6. Introduction
This GUI User Manual describes the control and operation of SPI’s R4 CW-M High Power Fibre
Lasers using a PC based Graphical User Interface (GUI). This GUI User Manual does not provide
exhaustive information on the functioning of the laser. The user should read the Product
Manual in conjunction with this manual. The purpose of this User Manual is to familiarise the
user with the operation of the GUI.
The laser can be operated in the following configurations:-
Ethernet
RS-232
PC
Laser
Signal Generator
Laser in internal (From GUI) control mode with setup and operation under RS-232 control
from the GUI. An external signal generator with TTL output is required to provide the laser
modulation waveform.
PLC controller
Ethernet
RS-232
PC
Laser
Signal Generator
Laser in external (From PLC Port) control mode with external analogue signals for power
setpoint and readback. Full control and monitoring of the laser status is possible over its I/O

7. Installation
As the GUI is a standalone .EXE with no supporting files required an installer package is not
required. Copy the provided .EXE file into an appropriate folder on your PC to install the GUI.
8. Start up problems
8.1. No COM port available
The user may see the following message before the application starts:
“COM port selected is not currently available”
If the initialisation file is not found (as will be the case the first time the software is run), or an
RS-232 port previously used has been removed from the system, the default port may not
exist on the PC running the application.
If the user has been working with a PC using a USB-Serial converter, this may be displayed if
the serial cable is removed and the application started.
9. Connecting to the R4 Fibre laser
Refer to the Product Manual SM-S00051for information on how to connect to the laser.
10.
Main Window
When the application successfully runs the main window of the GUI will appear as shown
below.
The GUI supports multiple languages. A flag representing each supported language is present
in the top right of the main window. Clicking the appropriate flag will set the desired
language.

The main window contains the most common controls needed to operate the laser, as well as
parameters read back from the laser such as the currently set power level. The sections of this
window are described below.
10.1. Laser Configuration
This section allows the user to adjust three parameters:

Power Level Source - Clicking “Change” will toggle between “From GUI” or “From PLC
Port”. This sets whether the laser’s power level is set by the “Power” section of the
main window described below (From GUI) or by a voltage on the PLC port (From PLC
Port).

Feedback Mode – Allows the user to select Open Loop or Closed Loop power control.
RS (Reduced Specification) lasers do not allow Closed Loop operation, and so this
option is disabled.

Control Mode – Allows the user to select between two control modes – one suitable for
“CW / Slow Modulation” and the other for “Fast Modulation”. For the differences
between these modes, and guidance on when they should be used, refer to the laser
manual.
There is also a fourth parameter “Control Source” displayed here. This cannot be set in the
GUI, but is set by toggling the “Use Port” pin on the PLC port (see the laser product manual).
When the Control Source is set to “PLC Port”, many functions of the GUI will be disabled as
signals on the PLC port will control these options.
The Laser Configuration cannot be altered while the key switch is on.
10.2. Laser State
This section displays the current state of the laser system. Possible states are detailed below:

KEY OFF. The laser is disarmed (safe) and emission is not possible.

SAFETY DELAY. This mode is entered for a short period after the key is turned.

IDLE. The laser is armed but not currently emitting.

EMITTING. The laser is currently emitting light.

CYCLE KEY. A key cycle is required before operation can continue. This message is
displayed if the laser is powered up with the key in the “on” position, if the user
attempts to arm the laser with the interlock open, or after certain alarms are cleared.

ALARM. An error condition is present. See the “Alarms and Warnings” section in this
document.

10.3. Power Setpoint and Readback
This section is used to set the required power. Note that if either “Power Level Source” or
“Control Source” is set to “From PLC Port”, this section will be disabled.
The desired power value can either be entered in watts, up to the maximum value shown, or
in percent. Enter the desired value and press Enter or click “Set”. Both displays will update
when either one is altered. The “Readback” values on the right will display the power level that
the laser is currently set to.
When the power level is being set from the PLC port, the “Readback” values will display the
power level being set by the external voltage.
10.4. Power Presets
This section allows four power presets to be set and recalled. Power presets can only be set or
recalled when the laser is in “From GUI” control mode.
10.5. Power Monitor
This section displays the actual laser output power taken from the internal photodiode.
The caption changes depending on whether the laser is set to “CW/Slow Modulation” or “Fast
Modulation” mode:

In “CW/Slow Modulation” mode, the caption is “Output Amplitude” because the laser is
monitoring each pulse individually and only measuring the power when the laser is
actually emitting.

