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, ..., 147456

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.

$$ 8 \mathrm{x} 9 1 2 6 0 0 / \mathrm{K} = 5 3 3 8 \quad = = > \quad \mathrm{K} = 1 3 6 7. 7 0 3 2 5 9 \dots $$

This shows that the supported baudrate closest to 5340 comes from setting K=1367 or K=1368.

$$ \mathrm{K} = 1 3 6 8 \quad = > \quad \text { Baudrate1 } = 5 3 3 6. 8 4 2 1 0 5... $$

$$ \mathrm{K} = 1 3 6 7 \quad = = > \quad \text { Baudrate2 } = 5 3 4 0. 7 4 6 1 5 9 \dots $$

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
921600	1	0			4800	192
460800	2	0			2400	384
230400	4	0			1800	512
115200	8	0			1200	768
57600	16	0			600	1536
38400	24	0			300	3072
19200	48	0			150	6144
9600	96		0			12288
7200	128		0		50	18432

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.

The DA-681 Series of embedded computers are compact and rugged, making them suitable for industrial applications.

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.

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.

Step 2: Installing the rackmount ears to the DA-681.

Use 6 screws to attach one rackmount car 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.

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:

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

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 wiring 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 models (SP), use Power 1 only; for dual power models (DP and DPP-T), use both Power 1 and Power 2 for power input installation. Refer to the following figure for detailed information.

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 . You may also press to abort the selection and not enter a password.

To clear an existing password, just press 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.”

Advanced Settings

The “Advanced Features” screen will appear when choosing the “Advanced” item from the main menu.

C. Rackmount Warning

The following or similar rackmount instructions are included with the installation instructions:

(1) Elevated Operating Ambient: If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than the room ambient temperature. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.
(2) Reduced Air Flow: Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.
(3) Mechanical Loading: Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
(4) Circuit Overloading: Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
(5) Reliable Grounding: Reliable grounding of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g., by using power strips).
