POINTS OF CAUTION
■ POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 240V AC rating: 85 – 264V, 47 – 66 Hz,
approx. 15VA at 100V AC
approx. 20VA at 200V AC
approx. 21.5VA at 240V AC
24V DC rating: 24V ±10%, approx. 8.5W
vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -10 to +55°C
(14 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
• Attachment and adjustment of sleeve antenna: Loosen
the connector (See the below figure), and rotate the antenna. Holding the antenna vertically, tighten the connector by hand. Make sure to fix the antenna firmly.
• Attachment of rooftop antenna: The magnet on the bottom
face allows the antenna to be attached on a metal box and
such. To obtain optimum performance from the antenna,
attach it on a metal plate (recommended dimension: 500
mm × 500 mm or more). However, in the case of connecting FE1 or FG of the power supply module to a metal
plate, the isolation between FE1 or FG and the internal
bus or internal power or antenna connector will be lost.
Tighten the connector with a specified torque (0.9 N∙m).
As a guide, finger-tighten the connector until it stops, and
then rotate it 10 to 15 degrees with a wrench. Do not force
the cable to bend beyond the acceptable bending radius
of 3 cm.
• Please note that using 7.5 m coaxial cable (model: CXSAC0SAD0Q0750) (OKI) for extension decreases transmission distance.

■ HOT-SWAPPABLE MODULES
• The module can be replaced while the power is ON. Be
sure to replace it when the module is not communicating with a host, as it may affect the system. Replacing
multiple modules at once may greatly change line voltage
levels. We highly recommend to replace them one by one.
■ ENVIRONMENT
• Indoor use.
• Attach the antenna to the unit.
• When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
• Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
■ AND ....
• The unit is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

CAUTION REGARDING RADIO FREQUENCY
■ FCC NOTICE
• This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation.
■ FCC CAUTION
• Changes or modifications not expressly approved by the
party responsible for compliance could void the user’s authority to operate the equipment.
■ NOTE
• This equipment has been tested and found to comply with
the limits for a Class A digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when
the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
• This transmitter must not be co-located or operated in
conjunction with any other antenna or transmitter.
INSTALLATION
Use the Installation Base Model R3-BS, or Model R3-BSW
for free I/O address capability.
Before mounting the Network Interface Module onto the
Base, please do the following.
■ DATA ALLOCATION
Set the DIP switches (SW1, SW2) so as to assign the data
area size to each I/O module mounted on the base.
The data sent/received via Modbus is mapped according to
the setting.
See “COMPONENT IDENTIFICATION” and “MODBUS
I/O ASSIGNMENTS.”
■ MOUNTING TO THE BASE
I/O 1I/O 2I/O n
■ FCC RF EXPOSURE INFORMATION
• This equipment complies with FCC radiation exposure
limits set forth for an uncontrolled environment and
meets the FCC radio frequency (RF) Exposure Guidelines. This equipment should be installed and operated
keeping the radiator at least 20 cm or more away from
person’s body.
FCC ID: 2AOTF-0000008 (with no power supply)
FCC ID: 2AOTF-0000009 (24 V DC)
FCC ID: 2AOTF-0000010 (100 – 240 V AC)
Contains FCC ID: 2AKGW-1TD3016A1
With Model R3-BS base, mount the I/O Modules from the
left end (I/O 1) to the right in order that the Network Module assigns data areas from I/O 1.
Network Module(s) and Power Module are mounted basically at the right end though technically they could be
mounted in any position.
With Model R3-BSW base, there is no limitation in mounting positions as I/O address can be assigned freely to each
module using rotary switches equipped on the base.
must be assigned to each I/O module
slot position to specify how many data areas (four types) are
to be occupied by each module.
Two bits from SW1 and SW2 are assigned to each position,
so as to specify data areas for each of the slots No. 1 to 8.
Setting for No. 9 and later slots is identical to No. 8.
*2. Refer to the specifications of the related series for the Data
Allocation Type of I/O modules.
• Dual Communication: SW3-1
When two network modules are mounted, one must be
‘Main’ (OFF) network and the other must be ‘Sub’ (ON) network. For single communication, the network module must
always be set to ‘Main’ (OFF).

• Input Error Data: SW3-2
Hold: When the communication from an input module is lost
due to the input module error, the network module holds the
signal and stands by until the communication recovers.
Set to ‘0’: When the communication from an input module
is lost due to the input module error, the network module
outputs ‘0.’

• Main/Sub Switching Control: SW3-3
The host PC or PLC can choose whether ‘Main’ or ‘Sub’ bus
is used when the switching control is set to ‘Host.’
In ‘Normal’ mode, ‘Main’ bus is normally used, while ‘Sub’
bus is when the main communication has failed.