This means that, if the laser is set to 300 watts, the Output Amplitude will show as
300 watts regardless of what the duty cycle is.

In “Fast Modulation” mode, the caption is “Average Output Power” because the laser is
disregarding the modulation signal and reporting the average power over time.

This means that, if the laser is set to 300 watts, the power displayed will be 300 watts
if continuous modulation is being used. If the modulation signal is at 50% duty cycle,
the power displayed will be 150 watts.
10.6. Pilot Laser Control
This allows the red pilot laser to be enabled and disabled. The circular indicator shows the
current state of the laser. This control is disabled when the laser is being controlled from the
PLC Port.
It is possible for the supervisor to set which modes the pilot laser can be used in. If the Enable
button is clicked when the laser is in a mode which does not allow pilot laser emission, an
error message “The Pilot Laser is not operable in this control state!” will appear.
10.7. Alarms and Warnings
This section displays information on any alarms and warnings which are currently present.
Warnings are for information only, and will disappear when the error condition is removed.
Alarms are latching, requiring clearance by a supervisor, and prevent operation of the laser
while the alarm state is present.
Alarms and warnings appear as shown:

If there are multiple alarms or warnings the display will cycle through them.
The “Clear Alarms” button can be used to clear any alarms that are present. This requires both
that the alarm condition is no longer present (for example, if a temperature alarm occurs, the
laser must cool down before the alarm can be cleared) and that the user is logged in with an
appropriate access level.
A Fibre Fail Alarm can only be cleared by running a special routine (see Supervisor section).
The “Help” button can be used to display more information about alarms and warnings that
have occurred, along with information on how to clear them or prevent them happening
again:

Communications
The Communications dialog box is brought up by clicking the “Comms” button on the main
window.
There are two possible ways to establish communications between the laser and the PC: RS232 and Ethernet. The two radio buttons in the top left allow the user to select which type of
interface they desire. The “Help” button will display troubleshooting information for the
selected interface.
11.1. RS-232 Connection
To establish serial communications the COM port and baud rate must be set. Should the user
wish to change the COM port, click the “Close” button and select a com port from the “Com
Port” drop down menu. Only the COM ports available will be displayed. The baud rate may
also be changed in the same way. Click the “Open” button and the COM port should open. The
communication status for normal operation is shown by the “Command…” indicator cycling
through the numbered commands. RS-232 settings are stored when the application is shut
down.

11.2. Ethernet Setup
The user can change the Ethernet settings by entering the Supervisor window and selecting
the “Set Setting” command. This allows the user to change:
1. Static IP Address
2. Static IP Mask
3. Static IP Gateway
4. Ethernet Mode (Static or DHCP)
5. Flash the Ethernet interface with new firmware.
Note that commands 1 through 4 cannot be executed when connected via Ethernet.
Command 5 can only be executed when connected via Ethernet.
11.3. Ethernet Connection
If the user knows the IP address of the laser then this may be typed directly into the four edit
boxes provided.
11.4. Ethernet – Finding lasers on the network
If the IP address is not known then the GUI provides the capability of finding the laser on the
network. Pressing the “Find” button displays a new dialog box as shown:
The central display panel shows a list of lasers found on the network. For the user the most
important item is the serial number. If this laser displayed is double clicked then the dialog
box is closed and the IP address is filled into the boxes in the Communications window.

