NET CARD
Only BMX
digital
consoles with the optional Net
Card installed can directly communicate with and
control a VistaMax system. The Net Card (shown
below) plugs into the motherboard at the right
rear corner of the mainframe, behind the output
modules. It is hidden by the meter panel in nor-
mal use. There are two talkback level trim con-
trols on the card to set control room and producer
talkback levels at installation. A blank panel cov-
ers the Net Card slot when the card is not present.
Without the Net Card, a BMX
digital
console is
treated like any other console connected to a Vis-
taMax system: input channel sources and console
outputs must connect to VistaMax frame I/O in-
puts while I/O card outputs connect to the con-
sole inputs. Any in-room devices connected directly
to the console would only be available through a
bus output connection. VistaMax selector panels
would then be used to select the input sources for
the console inputs tied to the VistaMax.
With the addition of the Net Card, the BMX-
digital
console is integrated into the VistaMax sys-
tem. A Net Card functions as the audio, logic and
control interface between the entire console and
the VistaMax system through the two Facet con-
nectors. It automatically makes available to the
VistaMax system any, or all, of the console input
sources and console bus outputs.
The Net Card also provides eight local audio
sources (four analog and four digital inputs) and
eight local destinations (four analog and four digi-
tal outputs) for the VistaMax system.
Some typical uses of the Net Card outputs in-
clude routing analog audio to the External Moni-
tor inputs on the control room module, VistaMax
intercom talk into the External Talk input, and
for in-room recording equipment.
The Net Card inputs can connect Talk from Ex-
ternal audio into the VistaMax system along with
outputs of in-room equipment that do not require
an input channel on the console yet still need to
be made available throughout the facility through
the VistaMax system.
The two Facet connections (CAT-5e, as shown
above, or alternately Optical connections, not
shown) each simultaneously send 64 signals to the
VistaMax frame with 64 return signals coming
from the VistaMax frame. Each signal may con-
sist of: one channel of audio; any number of com-
mon logic commands; or it can be an audio signal
with logic “bound” to the audio.
Although only one facet cable is required to tie
the BMX
digital
into the VistaMax system, both
facet connections can be used to double the signal
carrying capability (128 signals coming from the
console with another 128 signals returning to the
console) or for connection redundancy.
Refer to the VistaMax manual (75-52) for addi-
tional connection and applications information.
NET-ONLY MODULES
These are input modules that do not have any
of the external audio or logic connections found
on the full-featured and limited-feature input mod-
ules. They are designed to directly interface with a
