International Sun Keyboards
The UNIMUX can recognize international layouts for Sun keyboards. In order to use an international Sun keyboard, follow this
procedure:
1. Power-OFF the CPU from the UNIMUX
2. Connect the international keyboard to be used to the UNIMUX
3. Power-ON the CPU to the UNIMUX
It is also possible to configure the UNIMUX to emulate a specific international Sun keyboard regardless of what actual keyboard is
connected. This is recommended when the CPU needs the layout code (i.e. a SUN CPU) and the keyboard doesn't have an
explicit layout code (i.e. some Windows keyboards). To do this, manually set the UNIMUX to indicate the international keyboard
identification number to the CPU by following the instruction on page 16 for Language Selection.
DDC SUPPORT
(Optional)
DDC information allows the CPU to automatically select the optimal resolution for the monitor by receiving, at power up,
information from the monitor concerning its resolution specifications.
When DDC Support is installed, the DDC information is acquired from the monitor by the UNIMUX switch when the UNIMUX is
powered-up. The DDC information will be made available at every CPU port.
Note: In order for the CPU to correctly receive the DDC information from the switch at boot-up, the switch
must be powered up before all attached CPUs.
TROUBLESHOOTING
PROBLEM:
Keyboard Errors
SOLUTION:
Check cable connections on each CPU and the switch.
PROBLEM:
No Video
SOLUTION:
Check cable connections on each CPU and the switch. Verify that keyboard and video connect from each CPU
to matching ports. After reconnecting, CPU may need to be re-booted in order to sense the monitor connection.
