* The maximum sapling speed (minimum sampling interval) is different depending on the type of module.
* Sampling can be set up to the fastest speed among multiple type connected modules. If the set sampling speed exceeds the fastest speed on module, signal will be sampled and updated at the highest speed of its module and the previous data will be used until the data is updated.
* The maximum sampling speed (minimum sampling interval) varies depending on the specified recording destination. |
