The Vortex has been designed to be configured with a PC via the RS-232 port and the included Conference Composer software and
then operated with the RS-232 connected to a remote control system. As with previous EF products, multiple devices can be
linked together and controlled via a single RS-232 connection. All functions of the Vortex can be controlled via RS-232. It is also
possible to download new firmware into the Vortex via RS-232.
The Conference Composer software makes it extremely easy to configure features and makes it possible to save configurations to
disk and to restore configurations.
Please note that while an external control system is not required (because many of the functions of the product are accessible via
the contact closures by assigning functions or macros to pins) it is often desirable to have an external controller particularly in an
installation with other equipment.
All commands to the product are executed in real-time, e.g., device settings are updated immediately. A document describing the
entire command set of the product and programming tips is available in the Conference Composer software help file This
document is also available on the CD that is shipped with the Vortex.
Each command name can be from 1 to 7 characters long followed by the specific arguments. Command names will be specific to
device types as some products have an integrated telephony interface and others don't. There are some commands, such as PING,
that are common among the various command sets. The Vortex sends status messages via RS-232 and EF Bus any time one of its
internal parameters changes. This means that the host program does not need to continually poll the Vortex in order to detect
status changes. Status messages are in the same format as the commands used to set the corresponding parameter.
A powerful feature of the command set is the ability to use wildcards which allows you to affect multiple channels with a single
command or to query the status of multiple channels and return an array status message. Another powerful feature is the absolute
and relative parameter settings. Now you can set a gain value absolutely, or change it relative to its current value. A list of the
commands is included in the programmers reference guide.
