CHAPTER 6: Keyboard Commands
6.16 End Scan: [Ctrl] X
You can use this command (press and release left [Ctrl], then press and release the
letter [X] key) to stop a scan in progress. You will be connected to the computer
whose video you were viewing when the scan ended; you will have the level of
access to that computer that your user profile’s connection mode allows (see
Sections 4.6 and 5.4). Alternatively, you can end a scan by entering a Select
Computer command (see Section 6.4).
You can also use [Ctrl] X to pass a keyboard command through to an attached
ServSwitch family KVM switch. See Section 6.17.
6.17 Pass This Command Through: [Ctrl] X or [Ctrl] [Tab]
Although doing so sometimes causes port-numbering difficulties, it is possible to
connect certain other types of ServSwitch family KVM switches to the Matrix
ServSwitch’s CPU ports or user ports. Some of these other switches use a set of
keyboard commands that’s very similar to the Matrix ServSwitch’s, but the switch that’s
closer to the user will normally absorb commands sent to it without passing them
through. For example, if you select a ServSwitch™ Ultra attached to CPU port 12 on
a
Matrix ServSwitch, and you want to switch to CPU port 3 on the Ultra, you can’t just
type in left-[Ctrl] 3 [Enter], because the Matrix Switch will switch to its CPU 3 port.
This is where the Matrix ServSwitch’s pass-through command—shared by most
of the compatible ServSwitch family KVM switches—comes in. Using the same
example, you can select CPU port 3 on the ServSwitch Ultra by typing in [Ctrl] X 3
[Enter] or [Ctrl] [Tab] 3 [Enter] within the space of two seconds. Here’s how it
works: The Matrix Switch receives the [Ctrl] character and passes it through to the
attached switch, which will wait for two seconds to receive a valid command character
(and, in the meantime, passes the [Ctrl] character through to the next device in
line). The Matrix Switch then receives the X or [Tab] character, recognizes it as a
valid command character that completes a (nonfunctional) command, and
absorbs it. The Matrix Switch regards the number 3 and the [Enter] character that
follow as data characters and passes them through. The ServSwitch Ultra, however,
sees the 3 and [Enter] as completing the [Ctrl] 3 [Enter] port-selection command,
absorbs those characters, and switches to its CPU 3.
In general, the format of this command is a single left-[Ctrl] character, as many
X’s or [Tab] characters as there are layers of switches to “skip,” and the character(s)
that would normally follow [Ctrl] to form a complete command. More examples:
[Ctrl] X S causes one KVM switch attached to another to start scanning; [Ctrl] X X
stops that scan; [Ctrl] [Tab] + causes an attached KVM switch to switch to its next
CPU port; and [Ctrl] X X [F12] brings up the menu of an attached KVM switch’s
attached switch.
