sources on device 1 are shown (which in the ex-
ample are the 32 inputs on the I/O card in slot 1
of a VistaMax frame, set as device 1).
Include_2=D2, sets which sources are shown
on device 2, which in this case is the BMXdigital
console. 241-256 are the analog and digital in-
puts on the Net Card.
Signal ID Numbers
Each signal in a VistaMax system can be
uniquely identified by using either a Global ID
number—a five to seven digit number that
uniquely identifies every possible signal in a Vis-
taMax system; or by using a universal number,
which consists of a device number shortcut (D plus
the community member’s device number) followed
by a local number.
Universal numbering was shown in the previ-
ous example where D1,65-96 uniquely identi-
fied signals 65 to 96 on device 1.
When referring to signals within one console or
a rack, a local number can be used. But local num-
bers are repeated on all devices of the same type,
for example, all consoles use local number 225
for the PGM 1 bus signal. Needless to say, this
means that a local number is only usable on a
local console or rack to refer to signals on that
console or rack.
To turn the local number into a unique univer-
sal number simply add the device number (e.g.,
D1, D2, and so on, up to D63) before the local
number to refer to a specific signal on a specific
console or rack in the system.
The operating system does the same thing but
it uses global ID numbers, which are not very in-
tuitive for end users to easily use. In the previous
example, the Global numbers for signals 65 to 96
on device 1 are 65601 to 65632. On device 2, the
signals 65 to 96 are expressed as D2, 65-96 in
universal numbering, but in global ID numbering
they are 131137 to 131168.
Global ID numbers precisely identify the origi-
nation or destination of each signal since the
console’s or rack’s device number is implied by
the global ID number. Thus every audio and logic
signal on a console, as well as every console bus
signal has a unique global ID number.
A Signal ID Calculator is included on the 99-
5000 CD-ROM and is also available from the Har-
ris FTP site (see page 5-1 for access) in the
customer_support/99-5000_CD-ROM folder. The
calculator is an Excel file to list local number ver-
sus Global number for every signal on a console
by entering the console’s device number.
Whenever a signal ID is required in a session
file to identify a signal, either the universal or the
global ID can be used. If the entry refers to a local
signal then only the local signal number is re-
quired, as in assigning local Net Card inputs to a
channel-specific include list, only the local num-
ber is required although using the universal num-
ber or the global ID number will also work.
SESSION FILE SECTIONS
Session files consist of sections. Each section
begins with a section header followed by one or
more entries. The following sections highlight the
typical sections found in session files.
Information Section
The information section header [Informa-
tion] is used to provide a brief description of
the file. The default description must be manually
edited to add information on how or why the ses-
sion file was created (e.g., sets the console
to prerecord network feeds).
To change the file description, scroll down to
the line that begins with Description=. Edit
the existing description. If required, additional
comments can be placed anywhere in the session
file when proceeded by a ; (semicolon). Comments
help clarify session file settings to other users.
