1. Introduction
The PET-AR400 is a high speed data acquisition device. The PET-AR400 built-in an Ethernet
communication port for data transfer over the network and includes 4 IEPE inputs (128 kHz for 1
channel; 32 kHz for 4 channels) for measuring the signal from an IEPE accelerometer.
The PET-AR400 also provides 4 kV ESD protection as well as 2500 VDC intra-module isolation. In
addition, the 24-bit ADC includes built-in Sinc3 filtering to adjust the appropriate sampling rate and
filter out modulator and signal noise.
The PET-AR400 is not only suitable for a wide range of mobile/portable measurement applications,
but also for precision signal measurement.
PET-AR400 supports many kinds of trigger modes for A/D conversion：software trigger, analog
threshold trigger. The software trigger can acquire a sample whenever needed; The analog
threshold trigger will collect data while the analog input value is higher or lower than specific
voltage value.

1.1. Features
The PET-AR400 module offers the most comprehensive configuration to meet specific application
requirements. The following list shows the features designed to simplify installation, configuration
and application.
Data Acquisition Mode
1. Continuous Acquisition Mode
After starting A/D acquisition, data is continuously transmitted to the Host PC.
2. N-samples Acquisition Mode
a. After starting A/D acquisition, the data will be temporarily stored in the memory and
wait until the host PC send a transmit command, once the module received the
command, it start transferring data to the host PC.
b. The memory capacity allows temporary storage of up to 15 million data samples.

A/D Trigger Mode
1. Software trigger mode
After the acquisition parameters are configured by the PC and the trigger command is send,
the A/D starts to acquire data.
2. Analog threshold trigger mode
After the acquisition parameters are configured by the PC and the start command is send, the
A/D waits for the input voltage signal to meet the trigger condition, after the signal reach the
condition, it starts to collect data
The analog threshold trigger can be used to detect the instantaneous change in a continuous
voltage signal.
The user can specify the trigger condition and range.
1. Above High：A/D starts to acquire data, once the signal is higher than the high level.
2. Below Low：A/D starts to acquire data, once the signal is lower than the high level.

3. Leave-region：A/D starts to acquire data, once the signal is out of range.
4. Entry-region：A/D starts to acquire data, once the signal is in the range.
Modbus/TCP Protocol
The Modbus/TCP slave function on the Ethernet port can be used to provide data to remote
HMI/SCADA software built with Modbus/TCP driver.
Automatic MD/MDI-X Crossover for Plug-and-play MDI/MDI-X
RJ-45 port supports automatic MDI/MDI-x that can automatically detect the type of connection
to the Ethernet device without requiring special straight or crossover cables.

PoE
PET-AR400 feature true IEEE 802.3af-compliant (classification, Class 2) Power over Ethernet (PoE)
using both Ethernet pairs (Category 5 Ethernet cable), it allows power and data to be carried
over a single Ethernet cable, so a device can operate solely from the power it receives through
the data cable.
This innovation allows greater flexibility in office design, higher efficiency in systems design, and
faster turnaround time in set-up and implementation.
The PET-AR400 can receive power from an auxiliary power sources like AC adapters and battery
in addition to the PoE enabled network.
This is a desirable feature when the total system power requirements exceed the PSE's(power
sourcing equipment) load capacity. Furthermore, with the auxiliary power option, PET-AR400
can be used in a standard Ethernet (non-PoE) system.
PoE Switch
NS-205PSE-24V
When using PoE devices like PET-AR400, user can choose ICP DAS“PoE
switch”—“NS-205PSE-24V”as the power source, it can automatically detect the connected
devices whether they are PoE devices. This mechanism ensures NS-205PSE-24V to work with
both PoE and non-PoE devices coordinately at the same time.

Step 3：Mount the ground screw and wiring the ground cable
Tips & Warnings
A good ground reference (earth ground) is essential for proper operation of the
PET-AR400. One side of all control circuits, power circuits and the ground lead
must be properly connected to earth ground by either installing a ground rod in
close proximity to the enclosure or by connecting to the incoming power system
ground. There must be a single-point ground (i.e. copper bus bar) for all devices
in the enclosure that require an earth ground.
