SHORT ARC XENON LAMPS AND SYSTEMS

Proper use and safe operating practices are the responsibility of equipment manufacturers who incorporate the lamp into equipment and users of such lamps and equipment. The supplier of this lamp provides information on its products and associated hazards, but it assumes no responsibility for aftersale operating and safety practices. All lamps are under pressure and must be handled with care. Take appropriate action through baffles, light shields, interlock switches or other safeguards to protect personnel from harm due to operation and/or failure of the lamp.

SAFE OPERATING INSTRUCTIONS

Do not operate this lamp except in accordance with proper operating instructions and within recommended operating specifications. Direct questions regarding lamp operation or safety to your lamp supplier.

OPERATING HAZARDS

Read the following instructions and take all necessary precautions

I. EXPLOSION - The lamps are filled with xenon gas at very high pressure. Lamps must be handled with the same care and caution given any vessel containing these levels of pressure. A hazard exists if the window or ceramic fractures and may cause explosive mechanical failure. Face shields or proper safety glasses are recommended during all handling operations.

II. HIGH VOLTAGE - Ignition voltage of some lamp models is very high and can be deadly. If portions of the circuit are exposed, caution must be used in setup and operation of the system. The input power must be disconnected from the power source before attempting any service to the lamp.

III. INFRARED AND ULTRAVIOLET RADIATION - Do not look directly at operating lamps orb reflected light. Infrared and ultra violet radiation generated by the lamp can cause skin burns and permanent eye damage.

CERMAX® Lamps

LAMP DISPOSAL

CERMAX lamps do not have reclaimable parts. Before disposal, it is recommended to relieve a lamp’s gas pressure by squeezing the tip-off with pliers until the gas escapes. If gas pressure is not relieved, care should be taken to discard the lamp in a landfill and not an incinerator.

SAFETY HAZARDS

The operation of lamps involves one or more of the following hazards. In the absence of safe operating practices and precautions, any one of these hazards could result in injury.

IV. OZONE - Some UV type lamps generate ozone, a toxic gas, by virtue of the ultraviolet radiation. A lamp which gives off ozone must be operated in a well ventilated area..

V. HOT SURFACES - Portions of the lamp can reach temperatures of several hundred degrees centigrade and cause serious burns if touched even after the lamp is turned off.

Some Basic InformationSome Basic Information

The optical path subsystem in the Lambda DG-4 is arranged so that 2 mirrors, each mounted on a fast closed-loop servoed galvanometer, can route the collimated output of the lamp through one of 4 optical paths (e.g., filter position 1 in the diagram below). Slide-in filter holders allow 25 mm (or 1 inch) diameter filters to be introduced in each of the four optical paths. An additional slide-in filter holder, intended for neutral density filters, is located in a portion of the optical system common to all light paths. After passing through the filter positions, the lamp output is focused on a 2-meter long UV (ultraviolet) transmitting light guide, which acts as a conduit for the output to the microscope. At the output of the light guide, an optical adapter collects the output and delivers it to the microscope.

Figure 3-1. Lambda DG-4 optical pathway.

The following instructions are meant to help you set up the Lambda DG-4 and verify that the Lambda DG-4’s subsystems are operational using the manual mode of filter selection. More detailed discussions of controller function, filter installation, the light source, assignment of filter numbers and remote communications can be found in other sections of this manual.

3.2 Getting Started

Getting Started

3.23.2

Getting StartedGetting Started

1. Connect the power cord to the socket on the back panel of the Lambda DG-4. Make certain that the voltage selector next to the power cord socket has been properly preset to the appropriate voltage (110 or 220). Do not turn on the power, yet.

2. Insert either end of the light guide into the port on the top panel of the Lambda DG-4 cabinet (see below) and tighten the thumbscrew to hold it in place. The top of the light guide end sleeve should be flush with the top surface of the port fitting (see below). This should result in maximal or near-maximal light output from the light guide. Minor adjustments up from this position may improve output, and can be easily made once the system is fully installed.

Figure 3-2. Light guide installation.

3. The other end of the light guide should be installed in the microscope using the appropriate adapters (see the installation sheet provided with the specific adapter that has been ordered) or directed away from anyone’s eyes and toward a non-reflective surface. DO NOT LOOK DIRECTLY INTO THE LIGHT GUIDE!

