site (www.sutter.com). The files that make up the distribution of the USBTest program include the Setup program. Simply run this setup program to install USBTest on your system (Windows-based systems only.

The USB Test & Demo program can be downloaded from Sutter Instrument’s web site using the following link:

The USBTest program has only one screen, and appears as shown in the following figure.

Figure 7-9 USBTest main screen.

Once you have the program up and running and the screen in the previous figure is displayed, you can use the program to first identify whether or not one or more Lambda 10-3 units are installed as USB devices. This is accomplished by first clicking the Search button which causes USBTest to scan the USB for the device requested. The search criterion is dependent on which one of the three radio buttons following "Open by:" is selected: Description, Serial Number, or Dev #. The results of the search are displayed on the "Data Received:" text field: highlight the item displayed there ("Lambda 10-3", serial number, or device number) and then click on it to select it. The selected item is then automatically copied to the text field associated with the Search button. Finally, click the Open button to open the Lambda 10-3 USB device for communication. The text field associated with the Open button will be updated with a message indicating that the USB device has been successfully opened. To verify communications with the Lambda 10-3, click on different filter wheel radio buttons, at different speeds - you should be able to see and hear the filter wheel move.

The source code for the USBTest program is also available upon request. The source code consists of all source, resource, and library files, including all necessary project files for building the program with Microsoft Visual C++ (or Studio) Version 6.0. The program is

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

written in C and C++ and includes the use of the MFC (Microsoft Foundation Classes) library included with Microsoft Visual C++ (or Studio) Version 6.0. The USBTest program also makes use of a library called FTDIXXX .DLL that is freely available from FTDI, the manufacturer of the USB chip set used in the Lambda 10-3 and which gets installed on your system when the USB device driver for the Lambda 10-3 is installed. The FTDIXXX .DLL is “bound” to the USBTest program via two files that are included with the USBTest program source code: FTDIXXX.H, a C/C++ header file that gets included at compile time, and FTDIXXX.LIB, the FTDIXXX.DLL interface library file, which gets linked to the project at link time. All three files are freely downloadable from FTDI’s web site: (www.ftdichip.com).

Alternatively, a custom program can be written to verify the installation and for sending commands to the Lambda 10-3. Although providing the source code for an entire ready-torun program is beyond the scope of this manual, the following paragraphs describe the key elements such a custom program should have in order to identify, connect with, and transmit to the Lambda 10-3 as a USB device. Accompanying these paragraphs are listings containing snippets of code written in the C programming language that may prove of further use should it be desired to create a custom program. Note that the code examples assume that the FTDIXXX.LIB and FTDIXXX.H files described previously are being used. You may download these files directly from FTDI’s web site: www.ftdichip.com.

Uninstalling the USB Driver for the Lambda 10Uninstalling the USB Driver for the Lambda 10

Normally, the device drivers installed on your system that enable communications with the Lambda 10-3 over the USB, once installed, do not need removing from your system. If you do need to remove the USB drivers installed specifically for the Lambda 10-3 (e.g., the Lambda 10-3 will no longer be used with the system in question), the following steps can be followed for Windows 98, ME, 2000, or XP.

1. Open the

opened in which a list of software that is installed on your system is displayed.

3. Select the line that has "FTD2XX Uninstaller" as the description, and click the “Remove”

button towards the right of the description. The FTD2XX Uninstaller program starts and displays a dialog asking you to disconnect the USB cable if it is still connected.

4. Unplug the USB cable connected to the Lambda 10-3, and then click the Continue

button. The uninstall process completes (one more dialog shows up indicating that registry entries and files are getting deleted). The uninstall process is now complete -click the Finish button to finish. Alternatively, click Cancel to cancel the whole uninstall process.

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 10-3 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 10-3 after having gone through the uninstall process, Windows will most likely be able to locate the necessary USB driver file on your

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

system during the installation process, without requiring you to supply the disk containing the driver.

If you wish to completely remove the USB driver and related files from the system, use either of the following two methods.

1. Manually delete the file FTD2XX.sys from the “system32” directory in your Windows

directory.

2. Navigate via My Computer or Windows Explorer to the “system32” directory in your

Windows directory, locate the file FTD2XXUN.EXE, and double click on it to launch the general-purpose FTDI uninstaller program. Running this uninstall program will remove all pertinent FTDI entries in the Windows registry, a far safer approach to removing the entries manually.

In Lambda 10-3’s programmed with firmware version 1.21 or later, the parallel port is enabled for use.

