Error #2048: Security sandbox violation

I am using sockets trying to connect to a piece of hardware on my local network.?I can connect to the socket but as soon as I try to send some data to the socket and wait for the response I get the following error.

Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: app:/index.html cannot load data from 192.168.1.204:44444.
?at ResourceLoader/nativeReceivedAllData()
?at ResourceLoader/receivedAllData()
?at ResourceLoader/onLoadSWFComplete()

After searching I've seen some people talk about a security policy file, but it's not possible for me to place this file on the hardware.?Plus the IP address could change.

Can anyone help out??Thanks.
