Refreshing the Channel Status
From the OSD or LED status, you can tell which channel is connected to a
powered device and which is not. However, MCCAT does not support
real-time channel detection. Besides, the OSD remembers and shows the
last second-tier channel status instead of re-detecting the second-tier
channel status after the MCCAT switch is power cycled. Therefore, you
need to refresh the channel status shown in the OSD or LED if you have
made any changes to the hardware configuration, such as channel
swapping or disconnection and reconnection of computers. MCCAT
provides two methods to update the channel status:
 Use the F8 function key
 Use the AutoScan function
Using the F8 Function Key
1. (Optional) If the OSD is not displayed on the screen, press the hot key
twice QUICKLY (default: Scroll Lock) to activate it.
2. Press F8 to upgrade the status. The system starts to check each
channel one by one and displays “Upgrade PC Status....” on the
screen.
3. Once the status checking is complete, both of the OSD and LED
status is updated.
Using the AutoScan Function
The MCCAT switch checks all of the channels one by one and updates
both of the OSD and LED status after the AutoScan function is performed.
For instructions on activating the AutoScan funciton, see Cycling
Through Channels (on page 23).
Accessing Active Channels Only
To avoid accessing inactive channels by accident when selecting
channels, you can turn on the Autoskip function without turning on the
Autoscan function.
1. Turn on the Autoskip function by either pressing the SKIP button on
the front panel, or pressing F7 when the OSD is displayed on the
screen.
2. Select any channel, and the system automatically accesses the next
active channel if the channel you select is not an active one.
