1 Voltage bias can introduce an error into low power measurements with low sensitivity detectors. It is essential to use the Zero Offset to re-zero the U-Link before making a measurement in these conditions. It is always good practice to use the Zero Offset. 2 Varies with detector head. 3 Including linearity.
4 This is PC dependent. The host PC must be fast enough to receive and process incoming data. Recommended: Intel Duo Core processor with a 2.4GHz clock speed or better.
1.3.1. External trigger timing requirements
The beginning of the external trigger signal must arrive in a time window
relative to the beginning of the laser pulse. This window begins 20% of the
rise-time before the laser pulse and ends one rise-time after the beginning of
the pulse minus the minimum trigger pulse width. Example for QE12LP-H-MB
Detector Head: The following value is found in the Detector Head user manual.
Signal rise-time = 550 sec 20% of rise-time = 550 X 20% = 110 sec Rise-time
minus minimum trigger pulse width = 550 1 = 549 sec Therefore, the
acceptable window for the beginning of the external trigger pulse is from 110
sec before the laser pulse begins to 549 sec after the laser pulse begins.
Incorrect energy measurements may result if the trigger pulse arrives outside
of this window.

ANALOG OUTPUT
For monitoring laser average power or energy by using external equipment such as a chart recorder, a computer with an analog interface, a voltmeter, etc. Use this port with Gentec-EO Part Number 100-201958 Analog Out Cable for this feature.
The output signal represents a DC analog voltage proportional to the amplified and anticipated power detector response in the case of a power measurement. In the case of an energy measurement, the output signal is a DC voltage representing the pulse energy value.
The user must enter the maximum output voltage and the maximum power/energy scale in the PC-GentecEO software or via serial commands. The measured power or energy is then scaled to the output voltage and to the selected range according to the following equation:
Voutput = ( Measurement × Max Output Voltage ) / Max Analog Out Range For example, with a 10 W max analog range and 2.0V max output voltage:
2.0 V corresponds to 10 W 1.0 V corresponds to 5 W
Another useful example: To set the analog output so that 1V corresponds to a measurement of 56W, with a maximum output voltage of 2V, the Max Analog Out Range must be set to 112W according to the following equation:
Max Analog Out Range = 56 × 2.0 = 112
Specifications on the analog output:
Maximum output voltage: Connector type: Full-scale accuracy:

TRIGGER INPUT The U-LINK USB allows connection to an external trigger input
for energy measurements. Use Gentec-EO Part Number 201956, which has a Male
BNC connector, for this input. Refer to section 1.3.1. External trigger timing
requirements for timing requirements. SYNC OUTPUT The U-LINK USB can trigger
another U-LINK USB via its Sync Output. Use Gentec-EO Part Number 205117 and a
BNC cable to connect two U-LINKs together. The U-LINK with the Sync Output
enabled must be in Self-Triggered Energy Mode. When it detects an energy
pulse, it will send a signal via its Sync Output connection to the other
U-LINK in External Triggered Energy Mode, starting a measurement on the other
U-LINK. The Sync Output signal should only be connected to the External
Trigger Input of another GentecEO U-Link energy monitor.
EXTERNAL POWER SUPPLY INPUT JACK
Input voltage required: 9-12 VDC/200 mA. Note: The external power supply input
is provided only for the U-LINK with the RS-232 Serial Connection Option.
Permanent damage may occur to the device if an external power supply other
than the GENTEC-EO 200130, 200960, SPU15A-105 or SPU15A-104 is used. Please
call GENTEC-EO or your local distributor if extra power supplies are needed
for a particular setup.
U-LINK User Manual

