Details of each command are shown below.
a: Application ID
All devices communicating must share the same value. It logically separates networks.
i: Logical Device ID
Set when it is necessary to identify multiple child devices.
Set any value from 1 to 100 for child devices, 121 for parent devices, and 122 for relay devices.
121 or 122 switches to parent or relay mode. In this case, Mx pin settings are not required.In the Extremely Simple! Standard App, the initial value of Logical Device ID differs depending on the operation mode.
c: Frequency Channel
All devices communicating must share the same value. It physically separates networks.
x: Transmission Output and Retry Count
Specify the radio transmission output and the number of additional packet transmissions.
t: Child Intermittent 1-second Mode Interval
Overrides the intermittent interval of the child intermittent 1-second mode from 1 second to another value. Unit is milliseconds.
Setting 0 disables periodic wakeup by timer. In this case, wakeup occurs on falling edge of DIx but not on rising edge.
y: Child Intermittent 10-second Mode Interval
Overrides the intermittent interval of the child intermittent 10-second mode from 10 seconds to another value. Unit is seconds.
Setting 0 disables periodic wakeup by timer. In this case, wakeup occurs on falling edge of DIx but not on rising edge.
f: Child Continuous 0.03-second Mode Cycle
Overrides the number of transmission requests per second from 32 times to 4/8/16 times. Retry count is not included.
z: PWMx Frequency
If one value is specified, it overrides the frequency of all PWM ports. If specified by comma separation, individual values for PWM1 to PWM4 can be overridden.
o: Option Bits
Specify a 32bit number. Enables settings linked to each bit.

b: UART Alternative Baud Rate
Overrides the alternative baud rate selected when the BPS pin is connected to GND at startup from 38400bps.
Values can be selected from 9600/19200/38400/57600/115200/230400. Specifying other values may cause errors.
This setting is not applied when the BPS pin is left open at startup. The baud rate is fixed at 115200bps.
This is a specification to prevent situations where Interactive Mode becomes unusable due to baud rate changes.
p: UART Parity
N means no parity, O means odd parity, and E means even parity.
Data bits are fixed to 8, stop bits to 1. Hardware flow control cannot be set.
Details of Option Bits
Explanation of settings linked to each bit of the Option Bits value.
00000001: Low Latency Mode
Low Latency Mode shortens the delay on the receiver side by quickly transmitting after detecting changes in DIx.
Low Latency Mode Operation
In the initial state, there is a delay of about 30-70ms until DIx is reflected on DOx. Low Latency Mode shortens this delay to about 3-10ms by simplifying processing to avoid chattering and wireless packet interference.
- Falling edge detection uses interrupts
- After detection, no new detection occurs for about 100ms
- Rising edge detection uses periodic judgment
- Transmission occurs if 5 consecutive readings are High at 1ms intervals
- (Initially, transmission occurs if 5 consecutive readings are High at 4ms intervals)
- No transmission or retransmission delay is set at detection; the wireless packet is immediately sent
- Typical delays are about 3-5ms for falling edges and about 10ms for rising edges
- Actual delay varies due to transmission/reception failures, etc.
- In intermittent mode, the time from wakeup to transmission is also shortened
00000002: Disable Periodic Transmission
Disables periodic transmission every 1 second in continuous mode for child devices.
00000004: Disable Periodic Transmission and UART Output
For child devices: disables periodic transmission every 1 second in continuous mode and stops UART output of received data.
00000010: Disable Transmission on AIx Change
For child devices: disables transmission when AIx input changes in continuous mode.
Since released AIx ports report undefined values, connect them to VCC when analog input is not used. This option allows omission of connection to VCC.
00000020: Disable AIx Value
Sends packets treating unused ports as 0xFFFF without using ADC measurement values.
00000040: Change PWMx Calculation Formula
By default, adjusted output for volume control is applied to PWMx.
This option disables that and outputs full scale for inputs below 1.8V.
Duty Cycle Calculation Formula
Duty cycle \(duty\) can be expressed using input voltage \(V_{input}\) and power supply voltage \(V_{cc}\) as in (1).
When this option is enabled, (2) is applied instead.
Note that inputs above 2.0V are treated as unused.
00000100: Transmit Only When Button Pressed
Continuously transmits packets when DIx input is Low.
For example, used to remotely control a motor. The motor runs while the remote button is pressed and stops when the radio signal is lost.
Continuous Transmission Operation
- When any
DIxis Low, transmits 32 times per second - Continues transmitting 32 times per second for 1 second after all
DIxtransitions to High - If no packet is received for 0.5 seconds after any
DOxtransitions to Low, allDOxreturn to High.PWMxis retained.
00000800: Disable Internal Pull-up of DIx
Disables all internal pull-ups (about 50kΩ) of DIx.
00008000: Add Relay Function to Child
Adds relay function to child devices in continuous mode. Maximum relay steps is 1.
00001000: Set Max Relay Steps to 2 for Child Relay
Changes maximum relay steps to 2 when 00008000: Add Relay Function to Child is set.
00002000: Set Max Relay Steps to 3 for Child Relay
Changes maximum relay steps to 3 when 00008000: Add Relay Function to Child is set.
00010000: Invert PWMx Waveform
Inverts the output waveform of PWMx.
When maximum value is input to AIx, PWMx becomes Low.
00020000: Turn Off PWMx After Startup
Sets PWMx output to Low state after startup or reset.
PWMx is High during about 1ms hardware initialization period after startup.00080000: Alternative Port Assignment
Enables alternative port assignment.
Connecting transistors etc. to PWM2/PWM3 may cause unstable operation (Details). Use this option in such cases.

00100000: Turn Off DOx for 2 Seconds After Startup
Sets DOx to Low state for 2 seconds after startup or reset.
You can light LEDs connected to DOx at startup.
DOx is High during about 1ms hardware initialization period after startup.00400000: Invert DOx Output
Inverts DOx output.
Unlike the initial state, when one DI is Low level, the other DO is High level.
00800000: Disable Internal Pull-up of DOx
Disables all internal pull-ups (about 50kΩ) of DOx.
