Connecting To A Serial Device; Digital I/O Channel Settings; Schematic Design Guide - Moxa Technologies MiiNePort E1 Series User Manual

Connecting to a Serial Device

To connect to a serial device for testing and development purposes, the module should be installed on the
evaluation board. Make sure the serial interface is configured correctly before connecting the evaluation
board to the serial device. (Refer to Selecting the Serial Interface section above when you are using
jumper blocks to select the serial interface on the evaluation board.) The module's serial signals are routed
to and from the RS-232 or RS-485 COM port on the evaluation board. Use a serial data cable to connect the
serial device to the COM port on the evaluation board.

Digital I/O Channel Settings

Each module has 3 digital I/O (DIO) channels. (Refer to the Pin Assignments section above for the
module's configurable DIO pin description. Refer to MiiNePort E1-ST Evaluation Board Panel Layout to
select the corresponding setting on the evaluation board.) Software can configure all 3 DIO channels. A DI
channel is a channel that is operating in digital input mode; a DO channel is a channel that is operating in
digital output mode. You may use the evaluation board's Digital Output LEDs and Digital Input DIP switches
as the digital input and output devices, or you may connect digital input/output devices to the DI/O
Terminal Block.
ATTENTION
When using a digital input device connected to the DI/O 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.
For channels in digital output mode, Low and High status is controlled from within the web console. When
using a Digital Output LED as your output device, Low status is indicated by the LED lighting up, and High
status is indicated by the LED turning off.
