When this condition occurs, follow the steps below:
1) The current presenter should click “Establish a Session” to try to resume
the presentation. If the presentation is successfully resumed, the
abnormal condition is just temporary and no further action is required.
Troubleshooting
(Continued)
The DPG-2000W Session is Interrupted During a Pre-
sentation
This signals that the
DPG-2000W
has detected a link-loss for an extended
period of time or a severe communication error. Since the
DPG-2000W
is
designed to support one presentation at a time, the
DPG-2000W
cleans up
the communication error and returns itself to the initial state (where it displays
the banner page) of being “available for connection” in order to prevent the
DPG-2000W
from being locked up due to a malfunctioning user computer.
With the auto-reconnection feature, this rarely occurs.
The Presentation Screen Appears Frozen During a
Presentation
This indicates that the
DPG-2000W
has detected a link-loss. The
DPG-2000W
and DPG-2000W PSM have an intelligent built-in mechanism to detect the
link-loss and can automatically restore the connection. When a link-loss has
been detected, DPG-2000W PSM will display a message box and attempt to
automatically restore the connection. If the auto-reconnection attempt is
successful, the user does not need to do anything. In this case, the
auto-reconnection is transparent to the user. However, if the cause of the
link-loss is due to a physical disconnection, for instance, the wireless card was
pulled out, the user needs to restore the physical connection so that the
auto-reconnection attempt can proceed. The presentation screen will not be
updated once the link is lost, unless a reconnection is re-established. However,
if link-loss occurs for an extended period, the
DPG-2000W
will terminate the
reconnection waiting state and display the banner page indicating that a fresh
presentation session is ready to be established.
The default duration for a link-loss is 8 seconds. The
DPG-2000W
will retry 3
periods of this duration. If no re-connection is established before the reconnection
time runs out, the
DPG-2000W
returns itself to the banner page.
