    1.1 iVu Plus Communications The iVu Plus provides for communicating with other devices via Ethernet or a UART serial communications port (RS-232). In order to establish an Ethernet connection to the sensor, the external device must be configured with the correct IP address and correct TCP port to communicate.

    1.1.4 Image Export Sample Application The iVu Plus BCR installation CD has a Image Export sample application that provides a way to save exported images. In a production environment, you will need to write your own application to process exported images, for example to display them on an HMI or to save them to disk.

    2 Testing and Troubleshooting iVu Plus Communications 2.1 Understanding the Communication Log The iVu Plus sensor includes the following Communication Logs: • Command Channel Log that can be used to ensure that commands are properly formed (syntax is correct), and provides a history of commands issued along with responses to these commands.

This can be useful for debugging issues such as improper wiring, mismatched baud rates, or other serial I/O issues.

On the requesting device, transmit one or more bytes to the iVu sensor. • If the data byte values appear correct and the number sent by the requesting device matches the number received by the iVu sensor, then the transmit/receive functionality is working properly.
  • Page 20 Plus BCR Communications User's Guide 3. If the byte count does not match, re-verify that the settings on both devices match exactly. If no bytes are received, re-check the wiring. If the correct response frame is received, then basic electrical and port settings are correct.

    Plus BCR Communications User's Guide 3.2 Conventions Used for Examples There are a number of command channel examples included here, and the following are the conventions used in the examples: • All examples use <CR><LF> for the end-of-frame delimiter, and this delimiter is always denoted in hex (\x0D\x0A) since that is what is displayed in the iVu logs and, for example, the Port Status screen.
