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. To access the Command Channel Log, go to Main Menu > Logs >
Communication Logs > Command Channel .
• Data Export and Image Output logs that are purely output logs (that is, there is no receive activity to log).
Some notes about the logs:
• To see an expanded view of each entry, click on the small right-triangle control on each entry.
• To save the log, click the save icon. The saved communication log can be loaded into the emulator for troubleshooting offline.
The table below describes the icons used in the Communication Log, the up-arrow indicates an incoming request to the iVu from the
control device; the down-arrow indicates an outgoing response from the iVu to the control device.
Icon
Description
Port opened.
Port closed.
Indicates that the command has been processed without errors.
Indicates that the incoming entry is stalled (no new bytes), or end-of-frame delimiter was not re-
ceived, or client is not reading data on ethernet.
If the response frame contains an error or is dropped, the log entry icons for the request and the
response frames will be colored red, and the displayed error count will increment by one.
If the command takes a long time to process, the last long entry will change to an hourglass (for
example, during trigger of long inspections).
For Ethernet channels:
• The channel's log will show an Enabled entry that indicates which port is being listened to.
• When a client connects, a log entry is added that indicates which IP address connected.
• When a client closes the connection, a log entry indicates that the channel is no longer being listened to.
2.2 Ethernet I/O
2.2.1 Ethernet I/O Status
The Ethernet I/O Status screen can be used to verify that the Ethernet wiring has been correctly set up. In addition to determining if the
link has been established, incoming and outgoing traffic can be monitored.
