The BASIS 722az includes an RJ-45 network connection port on the rear panel, which is labeled "QSControl". All data communications between the BASIS 722az and a control computer, such as a PC running the QSControl.net server or client application, takes place via this rear panel QSControl port. - Page 5 Example 1- QSControl.net X-over mode: This example illustrates the simplest connection you can make between the BASIS 722az and a computer. You simply use a CAT-5 crossover cable connected between the BASIS 722az rear panel QSControl port and a computer's network interface card, (NIC). Note that the computer’s NIC must support 10BASE-T Ethernet (nearly all do).
- Page 6 QSControl traffic and one for all non-QSControl traffic. The partitioning provides a dedicated virtual local area network (VLAN) for the BASIS 722az and all other QSControl devices, including a management PC running the QSControl.net server or client application. As with example #2, as many BASIS devices may be connected to the network as there are switch ports available. All BASIS units will be able to communicate with the computer.

If the BASIS 722az operates in an unexpected way or is not responding to any communications after a new firmware file is uploaded to it, it is likely the file was corrupted during transfer. If this occurs, there is a “backup” program in the BASIS 722az that will enable you to communicate with it. - Page 16 6) The Hyper Terminal main window will appear next, but blank.
