26 CATx KVM Extender Range
Command Mode
During normal use, the remote console keyboard functions in the usual manner.
However, by using a specific ‘hot’ key sequence, you can set the keyboard into
a Command Mode. From this, you can use various keys and key combinations
to tune the video signal and generally configure the extender system.
To enter Command Mode:
1. Ensure that you have installed and powered up the system according to the
instructions in the Section 2.
2. Press the following key combination on the remote keyboard:
<Left Control> + <Left Shift> + <F10>
3. From Command Mode, you can use one or more of the ‘hot’ key sequences
shown on page 6 to configure the system. The next section gives a full
description of the video optimization procedure.
To exit Command Mode:
Press <Esc> to exit Command Mode and save the settings. Alternatively, press
<Left Control> + <Esc> to exit command mode without saving changes made
in the current session.
The Remote Unit automatically times out Command Mode after 30 sec of inactivity,
saves all settings to EEPROM and returns normal function to the keyboard.
Status LEDs in Command Mode
In Command Mode, the Remote Unit:
• Illuminates the yellow channel 1 LED continuously (see Figure 9). Note.
The Yellow LEDs on other video channels are not lit.
• Flashes the status LEDs (Num Lock, Caps Lock, Scroll Lock) on the
connected keyboard to indicate video channel selection (to which
adjustments will be applied).
The number of flashes indicates the selected video channel:
Keyboard LED flashes Video channel
1 Channel 1 (default)
2 Channel 2 (Dual and Quad systems only)
3 Channel 3 (Quad systems only)
4 Channel 4 (Quad systems only)
Slow Flashes All channels simultaneously (Channel 0)
