1 Introduction
1.1 System Description
The DAQlink III system is a multiple channel 24 bit analog to digital acquisition system. Each
DAQlink III unit can have 1 to 24 independent analog channels. Multiple DAQlink units can be
connected together for increased number of channels. The DAQlink III uses standard 10/100 Base RJ45
network connection and standard TCP/IP network protocol. The DAQlink III can be connected to any
standard network configuration.
The DAQlink III has provisions for the following options
•Two – RS232 inputs and outputs
•GPS receiver for position information
•GPS receiver for timing reference, and adjustment of internal oscillator
•Test Oscillator
•Two pre-amp gain settings
•Compact Flash for storage of acquired signals
•Multiple DAQlink units can be recorded simultaneously using standard wired or wireless
network
•Stand alone mode with GPS allows DAQlink III units to record autonomously without
user intervention.
The DAQlink III System consists of the following:
•DAQlink Unit – Digital to Analog converter unit with Ethernet interface. DAQlink-III is a 24 bit
acquisition unit, with each box containing up to 24 channels. The DAQlink III is also capable of
outputting an analog signal using a 16 bit D/A converter.
•Computer – The DAQ Link unit connects to a computer with Windows 7, Windows Vista,
Windows XP, Windows 98, Windows NT or Windows 2000 operating system and an Ethernet
Network Interface Card (NIC).
•GPS – GARMIN GPS unit
•VScope software operates on the computer and communicates to the DAQlink units. The
Software package allows viewing, analysis, and storage of the acquired signals.
•Connection cables are included to connect:
oPower (11-18 VDC)
oEthernet cable to connect DAQlink III to computer
oAnalog Input connector – Custom cables are available upon request

2.3 Multiple DAQlink III Unit Operation
Multiple DAQlink III units can be operated simultaneously. A Single DAQlink III can
used to acquire up to 24 channels, Two DAQlink IIIs are required to acquire 48 channels, while
ten DAQlink IIIs are required to record 240 channels.
The GPS receiver on each DAQlink III is normally used to synchronize the multiple
units. (The wired Trigger input can be used to synchronize multiple units if GPS signal is not
available). The GPS time of the trigger event can be sent via the Ethernet connection to all of the
DAQlink III units, if one DAQlink III unit triggers, then all of the DAQlink III units will be
commanded to trigger at the same time.
With GPS timing synchronization, the DAQlink III units only require an Ethernet
connection to acquire seismic data with multiple DAQlink III units. The Ethernet connection can
be either a “Wired” network approach or the Ethernet connection can use “Wireless” Ethernet.
Also, a combination of Wired and Wireless connections can be used to connect the multiple
DAQlink units.
The following products are available from Seismic Source to implement the Network
connection between the DAQlink III units.
“Real time” data acquisition requires an Ethernet connection between DAQlink III units.
“Passive Monitoring” or “Continuous” recording can also be setup with multiple DAQIII
units. In this mode, a network connection between the DAQlink III units is not required. The
data can be ‘Downloaded” after the recording and then processed into ‘Shot” records.
Multi-channel passive recording can be obtained by combining the downloaded records
into the Vscope software.
For Impulsive or Vibrator “shot records, the data must be “Harvested”. The exact Shot
times are used to determine the Shot records. The specific times from each DAQlink III dataset is
collected and sorted into Shot Records using the DAQlink III Harvest software.

2.3.1 Rugged 10/100 Network Switch –
Provides a 4 port network switch for connecting multiple DAQlink III units. The switch
is designed to power through the “Rugged Network cable” or direct from a battery. One Switch
is required for every 100 meters of cable; Example a 48 channel system using two 24 channel
DAQlink III units with 10 meter geophone spacing is setup. There is 240 meters between the two
DAQlink III units. This setup requires 4 network switches and quantity =3 sections of 80
meter rugged network cable. One Network switch is at Each DAQlink III unit connected to
battery power. Two more network switch units are used to connect the 80 meter cables between
the boxes (These interconnection switches are powered through the cable and do not require an
additional battery connection)
Unit is powered by +12 volt through the POE connection on the Ethernet patch cable.
2.3.2 Rugged Network Cable –
Rugged Ethernet cable with water resistance mating connectors. This switch is
designed for use with the Rugged 10/100 network Switch. Standard length is 90 meters.

13
2.3.3 DAQlink III battery box –
Rugged water resistance battery box for use with the DAQlink III system. Normally sold
with a 12 volt 20 amp hour battery. Provides connection for the DAQlink and Network telemetry
(either wired or Wireless). Also provides mounting option for Wireless network.

14 User’s Manual
2.3.4 Wireless Network Option –
This option is used to provide a wireless connection between multiple DAQlink III units.
The Wireless Option includes one Wireless Access Point and one Wireless Station. Typically
two DAQlink III units and a computer can be connected with only one Wireless Network Option.
The wireless option works well in “line of sight” operation, distances up to 2 km can operate
without any problems. However, in some areas where line of sight is limited, the Wireless
Option is also limited, and range can be limited to 50 meters or less. Multiple Wireless Network
options (repeaters) can be added to increase the range of the system.
Unit is powered by +12 volt through the POE connection on the Ethernet patch cable.

15
2.3. Ethernet Extender – Remote and Local pair–
This option is used to provide a wireless connection between multiple DAQlink III units.
The Ethernet Extender pair includes one “Local” unit and one “Remote” unit. The Ethernet data
is transmitted between boxes over a simple twisted pair cable. The distance between boxes can
be up to one mile.
Unit is powered by +12 volt through the POE connection on the Ethernet patch cable.
