II Important Safety Information

The list of dangers, warnings and cautions in this section contain important information that will help ensure safe operation of the system. Please read carefully and understand all of these items. All installers, operators and maintenance personnel should read and understand this information before installation, use, or maintenance of the FDQ02T system.

The FDQ02T system by itself is not inherently dangerous. HOWEVER, WHEN THE

FDQ02T IS CONNECTED TO OTHER EQUIPMENT FOR THE PURPOSE OF CONTROL, SAFETY AND ALL POSSIBLE ASSOCIATED DANGERS MUST ALWAYS BE GIVEN THE UTMOST CONSIDERATION DURING SYSTEM INTEGRATION, DESIGN, INSTALLATION, AND USE.

The FDQ02T system may be used in virtually unlimited applications. Many of these associated systems can, by themselves, pose a mechanical, electrical or other hazard to operators and other persons or equipment. To address all possible applications and associated safety hazards in this manual would be impossible. The warnings below and throughout this manual give information that will allow safe installation and use the modem system applications. If you have questions regarding the safety of your specific application, please contact the appropriate people for help. Your Futaba sales representative, representatives of the equipment being controlled, and the technical support staff at local branch of Futaba Corporation are among those who can provide assistance with your safety concerns.

The following warnings are included in the lists that follow but warrant repetition here:

In installations where the FDQ02T system is used to control motion or operation of potentially dangerous equipment, it is imperative for safety that all operators and installers be thoroughly trained in the normal function of that equipment before attempting to control it remotely with the FDQ02T system.

To help ensure safe operation of the equipment, the FDQ02T system must be connected so that it will operate in a fail-safe way. In other words, the equipment being controlled should stop or return to its safest state in the absence of a control signal or total loss of RF transmission from the FDQ02T system. Our system uses one of the most reliable methods available to transmit data using radio signals. Many factors can affect a radio signal that may block it or interfere enough to disrupt regular transmission. Because of this, equipment motion or dangerous electrical current, for example, that continues during a loss-of-signal condition could be very dangerous.

iii

Four symbols are used in the margin of the following section and throughout the manual to indicate the level of hazard or information listed.

The symbols are defined as follows:

Indicates a hazard that will cause severe personal injury, death, or

substantial property damage if the warning is ignored.

Indicates a hazard that can cause severe personal injury, death, or

substantial property damage if the warning is ignored.

Indicates a hazard that will or can cause minor personal injury, or property damage if the warning is ignored.

Indicates installation, operation, or maintenance information that is important but not hazard-related.

Please read the following safety information carefully. Some of these notices are duplicated throughout the manual, in areas of associated content, for your benefit.

II.I General Safety Hazards and Notes

Improper installation and/or operation of the FDQ02T system can cause serious or fatal injuries to the operator or nearby persons and cause damage to the FDQ02T system, and any equipment it is used to control. Please read and understand this manual completely and the manual of all equipment being controlled before attempting to operate or install this system.

Always keep this manual at a location readily accessible to anyone operating the system and related equipment. Ensure that all operators have read and understood this manual, especially all safety and operation procedures contained in it. Please refer to the section in

this manual titled How to Obtain Help for the contact that can

supply additional manuals or answers to questions not covered in this manual. If this product is passed on to a different user, be sure that this manual accompanies the product.

Be certain that the installer of this equipment reads and understands

the instruction manual of the equipment that is being connecting to

before attempting this installation.

The FDQ02T should NOT be used in a manner in which failure of

the product or loss of the radio signal could cause damage to the

equipment being controlled, or to anything in the area in which such equipment is located. All integrated control systems should be designed for “fail-safe” operation so that a temporary or permanent loss of signal will not endanger any person, critical process, or equipment (refer to the beginning of the safety section for further explanation). The system design should ensure that the equipment being controlled will default to its safest state in the event of signal loss.

The FDQ02T contains no user serviceable parts. If the unit requires service, contact your sales representative or local branch of Futaba

Corporation per instructions the section titled How To Obtain Help. Do not disassemble or attempt to repair the FDQ02T yourself.

Doing so could void your warranty and may void the user’s authority to operate the device.

Contact Futaba before using the FDQ02T in safety critical applications such as medical equipment, aircraft, hazardous materials handling, etc.

II.II Installation Safety Hazards and Notes

When mounting the FDQ02T, use M2.6 (ISO) screws.

Use only the proper regulated DC voltage supplied to the FDQ02T. Use of any other voltage may permanently damage the modem and/or cause the modem to malfunction and create a shock or fire hazard.

Be certain that all AC power outlets used the power adapters have been properly installed, grounded, and fused. An electrical shock hazard may exist if this unit is powered by a faulty power outlet or source. If such a situation is discovered, immediately discontinue use until the power source and outlet have been properly installed, grounded, and fused by an electrician or other authorized person.

Be sure to wire the power and serial connections correctly. Incorrect wiring can damage the system, cause it to malfunction and/or create a shock and fire hazard.

Ensure that the FDQ02T power and the power to the equipment to be controlled is turned off before connecting or disconnecting the cable between them. This will help prevent accidental damage to the system and unexpected operation and/or injury.

Be sure the FDQ02T power, the power to the equipment that is being connecting to it, and the DC power source are all turned off before wiring and connecting the power cable.

Be sure that the supplied power is within the specified range (3.5 to

7.0 VDC). Voltages outside the specified range may damage the FDQ02T.

Be sure that the power source has sufficient current capacity. Insufficient current may cause the unit to malfunction.

Securely attach the antenna cable, and serial communication connector to the FDQ02T and equipment/power source to which it is connected. Failure to do so could cause an unexpected system failure.

