ENERAL NFORMATION
The ViewStation SP / SP384 does not have a separate mixer input unlike the other ViewStation products.
As a result, the audio that is sent into the VCR input will be routed to the Monitor output of the ViewStation
SP / SP384. This will cause the local side of the video call to hear their audio via the local loudspeakers.
Because of this limitation, we do not recommend the use of the ViewStation SP / SP384 with Vortex
Devices.

NPUTS AND
In order to send and receive audio to the Polycom ViewStation 128, H.323, MP, or 512 codec, you need to
observe the following procedure:
1. Make sure that the ViewStation codec has firmware version 7.5 or higher installed in it. You can
find this information on the System Info page.
We do not recommend using a ViewStation 128, H.323, MP, or 512 codec with a Vortex
device unless the ViewStation has firmware version 7.5 or higher because the
internal echo canceller of the ViewStation could not be disabled in previous versions.
2. Connect one of the Outputs of the Vortex device to the mixer input of the codec. By default,
Outputs A-C of the Vortex device are mix-minus versions of the Inputs A-C signals.
