zThis is a Class A instrument. In a domestic environment this instrument may cause radio
interference, in which case the user is required to take adequate measures.
zThis instrument is protected from electric shock by reinforced insulation.
So please arrange reinforced insulation to the wire for input signal against the wires for
instrument power supply, source of power and loads as far as possible.
zThis instrument is manufactured on the assumption that it is used in the condition of being
mounted on the instrumentation panel. Therefore, take the necessary measures on the
equipment side mounted with this instrument so that the operator or other personnel are
not accessible to high-voltage blocks in this instrument such as power supply terminals,
etc.
zAlways observe precautions described in this manual. Otherwise serious injury or accident
may result.
zConduct all of the wiring in accordance with the local codes and regulations.
zInstall a protection device such as a fuse, etc. in the power supply, input or output line, if
necessary.
zDo not allow metal fragments or lead wire scraps to fall inside this instrument. This may
cause electric shock, fire or malfunction.
zFirmly tighten each terminal screw at the specified torque. Otherwise electric shock or fire
may result.
zDo not place any obstacle around this instrument in order not to impede radiation of heat.
And do not close ventilation holes.
zDo not connect wires to unused terminals.
zBefore cleaning the instrument, always turn off the power supply.
zRemove stains from this instrument using a soft, dry cloth. Do not use a volatile solvent
such as thinner in order to avoid deformation or discoloration.
zDo not rub nor strike the display unit of this instrument with a hard object.
NOTICE
zThis manual is prepared especially for readers who already have a fundamental knowledge of
electricity, control, computer and communication.
zThis manual is subject to change without prior notice.
zExamples of figures, diagrams and numeric values used in this manual are for a better

3. SETTING FOR COMMUNICATION
In order to make communication between the REX-F9000 and the host computer (or PLC), it is
necessary to set the device address, communication speed, communication data configuration, interval
time and protocol. Communication settings are made in parameter group 24 (PG24).
3.1 Preparation for setting communication parameters
The setting of parameter group 24 (PG24) can be changed only in control stop mode. Before the
SETUP mode is selected, it is necessary to set the mode selection of "Control RUN/STOP" to
"STOP."
cPress the MODE key to set the instrument to the mode transfer.
dPress the MODE key to display "Control RUN/STOP."
ePress the DOWN key to control is changed from execution
(RUN) to STOP.
