Troubleshoot Network Communications 
 
Before  you  change  your  network  configuration,  ensure  a  firewall  is  NOT 
responsible  for  your  communication  difficulties.  Temporarily  disable  any 
active  firewalls  (e.g.  Windows  Firewall)  or  check  the  application 
masvb32.exe  has  permission  to  access  your  network  through  your 
firewall  (i.e.  it  has  an  exception  rule  applied  to  it). 
 
When  you  use  cabled  Ethernet  (RJ45),  your  instrument  and  Ascent  use  a 
default  network  address  to  communicate.  Usually  you  will  NOT  need  to 
change  this.  However,  it  is  possible  that  this  address  may  interact 
negatively  with  other  devices  on  a  network.  This  conflict  may  result  in 
other  network  connections  being  lost  while  your  instrument  is  connected 
to  your  computer.  
 
To  resolve  this  conflict,  change  the  Ethernet  network  settings  in  your 
instrument  and  Ascent. 
 
NOTE: Your changes will only take effect once your instrument 
hardware has been reset. 
 
If  you  change  the  network  address,  you  must  change  it  in your 
instrument  and  software  so  the  two  can  communicate.   
 
NOTE: This does NOT apply if you are only changing the last digit 
of the IP address.
