DIAGNOSTIC INFORMATION
At power up, the VOPEX uses the mode LEDs on the front panel to report some status. The sequence of events is as follows:
1. When unit is first powered, the LED state is indeterminate.
2. All LEDs are turned OFF, then flashed ON and OFF to indicate processor activity.
3. One LED for each keyboard detected is flashed ON and OFF.
4. One LED for each mouse detected is flashed ON and OFF.
5. The LEDs are left in the proper mode status (see “MODES OF OPERATION ”).
MODES OF OPERATION
This VOPEX has three basic modes of operation: INSTANT AUTO. DELAYED AUTO, and USERx. Press the “MODE” button on
the front panel of the VOPEX to select the desired mode per the chart below:
INSTANT AUTO: Any user can gain immediate access to the CPU by pressing a key or moving a mouse, unless another user is
active.
DELAYED AUTO: Any user can gain access as long as no user LEDs are currently illuminated. When the active user’s
keyboard/mouse are idle for at least 5 seconds, user LED goes out and anyone can then gain access.
USERx: The VOPEX has a user mode for each port. When any user mode is selected, that LED remains ON and all other users
are locked out until the mode is changed by pressing the MODE button.
Monitor
All monitors connected to the VOPEX display exactly the same information. For example, if the user connected to Port 3 is
inputting data, then all users connected to the VOPEX see what that user is entering.