4. A hose should be connected to the 4” fitting on the back of the Lambda DG-4 cabinet to ventilate the ozone from the xenon lamp to the environment or to an ozone removal device.

5. Identify the small access door used to install the neutral density FILTER HOLDER. This access door is located near the top edge of the left side panel on the Lambda DG-4 cabinet (see below). Loosen the black knob on the access door and slide it up to install the empty Neutral Density FILTER HOLDER (the neutral density FILTER HOLDER is the one whose bottom surface is flat rather than grooved). Make certain that the end nearest the filter cup goes in first. If you would like to install a neutral density filter at this time please refer to the “Loading Filters” section of this manual.

LAMBDA DG-4 & DG-5 OPERATION MANUAL – REV. 2.14 (20081107)

Figure 3-3. Lambda DG-4 left side.

6. Identify the large access door used to install the interference FILTER HOLDERS. This access door is located in the middle of the left side panel on the Lambda DG-4 cabinet (see above). Loosen the black knob on the access door and slide it up to install the remaining four FILTER HOLDERS (the ones that have a groove on their bottom surface). Install the two FILTER HOLDERS that contain blanking disks in FILTER POSITIONS 3 and 4. If you would like to install interference filters at this time, please refer to the “Loading Filters” section of this manual.

7. Make certain that the free end of the light guide is installed into the microscope or is directed toward a non-reflective surface and away from anyone’s eyes. DO NOT LOOK DIRECTLY INTO THE LIGHT GUIDE.

8. Turn on the power to the lamp subsystem using the switch labeled LAMP on the back panel of the Lambda DG-4 cabinet. Due to the current draw during lamp ignition, it is important to power up the LAMP first (before the MAIN switch is turned on) to avoid damage to the circuitry of the other Lambda DG-4 subsystems. This same precaution applies to the order in which you power up other electronic and computer equipment that might be powered from or grounded to the same circuit as the one used for the Lambda DG-4. GO DIRECTLY TO THE NEXT STEP! DO NOT OPERATE THE LAMP FOR MORE THAN A FEW SECONDS WITHOUT TURNING ON THE MAIN POWER SWITCH!

9. Within a few seconds of turning on the LAMP switch turn on the power to the optical path and controller subsystems using the switch labeled MAIN on the back panel of the

LAMBDA DG-4 & DG-5 OPERATION MANUAL – REV. 2.14 (20081107)

Lambda DG-4 cabinet. The Lambda DG-4 will boot up and briefly display the initialization screen followed by the MAIN MENU (shown on top of next page).

INPUT = MANUAL MOVE ON COMMAND INPUT = MANUAL MOVE ON COMMAND

10. The Lambda DG-4 is under LOCAL (keypad) control upon start-up, as indicated by the words “INPUT - MANUAL” on the MAIN MENU (see above). MOVE ON COMMAND is the active operational mode at start-up, which means that filters are selected by pressing the numeric keys corresponding to the desired FILTER NUMBER (see EDIT A FILTER NUMBER definition of this value). The default FILTER NUMBER upon start-up is “0”. This setting will disrupt the optical pathway within the Lambda DG-4 and prevent any light output at the light guide port. The “0” FILTER NUMBER serves, then, as a “shutter” whenever it is selected.

11. Press the “1” key followed by ENTER. This FILTER NUMBER is pre-programmed at the factory to cause the light to be directed through the FILTER HOLDER that is loaded into position 1 and then onto the light guide with maximal light output (i.e., minimal attenuation).

12. Now experiment by selecting FILTER NUMBERS 0 through 4. Anytime you select a single digit FILTER NUMBER you must complete the entry by pressing the ENTER key or you must precede the single digit with a “0”. FILTER NUMBERS 0,1,2,3 and 4 are pre-programmed to correspond with the closed “shutter” and the four FILTER POSITIONS (with minimal attenuation), respectively.

Now that you have completed the “Make it Glow” section of the manual, you should be familiar with the basic components and operation of the Lambda DG-4. To get set up for an experimental application you will need to:



Install the LIGHT GUIDE into the OPTICAL HOLDER (if not already in place).

Install the OPTICAL HOLDER into the microscope using the appropriate adapter (if not already in place).



Install the desired filters into the FILTER HOLDERS (if not already in place).

The light output of the Lambda 10 DG4 is focused onto one end of a liquid light guide. The output of the liquid light guide can then easily be coupled to your microscope or optical system using correct mechanical adapter for your microscope. Please note that the light guide has a minimum-bending radius of 40 mm (about 1.6 inches).

