packages are available on the Advantech website: http://www.advantech.com/.
The Advantech Navigator is a utility that allows you to set up, configure and test
your device, and later stores your settings in a proprietary database.
1. To set up the I/O device for your card, you should first run the Advantech Navi-
gator program (by accessing Start/Programs/Advantech Automation/DAQNavi/
Advantech Navigator).
2. You can then view the device(s) already installed on your system (if any) on the
installed device tree view. If the software and hardware installation are com-
pleted, you will see USB modules in the installed devices list.
DAQNavi SDK is a software development kit for programming applications with
Advantech DAQ products. The necessary runtime DLL, header files, software
manual and tutorial videos can all be installed via XNavi installer. They can be
found under C:\Advantech\DAQNavi (default directory) after finishing the instal-
lation.
Note! The USB chip on your system may have a limitation on the number of
USB devices it will support. Normally, only five USB-4716 devices can
be supported.
Note! The power output of an USB port is 500 mA, while the USB-4716

3.3 Analog Input Connections
USB-4716 supports 16 single-ended/8 differential (or combination) analog inputs.
Each individual input channel is software-selected.
3.3.1 Single-ended Channel Connections
The single-ended input configuration has only one signal wire for each channel, and
the measured voltage (Vm) is the voltage of the wire as referenced against the com-
mon ground.
A signal source without a local ground is also called a “floating source”. It is fairly sim-
ple to connect a single-ended channel to a floating signal source. In this mode, USB-
4716 provides a reference ground for external floating signal sources.
Figure 3.2 shows a single-ended channel connection between a floating signal
source and an input channel on USB-4716.
Figure 3.2 Single-Ended Input Channel Connection

11 USB-4716 User Manual
Chapter 3 Signal Connections
3.3.2 Differential Input Connections
The differential input channels operate with two signal wires for each channel, and
the voltage difference between both signal wires is measured. On USB-4716, when
all channels are configured to differential input, up to 8 analog channels are avail-
able.
If one side of the signal source is connected to a local ground, the signal source is
ground-referenced. Therefore, the ground of the signal source and the ground of the
card will not be exactly of the same voltage. The difference between the ground volt-
ages forms a common mode voltage (Vcm ).
To avoid the ground loop noise effect caused by common-mode voltages, you can
connect the signal ground to the Low input. Figure 3-3 shows a differential channel
connection between a grounded-reference signal source and an input channel on
USB-4716. With this connection, the PGIA rejects a common-mode voltage Vcm
between the signal source and USB-4716 ground, shown as Vcm in Figure 3.3.
Figure 3.3 Differential Input Channel Connection
Note! In differential input mode, the input channel n should be used with chan-
nel n+1.
(n=0,2,4…14)

USB-4716 User Manual 12
3.4 Analog Output Connections (Voltage)
USB-4716 provides two analog output channels, AO0 and AO1. Figure 3.4 shows
how to make analog output connections on USB-4716.
Figure 3.4 Analog Output Channel Connections
3.5 Trigger Source Connections
3.5.1 Internal Pacer Trigger Connection
USB-4716 provides two 16-bit counters connected to a 10 MHz clock. Counter 0 is a
counter that counts events from an input channel. Counter 1 is a 16-bit timer for
pacer triggering. A low-to-high edge from the Counter 1 output will trigger an A/D
conversion on USB-4716.
3.5.2 External Trigger Source Connection
In addition to pacer triggering, USB-4716 also allows external triggering for A/D con-
versions. When GATE is connected to a +5V DC source, the external trigger function
is thereby disabled. The external trigger function will be enabled once the +5V DC
source is removed.
