Read cycle: The cycle at which data is read from other devices. Select the read cycle
from [125 ms], [250 ms], [500 ms], [1 s], [5 s], [2 s], or [10 s]
Timeout: Specify a time period that the DXP waits for a response from the specified
slave device after transmitting a command. Select the timeout time from [125 ms], [250
ms], [500 ms], [1 s], [5 s], [2 s], [10 s], or [1 min].
Retrials: The number of times to retransmit the command when there is no response
from the specified slave device. Select the number of retrials from [Off] (0), [1], [2], [3],
