Active on link mode

Under Active on link mode, a maximum of four USB devices can be used within a system. In the diagram, on the previous page, the system is already using the maximum number of USB devices (2 USB devices per Receiver). If we had two more Receiver units (making a total of four Receiver units), we could have connected a single USB device to each Receiver unit. To switch to Active on link mode, follow the instruction below.

1.Access the Web interface for the Sender unit.

2.Click the Functions tab.

3.Locate the USB over IP group and make sure the Enable USB over IP box is checked. This is the default setting.

4.Click the Active on link radio button within the USB over IP group.

5.Click the Save button within the USB over IP group.

6.The following message will be displayed, at the top of the page, indicating that the new Serial over IP options have been applied.

7.Click the Reboot button at the bottom of the page.

8.Repeat steps 2 - 6 for the Receiver unit.
