SYS-427/Before You Begin
v1.0 www.winsystems.com Page 5
1. Before You Begin
Review the warnings in this section and the best practice
recommendations (see “Best Practices” on page 36) when using and
handling the WINSYSTEMS SYS-427 embedded computer. Following these
recommendations provides an optimal user experience and prevents
damage. Read through this document and become familiar with the SYS-
427 before proceeding.
1.1 Warnings
Only qualified personnel should configure and install the SYS-427. While
observing best practices, pay particular attention to the following:.
2. Introduction
This manual provides configuration and usage information for the SYS-
427. 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 SYS-427.
3. Functionality
The SYS-427 is a rugged, embedded computer featuring the latest
generation Intel Apollo Lake-I SOC processor.
This full-featured embedded computer supports three independent video
displays (two DisplayPort and one LVDS video), dual Ethernet, two USB 3.1
Gen 1 ports, four USB 2.0 ports, eight general purpose I/O (GPIO) lines, two

Platform Module (TPM 2.0)
FAILING TO COMPLY WITH THESE BEST PRACTICES MAY DAMAGE THE SYS-427
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.

8.2 System Mounting Options
WINSYSTEMS provides optional brackets and DIN rail mounting hardware
for mounting the SYS-427 rugged enclosure to your system. See the
diagram below for hardware type and product part numbers.
8.3 Watchdog Timer (WDT)
8.3.1 WDT Register Usage
The Watchdog Timer (WDT) implemented in the SYS-427’s embedded
controller (EC) can be used to reset the system if a lock-up prevents a
software task from periodically resetting the watchdog timer. The WDT is
controlled through a set of virtual registers that are exposed to Apollo
Lake applications by the EC on the SYS-427. The WDT can be programmed

to count in either seconds or minutes; it has a minimum granularity of 1
second, and a maximum granularity of 255 minutes.
8.4 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.
8.5 System Management Software
The system management software for the SYS-427 consists of a set of
library functions and example applications that demonstrate the
functionality of the system management software. The software is
available for both Windows 10 and Ubuntu Linux.
The system management software is custom software designed to use the
built-in functionality of the SYS-427’s embedded controller (MicroChip
MEC1418) to perform system management tasks such as reporting of
board voltages (3.3 V, 5 V, 12 V, Vddq, Vcore, Vbat, and the pair of user ADC
inputs), the control of the system fan, reporting of the ambient
temperature and setting of temperature sensor thresholds. Additional
functionality allows applications to determine the version of the EC
firmware, report the boot image used when the system started, and allow
the EC to update its own firmware image. The EC contains a pair of
identical images for redundancy and rolls over to a correct image if the
first image is compromised.
