SIMPLWINDOWS NAME: Vortex Single Channel Mic Input Control with Setup
MANUFACTURER: Polycom
CATEGORY: MIXER
VERSION: 1.0
SUMMARY: Allows control of a single channel of mic input gain and setup
parameters.
GENERAL NOTES: The commands used for the Polycom Vortex may be similar
to commands used for other Polycom Installed Voice products. Therefore, the same modules
developed for the Vortex may work on other products. To allow for
this flexibility of use, you must specify which model is being
controlled using the TYPE-ID-HEX parameter field. This must be a 2 digit
hex representation of the model type as defined by Polycom. For the Vortex,
the model type is F, therefore the parameter value to use is 46 which
is the hex representation of the letter F. This can be seen by
checking any standard ASCII chart. There should be no suffix used after
the 46.
Multiple devices can be connected to the ASPI bus and controlled from
a single RS232 port. Therefore, it is also necessary to enter the Unit ID
of the device being controlled. This should be entered in the
UNIT-ID-ASCII parameter field as a two digit number from 00-07 with no suffix.
You must specify which channel you want the module to control using the
CHANNEL-ID-HEX parameter. Valid channel ranges are 1-8 and A-D. These must
be entered as 2 digit hex representations of the channel with no suffix.
So for channel 1, enter 31, for channel 4, enter 34, for channel B, enter 42.
This can be seen by checking any standard ASCII chart.
This module was designed to operate on a single input channel. The
channel can be ramped up/down with buttons, or with a slider object. Mute
and Automatic Gain Control (AGC) can also be controlled. In addition, the
following mic settings can also be adjusted for Mic type inputs:
Phantom Power (PHANTOM)
This module can also be used in conjunction with the Vortex
Feedback Processor Module to monitor the state of all parameters. A
properly constructed program would consist of a single Vortex
Feedback Processor Module receiving information from the com port. The
output of this module would be connected to the FROM-ASPI-PROCESSOR$
inputs of as many other Vortex modules are in the program. The
Processor module will reformat the data into the format that the
remaining Vortex modules are programmed for.
Upon startup of the Crestron system, it may be desired to pulse the
POLL-* inputs. This will request the current settings for the selected
channel, so the feedback can be properly displayed. After this point, the
POLL-* inputs should not need to be used, except after recalling a preset.
Note that if it is desired to control multiple channels of volume
simultaneously, it is recommended to set up Macros on the system.
A macro can be set up to adjust multiple channels simultaneously. By
repeatadly triggering the Macro from the Crestron system, we can control
multiple channels. See the demo program for an example of how this is
programmed.
