In this appendix, we provide information on sending commands to the module's DIO channels over an Ethernet
network. Digital I/O commands and responses are accessed using a specific TCP port (default 5001) on the
module. Each command is initiated by the host and is followed by a response from the module. A utility on the
CD-ROM can be used to test the DIO access commands.
