PET-7H16M Series User Manual, version 1.0.1 P.5
1. Introduction
The PET-7H16M is an high speed data acquisition devices built-in a Ethernet communication port
for data transfer over the network and it includes a high speed 16-bit single-ended analog inputs
(200 KHz sample and hold for 8 channels), 4-channel digital inputs and 4-channel digital outputs.
With a FIFO of 2048 samples, the maximum sampling rate is up to 200 kS/s with 8 channels 16-bit
A/D converters simultaneously sampling on each channel.
It provides programmable input range on all analog channels (±5 V and ±10 V), digital output can
be set output with Short-circuit protection and overload protection. PET-7H16M also has
qualification for 4 kV ESD protection as well as 2500 VDC intra module isolation.
PET-7H16M supports more kinds of trigger modes for A/D conversion: software trigger, external
clock trigger and external digital trigger (Post-trigger/Pre-trigger). The software trigger can acquire
a sample whenever needed, while the internal pacer saves CPU loading by triggering the sampling
at pre-programmed frequency. An external clock trigger can be used for triggering by external
frequency source.

1.1. Features
The PET-7H16M series family offers the most comprehensive configuration to meet specific
application requirements. The following list shows the features designed to simplify installation,
configuration and application.
Data transmission mode
1. Continuous transmission (Maximum sampling rate of 30 kHz per channel)
After starting A/D acquisition, data is continuously transmitted to the Host PC.
2. After collecting N data samples, the data is transferred to the Host PC (Maximum sampling
rate of 200 kHz per channel)
a. After starting A/D acquisition, the data will be temporarily stored in the memory on the
PET-7H16M module, and wait until a command is received from the Host PC, before
transferring the collected data to the Host PC.
b. The memory capacity allows temporary storage of up to 30 million data samples, Storage
time:
(b1) 125 seconds at a sampling rate of 30 kHz
(b2) 19.6 seconds at a sampling rate of 200 kHz

PET-7H16M Series User Manual, version 1.0.1 P.7
A/D trigger mode
1. Software A/D Data Acquisition mode
The A/D acquisition parameters are configured via a command from the Host PC. The
continuous A/D acquisition or the acquisition of N data samples begins after the command
is triggered.
2. External Digital Signal Event Trigger mode
The A/D acquisition parameters are configured via a command from the Host PC, and then
triggered via an external electrical signal. The A/D acquisition of the N data samples is then
started.
3. External Clock Signal Synchronization A/D Conversion Data Acquisition mode
The speed of the A/D acquisition and the amount of data acquired are controlled by external
electrical signals. A falling edge for each output waveform triggers an AD conversion

PET-7H16M Series User Manual, version 1.0.1 P.8
External Digital Signal Event Trigger mode
A/D acquisition is performed in external digital event trigger mode (triggering the electrical signal
is the falling edge trigger). The maximum sampling rate per channel is 200 kHz, and A/D
acquisition of N data samples is performed. The acquisition mode can be categorized into two
types
Pre-Trigger (acquisition of N data samples)
The A/D data is continually collected and is temporarily stored in the memory on the PET-7H16M
until the trigger signal is received. Once the trigger signal is received, the collected N data samples
are then transferred to the Host PC.
Post-Trigger (acquisition of N data samples)
In this mode, the A/D acquisition of the N data samples is started once the trigger signal is
received.

PET-7H16M Series User Manual, version 1.0.1 P.9
A/D sync trigger between multiple modules
The A/D acquisition parameters are configured via a command from the Host PC, and are
triggered by an external digital signal event, the A/D acquisition of N data samples, or A/D
acquisition via the synchronization of an external clock signal.
Built-in Web Server
Each PET-7H16M module has a built-in web server that allows users to easily configure,
monitor and control the module from a remote location using a regular web browser.

PET-7H16M Series User Manual, version 1.0.1 P.10
Communication Security
Account and password are required when logging into the PET-7H16M web server. An IP
address filter is also included, which can be used to allow or deny connections with specific
IP addresses.
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 MDI / MDI-X Crossover for Plug-and-play
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.
Software Support
1. VC, C#, VB.NET API and Demo
2. LabVIEW Toolkit and Demo

PET-7H16M Series User Manual, version 1.0.1 P.11
Highly Reliable Under Harsh Environment
PET-7H16M is housed in a metal shell/case with a column-like ventilator that helps to cool
the working environment inside the shell/case.
Operating Temperature: -25 ~ +75 °C
Storage Temperature: -30 ~ +80 °C
Humidity: 10 ~ 90% RH (non-condensing)
PoE
The PET-7H16M module has integrated Power-over-Ethernet (PoE), 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-7H16M module feature true IEEE 802.3af-compliant (classification,
Class 1) Power over Ethernet (PoE) using both Ethernet pairs (Category 5 Ethernet cable).
The PET-7H16M module 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, the PET-7H16M module can be used in a
standard Ethernet (non-PoE) system.
When using PoE devices like PET-7H16M, you can choose ICP DAS “PoE”
switch —”NS-205PSE” as the power source, NS-205PSE automatically detects the connected
devices whether they are PoE devices or not. This mechanism ensures NS-205PSE to work
with both PoE and non-PoE devices coordinately at the same time.
Being as a power source for PoE devices, NS-205PSE requires its power input ranging from
+46 ~ +55VDC.