DETECTOR HEAD INPUT JACK
The U-LINK uses a DB-15 female connector to mate with the detector heads
(probes). The U-LINK works with all Gentec-EO power and energy detectors that
have this DB-15 connector, except certain, older THz-D models with an
incompatible DB-15 head. It automatically recognizes every power or energy
detector head, which ensures accurate auto-calibration. More importantly, it
can take advantage of our Personal wavelength correctionTM. It reads the
memory in the Smart Interface connector (version 5 and higher) to provide a
wavelength correction that is based on spectral data measured from that
specific detector. The U-LINK may not recognize some of the earlier heads.
This DB-15 connector, though similar to that of the former TPM-310 and TPM-330
monitors, is incompatible with the power detector heads of PS-310 Series
Version 1 and PS-330 Series Version 1. These heads used a different technology
and do not have the same pin-out configuration.
The GENTEC C-300 adaptor can be used in order to connect the power detector
heads of PS-310 Series and PS-330 Series Version 1 and 2. Please contact your
local Gentec-EO distributor or the nearest GentecEO office for further
information. Any attempt to modify connectors of the early version heads to
mate with the U-LINK can result in damage to the device. Note the U-LINK RS232
model does not support THz-B V2 Series detectors due to the chopper
synchronization signal required for these detectors.
2. OPERATING INSTRUCTIONS
First, install the PC-Gentec-EO software on your computer, along with the USB
drivers. Please find the latest version on our website (www.gentec-eo.com) in
the Downloads section. The software will list the attached Gentec-EO devices
available to connect. As soon as you are connected, you are ready to adjust
the settings (please refer to the PC-Gentec-EO manual).
2.1. INSTALLING THE USB DRIVER
Plug the U-LINK into a USB port on the PC. If the PC supports USB 1.1, Windows
detects the new device and prompts you for the software drivers. A window will
open that says “Found New Hardware USB Device” and after a few moments, the
“Found New Hardware Wizard” will appear. The USB drivers are available on our
website (www.gentec-eo.com) in the Downloads section At the end of this
process, a new serial COM port will be added to the list of communication
ports. It may be used as any other serial port. The COM port will then be
listed in the PC-Gentec-EO software. Verify COM Port To verify the USB
installation and find the COM port number, open the device manager and 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.
2.2. QUICK MEASUREMENT PROCEDURE
This section will show you how to make a laser power or energy measurement
with U-LINK and a GentecEO power or energy detector.
U-LINK User Manual
Revision 1.5
14
U-LINK automatically recognizes all the Gentec-EO power heads and energy heads
of version 5 or higher. All customized technical data required for optimum
operation of the detector will be automatically downloaded from the EEPROM in
the DB-15 connector. These data include all the necessary head parameters such
as sensitivity, model, serial number, version, wavelength correction factors,
time response and others. U-LINK doesn’t support energy detectors before
version 5.
Quick power and energy measurement procedure: 1. Install the PC-Gentec-EO
software on your PC. Also install the U-LINK drivers. 2. Install the power or
energy detector head on its optical stand. 3. First, slide the connector latch
to the right to unlock the connector. 4. Connect a compatible power or energy
detector head to the U-LINK using the PROBE INPUT JACK (see previous
Connections section). The U-LINK allows hot-swapping between heads. 5. Slide
the latch to the left to lock the connector into place. 6. Connect U-LINK to
your computer via USB. 7. Start the PC-Gentec-EO software. Click the Connect
button in the top left corner and select your U-LINK from the list of devices
that appear. 8. 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. Remove the head’s protective cover
and start the laser. 9. 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.
Power heads can be used with both CW and pulsed lasers. Energy heads can only
be used with pulsed lasers.
Adjusting the zero (step 10-A for power heads and 10-B for photodiode heads)
10. The power read by the U-LINK when no laser beam is incident on the
detector may not be exactly zero. For power measurements, this is because the
detector is not thermally stabilized and/or there is a heat source in the
field of view of the detector. For photodiode measures, zeroing will remove
the detector’s offset. a. Block off laser radiation to the detector. To reset
the zero, wait until the reading has stabilized and click Zero in the toolbar
ribbon. The zero will be taken for all scales in AutoScale mode or for the
current scale if you have selected a scale. b. If you have connected a
photodiode to U-LINK, you must cover the diode. Click Zero in the toolbar
ribbon and the zero offset will be taken for all scales.
Notes: · Refer to specific power detector documentation for complete
installation and operating instructions. · Power detectors are thermal sensors
and are thus sensitive to temperature variations. · For high-precision
measurements, it is recommended to: o Allow the power detector temperature to
stabilize before zeroing. o Touch only the stand when handling the power
detector. Do not touch the detector head. o Do not zero energy detectors, such
as the QE series. o Avoid forced airflow or drafts around the detector. 11.
Apply the laser beam to the detector head. 12. The laser beam average power or
energy can be displayed in several ways for your convenience: a. Digitally for
real time measurements; b. On a scope graph to evaluate the laser’s variations
in time; c. On a digitally produced analog display using a needle for easy
visualization of the laser beam power variation during laser fine-tuning; d.
Averaged over a certain number of measurements; e. Complete statistical
results over a certain period of time.

