Raritan Engineering Water System MCCAT18 用户手册

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 unit 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 onscreen, 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 unit 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 19).

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 onscreen.

2. Select any channel, and the system automatically accesses the next

active channel if the channel you select is not an active one.