When configured to do so, the Lambda 10-3 microprocessor sets the PARALLEL port as the input source upon startup and anytime the ON LINE key is pressed. An appropriate command from the remote computer through the PARALLEL port will also set that port as the active input source and the display on the controller will reflect that change on its bottom line. The PARALLEL port will remain active until an appropriate command is sent from a remote computer through the SERIAL port or until the LOCAL key is pressed on the controller keypad. This chapter discusses these connections and the structure of the data that is required from your computer for controlling the filter wheel(s) and shutter(s) through the PARALLEL port. Many of the details about the command structure that apply to use of the SERIAL and USB ports, also apply to the PARALLEL port.

Input Command StructureInput Command Structure

Input Commands to the controller via the parallel port are structured in a one-byte (8-bit) signal. These eight bits are transmitted to the Lambda 10-3 controller via the eight input lines (Pin 2 through Pin 9) of the parallel port connector. The eight bits can be used to convey two types of input commands.

Filter Commands:

Filter Commands: These input commands select the desired filter position (0 – 9),

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

The microprocessor 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.

8.2.1

8.2.1 Filter Commands

Filter Commands

8.2.18.2.1

Filter CommandsFilter Commands

When the 8-bit command is identified by the controller as a Filter Command, the bit pattern is actually interpreted as three separate commands (or command parameters). The filter position is encoded in the four “least significant” bits, the speed is encoded in the “next three most significant” bits, and the wheel select is encoded in the “most significant” bit. These three functionally distinct filter command parameters are described in the following:

Binary codes with decimal values greater than 9 are ignored, unless the binary value (in conjunction with the Speed Group Bits) corresponds with the decimal equivalent of one of the Special Command Codes listed later in this chapter (see).

To send a filter command via the PARALLEL port the binary value must first be determined for the desired filter position, switching speed (4 bits and 3 bits, respectively), as well as the filter wheel (1 bit). Then these eight bits must be set, in the proper order, on the controller’s PARALLEL port, as shown below.

In Table 8-2, “Decimal Group Values” are equivalent to the values of the desired filter wheel (0 = Wheel A), switching speed (5) and filter position (7). Their binary equivalents are shown as the “Binary Group Values”. These eight bits are the raw data, then, that serve as a filter command to select the filter position, switching speed and filter wheel via the parallel port.

When the controller is in the ON LINE (Remote) mode, the eight input lines on the parallel port are examined at 50-microsecond intervals. If the value on the 8-bit input lines (pins 2 -

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

9) has changed from the previous query, and if the new filter group value (pins 2 - 5) are in the range of 0 to 9, the controller will respond as commanded with a change in the filter position of the appropriate filter wheel. In the above example (Table 8-2), Filter Wheel A will move to Filter Position 7, using Speed 5.

When the 8-bit command is identified by the controller as a “Special Command”, the bit pattern is interpreted as a single command encoded by all eight bits. The functions of the special commands are described below along with the decimal, hexadecimal, and binary values that encode them. All commands described in the chapter on Remote Control for the Lambda 10-3 are valid for the parallel port.

Using Fewer than Eight Input Lines

8.4.28.4.2

In some applications, not all of the eight input lines would have to be connected to the host computer. It is likely that the same speed will be used at all times with a given set of filters. Thus, the three lines that control speed could be directly wired so that the correct speed is always set. The direct wiring could even be made through a switch so that the speed could be changed if desired. If fewer than 9 of the ten filter positions will be used, it may be possible to direct wire some of the filter control lines, as well. With only one line, it is possible to select between two positions; with two lines, four positions are allowed, and three lines allows eight positions.

In the extreme case, then, where a protocol requiring the switching between only two filter positions is used, only a single logic level input line from the host computer to the controller (together with direct-wired connections to the other 7 lines) would be sufficient.

that the address used for each of the various I/O ports is correct for the user's system.

The parallel printer port is actually composed of three I/O ports at three consecutive addresses. The first address corresponds to an 8-bit output port, the second to a 4-bit input port, and the third to a 5-bit input/output port. The first two ports are used in our example. The address of the first (output) port, which is the base address, should be one of three possible values, depending on the individual system.

If the printer adapter is located on a display adapter, it will be called LPT 1 and will have a base address of 956 (3BC H). If there is no active printer adapter on a display adapter card, the primary printer adapter card will be called LPT1 and will have a base address of 888 (378 H). A second printer adapter card in the same system will be called LPT2 and will have a base address of 632 (278 H). Check the documentation of your system and the jumpers on the various adapter cards to be sure of the base address on the adapter you wish to use.

Where the decimal value of port would be 956, 888, or 632 depending on your system, and data would be a number indicating the desired speed and filter number.