The liquid light guide should have black sleeves over the ferrules on both ends. These ferrules, or “end sleeves”, are designed to slide into the mounting flange on the lambda DG-4 cabinet and the output adapter. Insert the end of the light guide into the light guide port until the top of the black end sleeve is even with the top of the light guide port. Tighten the locking screw on light guide port to secure the end of the light guide in position. This should result in maximal or near-maximal light output from the light guide. Minor adjustments up from this position may improve output; the adjustments can be easily made once the system is fully installed.

The free end of the light guide slides into one end of the optical holder tube (shown below). The other end of the optical holder tube has a UV grade fused silica lens system (in the “short cup”). By sliding the light guide toward or away from these lenses, the light guide output can be collimated or brought to a focus. The optical holder, in turn, slides into the dovetail adapter, which has a “dovetail” collar on one end. This collar is used to fasten the entire assembly to the microscope system using an adapter (not shown) that is specific to the microscope make and model. Refer to the documentation included with each microscope adapter for further installation instructions.

The two sides of a filter are usually not identical due to differences in their surface coatings. Some form of labeling will be present to differentiate the two sides. It is important to refer to the filter manufacturer’s documentation to interpret the labeling and determine the proper orientation relative to the light source. Remember, the light path inside the Lambda DG-4 travels from BOTTOM TO TOP. Therefore, the filters should be oriented with their “Lamp Side” down.

At the end of each filter holder is a filter cup assembly (shown below). There are at least two items installed into the filter cup at the factory: a threaded retaining ring and a spacer ring (to carry the force of the retaining ring to the unthreaded portion at the bottom of the cup). In two of the filter cups, there will also be a blanking disc. Installation of filters into the filter holders requires care and patience to avoid damaging the threads of the filter cups and retaining rings as well as the filters.

Figure 4-3. Filter holder assembly.

The threaded retaining ring has two notches cut into it, 180 degrees apart. Place the notched end of the brass spanner wrench into the notches on the retaining ring and carefully unscrew it. If a retaining ring has been previously over-tightened, it is possible that the filter cup will begin to unscrew from the slider. If this occurs, STOP. Turn the spanner wrench around and, using the other end, insert it into the slots at the top of the cup. Then 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.

Once the retaining ring is removed, the spacer (and blank, if present) should fall out. You should become familiar with the assembly of this retaining system. In particular, you should develop a feel for tightening the retaining ring without pushing on the 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.

Figure 4-4. Filter holder assembly with blanking disc.

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

Next, install the spacer ring into the filter cup. Unless the filter thickness precludes the use of the spacer ring, always install the spacer to provide maximum separation between the filter surface and end of the brass spanner wrench that is used to turn the retaining ring.

Finally, install the threaded retaining ring.

In most cases, any given filter could be installed at any of the four FILTER POSITIONS. However, some minor considerations may improve performance of the system. Adjacent FILTER POSITIONS will require slightly less switching time. Therefore, if an experiment will require rapid switching between two filters they should be located next to one another. If separated by one or more filters, there will be brief transitions through the intervening filter(s) unless the TURBO-BLANKING feature is enabled (see “Modes of Operation”). While this feature eliminates the transmission of light at unwanted wavelengths, it does further increase the time required for switching.

Filter switch timing can be controlled using one of four different operational modes.

• MOVE ON COMMAND (default mode)

• MOVE ON STROBE PULSE

• MOVE ON SYNC PULSE

• MOVE ON SYNC PULSE, INHIBITED BY THE STROBE LINE

The default mode (“MOVE ON COMMAND”) allows you to directly command filter changes (e.g., using the numeric keys on the keypad when the Lambda DG-4 is under LOCAL (“Manual”) control). Filter changes can also be controlled using an external trigger (“MOVE ON STROBE PULSE”), video synchronization pulse (“MOVE ON SYNC PULSE”) or a combination of these two external sources (“MOVE ON SYNC PULSE, INHIBITED BY THE STROBE LINE”). By default, the Lambda DG-4 will be in the MOVE ON COMMAND mode when it starts up, and at any time after a “triggered” mode has been inactivated. The active operational mode (of these four) will be indicated on the right side of the bottom line in the MAIN MENU.

