Appendix 2: General Notes About NfRemote    

Below are several notes about using NfRemote. 
 

•

 

Multiple computers can connect to the same AERO.10/100/2000 unit simultaneously.  

•

 

One computer can connect to multiple AERO.10/100/2000/ units simultaneously by 
running NfRemote multiple times on the same PC.  This is a handy feature for 
monitoring or adjusting main and backup units at the same facility or monitoring and/or 
configuring units assigned to multiple channels or different stations.  

•

 

Each instance of a remote connection requires some horsepower from AERO.100’s CPU.  
Observe the CPU load and do not exceed 80% even for short periods of time. 

•

 

Tasks that require significant CPU resources include; using multiple instances of the 
oscilloscope and streaming client audio to multiple remote computers.  Although it is 
highly unlikely that your AERO.100 CPU would run out of resources, even in a fully 
configured unit addressed from several remote computers, it is important to monitor 
the AERO’s CPU load!  Fortunately, the CPU percentage meter will warn you when 
resources begin to run low. 

•

 

The available bandwidth on the local network determines how robust the remote 
connection will be. 
 

•

 

The remote software measures available network resources during the initial handshake 
with AERO.100.  If bandwidth is marginal, some patch points may be unavailable for 
remote monitoring of the oscilloscope and spectrum analyzer. 
 

•

 

The quality of the client audio streamed to a remote computer will be adjusted to best 
match current network resources.  
 

•

 

The latest version of NfRemote is always included with any software or firmware 
upgrade.  Only the latest version of NfRemote will provide all of the interface features 
that the latest software and firmware provide.  Always update all copies of NfRemote 
with the latest version after an upgrade.  Newer versions of NfRemote are compatible 
with older software revisions of AERO.10/100/2000.
