34 UltraLink 2 DVI Installation and Operation Manual
The Power control functionality is a subset of the Hosts functionality. For it to work, several conditions need to
be met, as follows.
 The UL2-DVI must be connected to a serially controlled Remote Power Switch, as described in
Installation section.
 The UL2-DVI Serial Port must be configured to work with the Remote Power Switch, as described in
the Configuration section.
 The connected host computer(s) must be identified to the UL2-DVI through the Hosts Configuration
screen, as described in the Configuration section.
 The Power Control Sequences for the host computer(s) must be defined in the Host Configuration
screen, as described in the Configuration section.
 The logged-in user must have rights to access the Power Switching option, which are set up in User
Accounts Configuration, as described in the Configuration section.
Access Mode Control
Access Mode specifies whether multiple users can access a host computer simultaneously, or whether only a
single user may claim access at a time. The two modes are Shared (the default) and Private. Shared mode
allows as many as 4 users to log in to a host computer simultaneously, each with use of keyboard and mouse.
Private Access Mode permits one user at a time to access a host computer. If multiple users are logged in
with Access Mode Shared, and one of the users changes Access Mode to Private, the other users are
disconnected with a message displayed that a user has changed Access Mode to Private. Attempts to connect
to the computer will fail until the user in Private mode switches Access Mode to Shared, or logs out. The only
exception is the Administrator user, who can log in even when another user is in Private Mode. The
Administrator can also change the Access Mode from Private to Shared.