In addition to the above operational modes that control the timing of the filter changes, there are four others available which alter the Lambda DG-4’s function:

• EDIT A FILTER DEFINITION

• SETUP THE RING BUFFER

• TURBO-BLANKING

• DISPLAY THE FIRST 4 FILTER VALUES

All of the eight operational modes listed above may be accessed from any one of the three sources of control input, LOCAL (keypad), SERIAL PORT or PARALLEL PORT. Although the details of how an operational mode is selected may vary somewhat from one source of input to another, its function remains the same. In this section, the operational modes will be described in terms of LOCAL control. Separate sections discussing interfacing the Lambda DG-4 with remote devices (computers) will cover access to these same modes of operation using SERIAL and. PARALLEL inputs.

If the Move on Sync Pulse Mode is active, the controller will advance to the next filter in a previously programmed FILTER NUMBER sequence (Ring Buffer) when an internal video synchronization (sync) circuit detects the vertical sync pulse of a composite video signal applied to the SYNC input on the rear of the Lambda DG-4. In this way, filter changes can be coordinated to occur with the capture of video “frames”. The FILTER NUMBER sequence can be programmed at your convenience and then executed later with precise timing (see SET UP THE RING BUFFER). The FILTER NUMBERS can also be sent individually via the serial or parallel port before the trigger event.

This mode combines the functions of the MOVE ON SYNC PULSE and the MOVE ON STROBE PULSE modes (see above) to allow the capture of more than one video frame before advancing to the next filter in the previously programmed series of FILTER NUMBERS (Ring Buffer). In this mode the Lambda DG-4 controller will ignore the SYNC input until it detects a state change in the STROBE LINE, from HIGH to LOW. Then it will advance to the next filter in synchrony with the next vertical sync pulse that occurs. The computer interfaced with the Lambda DG-4 must be set up to monitor the video signal and hold the STROBE line HIGH if the number of frames to be captured with each FILTER NUMBER is to be constant. This option might also be used to solve some timing problems that can result when using inherently fast software or computers. Selection of this mode is made by pressing the MODE key followed by the 6666 key to get to the MOVE ON SYNC, INHIBITED BY THE STROBE LINE menu.

5.6.7.1 General Information The optical pathway for light from the xenon lamp in the Lambda DG-4 is determined by the

angle at which the mirrors on the Input and Output galvanometers are positioned. The Input Galvanometer directs the collimated light beam through one of the four FILTER POSITIONS (shown below) and, thus, through whatever interference filter is installed there. The angle of a Galvanometer is not expressed in degrees, here, but in an arbitrary unit whose value ranges from 0 to 4095. The Input Galvanometer Value that defines the optimal light path for each of the FILTER POSITIONS in your Lambda DG-4 has been determined at the factory, and is provided on a separate Optical Alignment Data Sheet (see the example shown below).

Figure 5-4. Optical pathway based on filter position.

The position of the Output Galvanometer must be coordinated with that of the Input Galvanometer to complete the optical pathway to the Light Guide Port (shown above). The Output Galvanometer angle is also expressed in an arbitrary unit whose value ranges from 0 to 4095. The discrete Output Galvanometer Value that defines the optimal light path for each of the FILTER POSITIONS has been determined at the factory, and can be found on the Optical Alignment Data Sheet. The following table shows some typical Galvanometer Values for each FILTER POSITION.

5.6.7.2 Filter Numbers The Lambda DG-4 uses paired Input and Output Galvanometer Values to define a given

optical pathway. Any pair of Galvanometer Values can be assigned a FILTER NUMBER from 1-15. It is important to remember that a FILTER NUMBER is a “logical filter” and does not necessarily correspond to the number on the cabinet that labels the FILTER POSITION through which that optical pathway passes. The Input and Output Galvanometer Values that define the optical pathway that passes through FILTER POSITION number 4 in the sample values shown above would be 1000 and 4000, respectively. Those Galvanometer Values could be assigned any FILTER NUMBER from 1 through 15.

Figure 5-5. DG-4 output attenuation.

5.6.7.3 Attenuation If the Output Galvanometer value is either slightly increased or decreased from the value

that produces the peak output, the light coupled into the light guide will decrease as schematically depicted in the figure on the following page. The nominal relationship between galvanometer value and output is shown in the plot below. The exact relationship may vary from unit to unit and filter position to filter position. The actual attenuation produced must be determined by the user. The degree of attenuation produced by increasing the galvanometer value is similar to that produced by an equivalent decrease. Remember, though, that you are limited to an overall range of 0 to 4095. If the output galvanometer value for maximum output is already within 1000 units of a limit (0 or 4095) it is logical to attenuate by changing the value in the direction that moves away from that limit. This method is very useful for attenuating output by less than 1 log unit. It is recommended that you use neutral density filters when attenuation of 1 log unit or more is desired.

