ADP130 USB to Isolated DIO Module

An optional DIO add-in card is available. The add-in card has an NXP i.MX1050-series microcontroller that can communicate with the host processor over USB. The card provides an interactive shell for configuration on a virtual COM port.

Supported VIN/Input/Output Voltage: 5-48V

Configuring the DIO Card

The add-in card is configured interactively through its shell using a serial terminal emulator program. The shell is accessed differently depending on operating system.

To access the shell on Windows:
  1. Open Device Manager by pressing Win+X M. Open the “Ports (COM & LPT)” menu.
  2. Note the “COM#” numbers on each port listed.
  3. Download and install PuTTY from the link above.
  4. Open PuTTY. When prompted, enter the COM port number in the “Serial line” text box, then click “Open”.
  5. If the port number was correct, a “uart:~$” prompt should appear. If not, try a different port.
To access the shell on Linux:
  1. Install picocom, e.g. “sudo apt install picocom” on Ubuntu.
  2. Open the shell’s virtual COM port with picocom by running “picocom /dev/serial/by-id/usb-OnLogic_DIO-*-if00”.
  3. Some Linux distributions may not configure udev to produce by-id links. If those links are missing, try /dev/ttyACM0 and similar devices.

Once the shell is open, type “help” for usage information. A description of available shell commands can also be found here.