The number to use for data can be generated from the desired speed and filter as follows:

data = wheel[0 for A; 128 for B] + filter position + (speed * 16)

Thus, to command a move to Wheel A, Filter Position 1, at Speed 1 (0 + 1 + 16 = 17), using a printer adapter having a base address of 888, you would use the following command:

The 4-bit input port only uses the 4 most significant bits at that address: bits 4, 5, 6, and 7. Bits 0, 1, 2, and 3 are not used by the printer adapter and will normally read as 1. Bit 7 in this input port is normally used by the printer to signal that it is “busy”. That bit is set by the data signal from the printer to Pin 11 of the DB-25 parallel port connector on the back of the computer. The Lambda 10-3 uses this same bit in the computer’s printer adapter to indicate that it is BUSY, although the polarity of this signal may differ from the corresponding printer BUSY signal.

With the Lambda 10-3 BUSY line connected to Pin 11 of the computer’s parallel printer port, the input port can be read to obtain the status of the Lambda 10-3. Using Microsoft QuickBasic, this would be done as follows:

Listing 8-2. Program to obtain the Lambda 10-3 status on the PC parallel port.

BUSY: OUT BASEPORT+2, 16 ‘Required on some computers ‘before data can be read FOR U = 0 TO 5 ‘Delay to allow Lambda 10-3 NEXT U ‘to set busy flag LOOK: STATUS = INP(INPORT) ‘Read in from printer port STATUS = STATUS AND 128 ‘Mask to read only bit 7 IF STATUS <> 128 THEN GOTO LOOK ‘Still Busy so loop

RETURN ‘Not Busy so return

The example given will loop until the BUSY signal is low. When developing a program, it is advisable to insert an escape device in this loop, such as:

IF INKEY$<>”” THEN RETURN

If you are stuck in a tight, endless loop without an escape device, you will have to reset the computer. This statement may be removed once the program is operating correctly.

An alternative command to use in Microsoft QuickBasic is WAIT. This statement has the form:

WAIT

port

, AND

data

, XOR

data

Where the port is the address of the input port, and data is an integer in the range 0 to 255. When the WAIT statement executes, program execution halts until the input port indicated

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

port

reads as the indicated by data expressions. The AND

data

expression is evaluated as

an AND operation. Thus, we may test to see if the BUSY line is set as follows:

WAIT 889, 128

The program will suspend operation until the value read for the most significant bit is 1. Since the printer adapter inverts this bit, this condition will be met only when the BUSY line is low. An XOR operation can be used as well, as noted in the Microsoft QuickBASIC Language Reference. The WAIT statement will XOR the read data before the AND operation if a value for XORdata is provided. Consider the statement:

WAIT 889, 128, 128

The XOR of the read value of the port with 128 will invert the most significant bit. The program execution would thus be suspended until the BUSY signal went high, indicating that the unit was busy. Using the 2 statements in series would insure that the controller had time to assert the BUSY line in response to a command before the program began to test to see if the BUSY line had come back down:

WAIT 889, 128, 128 WAIT 889, 128,

AN IMPORTANT CONSIDERATION WHEN USING THE WAIT STATEMENT:

AN IMPORTANT CONSIDERATION WHEN USING THE WAIT STATEMENT: The

AN IMPORTANT CONSIDERATION WHEN USING THE WAIT STATEMENT:AN IMPORTANT CONSIDERATION WHEN USING THE WAIT STATEMENT: WAIT statement seems to be ideal because it provides a fast and easy way of directly testing input port bits. However, if the input port does not have the correct value, and you are unable to force the port to the correct value, you will need to reboot the computer. This should not be a significant problem in routine operation of a system, but it can provide considerable frustration when developing and testing the control program. Test the WAIT function with simple programs before you use it. Make sure that you will not lose important data if you are forced to reboot.

8.68.6

Dedicated TTL LineDedicated TTL Line

Unlike the commands through the 8 bit port, the direct logic input lines will act even if the BUSY

BUSY line is active. However, these lines only provide the conditional opening: the shutter

BUSY BUSY will open while the wheel is stopped. It follows that the only advantage of the direct control lines is that, in a two-shutter system, the shutter associated with a wheel that was not moving could be opened or closed while the other wheel is moving. When the controller is in the manual mode, the dedicated TTL lines are ignored. If a valid 8-bit shutter command has been received by the controller, the dedicated TTL lines are ignored until the controller is reset.

