1. Before You Begin

Review the warnings in this section and the best practice recommendations (see “Best

Practices” on page 50) when using and handling the WinSystems PX1-C415. Following

these recommendations provides an optimal user experience and prevents damage.

Read through this document and become familiar with the PX1-C415 before

proceeding.

1.1 Warnings

Only qualified personnel should configure and install the PX1-C415. While observing

best practices, pay particular attention to the following:.

2. Introduction

This manual provides configuration and usage information for the PX1-C415. 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 for other accessories (including cable drawings and

pinouts) that can be used with your PX1-C415.

3. Functionality

The PX1-C415 single-board computer (SBC) is a PC/104 form-factor SBC with

PCIe/104 OneBank™ expansion. The PX1-C415 features the latest generation Intel

Atom™ processors.

This unit incorporates a pair of 10/100/1000 Mbps Ethernet controllers, two SATA

ports, 24 lines of general-purpose I/O, two serial RS-232/422/485 ports with two serial

RS-232 only ports, and a watchdog timer. The SBC includes an Intel low-power Gen9

graphics engine, HD audio and video (with 3D graphics acceleration), eight USB 2.0

ports, and one USB Type-C 3.1 Gen 1 port. Expansion options are provided through the

PCIe/104 OneBank and M.2 expansion socket.

NOTE WinSystems can provide custom configurations for OEM clients. Contact an Application

Engineer for details.

FAILING TO COMPLY WITH THESE BEST PRACTICES MAY DAMAGE THE PX1-C415 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.

5. General Operation

5.1 System Block Diagram

The PX1-C415 PC/104 OneBank Intel Atom E3900 single-board computer (SBC) with

dual Ethernet provides performance for industrial IoT applications and rugged design

for demanding environments with fast, high-resolution graphics, secure data,

embedded connectivity, and expansion options. The following figure is a simplified

system block diagram of the PX1-C415.

The PX1-C415 features the Intel Atom E3900 dual core or quad core system on chip

(SOC). Its robust design, small size, and extended operational temperature make it ideal

for use in industrial IoT applications and embedded systems for industrial controls,

transportation, Mil/COTS, and energy markets.

The SODIMM memory socket provided enables up to 8 GB of ECC-capable DDR3L

RAM. An optional non-removable 8, 16, 32, or 64 GB eMMC solid-state disk provides

storage for the operating system (OS) and applications. M.2 SSD and SATA support are

also provided.

The Mini DisplayPort and LVDS display interfaces support simultaneous video output

with HD audio and stereo audio, respectively. In addition to four USB 2.0 ports, the

PCIe/104 OneBank provides two more USB 2.0 channels. The M.2 and USB 3.1 Gen 1

Type-C connectors each support an additional USB 2.0 input. There are four 16C550-

7.3 Watchdog Timer (WDT)

The PX1-C415 features an advanced watchdog timer (WDT) to guard against software

lockups; it resets the system if software does not pet the watchdog within the given

time-out period. The WDT is implemented in the ITE8528 embedded controller present

on the platform. The registers for the WDT can be accessed using the ACPI port 62/66

access mechanism. WinSystems supports the PX1-C415 WDT in the System

Management tools for the PX1-C415. Ask your sales representative for details of this

software package.

7.3.1 WDT Register Usage

In minutes mode, this register is programmed with the countdown values in minutes.

The maximum countdown time when in minutes mode is (2

- 1 minutes).

In seconds mode, this register is programmed with the countdown values in seconds.

The maximum countdown time when in seconds mode is (2

- 1 seconds).

To use the WDT, set the WDT mode bit in the configuration register to the desired mode

(seconds or minutes), then program the appropriate counter register (minutes or

seconds) with the desired countdown value. Then start the WDT by setting the

WDT enable bit in the configuration register. The WDT begins counting down in the

selected mode, and unless the WDT is disabled or reset/pet (see below), the board is

reset when the counter register is equal to 0.

To reset or “pet” the watchdog timer, rewrite the minutes or seconds counter register

with the countdown value.

To stop the WDT, clear the WDT enable bit in the configuration register.

7.4 Real-time Clock/Calendar

A real-time clock is used as the AT-compatible clock/calendar. It supports a number of

features including periodic and alarm interrupt capabilities. In addition to the time and

date-keeping functions, the system configuration is kept in CMOS RAM contained

within the clock section. A battery must be enabled for the real-time clock to retain time

and date during a power down.

WinSystems has software available for manipulating the CMOS RTC from a high-level

application.

7.5 Connectors

7.5.1 J17 - VIN Power Connector

Power is applied to the PX1-C415 via the connector at J17. Wide-range power VIN

(from 9V to 36V) is the main supply to the board.

models only). An extended temperature lithium battery is available from WinSystems,

part number BAT-LTC-E-36-16-2 or BAT-LTC-E-36-27-2.

A power supervisory circuit contains the voltage sensing circuit and an internal power

switch to route the battery or standby voltage to the circuits selected for backup. The

battery automatically switches ON when the VCC of the systems drops below the battery

voltage and back OFF again when VCC returns to normal.
