DA-681 Series Hardware User’s Manual Introduction

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.

Before using a serial device that requires using a non-standard baudrate, you must first check that the DA-681 supports a baudrate within the tolerance specified by the serial device manufacturer.

Use the following formula to calculate which baudrates are supported by the DA-283: (A) Baudrate = 921600/(N+M/8) bps, for N = 1, 2, …, 18431, M = 0, 1, 2, …, 7

or (B) Baudrate = 8 x 921600/K bps, for K = 8, 9, …, 147 4 56 If you are a programmer and you need to write a driver for your serial device, then you may need

to use formula A. If you have a serial device that requires using a non-standard baudrate, then you can use formula B to determine if the DA-681 supports a baudrate within the tolerance specified by the serial device manufacturer.

Example

: Your serial device requires using a baudrate of 5340 bps and has a tolerance of 2 bps.

Can the DA-681 be used with this device ? Solution

: Set formula B to the desired baudrate and then solve for K. 8 x 912600/K = 5338 ==> K = 1367.703259… This shows that the supported baudrate closest to 5340 comes from setting K=1367 or K=1368. K=1368 ==> Baudrate1 = 5336.842105... K=1367 ==> Baudrate2 = 5340.746159… Since 5338 – Baudrate1 < 2, we can see that the DA-681 supports the serial device. Note that we can use formula A to generate the so-called “standard” baudrates, which come from

setting M=0, and setting N equal to certain integers.

Standard Baudrates

Baudrate N M Baudrate N M

921600 1 0 4800 192 0 460800 2 0 2400 384 0 230400 4 0 1800 512 0 115200 8 0 1200 768 0

DA-681 Series Hardware User’s Manual Introduction

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.

DA-681 Series Hardware User’s Manual 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.

Rack mounting

The DA-681 has rackmount supports for installing the embedded computer on a standard rack.

ATTENTIONS

1. For maximum safety, at least two persons should work together to lift, place, and attach the

embedded computer to the rack.

2. Before you lift or move the embedded computer, make sure that the embedded computer is

turned off and the power to the rack system is turned off.

Four rackmount screws are required to attach the DA-681 to a standard rack.

Rackmount screws

Follow these steps to install the DA-681 on a rack.

Step 1: Installing the rackmount supports.

Take the rackmount supports out of the packages. There are two rackmount ears and 12 screws. Each ear requires 6 screws to attach to the rack.

2-2

DA-681 Series Hardware User’s Manual 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.

Step 3: Installing the DA-681 to a rack.

Gently slide the DA-681 onto the rack, and then use screws provided by the rack supplier to fix the rackmount support to the rail.

2-3

DA-681 Series Hardware User’s Manual Hardware Installation

Note that four screws are required to attach the DA-681 to the rack. Use two screws on the left side and two screws on the right side.

As a final check, make sure that the four screws are firmly attached to the rack.

Wiring Requirements

The following common safety precautions should be observed before installing any electronic device:

y 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. y You can use the type of signal transmitted through a wire to determine which wires should be

kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can

be bundled together.

y Keep input wiring and output wiring separate. y When necessary, it is strongly advised that you label wiring to all devices in the system.

2-4

DA-681 Series Hardware User’s Manual Hardware Installation

ATTENTION

Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately.

ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and/or w iring your device. Electrical Current Caution! Calculate the maximum possible current in each power wire and common wire. Observe all

electrical codes dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious

damage to your equipment.

Temperature Caution!

Be careful when handling the unit. When the unit is plugged in, the internal components generate heat, and consequently the outer casing may feel hot to the touch.

Connecting the Power

The DA-681 offers both single power and dual power inputs. Use a screwdriver to remove the screws. Connect the power cord to the screws and then attach the screws to the unit. For single power models, use Power 1 only; for dual power models, use both Power 1 and Power 2 for power input installation. Refer to the following figure for detailed information. It will take about 30 to 60 seconds for your operating system to boot up.

Chapter 3 BIOS Setup

This chapter describes the BIOS settings of the DA-681 embedded computers. The BIOS is a set of input/output control routines for peripherals. The BIOS is used to initialize basic peripherals and helps boot the operating system before the operating system is loaded. The BIOS setup allows the user to modify the system configurations of these basic input/output peripherals. All of the configurations will be stored in the battery backed up CMOS RAM, which retainsthe system information after system reboots or the power is removed.

System Security

To set up system security, select the “Security” option under “Main” to bring up the following screen.

This menu includes two options: “Set Password” and “Security Option.” When you select the Set Password option, a pop-up “Enter Password:” window will appear on the

screen. The password that you type will replace the password stored in the CMOS memory. You will be required to confirm the new password. Just re-type the password and then press <Enter>. You may also press <Enter> to abort the selection and not enter a password.

To clear an existing password, just press <Enter> when you are prompted to enter the password. A message will show up confirming that the password will be disabled. Once the password is disabled, the system will boot and you can enter the “BIOS Setup Menu” without entering a password.

Once a password has been set, you will be prompted to enter the password each time you enter Setup. This prevents unauthorized persons from changing any part of your system configuration. In addition, when a password setting is enabled, you can set up the BIOS to request a password each time the system is booted up. The “Security Option” setting determines when a password prompt is required. If the “Security Option” is set to “System,” the password must be entered both at boot up and when entering the BIOS Setup Menu. If the password is set for “Setup,” the password prompt only occurs when you enter the “BIOS Setup Menu.”
