Question:  I have multiple Tempest 2400 and Tempest 900 base stations connected to a local area network (LAN).  Is it possible to have multiple PCs with TDesk active or multiple instances of TDesk software open on a single computer?
Answer: 
If T-Desk is closed on one computer and opened on another computer, the new instance of T-Desk should connect to all BaseStations.  Running multiple instances of T-Desk, either on the same computer or on multiple computers on the same local area network, is not supported.
If BaseStations are logged onto T-Desk and a second instance of T-Desk is opened, the second instance will not be recognized by the BaseStation(s) and the BaseStation(s) will remain logged onto the first instance. This prevents anyone but the appropriate administrator from accessing the BaseStation(s).