The dedicated input lines are at pins 14 and 16 of the 25-pin parallel connector. Shutter A is opened by setting pin 14 high and closed by setting pin 14 low. Shutter B is opened by setting pin 16 high and closed by setting pin 16 low. Remember that this is a conditional opening: the shutter will be open only if the corresponding wheel is not moving.

If the 25-pin connector is brought to a PC parallel adapter, pins 14 and 16 correspond to the AUTOFEED and INITIALIZE control lines for a printer. These lines are controlled by setting bits in the command port of the printer adapter, which is at an address that is equal to the base port address + 2.

Pin 14 corresponds to the bit that encodes the value 2 and pin 16 corresponds to the bit that encodes the value 4. Sending a value of 2 to this port will set pin 14 low, which closes the

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

shutter. Pin 14 can be set high to open the shutter by sending a value such as 0. The logic for pin 16 is the reverse of pin 14. To open shutter B, send a value of 4 to the port. To close shutter B, send 0 to the port. Since both shutters are controlled by the same port, you must combine the values for the two shutters by addition if you have two shutters installed.

In addition to the control of the shutter via the keypad, serial port, USB port and the parallel port, the direct TTL logic input can also control the shutter. However, input must be selected and configured for the mode desired. TTL level inputs could come from a wide variety of devices, such as cameras, imagining boards, or a parallel port.

The parallel port has been used extensively for control of shutters through logic level signals. The outputs available at pins 14 and 16 of the 25-pin parallel port are usually employed. Pin 14 corresponds to the bit that encodes the value 2 and pin 16 corresponds to the bit that encodes the value 4. Sending a value of 2 to this port will set Pin 14 low, which closes the shutter. Pin 14 can be set high to open the shutter by sending a value such as zero. The logic for Pin 16 is the reverse of Pin 14. To open Shutter B, send a value of 4 to the port. To close Shutter B, send 0 to the port. Since both shutters are controlled by the same port, you must combine the values for the two shutters by addition if you have two shutters installed.

The Lambda 10-3 has two types of TTL inputs for shutter control. The first type is provided for by the two BNC connectors on the back of the Lambda 10-3 controller case, both labeled TTL IN. The Lambda 10-3 is shipped with this type factory configured. The second type consists of using the Lambda 10-3’s PARALLEL PORT Pin 14 for Shutter A TTL IN and Pin 16 for Shutter B TTL IN. Both types are mutually exclusive. That is, if the BNC TTL IN connectors on the rear of the cabinet are enabled, then pins 14 and 16 of the parallel port are disabled, and vice versa. The TTL IN type is selected by changing a jumper on the main printed circuit board inside the Lambda 10-3 cabinet.

Note that if the use of the parallel port pins 14 & 16 as TTL IN are disabled (i.e., the TTL IN BNC connectors on the rear of the cabinet are enabled), the rest of the pins in the parallel port are not affected. Remote control of the Lambda 10-3 via parallel port using commands sent over the 8 data lines may continue unchanged regardless of which type of TTL IN shutter control is being used (Parallel port pins 14 & 16 or BNC connectors on the rear of the cabinet).

The TTL IN lines are switched between the external BNC connectors on the rear of cabinet and pins 14 and 16 of parallel port by changing two jumpers inside the controller cabinet. The following figures show the location of these jumpers, their settings, and how the two settings are designated. When a jumper is in the “Par.” Position, the TTL IN for that shutter (A or B) is active on the parallel port (Pin 14 and/or 16). When a jumper is in the “TTL”

LAMBDA 10-3 OPERATION MANUAL – REV. 3.03 (20110829)

position, the TTL IN for the selected shutter (A or B) is active on the corresponding BNC connector mounted externally on the rear of the controller cabinet.

The jumpers are accessed by removing the top of the controller cabinet. Carefully remove the eight screws from the top of the cabinet, and two screws from the upper part of each side.

The TTL IN control of Shutter A and Shutter B each can be independently enabled or disabled. If enabled, the way in which TTL IN works can also be set to one of the following:

1. Open shutter when TTL IN is set to high.

2. Open shutter when TTL IN is set to low.

3. Toggle shutter’s state on the rising edge of a high signal on TTL IN.

All of aforementioned settings must be set in the Lambda 10-3’s LOCAL or OFF LINE mode. The controller is placed in local mode by either pressing the LOCAL key on the controller’s front panel keypad or by sending a “Go Off Line” command (239 decimal or EF hexadecimal) from a host computer connected to whichever remote control interface (USB, serial, or parallel) is currently in the “On Line” state. When the Lambda 10-3 is in the local (off line) mode, an “L” is shown in the upper right-hand corner of the controller’s display.
