SAFETY INFORMATION
Do not use the QUAD-4TRACK if the device or the detector looks damaged, or if you suspect that
the QUAD-4TRACK is not operating properly.
Appropriate installation must be done for water-cooled and fan-cooled detectors. Refer to the
specific instructions for more information. Wait a few minutes before handling the 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
B 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. If not installed and used in accordance with the instructions,
it may cause harmful interference to radio communications. 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, try to correct the
interference by taking one or more of the following steps:
• 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.
SYMBOLS
The following international symbols are used in this manual:
The QUAD-4TRACK is an advanced Beam Position Measurement system. It is used with
the Pulse Track Applications Software, which creates a full featured data acquisition
system for measuring and displaying laser energy and beam Position.
The QUAD-4TRACK is used with compatible Gentec-EO probes, the DPQ-J9, DPQ-J20,
DPQ-R9, and DPQ-R20. The J series probes are used for pulsed laser applications, and
the R series are used for Radiometric application. The QUAD-4TRACK can measure
pulsed lasers up to 1000pps on each channel when using the J series probes. When using
the R series probes the beam modulation rate can be set from 5Hz to 50Hz

drive and select OK. All the required files are on the install CD.
The software installation is now complete. You may now run the application software.
The Gentec-EO QUAD-4TRACK instrument is a PC based design. As such it comes with
a Software Application written in Lab View 8.6 designed to handle the control and
display tasks. The QUAD-4TRACK communicates with the host PC via a USB port. The
device supports full speed USB 2.0. The implementation of the port in the host PC is
accomplished via a Virtual Com Port, or VCP. This in effect mimics a standard serial port
so that the user can take advantage of the ease of developing custom applications with
existing terminal emulators. Any programming environment that can use an RS232 serial
port can communicate with the instrument.
Instrument Hardware
Power Source
The QUAD-4TRACK system is supplied with a 10V, 1.5A universal power module. It
will accept voltages from +9V to +15V provided they supply at least 1A and the plug is
5.5mm outer diameter, 2.1 mm inner diameter, and 11mm in length, with the center being
positive. Plug the supply into the DC power jack located on the front panel.
Probe Connection
The QUAD-4TRACK probes use a DB25 connector. See figure 1. To remove the probe,
power down the unit first and remove the connector.
Indicator LED’s
There are 2 LED’s on the QUAD-4TRACK back panel as shown in figure 2.
The Power LED is illuminated when ever an external supply is plugged into the DC
power jack.
The Trigger LED illuminated when the QUAD-4TRACK is triggered. This LED
functions at all times, whether the QUAD-4TRACK is sending data to the application
software or not.
USB
The QUAD-4TRACK communicates with the host PC via a USB port. The device
supports full speed USB 2.0. The host P.C must have the QUAD-4TRACK USB drivers
QUAD-4Track User’s Manual Revision 2.1 9
installed. These drivers are on the disc supplied with the QUAD-4TRACK instrument.
The Application Software is written in LabView and uses the NI-VISA software from
National Instruments to affect a communication link with the QUAD-4TRACK. The
USB cable cannot be unplugged from the QUAD-4TRACK during operation.
Analog Out
The Analog Output provides an amplified, buffered signal from the probe. A Full Scale
Reading will correspond to a 1.5V Signal at the analog out when set to a channel.
The 5th choice is a Bar Graph representing each of the 4 channels. A value of 2.000V is a
full scale representation. Each bar in the graph is approximately 50us wide.
External Trigger
QUAD-4TRACK supports internal and external triggering. Connect a TTL trigger signal
to this input to use external triggering.
Turning the Unit On
Before turning the QUAD-4TRACK on, be sure that the probe in use is plugged in. When
the QUAD-4TRACK powers up, it reads the probe memory to obtain required
information for correct operation. QUAD-4TRACK cannot detect a probe removal, so hot
swapping the probe is not permitted. Doing so will not cause damage, but the probe
information will not be updated. Once the probe and power supply are connected, turn the
unit on by setting the Power Switch to ON. The Power LED will illuminate. The QUAD4TRACK is now ready to use.
Power on Tests
When powered on, the QUAD-4TRACK tests its internal memory and its control
circuitry to ensure it can accurately measure data. If the internal memory fails its test, the
QUAD-4TRACK will not turn on the Power LED. Should this condition occur, contact
Gentec-EO at 503-697-1870 for service of the unit.
The Applications Software
Welcome to the PDQ-4-DPM Pulse Track Software Application Software. This software,
when coupled with a Gentec-EO PDQ-4-DPM Instrument, provides the user with a
versatile measurement system.
The Applications Software communicates with the host PC via a USB port. The system
uses the QUAD-4TRACK Command Set to do this.
The QUAD-4TRACK sends the measured data to the Applications Software when
requested to do so. The software will then display the data from each of the 4 channels.
QUAD-4Track User’s Manual Revision 2.1 10
Communications with Host PC
The QUAD-4TRACK Instrument communicates with the host PC via a USB port. The
device supports full speed USB 2.0. The host P.C must have the QUAD-4TRACK
Instrument USB drivers installed. These drivers are installed by the disc supplied with the
QUAD-4TRACK Instrument. The Application Software is written in LabView and uses
the NI-VISA software from National Instruments to affect a communication link with the
QUAD-4TRACK Instrument. The implementation of the port in the host PC is
accomplished via a Virtual Com Port, or VCP. This in effect mimics a standard com port
so that the user can take advantage of the ease of developing custom applications with
existing terminal emulators.
The Ports Settings are:
Baud Rate : 115200
Data Bits : 8
Stop Bits : 1
Parity : None
Flow Control : None
The host PC must have the QUAD-4TRACK USB drivers installed. These drivers are
installed by the disc supplied with the QUAD-4TRACK instrument. The QUAD4TRACK instrument will use the highest available PC baud rate. PC’s running a
language that uses an alphabet such as English generally will have a maximum baud rate
of 921600. PC’s using a symbol based language such as Japanese run slower baud rates,
usually with a maximum of 115200. This restriction drives the maximum rate used in the
QUAD-4TRACK.
Data Format
Measurement Data is sent from the QUAD-4TRACK Instrument as a Hexadecimal
string. The supplied LabView VIs parse this data into numeric values.
Pulse amplitude for each channel, Measurement Range, and time stamp information are
sent.
The format is: AAAAAAAAAAAARPPPPPPPPCRLF
Where AAA is the pulse amplitude in ADC counts, for each of the 4 channels. R is the
range index of the range used to measure the data. PPPPPPPP is the pulse time stamp.
The values are followed by a carriage return and a line feed.
The final byte of the pulse amplitude consists of 4 bits of data in the high nibble,
followed by 0x04, the end of transmission character, in the low nibble. This is dome
because the data is sent over the com port, and is also sent to the secondary processor.
