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:
o Power (11-18 VDC)
o Ethernet cable to connect DAQlink III to computer
o Analog Input connector – Custom cables are available upon request
