4.3.3.2 Response for I/O State Request Command
- Identical with ON/OFF control response.
- Sent even if the state of input port or ADC (in Switch Input mode) has been changed
(based on a threshold voltage). A change of input state is recognized when the input
value changed is maintained for 15 ms.
- In case of state response, the control state field returns 0x30 in Run mode and 0x31 in
Setting mode.

- The Rhio232 returns a state response once after set command is received. It does not
return any state response until it receives run command even if it is switched to Setting
mode.
- When setting output port, ADC input port, Port Enable, Port Power-out Recovery or
serial number, send set command first to switch it to Setting mode. (Check command is
working in both Setting and Run mode.)
- Once each setting is completed, send run command to switch it to Run mode.
