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 FRH-SD07TU/TB system.
The FRH-SD07TU/TB system by itself is not inherently dangerous. HOWEVER, WHEN
THE FRH-SD07TU/TB 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 FRH-SD07TU/TB 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 FRH-SD07TU/TB 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 FRH-SD07TU/TB system.
To help ensure safe operation of the equipment, the FRH-SD07TU/TB 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 FRH-SD07TU/TB 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.

Page iv FRH-SD07TU/TB Manual
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 FRH-SD07TU/TB modem 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 FRH-SD07TU/TB modem 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 FRH-
SD07TU/TB yourself. Doing so could void your warranty and may
void the user’s authority to operate the device.
Contact Futaba before using the FRH-SD07TU/TB modem in safety
critical applications such as medical equipment, aircraft, hazardous
materials handling, etc.
II.II Installation Safety Hazards and Notes
When mounting the FRH-SD07TU/TB modem, use M2 (ISO) screws
that project 2 to 3 mm into the modem. Screws that project further into
the modem (3.5mm MAX) may permanently damage the internal
components and/or cause the FRH-SD07TU/TB modem to
malfunction.
Use only the proper regulated DC voltage supplied to the FRHSD07TU/TB modem. 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
Rev. 050415-01.1
Page v
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 FRH-SD07TU/TB modem 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 FRH-SD07TU/TB modem 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 (2.7 to
3.3 VDC). Voltages outside the specified range may damage the FRHSD07TU/TB modem.
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 FRH-SD07TU/TB modem 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.
Contact Futaba before connecting any antenna not provided by Futaba
specifically for the FRH-SD07TU/TB modem. Attaching any nonauthorized antenna may be in violation of FCC regulations.
Futaba Corporation Rev. 050415-01.1
Page vi FRH-SD07TU/TB Manual
When using two antennas with a single FRH-SD07TU/TB modem for
diversity reception, mount the antennas as far apart as possible (6 cm
minimum). If the antennas are too close, the diversity advantage will
not be achieved.
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.
When installing the FRH-SD07TU/TB modem in a mobile unit such
as an Automated Guided Vehicle (AGV), Futaba recommends to use
the diversity reception feature as a remedy for multipath fading
problems. For diversity reception, install the two antennas as far apart
as possible in order to gain maximum benefit (6 cm minimum).
The FRH-SD07TU/TB 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. Negative multipath
effects can also be overcome with antenna diversity. See p.12
DIVERSITY ANTENNA SETUP and the related register settings for more
details regarding antenna diversity function.
When installing multiple FRH-SD07TU/TB modem systems that will
use different frequency groups in the same area, modem’s antennas of
different frequency groups 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 FRH-SD07TU/TB and other wireless products in the same
area.

II.IV Environmental Safety Hazards and Notes
If the FRH-SD07TB/TU modem 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 FRH-SD07TB/TU modem 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 FRH-SD07TB/TU modem 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 FRH-SD07TU/TB 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.

Caution
Exposure to Radio Frequency Radiation
For FCC RF safety requirements a miminmum of 20 cm separation
distance should be kept between the antenna and the user.
Operational Safety Hazards and Notes
Before each use of the FRH-SD07TU/TB modem, 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 FRH-SD07TB/TU modem, verify that both the
equipment being controlled and the modem are in proper operating
condition.
When rewriting the FRH-SD07TB/TU modem’s memory registers, do
not turn the modem’s power off until the modem returns a “P0”
response. If the power is interrupted before a P0 response is returned,
the memory contents may be lost or corrupted and the modem
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.44 Memory R
EGISTER INITIALIZATION
for
more details.)
Do not attempt to operate remotely controlled equipment outside the
communication range of the FRH-SD07TU/TB system. Doing so
could cause loss of control of the equipment.
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.
