1. INTEGRA
1.1. INTRODUCTION
The INTEGRA is a series of all-in-one detectors that combine a detector and a meter in one
convenient product. The small but powerful meter of the INTEGRA series presents a direct USB
or RS-232 connection so you can plug it into your PC. Simply use the PC-Gentec-EO software
supplied with your product and be ready to make power or energy measurements within
seconds! Each detector of the INTEGRA series offers the same incredible performance as the
usual detector and meter combination, from pW to kW and from fJ to J. And the good news is
that all our most popular products are available with the INTEGRA option.
1.2. SPECIFICATIONS
The following specifications are based on a one-year calibration cycle, an operating temperature
of 18 ºC to 28 ºC (64 ºF to 82 ºF) and a relative humidity not exceeding 80%. INTEGRA must be
stored in an environment between 10 ºC to 45 ºC (50 ºF to 113 ºF) and a relative humidity not
exceeding 90%. Photodiodes are sensitive to temperature, especially at longer wavelengths. It is
best to keep the temperature in the range of 25 ºC (77 ºF) close to the calibration temperature.

INTEGRA user manual Revision 3.7 6
Example for the external trigger timing requirements:
If the head detector has a risetime of Tresp = 20 µs, the time frame will be from
(20% * 20 µs = 4 µs) before the laser pulse to (20 µs –1 µs = 19 µs) after the laser pulse.
Then, the external trigger signal must happen between 4 µs before to 19 µs after the laser
pulse.
The graph below visualizes the synchronization of the external trigger signal compared to the
laser pulse signal.

1.2.2. Range adjustment
The INTEGRA monitor can add or remove the last available power or energy range depending
on the wavelength (spectral sensitivity), the repetition rate or the presence of an attenuator. This
is done so that the INTEGRA does not trigger on noise or that the electrical offset affects the
measurements.

INTEGRA user manual Revision 3.7 7
2. QUICK START PROCEDURE
1. Install the PC-Gentec-EO software on your PC.
2. Install the power or energy detector head on its optical stand.
3. Connect the INTEGRA device to the PC with the appropriate USB cable.
4. Start the PC-Gentec-EO software.
5. Choose the appropriate display for your measurement:
a. Real time with bar graph
b. Scope
c. Needle
d. Averaging
e. Histogram
f. Statistics
6. Press the Connect button on the top left corner of the main window and change the
measurement and display options in the appropriate tabs.
a. Power heads will default to power measurement. Energy heads will default to
energy measurement. The display will default to a dual display in real time and
scope in auto range mode.
b. Remove the head’s protective cover and start the laser.
Put the detector head into the laser beam path. Leave it there for a few minutes
until the detector has reached an equilibrium temperature. The entire laser beam
must be within the sensor aperture. Do not exceed the maximum specified
densities, energies or powers. For the most accurate measurement, spread the
beam across 60% to 80% of the sensor area.
Warning: Power detectors can be used with both CW and pulsed lasers.
Energy detectors can only be used with pulsed lasers.
7. Adjust the zero:
The power read by PC-Gentec-EO when no laser beam is incident on the detector may
not be exactly zero. For power measures, this is because the detector is not thermally
stabilized OR there was a heat source in the field of view of the detector when you
connected the PC-Gentec-EO. As for photo detectors, zeroing will remove the
detector’s offset.
Thermal and pyroelectric detectors: Block all laser radiation on the detector. To reset
the zero, wait until the reading has stabilized and click Set Zero in the main menu.
Photo detectors: You must block all forms of radiation (cover the detector). Click on
Set Zero in the main menu. In some software versions, a message will appear
requesting you to put the black cover over your photo detector. Press the OK button
after you have done so. The software passes through all the scales to determine the
zero for each scale.
See notes.

INTEGRA user manual Revision 3.7 8
Notes:
a. Refer to specific power detector documentation for complete installation and operating
instructions.
b. Power detectors are thermal sensors and are thus sensitive to temperature variations.
c. For high-precision measurements, it is recommended to:
i. Allow the power detector to thermally stabilize before zeroing the software.
ii. Touch only the stand when handling the power detector. Do not touch the detector
itself. This is especially true for highly sensitive detectors.
iii. Do not adjust the zero for energy detectors, such as the QE series.
iv. Avoid forced airflow or drafts around the detector.
3. USER INTERFACE
Please refer to the PC-Gentec-EO manual for more information concerning the user interface.

