1. Before You Begin
Review the warnings in this section and the best practice
recommendations (see “Best Practices” on page 11) when using and
handling the WINSYSTEMS PX1-I440-ADC. Following these
recommendations provides an optimal user experience and prevents
damage. Read through this document and become familiar with the PX1-
I440-ADC before proceeding.
1.1 Warnings
Only qualified personnel should configure and install the PX1-I440-ADC.
While observing best practices, pay particular attention to the following:.
2. Introduction
This manual provides configuration and usage information for the PX1-
I440-ADC. If you still have questions, contact Technical Support at (817)
274-7553, Monday through Friday, between 8 AM and 5 PM Central
Standard Time (CST).
Refer to the WINSYSTEMS website at http://www.winsystems.com/ for
other accessories (including cable drawings and pinouts) that can be used
with your PX1-I440-ADC.
3. Functionality
The PX1-I440-ADC is an industrial data acquisition module for embedded
systems with PCIe/104 OneBank™ expansion. This module features eight
differential analog-to-digital converter (ADC) inputs based on Analog
Devices’ LTC2335-16 ADC. Analog to digital inputs terminate to a single 16-
pin box header. The PX1-I440-ADC provides flexible voltage ranges from
0 V to 5 V, 0 V to 5.12 V, ±5 V, ±5.12 V, 0 V to 10 V, 0 V to 10.24 V, ±10 V, and
±10.24 V.
The PX1-I440-ADC-420 configuration includes precision resistors on board
for measuring 4-20 mA current loop inputs from a variety of sensors.
FAILING TO COMPLY WITH THESE BEST PRACTICES MAY DAMAGE THE PX1-I440-
ADC AND VOID YOUR WARRANTY.
Avoid Electrostatic Discharge (ESD)
Only handle the circuit board and other bare electronics when electrostatic
discharge (ESD) protection is in place. Having a wrist strap and a fully grounded
workstation is the minimum ESD protection required before the ESD seal on
the product bag is broken.

6.2 Connectors
6.2.1 J2 - ADC Input Header
The ADC Input header provides eight channels of analog to digital inputs
as well as a a sample clock rate. This clock is free running, but does reset
at the start of a conversion command.

• TE Connectivity 1658622-4, 0.1” pitch
6.2.2 JP1 and JP2 Voltage Test Jumpers
JP1 and JP2 are test jumpers that input on-board voltages to the ADC pins.
This is to allow software testing to verify that the ADC and software are
working as intended.
NOTE DO NOT provide ADC inputs on connectors J2 or J3 when using onboard
jumpers at JP1 or JP2.