LAMBDA DG-4 & DG-5 OPERATION MANUAL – REV. 2.14 (20081107)

Figure 5-6. Log of attenuation vs. change in output galvanometer value.

5.6.7.4 Programming a Filter Number (“Logical Filter”)\ The Galvanometer Values that define the maximal light output through FILTER

POSITIONS 1,2,3 and 4 have been assigned FILTER NUMBERS 1,2,3 and 4, respectively, at the factory. It is recommended that these assignments be retained but there is no overwrite protection. If you do edit these values, the original values can be found on the Optical Alignment Data Sheet that came with your Lambda DG-4. Galvanometer Values, which maximally misalign the Input and Output Galvanometers, have been assigned FILTER NUMBER 0. When selected, this FILTER NUMBER will prevent light output and serve as a “logical shutter”.

The EDIT A FILTER DEFINITION mode is the operational mode from which you assign paired Galvanometer Values a FILTER NUMBER. It is selected by pressing the MODE key followed by the 7777 key to get to the EDIT A FILTER DEFINITION menu. Alternatively, you can “page” through the mode selection menus by pressing MODE.

5.6.8.1 General Information The Lambda DG-4 controller will accept a sequence of up to 32 FILTER NUMBER values

into its non-volatile memory as part of the “RING BUFFER”. This sequence of FILTER NUMBERS can then be “played back” during an experiment. It is possible to program a total of 64 FILTER NUMBER values into the RING BUFFER but the additional 32 values are stored in a volatile memory and will be lost if the Lambda DG-4 is turned off or RESET.

The values in the RING BUFFER can be stored and viewed while in any operational mode but it can only be RUN from one of the “triggered” operational modes since the filter changes are dependent on a STROBE PULSE or SYNC PULSE.

NOTES:

As the optical pathway is transitioning between two FILTER POSITIONS that are not adjacent to one another, the Input Galvanometer must briefly direct the light through any filter(s) intermediate to the desired FILTER POSITION. Under normal operation, the Output Galvanometer moves in phase with the Input Galvanometer and, therefore, maintains the optical pathway to the Light Guide Port as the filter change occurs. This results in a brief output of light at an undesired wavelength prior to arriving at the selected FILTER POSITION. This problem can usually be avoided by placing filters in adjacent FILTER POSITIONS when it is known in advance that you will only want to switch between those two wavelengths. This may not be a practical solution for several situations. The TURBO-BLANKING operational mode eliminates the transmission of undesired wavelengths during filter changes by forcing the Input and Output Galvanometers to move out of phase with one another. In this way, the optical pathway to the Light Guide Port is broken until the Input Galvanometer has arrived at the selected FILTER POSITION and the Output Galvanometer catches up with it. This feature does increase the time required for switching, though. This operational mode is selected by pressing the MODE

The Lambda DG-4 has both serial and parallel interfaces but these two interfaces should not be connected simultaneously. The parallel port provides you with the fastest remote interface possible. The serial port connection provides you with a similar range of commands but at a significantly slower speed. A serial interface therefore will not fully exploit the Lambda DG-4’s rapid filter changing capability. Remote control of the Lambda DG-4 is similar to that of the Sutter Lambda 10 filter wheel but functional differences in these units require the elimination of some commands and the addition of others. All of the commands are byte (8-bit) values. This corresponds to a single character from the serial port or the value encoded by the eight logic level input lines of the parallel port.

The parallel interface connector on the back of the cabinet is a DB-25 connector. The connections are arranged so that a standard DB-25 cable can be used to connect the controller to a PC parallel port. This cable should not be used simultaneously with a serial port cable connected to the Lambda DG-4.

The pin assignments for this connector are, as viewed from the back of the unit:

The 8 input lines of the parallel input (data input lines 2-9) are read by the controller as an 8 bit value with input line 9 corresponding to the most significant bit. When the control unit is in the ON-LINE (remote) mode, the 8 input lines are examined at 50 microsecond intervals. If the value of the filter or command indicated by the input lines has changed from the previous time the lines were read, the control unit will set the BUSY line and then respond as commanded. See the BUSY LINE section for further details about this data line.