4. USB AND RS-232 SERIAL COMMUNICATION
4.1. DESCRIPTION
The INTEGRA has two communication modes: the binary mode for fast data acquisition and the
ASCII mode. Both modes will require text input commands which must follow the rules stated
in Section 4.3. The output can be in binary mode or in ASCII mode. Section 0 describes all the
commands in ASCII output mode, but keep in mind, it is also valid for binary mode, as described
in Section 4.4.
The USB class used by INTEGRA is a CDC or Communication Device Class. This means it shows
up in the host PC as a COM port, but it is not a COM port, rather a true full speed USB port. You
can communicate with this port as if it were an RS232 port, but very fast when it comes to speed.
Follow the Windows command prompts to install the USB drivers. The USB drivers are fully
tested and digitally signed by Microsoft.
Open the appropriate port in your software with standard COM port tools. None of the port
settings matter since they are not used, so leave them at whatever default they are in. It is a real
USB connection.
Use the standard COM port writes and reads to control the INTEGRA.
4.2. SETTING UP COMMUNICATION TO THE INTEGRA
4.2.1. Verify the COM port
To verify the USB installation and find the COM port number, click:
Start → Settings → Control Panel → System → Device Manager
Scroll down to Ports (COM & LPT) and double click on that line. One of the options should be:
INTEGRA USB-Meter (COM#)
Note the COM port number, you will need it for the next step.
4.2.2. Connect the INTEGRA
You may use any serial communication software that you are familiar with. Our instructions are
for HyperTerminal because it is widely available on PCs with Windows.
Select:
Start → Programs → Accessories → Communications → HyperTerminal
To save the communication settings, enter a name for the connection. In the “Connect using”
drop-down menu, select the COM port that the USB driver was installed on (Section 4.2.1).
Select OK.
Input the following settings into the communication parameter window that appears next.

Click OK to begin entering serial commands in the HyperTerminal window.
4.2.3. To echo commands
The commands you type will not appear in the HyperTerminal window unless you set up the
HyperTerminal to do so. Only the response from the INTEGRA will be displayed. If you prefer to
see the commands you are typing on the HyperTerminal window, click on the File menu and
execute the following sequence:
File → Properties → Settings → ASCII setup → “Echo typed characters locally” → OK
4.2.4. Test the connection
In the HyperTerminal window, type *VER. If the response is the version of your INTEGRA, you are
successfully connected and ready for serial command actions.
4.2.5. To add a character delay
In some cases, the INTEGRA has connection problems that can be solved by adding a delay
between characters. To adjust this delay, click on the File menu and execute the following
sequence:
File → Properties → Settings → ASCII setup → “Character delay”: add a few milliseconds
of delay → OK
4.2.6. HyperTerminal shortcut settings
When you end the session, HyperTerminal asks if you want to save your settings. To avoid
inputting the communication parameters again in the future, save by clicking Yes. The next
time you execute the string of commands, the name of your session will appear after
HyperTerminal. Clicking on the session name will open the connection using the saved settings.
To avoid re-entering the string of commands, put a shortcut to this file on your desktop: Search
for the file name, select the file. Right click and select Shortcut in the drop-down menu.
4.3. SERIAL COMMAND FORMAT
4.3.1. Serial protocol rules
Commands are sent as text strings. The response will either be data or an empty string.
4.3.2. Text mode rules
All text commands must begin with a trigger character (*). You do not need to end with a line
feed or a carriage return. Parameters must NOT be separated by spaces. Characters do not have
to be capitals, mixed upper and lower cases are fine. Replies to all text mode commands are also
in text mode and end with a carriage return and a line feed.

INTEGRA user manual Revision 3.7 11
In case of an error, the reply string is one of the following:
“Command error. Command not recognized.”
or
“Command error. Command must start with '*'”
Because all text mode replies end with a carriage return <CR> or a line feed <LF> (or both), a text
reply contains tabulations when many elements need to be separated in the string. This is useful
when exporting data to a spreadsheet.
4.4. BINARY MODE OUTPUT FORMAT
4.4.1. Description
The INTEGRA’s resolution is 12 bits for the joulemeter mode. To be compatible with other
Gentec-EO monitors, a 14-bit value is sent, but the two LSBs of the low byte are not significant.
Only joulemeters support the binary mode. Thermopiles in energy mode, thermal heads in
standard mode and photo detectors are coded in ASCII.
By default the joulemeters are in ASCII mode. To turn on the binary mode, send the
command *SS11. Please refer to the Detailed Description of the Serial Commands for INTEGRA
(Complete) section for more information.
All commands are valid in binary mode and are sent as text strings as well. Only the
commands *CAU, *CVU, *CEU and *CTU will return binary results. All other commands will reply
in ASCII.
Examples to decode binary commands
Decoding *CAU or *CVU
If you send *cau, INTEGRA will send continuous data with 2 bytes per pulse.
If you send *cvu, INTEGRA will send the current measurement with 2 bytes per pulse.
Bit 7 of each byte is the order bit, and the rest is the binary data. If the order bit is 0, the byte is the high
byte. If the order bit is 1, the byte is the low byte. You must then mask, shift the MSB, add and divide the
data by the scale. See the example below.
The 2 bytes are decoded as follows:
Byte 2
0XXX XXXX.0 = High byte, and X is the upper binary data. If it is over the range, this byte is 0xFE.
Byte 1
1XXX XXYY. 1 = Low byte, X is the lower binary data and Y is not significant data. Y will always
be 0. If it is over the range, this byte is 0x7F.
Example 1: Using *CAU or *CVU
INTEGRA is measuring 151 mJ in a 300 mJ scale. The data sent by INTEGRA will be: 0x40B4.
Decode this as follows:
1. Look at bit 7 of each byte to determine the high and low bytes.
2. Keep bits 0 to 6 of each byte (and with 0x7F).
3. Shift the high byte left by 7 bits (multiply by 128).
4. Add the high and low bytes.
5. Divide the result by the full-scale value, 16,382.
6. Multiply the result by the set scale, 300 mJ.

INTEGRA user manual Revision 3.7 12
Examples to decode binary commands
The two data bytes are 0x40 and 0xB6. In binary they are: 0100 0000 and 1011 0100.
The byte order bit is 0 for the high byte and 1 for the low byte. The high byte is therefore 0x40, and the
low byte is 0xB6.
The data is the lower 7 bits of each byte or high byte of 0x40 and low byte of 0x34.
Shifting the high byte 7 by its results in 0x40 x 128 = 0x2000.
Adding this value to the low byte results in 0x2034, or 8,244 decimal: 8,244 / 16,382 * 300 mJ = 151 mJ.
If the value of these bytes is 0xFE7F, an out-of-scale condition exists.
Decoding *CEU or *CTU
If you send *ceu, INTEGRA will send continuous data with 9 bytes per pulse.
If you send *ctu, INTEGRA will send the current measurement with 9 bytes per pulse.
The 9 bytes are decoded as follows:
Byte 8
Always 0X02 or STX. Let the host know this is the start of data.
Byte 7
The scale index or with 0x80. This is done so it can never be the STX or ETX byte. Therefore, if
the scale was set to 29, then this byte would be hex (29) = 0x1D. Or this with 0x80, and the value
sent is 0x9D.
Byte 6
The upper 7 data bits of the energy, or'd with 0x80. If the pulse is over the range, this byte
is 0xFE.
Byte 5
The lower 7 data bits of the energy, or'd with 0x80. If the pulse is over the range, this byte is 0x7F.
Byte 4
The upper 7 bits of the pulse period timer, or'd with 0x80 (28 bits total).
Byte 3
The next 7 bits of the pulse period timer, or'd with 0x80 (28 bits total).
Byte 2
The next 7 bits of the pulse period timer, or'd with 0x80 (28 bits total).
Byte 1
The lower 7 bits of the pulse period timer, or'd with 0x80 (28 bits total).
Byte 0
Always 0X03 or ETX. Let the host know this is the end of the data.
Example 2: Using *CEU and *CTU
INTEGRA is measuring 151 mJ in a 300 mJ scale. The pulse frequency is 1531 Hz. The data sent by INTEGRA
will be: 0x0297A0B68080FABC03.
Decode this as follows:
1. The valid data is between the 0x20 (Start of Text) and 0x03 (End of Text) codes.
2. Valid data is 0x97A0B68080FABC.
3. The first byte is the scale, or'd with 0x80.
4. The second and third bytes are the data, each or'd with 0x80.
5. The remaining 4 bytes are the pulse period counts, each or'd with 0x80.
Valid data is 0x97A0B68080FABC.
The scale byte is 0x97. Mask off bit 7 resulting in 0x17 or 23 decimal. The scale is 23 or 300 mJ.
The energy data bytes are 0xA0B6. If the value of these bytes is 0xFE7F, an out-of-scale condition exists.
If no out-of-scale condition exists, mask off bit 7 of each byte: 1010 0000 1011 0110 ≥ 0010 0000 0011 0110,
resulting in 0x2036 or 8,246 decimal: 8,246 / 16,382 * 300 mJ = 151 mJ.
The pulse period bytes are 0x8080FABC. Mask off bit 7 of each byte resulting in 0x003D3C or
15,676 decimal. The period timer is based on a 24E6 Hz clock, so the period is found as:
If you send *ceu, it will be 15,676 counts / 24E6 counts per second = 653.17us.
If you send *ctu, the pulse frequency will be 1 / 653.17us = 1531 Hz.