4. SERIAL COMMUNICATION
4.1. DESCRIPTION
The U-LINK has two main communication modes: binary mode for fast data
acquisition and ASCII mode for human-readable output. Both modes require text
input commands which must follow rules stated in this section.
The USB class used by U-LINK USB 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 as if it were an RS232
port, and take advantage of faster speeds offered by USB. 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 irrelevant, so leave them at
whatever default they are in. It’s a real USB connection. The U-LINK RS232
features a typical RS232 port and port settings do have an effect. Be sure to
use the correct settings, indicated later in this section.
4.2. SETTING UP COMMUNICATION TO THE U-LINK
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 Serial Device (COM#) Note the COM port number, you will need it for the
next step.
4.2.2. Connect the U-LINK
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. The installation of HyperTerminal will not be covered in this manual.
Start HyperTerminal.
To save communication settings, enter a name for the connection. In 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.

File Properties Settings ASCII setup “Echo typed characters locally” OK In the
HyperTerminal window, type VER. If the response is the version of your
U-LINK, you are successfully connected and ready for serial command action. In
some cases, the U-LINK has connection problems that can be solved by adding a
character delay. To adjust this delay, click the File menu and execute the
following sequence:
File Properties Settings ASCII setup “Character delay”: add a few milliseconds
of delay OK 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
Commands are sent as text strings. The response will either be data or an
empty string. All text commands must begin with a trigger 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 capitalized; mixed
upper and lower cases are ok. Replies to all text mode commands are also in
text mode, and end with a carriage-return and a line-feed. 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
4.4. BINARY MODE OUTPUT FORMAT
The U-LINK’s resolution is 12-bit for Joulemeter mode. To keep compatibility
with other Gentec-EO monitors, a 14-bit value is sent, but the two LSB of the
low byte are non-significant. Only the Joulemeters support the binary mode.
Thermopiles in energy mode, thermal heads in standard mode and Photo Detectors
output only in ASCII. By default, the Joulemeters are in ASCII mode. To turn
on the binary mode, send the command

Decoding CAU or CVU If you send CAU, U-LINK will send continuous data with
2 bytes per pulse. If you send CVU, U-LINK 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 (MSB). If the Order Bit is 1, the byte is the low byte (LSB). You must then mask out the Order Bit, shift the MSB, add the two bytes, and apply scaling. See example below.
The 2 bytes are decoded as follows: High byte: 0XXX XXXX in binary 0 indicates this is the High byte and X is the upper binary data. If the measurement is over-range, this byte is 0xFE.
Low byte: 1XXX XXYY in binary 1 indicates this is the Low byte, X is the lower binary data and Y is non-significant data. Y will always be 0 for measurement data. If the measurement is over-range, this byte is 0x7F.
Example 1: Using CAU or CVU U-LINK is measuring 151 mJ in a 300mJ scale. The
data sent by U-LINK 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 (logical AND with 0x7F). 3.
Shift the high byte left by 7 bits (multiply by 128 as a 16-bit value). 4. Add
the high and low bytes (logical 16-bit OR) 5. Switching to floating-point,
divide the result by the full-scale value, 16382. 6. Multiply the result by
the set scale, 300mJ.
The two data bytes are 0x40 and 0xB4. In binary they are: 0100 0000 and 1011
0100. The 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 0xB4. The data is the lower 7 bits
of each byte, or high byte of 0x40 and low byte of 0x34. Shifting the high
byte by 7 results in 0x40 × 128 = 0x2000. Adding this value to the low byte
results in 0x2034, or 8244 in decimal. Dividing by the full-scale value “300
mJ / 16382”, we get: ( 8244 / 16382 ) × 300mJ = 151mJ.
If the value of these bytes is 0xFE7F, an out-of-scale condition exists.
Decoding CEU or CTU If you send CEU or CTU U-LINK will send data with 9
bytes per pulse.
The 9 bytes are decoded as follows: Byte 8 Always 0x02, which is ASCII STX.
Lets the host know this is the start of data. Byte 7 The scale index, OR’d
with 0x80. This is done so that it can never be the STX or ETX byte. 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 range, this byte is 0xFE. Byte 5 The
lower 7 data bits of the energy, OR’d with 0x80. If the pulse is over 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, which is ASCII ETX.
Lets the host know this is the end of data.
Example 2: Using CEU and CTU U-LINK is measuring 151 mJ in a 300 mJ scale.
The pulse frequency is 20 Hz. The data sent by U-LINK will be:
0x0297A0B681DBDAFC03.
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 0x97A0B681DBDAFC 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
U-LINK User Manual
Revision 1.5

