S-LINK User’s Manual Revision 2.8ii
SAFETY INFORMATION
Do not use the PC S-Link with the S-Link if the device or the detector looks damaged, or if you suspect
that the S-Link is not operating properly.
Appropriate installation must be done for water-cooled and fan-cooled detectors. Refer to the specific
instructions for more information. The user must wait for a while before handling these detectors after
power is applied. Surfaces of the detectors get very hot and there is a risk of injury if they are not allowed
to cool down.
Note: This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communication. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, we
suggest taking one or more of the following steps to correct the interference:
•Reorient or relocate the receiving antenna.
•Increase the distance between the equipment and receiver.
•Connect the equipment to an outlet that is on a different circuit than the receiver.
•Consult the dealer or an experienced radio/TV technician for help.
Caution: Changes or modifications not expressly approved in writing by Gentec-EO Inc. may
void the user’s authority to operate this equipment.

THE S-LINK DOUBLE CHANNEL LASER POWER/ENERGY METER
1.1 Introduction
To obtain full performance from the S-Link and the PC S-Link, we recommend that you read this manual
carefully.
The PC S-Link software transforms your PC screen into a large S-Link screen enabling you to control and
see your information from a distance and transfer data to a PC for sophisticated data analysis.
The S-Link is a microprocessor-based power and energy meter that uses the latest technology to provide
a multitude of options in a user-friendly environment. It is a complete power and energy meter that can
provide a statistical analysis of your measurements.
There is no need to enter the head specifications when connecting the new Gentec-EO power or energy
detector heads, for head version 5 and above. The S-Link is already internally set up to accept all the
Gentec-EO Hi power wattmeter and joulemeter heads with a DB-15 connector of head version 5 and 6.
The S-Link accepts the QE-xx-x-MT or a XLE-4.

S-LINK User’s Manual Revision 2.82
Unpacking
Each Gentec-EO S-Link is thoroughly tested and calibrated prior to shipment.
Visually inspect every S-Link unit after removing it from the shipping containers. If you see any damage,
retain all packaging materials and shipping receipts. Any damage claim should be made promptly to the
transportation company. Notify the nearest Gentec-EO representative concerning the claim, so that any
repair or replacement can be arranged as soon as possible.
You can download the latest software version for the PC S-Link (and install it on your PC) and for the S-
Link (and install it on the S-Link) with the serial interface anytime from our website www.gentec-eo.com.
You can download the PC S-Link program from our website. Go to the Downloads section of our
website: www.gentec-eo.com. Click on the file name and download it to your PC. The specific actions
necessary vary between browser and browser settings. After it is transferred, open the file on your PC
and follow the instructions to uncompress and install it. You may also consult the download instructions
document that is also in the download section of our website.

The 2.5µV bias can introduce an error into low power measurements with low sensitivity detectors. It is
essential to use the Zero Offset to rezero the S-Link before making a measurement in these conditions. It
is always good practice to use the Zero Offset. See section 2.2.

.
1- ETHERNET INTERFACE CONNECTOR (optional on S-Link):
This interface allows remote control and data transfers between the S-Link and a computer via
an Ethernet network, a wireless router or a direct connection.
2- External trigger:
The Input connector is a Female BNC. The External trigger is TTL compatible. The monitor
detects a trigger on the rising side of the external trigger signal. To measure accurately, the
trigger must be just before the laser pulse, or just after. For Example
A QE12SP-S-MT has a 20uS rise time
The External trigger must be 4 us before or 19us after the laser pulse.

S-LINK User’s Manual Revision 2.85
3- USB INTERFACE CONNECTOR :
This interface allows remote control and data transfers between the S-Link and a computer
that has a USB communication port.
4- EXTERNAL POWER SUPPLY INPUT JACK (S-Link with Ethernet option):
Input voltage required: 5-9 VDC/500 mA. If input voltage is between 15 and 25 volts the
monitor will switch to USB power or turn off. If the input power is above 26 volts either the
internal fuse will blow, or, depending on voltage level and waveform, it may damage the
monitor. When the S-Link is under power the green led will light-up. The S-link will work
under all conditions with 1 HP series high power head and all other supported Gentec-eo
heads. When you connect more than one HP series heads, you need to use the USB
power or a 5 volts- 500mA AC to DC power adapter to power the HP head.
CAUTION
Permanent damage may occur to the optical meter if an external
power supply other than the GENTEC-EO 200960 SPU15A-104 is
used. Please call GENTEC-EO or your local distributor if extra
power supplies are needed for a particular setup.
5- PROBE INPUT JACK:
The S-Link uses a DB-15 female connector to mate with the detector heads (probes).
The S-Link can take advantage of our Personal wavelength correction™. 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.
Energy detector heads prior to version 4 have a BNC connector. Contact your vendor for a
hardware upgrade.
Power detectors of version V4 and lower and Energy detectors of version V5 and lower
are not supported . Photodiodes are not supported.