II.III Antenna Installation Hazards and Notes

Be sure to keep all systems and antennas clear of power lines. Permanent equipment damage and severe shock injury or death can occur if the system contacts power lines.

This device has been designed to operate with an antenna having amaximum gain of 2.14 dB. Antenna having a higher gain is strictlyprohibited for use with this device. The required antenna impedanceis 50 ohms. Contact Futaba before connecting any antenna not provided by Futaba specifically for the FDQ02T. Attaching any non-authorized antenna may be in violation of FCC regulations.

To reduce potential radio interference to other users, the antenna typeand its gain should be so chosen that the equivalent isotropicallyradiated power (e.i.r.p.) is not more than that permitted for successfulcommunication.

Before each use, verify that the antenna (and antenna cable, if used) is securely attached and in good condition. A loose antenna or cable may severely reduce the operating range of the system.

The FDQ02T operates at frequencies in the 2.4 GHz band. These frequencies are more directional than lower frequencies and are easily reflected. If there are metal structures nearby, the effective range may be shortened or the directional properties may be further narrowed. To help avoid this, mount the antenna as far away as possible from surrounding metallic structures.

Multipath problems occur easily at frequencies in the 2.4 GHz band. When multipath problems are present, moving the antenna as little as 10 cm may result in improved communication or, conversely, worsened or complete loss of communication. Futaba recommends

that the mounting position of the antenna be determined after testing

and verifying optimal communication conditions.

When installing multiple FDQ02T systems that will use different frequency pattern number in the same area, these antennas must be mounted at least 6 feet (2 meters) apart. Failure to do so may severely reduce the modem operating range.

Please contact Futaba for information about antenna separation when using the FDQ02T and other wireless products in the same area.

II.IV Environmental Safety Hazards and Notes

If the FDQ02T has been stored at a temperature beyond the specified operating temperature range for the system, it may not function properly. Allow it to return to normal temperatures before use. Refer

to APPENDIX A – TECHNICAL SPECIFICATIONS for the actual

operating temperature range.

The FDQ02T is a precision electronic device with a rugged design that is intended for industrial applications. However, do not install it where it will encounter excessive vibrations. In some cases, isolation mounts may be used to isolate the modem from the equipment’s vibration. Excessive vibration can permanently damage the modem and/or cause it to malfunction.

Do not operate the FDQ02T in environments where it will be subjected to excessive moisture (such as rain or water spray), dust, oil, or other foreign matter (such as metal particles). Doing so may permanently damage the modem and/or cause it to malfunction. If it does become wet or contaminated, correct the situation, verify proper operation and have any problems corrected before using it to control other equipment. If necessary, the modem can be mounted inside a protective or waterproof enclosure. If the enclosure is metallic, the antenna must be mounted externally or the effective operating range will be severely limited.

The FDQ02T is designed for indoor use. When using it outdoors, the modem should be mounted in a waterproof enclosure and the ambient temperature range should be checked to insure that it is within the modem’s specifications. Always use the modem within its specified environmental ranges.

Operational Safety Hazards and Notes

Before each use of the FDQ02T, ensure that the area where the equipment will be operated is clear of people or obstacles that may affect its safe operation.

Before each use of the FDQ02T, verify that both the equipment being controlled and the modem are in proper operating condition.

When rewriting the FDQ02T’s memory registers, do not turn its power off until it returns a “P0” response. If the power is interrupted before a P0 response is returned, the memory contents may be lost or corrupted and it operation will be unpredictable. If the memory contents are lost or corrupted, they may be restored to original

default settings by reinitializing them. (See p.25 Memory R INITIALIZATION for more details.)

Do not attempt to operate remotely controlled equipment outside the communication range of the FDQ02T system. Doing so could cause loss of control of the equipment.

EGISTER

Without implementing proper serial communication flow control settings, the baud rate between the modem and its terminal equipment (wire linked) can exceed the wireless link data rate and cause the modem buffer to overflow. This can result in malfunction of the systems being controlled and/or data corruption. Ensure that the appropriate flow control settings are being used for your upper layer application protocol.

Exposure to Radio Frequency Radiation

For FCC RF safety requirements a miminmum of 20 cm separationdistance should be kept between the antenna and the user.

Do not operate the FDQ02T in environments where it will be subjected to excessive moisture (such as rain or water spray), dust, oil or other foreign matter (such as metal particles). Doing so may permanently damage the modem and/or cause it to malfunction. If it does become wet or contaminated, correct the situation, verify proper operation and have any problems corrected before using it to control other equipment. If necessary, the modem can be mounted inside a protective or waterproof enclosure. If the enclosure is metallic, the antenna must be mounted externally or the effective operating range will be severely limited.

WARNING

2.4.2 Antenna Installation Precautions

WARNING

CAUTION

Before each use, verify that the antenna (and antenna cable, if used) is securely attached and in good condition. A loose antenna or cable

may severely reduce the operating range of the system.

Avoid mounting the antenna near large metallic objects or inside metal enclosures. Such objects can severely reduce the operating range of the system.

The FDQ02T operates at frequencies in the 2.4 GHz band. These frequencies are much directional than lower frequencies and are easily reflected. If there are metal structures nearby, the effective range may be shortened or the directional properties may be further narrowed. To help avoid this, mount the antenna as far away as possible from surrounding metallic structures.

Multipath problems occur easily at 2.4 GHz frequencies. When multipath problems are present, moving the antenna as little as 10 cm may result in improved communication or, conversely, a further diminished or total loss of communication. Futaba recommends that

the mounting position of the antenna be determined after testing and

verifying optimal communication conditions.