The GUI is multiple network card compliant. If two network cards are fitted the user should
select the card which is connected (via the network) to the laser. In the example above the
“Broadcom” network card is selected.
11.5. Ethernet – Changing IP settings over the network
The user should normally set the laser IP status by using the RS-232 interface, however it is
possible to set the laser parameters over the Ethernet connection. This can be done by
pressing the “Rescue” button. A new dialogue box like this appears:
The user must know the serial number of the laser as well as the addresses and mode
required. Pressing the Set button should change the settings of the laser selected. Note that
the mechanism used is UDP - this is not as reliable as TCP so depending upon network
reliability the user may need another attempt.
This feature is also useful if the laser is mistakenly set to a static IP address which is not
accessible with the current network configuration.
11.6. Ethernet – Debugging
Pressing the “Debug” button provides additional information about the network connection.
This feature should only be used to provide additional information to SPI if requested.
11.7. Command Analysis
The communications dialog box may also be used to assist the user in debugging their own
communications software. The automatic transmission cycle can be interrupted by pressing
the pause button as shown here:

The values of the bytes transmitted and received are shown in grids. Pressing the next button
will transmit the next command in the cycle. If a specific command is required which is not
part of the automatic cycle the user should navigate to that command, click the button and
then return to the Communications dialog box. Pressing the “Send Single” button will send the
desired command.
11.8. Touchscreen Mode
The last item to note on Communications dialog box is the “Touchscreen Mode” check box
which may be checked when using a touch screen (see Touch Screen section below).
12.
Access Level dialog box
This dialog box is opened by clicking the “Access Level” button on the main window:

There are two levels of access allowed to Users. The default is the “Operator” level which
permits all basic operational commands and setup windows to be accessed. The “Supervisor”
level requires a passcode to allow access to extended setup and reset options. Higher level
access options remain greyed out until the correct passcode is entered. The Supervisor
passcode can be found on the test report for each laser.
The supervisor access period is limited to 10 minutes. To prevent unauthorized changes to
the setup and to ensure that supervisor access is not left open to operators the “Operator
Level” button should be pressed to revert the access back to operator level. The “Operator
Level” button in the supervisor window has the same function.
To enter the Supervisor passcode click on the edit box to the right of the “Set” button. Enter
the passcode. Note that the passcode is displayed as “XXXX” to ensure security.

Two of the temperature readings may not be present depending on the configuration of the
attached laser. The BDO temperature only appears if the laser is fitted with a BDO that has a
temperature sensor. The Inlet Water temperature only appears if the laser is configured for
humidity sensing.
14.3. Digital I/O Status
This section indicates the state of the input and output pins of the 25-way I/O port on the R4
Fibre Laser. The pin numbering is given in the fibre laser Product Manual. The “Port Status” at
the top of this section indicates whether the PLC port is currently being actively used to
control the laser. This is set by Pin 3, “Use Interface” – if this pin is high, the laser will be set
to “From PLC Port” control mode.
14.4. Software Version Information
This section gives the version numbers of the firmware on the fibre laser’s NXP and AD
processors. Holding the mouse pointer over the NXP firmware number will give additional
detail about the version.
14.5. On Times
This section gives, to the nearest second, the total time the unit has been powered on and the
total time it has been emitting.
14.6. Relative Humidity
This section only appears if humidity sensing functionality is fitted and enabled in the
connected laser. Relative Humidity (RH) and Dew Point - temperature at which condensation
will start to form - are given for the Electronics Module and the Optical Module. If the inlet
water temperature gets too close to the dew point, a warning will appear. If the inlet water
temperature decreases further, the solenoid will close and an alarm will trigger.
15.
Performance Options
This window allows setting of the pump simmer settings and control of the XPR mode. These
options must be enabled by the Supervisor before they are visible. The circles to the right of

15.1. XPR
XPR stands for Extended Performance Range. This mode is designed specifically for operation
at low average powers, but with a reduced optical response time. Refer to the Product Manual
for further details. The Mode is controlled by the Enable and Disable buttons.
15.2. PSE
PSE is used to ensure the first pulse has similar characteristics to all subsequent pulses. Refer
to the Product Manual for further details. Enter the required simmer level in the box, then
click “Set”. The Get button gets the current simmer level. To disable PSE, set the level to zero.
CAUTION: When PSE mode is engaged it is possible for the Fibre Laser to
emit at output powers of up to 4W when NO modulation signal is present.
The output level will depend upon the PSE setting.

Clicking the Supervisor button on the main window gives access to some setup and reset
operations which are not available with the operator access level. Once the window has been
opened the supervisor has one minute to complete the required tasks.
The following functions are available:
16.1. Clear Output Alarm
CAUTION: If the reset routine is unsuccessful after the first attempt,
contact the supplier immediately for advice.
CAUTION: During the conditional reset procedure the fibre laser will
be set to emit optical power. Ensure the beam delivery optic is
securely mounted, pointing towards a suitable beam dump and the
end cap has been removed before starting the reset sequence.

