Chapter 1 Introduction
The ThinkCore DA-661/662/663 are RISC-based, ready-to-run embedded computers designed for
industrial data acquisition applications. Each model has 16 RS-232/422/485 serial ports, 1 CF
socket, 1 PCMCIA socket, and 2 USB hosts based on the Intel XScale IXP-425 communication
processor. In addition, the DA-661 has two Ethernet ports, the DA-662 has 4 Ethernet ports, and
the DA-663 has 2 fiber Ethernet channels. The casing is a standard 1U, 19-inch wide
rack-mounted rugged enclosure. The robust, rack-mountable mechanism design provides the
hardened protection needed for industrial environment applications, and makes it easy for users to
install the DA-661/662/663 on a standard 19-inch rack. The DA-661/662/663 are ideal for
applications that require a distributed embedded technology, such as SCADA systems, plant floor
automation, and power electricity monitoring applications.

Overview
The ThinkCore DA-661/662/663 are RISC-based, ready-to-run embedded computers designed for
industrial data acquisition applications. Each model has 16 RS-232/422/485 serial ports, 1 CF
socket, 1 PCMCIA socket, and 2 USB hosts based on the Intel XScale IXP-425 communication
processor. In addition, the DA-661 has two Ethernet ports, the DA-662 has 4 Ethernet ports, and
the DA-663 has 2 fiber Ethernet channels. The casing is a standard 1U, 19-inch wide
rack-mounted rugged enclosure. The robust, rack-mountable mechanism design provides the
hardened protection needed for industrial environment applications, and makes it easy for users to
install the DA-661/662/663 on a standard 19-inch rack. The DA-661/662/663 are ideal for
applications that require a distributed embedded technology, such as SCADA systems, plant floor
automation, and power electricity monitoring applications.
The DA-661/662/663 are suitable for IT control room applications, the critical assets used in the
control and automation system of industrial plant floors, and in electric power utility substations.
The DA-661/662/663 can accept a wide range of power inputs (from 100 to 240V), which means
that they can be connected to AC power lines. Because of the no hard disk, fan-less, energy
efficient design, the DA-661/662/663 minimize heat generation, can operate around the clock, year
in and year out, in heavy duty, harsh industrial environments, delivering the kind of reliable
computing power expected of a multifunctional controller.
Choose from models of the DA-661/662/663 that come pre-installed with the open-standard Linux
OS, or the commonly used WinCE OS. The built-in SDK makes program development easy by
allowing you to follow the common programming procedures used on a standard PC. All of the
software you develop for your own applications can be stored in the onboard Flash memory. The
DA-661/662/663 embedded computers are ideal for creating control systems with distributed
architecture that are based on embedded technologies. Typical applications include SCADA
systems, plant floor automation, and power electricity monitoring.

LED Indicators
LED indicators are located on the front panel of the DA-661/662/663.
LED Name Color Description
Ready Red Power is ON, and system is ready (after booting up)
Orange 10 Mbps Ethernet connectionLAN1, LAN2
LAN3, LAN4 Green 100 Mbps Ethernet connection
Orange Serial port is receiving RX data from the serial device
P1-P16 (Rx) Off Serial port is not receiving RX data from the serial device
Green Serial port is transmitting TX data to the serial device
P1-P16 (Tx) Off Serial port is not transmitting TX data to the serial device
Green
(steady on) Fiber channel is connected
FX1, FX2 Green
(flickering) Fiber channel is transmitting data
Reset Button
Press the Reset button on the front panel continuously for at least 5 seconds to load the factory
default configuration. After the factory default configuration has been loaded, the system will
reboot automatically. The Ready LED will blink on and off for the first 5 seconds, and then
maintain a steady glow once the system has rebooted.
We recommend that you only use this function if the software is not working properly and you
want to load factory default settings. To reset an embedded Linux system, always use the software
reboot command />reboot to protect the integrity of data being transmitted or processed. The
Reset button is not designed to hard reboot the DA-661/662/663.
ATTENTION
Linux OS: DA-661/662/663-LX
Pressing the Reset button will only load the configuration file. All files in the /etc directory will
revert to their factory defaults, and all user data in the Flash ROM will be deleted.
WinCE OS: DA-661/662/663-CE
Pressing the Reset button will only load the default settings (i.e., the default registry values). All
user data NOT in the Flash ROM will be deleted.
LCD Screen
The DA-661/662/663 has an LCD screen on the front panel. The LCD screen can display 16
columns and 2 rows of text. After the DA-661/662/663 boots up, the LCD screen will display the
model name and firmware version:
