INTRODUCTION ORBAN MODEL 1101
The Control Application connects (through the server) to only one card at a time,
allowing you to recall, edit and save presets, set input/output mix levels, and do
other housekeeping tasks for that card.
Note that the Control Application does not use the server to interface
with a card installed on the same computer that is running the Control
Application.
“Simple” operation occurs when the Service’s remote server is disabled. For “net-
work” operation, you may use the Optimod Control Application to set pass-
words at a given OPTIMOD-PC card’s host computer to protect it from unauthorized
access from the network. You also need to make your local cards visible to the net-
work by selecting “Allow Network to Access Local Cards” in the “Card and Security
Administration” screen, which is accessible from the Tools drop down menu box.
The setup instructions in Section 2 of this manual provide detailed instructions on
how to do this.
In a Simple or Network environment, the number of OPTIMOD-PC cards that one
host can accommodate depends only on the number of free PCI slots available and
on the speed of the host’s CPU. (PCI expansion chassis are supported.) OPTIMOD-PC
cards share IRQs, so availability of IRQs will not usually be a problem.
Although OPTIMOD-PC contains on-board DSP, the host’s CPU must still perform
some “housekeeping” chores. It must run Orban’s server software, and, more signifi-
cantly, it must do sample rate conversion if OPTIMOD-PC is used as a WAVE device
and the source or destination sample rates are different from 48 kHz. On the other
hand, if only OPTIMOD-PC’s analog input and/or AES3 digital I/O are used for input
and output, then OPTIMOD-PC’s built-in hardware sample rate converters do all
necessary conversion and no extra load is placed on the host CPU for sample rate
conversion.
