Port ID Numbering

ID Numbering Overview

Each CPU Port on a Master View installation is assigned a unique Port ID. You
can directly access any computer on any level of the installation by specifying
the Port ID of the CPU Port that the computer is connected to - either with the
Hotkey port selection method, or from the OSD.
The Port ID is a one, two, or three digit number that is determined by the Stage
Level and CPU Port number of the Master View unit that the computer is
connected to. 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 unit;
the third digit represents the CPU Port number of the Third Stage unit.
For example, a computer attached to a First Stage unit has a one digit Port ID
(from 1 to 8), that corresponds to the CPU Port number that the computer is
connected to.
A computer attached to a Second Stage unit has a two digit Port ID. The first
digit represents the CPU Port number on the First Stage unit that the Second
Stage unit links back to; the second digit represents the CPU Port number on
the Second Stage unit that the computer is connected to. Therefore, a Port ID of
23 would refer to a computer that is connected to CPU Port 3 of the Second
Stage unit that links back to CPU Port 2 of the First Stage unit.
Likewise, a computer attached to a Third Stage unit has a three digit Port ID.
One with a Port ID of 241 would be connected to CPU Port 1 of a Third
Stage unit, that links back to CPU Port 4 of a Second Stage unit, which, in
turn, links back to CPU Port 2 of the First Stage unit.