The scale byte is 0x97. Mask off bit 7 results in 0x17, or 23 in decimal. Refer to the scale table in the serial commands section. Scale number 23 is 300mJ. The energy data bytes are 0xA0B6. If these bytes are 0xFE7F, an out of scale condition exists. If no out of scale condition exits, mask off bit 7 of each byte, then follow steps 3 to 6 of the procedure to decode *CAU readings.
The pulse period bytes are 0x81DBDAFC. Mask off bit 7 of each byte, shift and
OR the bytes in order resulting in a 28-bit value, in this case 0x36ED7C, or
3599740 in decimal. The period timer is based on a 72 MHz clock, so the period
is found as:
3599740 counts / 72×10^6 counts per second = 49.9s The pulse frequency will be
1 / 49.9s = 20Hz.
4.5. LIST OF SERIAL COMMANDS FOR THE U-LINK
Note: U-LINK also supports M-LINK and T-RAD legacy commands for software
compatibility. Please refer to the user manuals for those products for a list
of legacy serial commands. Also note that the detector heads compatible with
T-RAD cannot be used on the U-LINK. Only Version 2 THZ-B Series heads can be
used with U-LINK. Any attempt to modify a detector head, cable, or monitor, or
use of a modified detector with a monitor, will void the warranty.

If the desired wavelength does not have 5 digits you must enter a zeropadded number. For example, to set the wavelength at 514 nm, you must enter 00514. Specifying zero as a wavelength or providing an out-of-bound value as a parameter has no effect.
Command PWC
Parameters Wavelength nm

*AVG – Noise Suppression Averaging
Sets the sampling size of the noise suppression. For pyroelectric detectors
and UM detectors only.
The joulemeter mode has a special proprietary algorithm that can lower the
noise-induced error when reading low energy levels, or energy readings of any
level with noise present. This feature greatly reduces the effect of noise on
the peak-to-peak measurement in joulemeter mode. The monitor will need to
measure the number of pulses selected in the Sampling Size before the
algorithm will settle to the noise suppressed value. Once the readings have
stabilized, any subsequent reading will be stable until the Sampling Size is
changed. The system will then stabilize to the new value. Larger sampling
sizes will result in more noise suppression. Noise suppression works best with
the external trigger. This function will greatly improve the accuracy of the
lowest scale or in any scale when used in a noisy environment.
The parameter must consist of exactly 3 digits.

Performance Criteria
As shown Criteria A
Table 11 Performance Criteria Performance Criteria
Description
Criteria A
The DUT does not have any noticeable deviations in its performance before, during or after the application of the EMC test. If a range of performance is specified as normal operation, the DUT did not have any readings outside of this range before, during or after the application of the EMC test.
Criteria B
The DUT does not have any deviations of performance before or after the
application of the EMC test, but during the application a deviation is noted
that is not considered normal operation. When the EMC test is paused or
completed the DUT recovered on its own and did not require any user
intervention to return it to normal operation.
If a range of performance is specified as normal operation, the DUT’s
performance was outside of this range during the application of the test, but
recovered on its own and operated within its normal range after the
application of the EMC test.
No permanent damage occurred to the DUT or any AE as a result of the
disturbance.
Criteria C
The DUT was operating normally before the application of the EMC test, but during the application, the DUT stopped operating normally, and did not recover after the application of the EMC test until an operator intervened. This includes but is not limited to: – Power cycling the DUT, – Restarting the exercising software on the DUT, and – Unplugging and re-plugging the DUT or any AE The act of “recovering” the DUT must be something that could be accomplished by the customer with little training. No permanent damage occurred to the DUT or any AE as a result of the disturbance.
Additional Criteria
No incorrect data recorded while logging:
U-Link with Thermal Detector XLP12-3S-H2-DO measuring 420mJ ± 5mJ U-Link
with Optical Detector PH100-SI-HA-DO measuring 100W ± 1W U-Link with Energy

application of the EMC test. No permanent damage occurred to the DUT or any AE
as a result of the disturbance.
Criteria C
The DUT was operating normally before the application of the EMC test, but
during the application, the DUT stopped operating normally, and did not
recover after the application of the EMC test until an operator intervened.
This includes but is not limited to: – Power cycling the DUT, – Restarting the
exercising software on the DUT, and – Unplugging and re-plugging the DUT or
any AE
The act of “recovering” the DUT must be something that could be accomplished
by the customer with little training. No permanent damage occurred to the DUT
or any AE as a result of the disturbance.
