MiiNePort E1/E2-SDK
For MiiNePort E2-SDK Evaluation Board Layout
Each module has four digital I/O (DIO) channels. (Refer to the Pin Assignment section in Chapter 1 for the
module's configurable DIO pin descriptions. Refer to the Evaluation Board Layout section in Chapter 1 to select
corresponding settings on the evaluation board.) All four DIO channels can be configured by software. A DI
channel is a channel that operates in digital input mode; a DO channel is a channel that operates in digital
output mode. You can use the evaluation board's Digital Output LEDs and Digital Input DIP switches as the
digital input and output devices, or you can connect digital input/output devices to the DIO Terminal Block.
For channels in digital output mode, the Low versus High setting is controlled from the web console. When
using a Digital Output LED as your output device, the LED will be on to indicate that the status is Low and the
LED will be off to indicate that the status is High.
ATTENTION
When using a digital input device connected to the DIO Terminal Block, the corresponding Digital Input DIP
switch must be set to OFF or High. Setting the DIP switch to ON or Low will interfere with the signal from your
digital input device.
