The wireless communication of the device is an event type that communicates when the input state into the
input terminals is changed.
If there is no change in the input state, communication is not performed. A function to periodically check thecommunication between the paired devices is a periodic transmission. The intervals of periodic transmission
can be set with “Periodic transmission time configuration switch”. If there is no change in the input state into the
input terminals for the set time, periodic transmission is performed. To detect communication errors quickly,
select “10 seconds”.

・Near a television or radio.
・Near objects that generate strong noise, such as motors and inverters.
・Locations where strong magnetic field is generated.
・Locations surrounded by steel frames or metal walls.
・Near the wireless devices that use the same frequency as the wireless frequency used by the unit.
・Near the devices that can malfunction due to radio waves from the unit.
②Install the unit as high as possible.
③Install the antenna as vertically as possible and avoid it from being parallel with a metal plate or wire. Also,
keep it away from a metal plate or wire as much as possible.
④Install as far away from noise sources as possible.
⑤Communication performance varies greatly depending on the installation environment. Please confirm that
communication is possible before installation.
⑥It is not dust/splash proof. Depending on the installation environment, take measures, such as integrating it
into the case.

For the setting method of the I/O terminals, refer to “6-1-3. I/O terminal settings”.
■Setting the input terminals
When setting the input terminals, the input specification(voltage/non-voltage) can be switched.
It can be switched by short circuiting/ not short circuiting “A-B” terminals of each I/O terminal.
When short circuited, the input specification becomes Non-voltage contact input”, and when opened, it
becomes “Voltage contact input”.
*At the time of shipment, as the terminals are short-circuited by insertion bridge, the input
specification is non-voltage contact input.

Use of voltage/current exceeding the rated values may damage the unit as well as otherconnected units. Connect an appropriate drive circuit, such as a relay, depending on the units ordevices to be connected. Especially, when controlling inductive loads, such as lamps and relay,
take appropriate measures on the load side. The right figure shows a connection example forcontrolling the relay. A diode is connected to the device to protect it from surge voltage thatgenerates in the relay coil.

7-3-4．Connection cable
For the cable to be connected to the terminal block, follow the specifications below.
・Wire connection range
0.14mm2～1.5mm2(Common to solid/ stranded wire)
AWG26～AWG16・Strip-off length
6.0mm(Preliminary soldering at the tip of wire is not allowed)
The tightening torque of the terminal block screw is 0.5Nm-0.6Nm. Tighten the screw with a flat-blade
screwdriver.
When checking continuity with the head of the terminal block screw, check it with the screw tightened.

The case of the unit is electrically connected to the GND（COM）of the internal circuit.
When connecting the cable, be careful to prevent the conductor part from contacting the case.

Use ferrule terminals (rod shaped terminal) to prevent the wire from fraying.

7-4．Communication environment checking function
When determining the installation locations, use the “Communication environment checking function” forchecking the status of wireless communication environment with the paired device.
Before using the function, you need to perform “Channel setting”, “SET number setting” and “Communication
mode setting”. For the setting method, refer to “6-1. Configuration switch”.
Place each device to be paired in your desired location temporarily, and start the device to be checked with theCommunication environment checking function, and start the other device in normal operation. For thestarting method of the function, refer to “6-1-7 Startup of the Communication environment checking function”.
The communication environment check results are displayed in

5 color-coded steps by 3 LEDs of “TX/RX”,“IN/OUT1–8”, and “IN/OUT9–16”.

For about 10 seconds after startup, an orange-color scroll display is performed.
O

After about 10 seconds, the communication environment check results are displayed. The result display is
updated. The result is displayed from the communication content of the last about 30 seconds. Check the result
after about 30 seconds at each location where the communication environment is checked.
To perform stable communication, it is recommended to install the device where the check result is “excellent”
or “good”. Perform communication environment check in the environment and condition as close to the actual
operation as possible.

8．Communication
8-1．Communication type
Wireless communication of the device is an event type that communicates when the status of the input signal
into the input terminal changes. Normally, no radio wave is emitted, which reduces interference in wirelesscommunication. Also, wireless communication is bi-directional regardless of its usage. After transmitting thecontact data, it checks a response from the paired unit. When a response from the paired unit cannot bereceived, the device performs retry communication to securely transfer the contact data.
In addition, secure communication between paired units is achieved by confirming that the channel and set
number match. Set the communication channel and set No. with “Channel configuration switch” and “Set No.
configuration switch”. For the setting method, refer to “6-1-1. Communication channel settings” and “6-1-2 Set
number settings”.

8-2．communication error output
If there is no response from the paired unit during communication or periodic transmission due to a change in
the input signal, the device performs retry communication. However, if no response is received even after
certain times of retry communication, a communication error output is performed.
The communication error output is performed by lighting of the LED for Communication Error Indication andproducing an external output from the error output terminal block.
The communication error output will be reset when communication is normally established.
For error output terminal block, refer to “7-3-2. Error output terminal block”.

9．Notes for use

Response time refers to the time it takes when a signal is inputted into the input terminal until a signal is
outputted from the output terminal of the paired unit.

Response time

Response time varies depending on the settings of the communication mode and input judgment time.
The time shown below is response time when the input judgment time is set to “10msec”, and wirelesscommunication can be established without retry communication.
When the input judgment time is set to “100msec”, the response time will be +90msec.

9-2．Selecting communication channel
When using multiple pairs in the same area, set each pair to a different communication channel.
Since the wireless communication of the device is an event type, 15 channels can be used in the same area.
【Example：Using 4 pairs in the same area】
The channels should be spaced as far apart as possible. Preventing the spacing between the channels frombeing equal can reduce impact on communication of other pairs when communicating at the same time.
