DA-681 Series Embedded Computer Introduction Dimensions Features The DA-681 Basic System has the following features: • IEC 61850-3 certified for power substation automation systems (DPP-T models only) • Intel Celeron M 1 GHz processor with 400 MHz FSB • 1 x 200-pin DDR2 SODIMM socket, supporting DDR2 400 up to 1GB (512 Mb built-in) •...
Details: See www.moxa.com/warranty Non-standard Baudrates Moxa’s UART ASIC, supports most non-standard baudrates in the range 50 bps to 921.6 Kbps. In fact, supported baudrates are much denser towards the lower values. For example, no baudrates are supported between the integers 5320 and 5323, but 49 baudrates are supported between the integers 387 and 388. Of course this is the way it should be, since serial devices that require using non-standard baudrates generally use slower baudrates.

WARNING Communication between a serial device and a Moxa UART port may not work correctly if the serial device uses a baudrate that it not within the correct tolerance of a baudrate calculated from either formula A or formula B.
Hardware Installation The DA-681 Series of embedded computers are compact and rugged, making them suitable for industrial applications. The LED indicators allow users to monitor performance and identify trouble spots quickly, and multiple ports are provided for connecting a variety of different devices. The DA-681 embedded computers come with a reliable and stable hardware platform that lets you devote the bulk of your time to application development.
DA-681 Series Embedded Computer Hardware Installation Placement Options Desktop Place your DA-681 on a clean, flat, well-ventilated desktop. For better ventilation, leave some space between the DA-681 and other equipment. Do not place equipment or objects on top of the DA-681, as this might damage the computer’s internal components.

DA-681 Series Embedded Computer Hardware Installation Step 2: Installing the rackmount ears to the DA-681. Use 6 screws to attach one rackmount ear to one side of the DA-681. Repeat this procedure for the ear on the other side of the DA-681.
DA-681 Series Embedded Computer Hardware Installation Wiring Requirements The following common safety precautions should be observed before installing any electronic device: • Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point.
DA-681 Series Embedded Computer Hardware Installation Power Input Wiring Description Read the following section for a detailed power input wiring description. Terminal Number Description Note PWR1 Line / DC + is connected to the positive (+) PWR1 Line / DC + terminal if the power source is DC, or to the Line terminal if the power source is AC.
For DC Power Input The DA-681 series low voltage DC power supply features reverse polarity protection and dual independent inputs. The dual power inputs allow the connection of two DC sources with the same nominal voltage to provide redundant power supply inputs.
DA-681 Series Embedded Computer Hardware Installation When finished, press the Power Switch button to start the system. It will take about 30 to 60 seconds for your operating system to boot up. Reset Button Pressing the Reset button initiates a hardware warm reboot. The button plays the same role as a desktop PC’s reset button.
