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 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 to 28ºC
(64 to 82ºF) and a relative humidity not exceeding 80%. INTEGRA must be stored in an environment between
10oC to 45oC (50 to 113oF) and a relative humidity not exceeding 90%. Photodiodes are sensitive to
temperature, especially at longer wavelength. It is the best to keep the temperature in the range of 25 oC (77oF)
close to the calibration temperature.

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 (Fig 2-1) 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 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 form of radiation (cover the detector). Click 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 1.1 4
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 irtself. 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. The manual can
be downloaded on our website at https://gentec-eo.com/downloads/specsheets-manuals.
4. USB 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 rules stated in section 4.3. The output can be in
binary mode or in ASCII mode. Section 4.6 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 Communications 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 talk to it like as if it
were an RS232 port, but very fast when it comes to speed. Follow the Windows 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’s 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 that line. One of the options should be
USB-to-Serial Port (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 communications software that you are familiar with. Our instructions are for
HyperTerminal because it is widely available on PCs with Windows.

INTEGRA User Manual Revision 1.1 5
Select:
Start → Programs → Accessories → Communications → HyperTerminal
To save communication settings, enter a name for the connection. n the drop down menu for “Connect using”
select the COM port that the USB driver was installed on (Section 4.2.1). Select OK.
Input the following settings into the communications parameter window that appears next.
INTEGRA COM Port Settings
Bits per second
Any settings will work
Data bits
Any settings will work
Parity
Any settings will work
Stop bits
Any settings will work
Flow control
Any settings will work
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 setup 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 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 action.
4.2.5. HyperTerminal Settings Shortcut
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 trig character (*). You do not need to end with a line-feed and/or a carriage-
return. Parameters must NOT be separated by spaces. Characters do not have to be capitals, mixed upper and
lower cases is ok. 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 1.1 6
In case of an error, the reply string is in the following format:
Error X: reason [enter]
Where Xis the error code, and reason is an explanation. See Error Codes at the end of this
section.
Because all Text Mode replies end with a carriage return <CR> or 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 resolution of both is 12-bit in Joulemeter mode. A 14-bit value is sent for compatibility with other meters, but
the two LSB’s are not significant.
Only the Joulemeters support the binary mode. Thermopiles in energy mode, thermal heads in standard mode
and photo detectors are coded in ASCII.
The value in binary mode is coded in two bytes.
4.4.2. Codification
When retrieving a measurement with either *cau or *cvu command the output is decoded as follow:
Byte 1
OXXX XXXX
Byte 2
OXXX XXXX
Where O is the byte Order bit, and X is the binary data. If O is 0, the byte is the MSB. If O is 1, the byte is the
LSB
See the table below for examples on how to use binary commands.

INTEGRA User Manual Revision 1.1 7
How to Use Binary Commands
Example 1: Out of Scale Condition when Using *CEU or *CTU
If the value of these bytes is 0xFE7F, an out of scale condition exists.
INTEGRA is measuring 151 mJ in a 30 0mJ scale. The data sent by INTEGRA will be: 0x40B6
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. Shift the High byte left by 7 bits (multiply by 128)
3. Add the high and low bytes
4. Divide the result by the full scale value, 16382.
5. Multiply the result by the set scale, 300mJ.
The two data bytes are 0x40 and 0xB6. In Binary they are: 0100 0000 and 1011 0110.
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 0x36.
Shifting the high byte 7 by its results in 0x40 x 128 = 0x2000.
Adding this value to the low byte results in 0x2036, or 8246 decimal: 8246 / 16382 * 300mJ = 151mJ.
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 that it can never be the STX or ETX byte. So 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 with 0x80. If the pulse is over range, this byte is 0xFE.
Byte 5
The lower 7 data bits of the energy, or with 0x80. If the pulse is over range, this byte is 0x7F.
Byte 4
The upper 7 bits of the pulse period timer or with 0x80. (28 bits total)
Byte 3
The next 7 bits of the pulse period timer or with 0x80. (28 bits total)
Byte 2
The next 7 bits of the pulse period timer or with 0x80. (28 bits total)
Byte 1
The lower 7 bits of the pulse period timer or with 0x80. (28 bits total)
Byte 0
Always 0X03, or ETX. Let the host know this is the end of data.
Example 2: *CEU and *CTU with Out of Scale
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 exits, mask off bit 7 of each byte: 1010 0000 1011 0110 ≥ 0010 0000 0011 0110
Resulting in 0x2036, or 8246 decimal: 8246 / 16382 * 300 mJ = 151 mJ.
The pulse period bytes are 0x8080FABC. Mask off bit 7 of each byte resulting in 0x003D3C, or 15676 decimal.
The period timer is based on a 24E6 Hz clock, so the period is found as:
If you send *ceu it will be 15676 counts / 24E6 Counts per second = 653.17us.
If you send *ctu the pulse frequency will be 1 / 653.17us = 1531Hz.

4.6.3.Setup
20 - Set Personal Wavelength Correction
This command is used to specify the wavelength in nm being used on the detector. The EEPROM in the detector
contains measured spectral data for a wide range of wavelengths. If the wavelength input by the user is different
from the predefined list of wavelengths on the device, a custom value is interpolated. Specifying zero as a
wavelength or providing an out-of-bound value as a parameter restores the default settings. A valid value is set
between the lowest and highest wavelengths supported by the device, and it should not be a floating point value.
The input parameter must have 5 digits. If the desired wavelength does not have 5 digits you must enter a zero-
padded number. For example, to set the wavelength at 514 nm, you must enter 00514.
Command
Parameters
Answer

Wavelength
Default: Calibration wavelength, (typically 1064 nm, varies with the detector model)
