Now that you have already connect to the I/O controller, you can send commands via TCP/IP connection to control output and read input. The default device address is at, port 10001.

The following are some program which you can test and send the commands,


Programs for Testing I/O Controller

  • IOaT-E4 software application
  • WinOS Hyperterminal program
  • Docklight communication test software
  • WinOS Telnet terminal


Commands to Toggle Output IO3
