◆With 920 MHz band LoRa modulation, highly reliable bi-directional communication is achieved.
◆Operation settings can be easily performed with the configuration switches.
◆Selectable from 15 wireless channels.
◆The communication mode can be selected from “Standard mode” and “Long- range mode”.
◆The transfer method of contacts can be selected from “uni-directional 16 contacts” and
“bi-directional 8 contacts”.
◆You can check the wireless communication status and terminal input/output status with the LED for
Monitoring.
◆When using the terminals in the input setting, you can switch between “Voltage contact input” and
“Non-voltage contact input”.
◆You can determine the installation location using “Communication environment checking function” that
displays the communication environment between the paired units in 5 levels.
◆When a wireless communication error occurs, you will be notified by lighting of the LED for Error Indication
and an error output.
◆The power supply is DC24V±10％.
The device can be used withAC100-240V by using the optional AC adapter.

6-1-4．Setting the periodic transmission time
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 the
communication 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”.

The communication mode can be set to “Standard mode” or “Long- range mode” with “Communication mode
configuration switch”. The communication distance and response time vary depending on the communication
mode. Set the communication mode according to the environment to be used and the signal to be controlled.
The paired devices need to be set to the same communication mode.
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.
Communication distance and response time vary depending on the usage conditions, but refer to the following
values as a guide.

6-1-7．Startup of the Communication environment checking function
“Communication environment checking function” is a function to check the status of the wireless
communication environment with the paired device. It can be used as a guide to determine the installation
location. Before using this function, the required settings between the pairs must be completed.
Turn ON the power with “Communication environment checking function start switch” turned ON, and the
communication environment checking function will start up.
The communication environment check results are indicated by three LEDs, “TX/RX”, “IN/OUT1-8”, and
“IN/OUT9–16”. This function operates until the power is turned OFF. For details of the communication checking
function, refer to “7-4．Communication environment checking function”.
■Setting method when using the Communication environment checking function
When using this function, start the device to be checked with the Communication environment checking
function turned ON, and start the paired device in normal operation. The results are displayed only on the
device side that is operating with the Communication environment checking function.
