Get Round Trip Time
This function measures the round trip time between the source device and the remote device.
"Round trip time" is the time taken to make a communication between two devices.
Only one remote device can be measured at a time.
The procedure to measure the REC round trip time is as follows:
Procedure
1
Save the REC path information file.
The default file name is "rec_path.bin".
If the [Cancel] button in the [File Download] dialog box is clicked to
cancel the operation, an error may occur in the web browser.
To cancel the operation after the [File Download] dialog box is
displayed, wait at least 10 minutes before clicking the [Cancel] button
or click the [Save] button to complete the operation and delete the
unnecessary file.
Click the [Close] button to return to the [Copy Path] screen.
•
Round trip time can be measured only when the connection type is
"Remote". Round trip time cannot be measured when the connection
type is "Direct".
•
Set the REC session status to "Suspend" between devices before
measuring.
•
Make sure that the physical path is correctly configured between
devices before measuring. When a copy path has an error, the round
trip time cannot be measured correctly.
•
If the path between devices is changed, measure the round trip time
again.
•
Round trip time measurement requires a maximum of 160 seconds.
Select the remote device to measure the REC round trip time, and click [Get
Round Trip Time] in [Action].
A remote device with "Direct" as the connection type cannot be
selected.