CAUTION: Before starting the reset sequence, ensure all laser safety
precautions are adhered to and laser safety eyewear is worn at all
times as defined in Section 1.2. of the product manual.
If the laser internal output power monitoring system detects the absence of an optical output
in response to an input set-point and modulation signal, an Output Power Alarm will be
activated and the system safety shut-down will activate. If this alarm is activated a self
checking routine can be executed to conditionally reset the system.
To reset the Output Power Alarm:

Apply a constant CW TTL high signal to either the modulation input on the PLC port or
the BNC connector and close the key switch.

Click the “Clear” button to initiate the reset procedure and wait for confirmation of
successful execution in the read back window. Once confirmed, recycle the front panel
or remote key-switch to reset the laser system.
The laser is now reset and ready for continued operation.
16.2. Calibrate
CAUTION: During the self-calibration procedure the fibre laser will
be set to full rated output power. Ensure the beam delivery optic is
securely mounted, pointing towards a suitable beam dump and the
end cap has been removed before starting calibration.
The high reliability design of the fibre laser includes the provision of optical pump power
overhead in order to compensate for the random failure of the pump diodes over the system
design life as well as any temperature dependence in the optical system. In the event of a
pump diode failure the drive current to output power calibration will change. With closed loop
power control this may prevent the laser from reaching the power set-point. To prevent this,
a simple periodic recalibration procedure ensures that the available diode current is
incrementally increased to maintain the rated laser output power over life.

Ensure the laser is in the emit mode.

Click the “Go” button to initiate the calibration procedure and wait for confirmation of
successful execution in the read back window.
Note : RS (Reduced Specification) lasers do not have an automated calibration routine. To
replace this feature, a manual calibration feature is available. In the event of a pump diode

failure the drive current to output power calibration will change. The manual calibration
routine is accessed from the Maintenance command on the Supervisor tab, and is described in
the below section.
16.3. Maintenance
Several different maintenance commands can be selected from the drop-down list. The user
should refer to the command manual FS-S00031 for comprehensive information. The options
available are:
16.3.1. Drain Unit
This option will keep the water flow solenoid valve open to allow the laser to be drained of
water prior to shipment. Note that the laser must be powered when draining takes place as
the valve needs power to be kept in the open state.
16.3.2. Set RS-232 Baud Rate
The RS-232 baud rate may be changed using this option. Reliable RS-232 operation will
depend upon the type of RS-232 cable, its length and how electrically noisy the operating
environment. If the cable supplied by SPI is used, the recommended speed is 38400. If this
option is left at “Auto” there is the possibility that a communication error will occur depending
upon the sequence of turning on the laser and GUI.
16.3.3. Set & Get CANOpen ID
This option is reserved for future use.
16.3.4. Set Calibration
HS lasers can carry out an automatic calibration routine to determine the calibration value.
However, RS lasers require the user to set the value manually. This option facilitates this
manual setting.
The procedure for using this command is as follows:CAUTION: During the manual calibration procedure the fibre laser
will be set to full rated output power. Ensure the beam delivery optic
is securely mounted, pointing towards a suitable beam dump and the
end cap has been removed before starting calibration.
1. Using appropriate safety arrangements, aim the laser at a power meter capable of
absorbing the rated power of the laser.
2. Using the power setting window of the GUI set the laser to 100% power
3. Adjust the calibration value bring the laser output back to its rated power. Increasing
the calibration value increases the laser power. Lasers start life set to 205. Only