NUMBER that corresponds to the command’s decimal value (0 to 15). Another way of stating this is that when the 4 most significant bits of the 8 bit binary value all equal 0 (data input lines 6-9 are all LOW) the 4 least significant bits (data input lines 2-5) will be treated as a four place binary number whose decimal value corresponds to the desired FILTER NUMBER (0-15).

The next 16 binary values (00010000-00011111) are also read as “filter change” commands. These commands will not be executed, however, until the next “trigger” (STROBE or SYNC PULSE, depending on the mode that is active) has been detected. Each of these commands selects the FILTER NUMBER that corresponds to the command’s decimal value less 16. If, for example, you want to select FILTER NUMBER 6 on the next STROBE PULSE, you would send the binary equivalent of the decimal number 22 (00010110). Another way of describing these commands is as follows. When the binary value of the three mostsignificant bits is 0 (data input lines 9, 8, and 7 are all LOW), and the next least-significant bit’s binary value is 1 (data input line 6 is HIGH), then the four least-significant bits (data input lines 5, 4, 3, and 2) are treated as a 4-bit binary number that corresponds with the desired FILTER NUMBER (0 - 15).

Twenty-two of the remaining 224 binary values are used to send commands to the Lambda DG-4. These commands are listed in the table on the following page with their corresponding Input Values and descriptions of their functions.

The Lambda DG-4 parallel interface has only one output line, BUSY. The first response of the unit to a new command is to set the BUSY output line HIGH. The BUSY line will stay HIGH until the control unit is ready to accept new data..

The status of the 8 input lines is not checked while the BUSY line is HIGH! There is a short period (as much as 50 microseconds) between when the control unit detects a new value and the BUSY line is set HIGH. Thus, checking the status of the BUSY line within about 100 microseconds of changing the input lines may give a misleading result.

The BUSY line used in the Lambda DG-4 was originally implemented in an earlier version of the software that was written for the Lambda-10, a much slower filter-switching device. Because of the DG-4’s superior filter switching speed, it is not always necessary to attend the state of the BUSY line. In many experimental applications, the Lambda DG-4 could be controlled entirely by using only the eight data input lines. The extreme example of this approach would occur when all that is needed in your application is to toggle between two FILTER NUMBERS. In this case, you could select between FILTER NUMBERS 1 and 3 by holding the least significant bit value (data input line 2) HIGH while toggling the next least significant bit value (data input line 3) LOW and HIGH. The remaining data input lines (4-9) could simply be grounded to hold those bit values LOW.

Using Input Lines with the BUSY Line

Using Input Lines with the BUSY Line:

Using Input Lines with the BUSY LineUsing Input Lines with the BUSY Line

The conditions that cause the BUSY line to be asserted are noted in the previous paragraph. Reading the status of the BUSY line allows the host computer to determine if the unit is ready to receive a command. A command sent while the BUSY line is HIGH will not be executed until the BUSY line goes LOW. It is possible, then, when using high performance software and hardware that the first of two commands sent in succession could be “lost”. Monitoring the state of the BUSY line (Pin 8) can avoid such losses and make time-consuming “time-outs” in the software unnecessary.

Controlling the Lambda DGControlling the Lambda DG

4 from a Computer’s Parallel (Printer) Port

4 from a Computer’s Parallel (Printer) Port4 from a Computer’s Parallel (Printer) Port

The standard PC parallel port provided for printer control may be used to control the Lambda DG-4. This, however, does not mean that instructions can be sent to the Lambda DG-4 in the same manner that they are sent to a printer. A printer is designed to print at its maximum rate, and if the computer generates output at a higher rate, the printer will store the output in a buffer until the mechanism is ready. If the buffer becomes full, the printer will indicate to the computer that it is not ready to accept more data. It follows that there is not a tight time relationship between the output of a command from the computer and the execution of that command by the printer.

The time relationship between output of data from the computer and response by the Lambda DG-4, in contrast, must be very tight. Thus, it is understandable that the mode of use of the parallel port will be somewhat different for a printer and the Lambda DG-4.

