I've Tried Everything And I Still Can't Connect To The SoundStructure Device

Reboot the SoundStructure device and see if it is possible to connect to the device either via RS-232 or

Ethernet. If so, check the Polycom website for a newer version of firmware and release notes to see what

issues may be been resolved.

RS-232 Troubleshooting

I Can't Connect Over RS-232 To The System, How Do I Connect?

Check that the baud rate between the PC or Control system and the SoundStructure device are set to the

same value. Baud rates above 9,600 baud should have hardware flow control enabled on both the

SoundStructure device and the control system or local PC.

How Do I Set The Baud Rate? What If I Can't Connect Over RS-232?

By default the baud rate of the SoundStructure devices is set to 9600 bps. Try connecting the device at this

baud rate over the serial port.

There is an API command ser_baud that can be used to set the baud rate of the SoundStructure device. To

adjust baud rate, send the command

set ser_baud 1 9600

where 1 is the device ID of the device.

Remember if you change the baud rate and are connected over RS-232 at the previous baud rate, you will

have to change the baud rate on your PC terminal program or Control System to continue talking to the

device over the RS-232 interface.

The RS-232 cable requires straight through wiring as shown in

Creating Advanced

Applications.

The baud rate may be set using either the Ethernet interface or RS-232 interface. Connect to the device as

described in