increase the calibration value to allow rated power to be achieved - do not exceed
rated power at 100% power setting.
4. If a setting of 255 is reached and the laser is not at rated power then the laser has
reached End of Life.
5. When the calibration value is correct set the power to zero using the power setting
window and disable the laser using the key switch. Cycle the mains power.
The new calibration value is now set and the calibration is complete.
16.3.5. Get Calibration
The current calibration value may be read using this command.
16.4. Settings
The settings which may be changed by the supervisor are:
16.4.1. Safety Delay
IMPORTANT: If the default value of this setting is changed the
Customer accepts the responsibility for meeting the laser safety
compliance requirements to the appropriate standards for the
integrated laser system.
The “Safety delay” is the length of time between the laser being enabled by the closure of the
safety relay, and laser emission being permitted. During this period the “Laser Enabled” LED
indicators on the panel display flash. The default delay time is 4 seconds. This can be
adjusted if required. Enter the new required value in milliseconds.
16.4.2. Static IP address
This is used to set up the Ethernet interface. The address is a number such as 192.168.1.53.
This address must be within the range of the network to which it is connected. If in doubt
contact your network administrator.
16.4.3. Static IP Mask
This is used to set up the Ethernet interface. The network mask is usually set to
255.255.255.0.
16.4.4. Ethernet Mode
There are two options, either “Static” or “DHCP”. Your network administrator will be able to
assist you in selecting the correct setting for your network.

16.4.5. RAL time out
The diode used in the Red Alignment Laser (RAL) has a finite life, so by default after 10
minutes it will turn off. The time may be changed to suit the user. The time is in minutes, and
may be a minimum of 1 and a maximum of 250.
16.4.6. Static IP Gateway
This is used to set up the Ethernet interface. The Gateway value should be provided by your
network administrator.
16.4.7. Ethernet MAC Address
The MAC address is a unique number which all network components must have to operate
successfully within the network environment. This number can only be read and not set.
16.4.8. Current IP Address
The IP address is used by the Ethernet interface. It can only be read and not set. If the
Ethernet mode is set to “Static” then this address will be the same as the “Static IP Address”. If
“DHCP” is selected then the network will allocate this address.
16.4.9. Flash Ethernet I/Face
This can only be set. The Ethernet interface has its own processor, and its firmware may be
updated using this option. The SPI service department will supply the file to use and full
instructions as to how to carry this out.
16.4.10. Ethernet Firmware Version
This value can only be read.
16.4.11. Pilot Laser set up
The Pilot Laser behaviour may be changed using this option. When selected, a configuration
matrix will appear. The columns of the matrix are the states of the laser. The Pilot Laser may
only be turned on if the user places a tick in the relevant state on the “Allow On” row. The
default setting does not allow the pilot laser to be on in Idle, Emitting or Delay states. To
replicate this behaviour the user need only tick one box:
In any other state such as Key Open, the user may send the “RAL On” command via the
computer interface or assert the RAL On pin on the 25 way IO connector if this is being used.
As soon as the key switch is closed to arm the laser the pilot laser will be extinguished.
To provide greater flexibility the user may also configure the pilot laser behaviour in other
states:


“Allow On” permits the pilot laser to be on in this state if the user requires it.

“Auto On” will automatically turn the pilot laser on when this state is entered. “Allow
On” must also be ticked in order for this functionality to work.

“Auto Off” will automatically extinguish the pilot laser when this state is entered. (This
will also happen if “Allow On” is not ticked – “Auto Off” will automatically turn the pilot
laser off, but allow it to be re-enabled.)
16.4.12. Solenoid always on
Water-cooled lasers contain a solenoid valve to close and open the water flow through the
coolant circuit. If enabled, this feature will open the solenoid all the time (except when a
humidity alarm is present). If disabled, the solenoid will open and close in response to laser
mode and temperature.
16.4.13. OPF Alarm
This feature is not currently in use.
16.5. Set Feature
This function will enable or disable a specific feature such as XPR. To see what features have
been enabled select “None” from the drop down list. A list of enabled features will appear
followed by “OK”.
The passcode is required both to enable and disable features, which are:
16.5.1. XPR - eXtended Performance Range.
This reduces the total available power of the laser but the first pulse after a long delay is
better formed.
16.5.2. PSE – Pulse Shape Equalisation
This improves the first pulse response of the laser without reducing the power output.
16.5.3. CAN
This feature is not currently supported.
16.5.4. IPM
This feature is not currently supported.

Controlling Multiple Lasers
One instance of the application cannot control multiple lasers. However, if multiple copies of
the program are copied into separate folders, each one can be run individually and configured
to operate a separate laser. Each instance of the program will create its own INI file with its
own configuration settings.