The details of the input and output signals were described previously. Now we will discuss the way in which these signals may be used to control the Lambda DG-4 from a PC compatible computer’s parallel port. This information is provided as a limited example and is only intended to show the elements useful in controlling the Lambda DG-4. The user’s individual requirements, hardware, and software will dictate the actual program steps to be used. The approach in this example does involve direct control over the state of input and output ports. The example programs have been run successfully on computers from several manufacturers without encountering any difficulties. However, given the wide range of hardware and software in use, it is impossible to anticipate all possible problems. Sutter Instrument Company thus cannot be responsible for any damages that might result from use of the example programs. The user should be particularly careful 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.

The connections to the parallel port are made through a DB 25 connector on your computer. The pin assignments for the computer parallel port connector are, as viewed from the plug side:

Commands may be sent through the printer adapter by using an OUT command from basic, or an equivalent command from another language. In Microsoft QuickBasic the form of the command is:

LAMBDA DG-4 & DG-5 OPERATION MANUAL – REV. 2.14 (20081107)

OUT port, data

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 command.

The number to use for data either will be one of the FILTER NUMBERS or will correspond to one of the commands in the table presented earlier in this section. Thus, to command a move to FILTER NUMBER 4 using a printer adapter having a base address of 888, you would use the following command:

The BUSY line is the only output from the Lambda DG-4. In the BUSY line section (above), there is a discussion of some of the factors to consider in deciding whether to read the BUSY signal at all. If you have determined that your application requires this output to be read from your computer, this can be done through the 4-bit input port on the printer adapter. The address of this port will be the base address of the printer adapter plus one.

The 4-bit input port uses only the four 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 DG-4 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 DG-4 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 DG-4. Using Microsoft QuickBasic, this would be done as follows:

Listing 6-1. A routine for obtaining the status of the DG-4.

LAMBDA DG-4 & DG-5 OPERATION MANUAL – REV. 2.14 (20081107)

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

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 by port reads as the indicated by data expressions. The AND an AND operation. Thus, we may test to see if the BUSY line is set as follows:

port

, AND

data

, XOR

data

expression is evaluated as

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 XOR

data

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 control unit 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,

THERE IS AN IMPORTANT CONSIDERATION WHEN USING THE WAIT STATEMENT! The 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.

Shutter ControlShutter Control

The “shutter” is treated as a special FILTER POSITION whose Galvanometer values are assigned to FILTER NUMBER 0. These values set the Galvanometers so that the light path is interrupted, and, therefore act as a shutter when the FILTER NUMBER 0 is selected. The shutter is effectively opened by selecting the desired FILTER NUMBER. If, however, in writing a routine to control the DG-4 you wish to return to the last FILTER NUMBER used but do not want to keep track of that value in your program, shuttering can be done using the CLOSE SHUTTER and OPEN SHUTTER commands. OPEN SHUTTER will

LAMBDA DG-4 & DG-5 OPERATION MANUAL – REV. 2.14 (20081107)

automatically return the Galvanometers to whatever FILTER NUMBER was last selected before being closed by the CLOSE SHUTTER command. The mechanical effect is the same as selecting FILTER NUMBER 0 to close the shutter followed by the desired FILTER NUMBER to open the shutter.

RS-232 serial control of the Lambda DG-4 is provided through a 9-pin connector on the rear of the controller cabinet. Only the ground and the two data lines are connected: the hardware control lines are not connected. This cable should not be used simultaneously with a parallel port cable connected to the DG-4.

Figure 6-3. Serial control connections (viewed from rear of cabinet).

LAMBDA DG-4 & DG-5 OPERATION MANUAL – REV. 2.14 (20081107)

Communication for the serial port requires the following settings:

• Data Rate: 9600 bps (bits per second) or “baud”

• Data Bits: 8

• Parity: None

• Stop Bits: 1

• Flow Control: None

No hardware control lines are connected. The communication mode must be set so that either these lines are ignored, or connections to these lines are made that satisfy the communications mode desired. In Microsoft Quick Basic, 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 Basic to ignore the DCD, CTS and DSR control lines.

In order to send commands to the Lambda DG-4 via the serial port, you must first place the Lambda DG-4 in the serial mode. If the Lambda DG-4 is in either the parallel or manual mode it can be placed in the serial mode by simply sending the decimal value 238 (EE hexadecimal) via the serial port. Do not send this data value by both the serial and parallel port, since this will cause the controller to rapidly switch between modes. If you send 238 via the serial port, it will be retained as the serial input until another serial command is received. Thus, if you send it via the serial port and do not send another character, neither the manual nor parallel modes can be selected for proper operation.

