What Is Flow Control And How Does It Work?
Hardware flow control on the SoundStructure device requires two additional
handshaking signals, CTS and RTS, in the RS-232 cable to ensure data is
received before additional data is sent. This prevents the serial port from drop-
ping data due to not being ready for new data. Flow control literally controls
the flow of data between two serial devices.
If hardware flow control is used - and it is recommended that you use flow
control on data rates above 9600 baud - then it should be enabled on both the
SoundStructure device and the device that is connected to the SoundStructure
device.
Hardware flow control may be enabled on a SoundStructure device with the
API command
set ser_flow 1 hw
and may be removed with the command
set ser_flow 1 none
where 1 is the device ID.

How Do I Know The Polycom HDX System Is Connected Properly To The
SoundStructure?
The Polycom HDX Diagnostics and System Status screen shows whether the
SoundStructure device (labeled as Polycom Mixer) has been detected. A green
arrow associated with the Polycom Mixer, as shown in the following figure,
indicates the systems have detected each other and are working properly.
Alternatively if the message appears as below, then the two systems have not
detected each other and are not communicating over Conference Link2.
If the SoundStructure system hasn’t been detected by the HDX, then remove
the CLink2 cable from the rear of the SoundStructure device and reconnect it.
Refresh the HDX UI page by moving from the page and then back to the page.
