Port ID Numbering
Each CPU Port on an installation is assigned a unique Port ID. You can directly access any computer
on any level of the installation by specifying the Port ID using the Hot Key port selection method, or
from the OSD Main Menu.
The Port ID is a one, two or three digit number. It is determined by the path taken from the first stage
through any additional stages in order to reach that CPU. The first digit represents the CPU Port
number of the First Stage unit; the second digit represents the CPU Port number of the Second Stage;
the third digit represents the CPU Port number of the Third Stage.
1. A CPU connected to a First Stage unit:
The Port ID is a single digit corresponding to the port where the CPU is connected.
2. A CPU connected to a Second Stage unit:
The Port ID has two digits. The first digit corresponds to the port where the Second Stage unit is
connected. The second digit is the Port ID on the Second Stage unit where the CPU is connected.
For example, a Port ID of 23 refers to a CPU that is connected to Port 3 of a Second Stage unit that,
in turn, is cascaded down from Port 2 of the First Stage unit.
3. A CPU connected to a Third Stage unit:
A computer attached to a Third Stage unit has a three digit port ID. The first digit corresponds to the
port on the First Stage, the second digit to the port on the Second Stage and the third digit to the
port on the Third Stage. For example, a Port ID of 241 refers to a CPU that is connected to Port 1 of
a Third Stage unit, that is cascaded down from Port 4 of a Second Stage unit, which, in turn, is
cascaded down from Port 2 of the First Stage unit.
Hot Key Operation
Hot Key Navigation
Hot Key navigation allows you to access connected PCs directly from the keyboard.
To select a port with the Hot Key method, press the Left [Ctrl]+[Alt]+[Shift] or Right
[Ctrl]+[Alt]+[Shift] keys sequentially and enter the CPU’s unique Port ID number (see previous
section).
Hot Key Navigation can be used when in OSD Mode (see next section)
OSD Operation
Hot Key Operation under OSD
Hotkey navigation can be used under OSD mode. To hotkey select a port from the OSD, do the
following:
1. Press either Left [Ctrl] or Right [Ctrl] twice to access the OSD Main Menu.
Note: 1. In OSD, when you are at the Main Menu you can key in the Port ID for the computer you wish to access
without first having to press the [Ctrl+Ctrl] combination.
2. You can optionally change the hotkey to the Scroll Lock key (see F6, below), in which case you would
press [Scroll Lock] [Scroll Lock].
2. From the OSD Main Menu, key in the Port ID for the computer you wish to access (see Port ID
Numbering, above, for details), then press [Enter].
The console now controls the PC that you have selected, and the OSD automatically closes.
When you key in the Port ID, note the following:
• You must key in the Port ID and press [Enter] within 1 second for each keypress after pressing
the Left [Ctrl]+[Alt]+[Shift] or Right [Ctrl]+[Alt]+[Shift] keys sequentially.
• Number keys must be pressed from the regular keyboard; not from the numeric keypad.
• The keys must be pressed and released one key at a time.
• If you submit an incorrect Port ID, an error message displays, and you are returned to the OSD
Main Menu.