The mode is indicated on the front panel display. The display will indicate either PARALLEL, MANUAL OR SERIAL. The unit automatically selects the parallel mode at power on. When the value of 238 is received, the display will switch to indicate SERIAL. If any communication errors occur, they will be indicated by the * symbol following the word SERIAL. If the 238 command is not received correctly because of communication errors, the * symbol may replace letters in the word PARALLEL.

Each 8-bit command listed under the parallel port instructions can also be sent through the serial port. Since the serial data format used is 8 bit, each character sent is a command. If you have used a BASIC language open statement to establish serial communications, the subsequent 8 bit command values may be sent using a 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.

For most commands sent over the serial interface, a simple form of protocol is provided that can be used to determine the success or failure of commands and the speed at which commands are transmitted.

In order to read the responses using BASIC, you can use a statement such as:

LAMBDA DG-4 & DG-5 OPERATION MANUAL – REV. 2.14 (20081107)

IF LOC(1) > 0 THEN SerialInput$ = INPUT$(1, #1)

LOC(1) > 0 indicates that bytes are waiting in the received data buffer. INPUT$(1, #1) reads one byte from the buffer, which is stored as SerialInput$.

6.2.3

6.2.3 Serial Port Command Echo

Serial Port Command Echo

6.2.36.2.3

Serial Port Command EchoSerial Port Command Echo

In the serial mode, the Lambda DG-4 controller responds to each command by echoing the command back to the host computer. This indicates that the command was received and will be executed promptly. If the sent command is the same as the last command received, it will not be echoed and the controller will take no action. The following subroutine could be used to hold the computer in a loop until the command is properly echoed.

Listing 6-2. Command echo check routine.

COMMANDCHECK: IF LOC(1) > 0 THEN SerialInput$ = INPUT$(1, #1) IF DATANUM = ASC(SerialInput$) THEN RETURN GOTO COMMANDCHECK

NOTE: The only serial command not echoed back by the Lambda DG-4 is the “Go On Line” (238 decimal, EE hexadecimal) command.

In the case of filter movement commands (0 through 32), the Lambda DG-4 will send back to the host computer a byte with the value of 13 decimal (0D hexadecimal), which is an ASCII CR (carriage return). Nearly the same subroutine can be used to hold the computer in a loop until the carriage return (13) is received.

The Lambda DG-4 controller signals that it has completed commands received through its serial port by sending a carriage return back. The following is an example of a QuickBasic routine that could be used to monitor the status of the DG-4 (the example assumes that #1 has already been opened as the serial port to which the DG-4 is connected.

In the event that the lamp fails to power up when the power switch is turned on, please check to see if the line power fuse has blown. The fuse is located in a pry-out holder on the power entry module on the back of the lamp (see figure on Page 17). To remove the fuse holder first unplug the power cord from the power entry module. This will reveal a slot just under the edge of the fuse holder. Use a screwdriver to pry the holder straight out of the power entry module.

Figure A-1. Fuse replacement.

The fuse that is readily visible in the fuse holder when you take it out is the one that is “active” when the holder is installed. A spare fuse is also stored within the fuse holder. It is concealed in a compartment as shown in the figure. To remove the spare fuse, press down on the end of the compartment and push it out of the other end. The old fuse can serve as a convenient tool for pushing the spare fuse compartment out. Replace the active fuse with the spare and re-install the fuse holder and power cord. If the lamp fails to power up with the new fuse installed, call Sutter Instrument technical support personnel for assistance.

The value of the fuse required is a function of both the line voltage and wattage of the bulb in the Lambda DG-4. The following table gives the correct fuse values. The fuse supplied with the unit is the correct value for the unit as configured if the destination country was known at the time the lamp was ordered. All fuses are “time delay” or “time lag” type, with a glass-tube construction, and with a physical size of 5mm x 20mm. Specific fuse ratings depend on the power of the xenon lamp used in the Lambda DG-4/5, as indicated in the following tables.

are no ASCII character definitions for the codes in this range. However, many computers and operating systems do support characters within this range, although there is no single standard across all platforms. Furthermore, many operating systems, such as Microsoft Windows and Apple Mac OS X, have several “code pages” (character sets), many of which are country/language specific, from which the user can select. Therefore, this part of the table is left blank – if you wish, you may write in the characters defined in the character set you use on a regular basis.
