Real Time Data Port (1135) 

Certain applications require that GPS data be retrieved in a timely manner.  For this purpose, Port 
1135  may  be  configured  to  provide  real-time  data  output.    Users  can  specify  which  logs  are 
output and users may request any of the ASCII logs specified in the user manual for the Novatel 
OEMV receiver (

http://www.novatel.com/support/docupdates.htm#oemv

).  See the 

log

 command. 

3.4.3.2 

Command Port (1700) 

System  commands  can  be  issued  to  the  ATS-6501  via  the  command  port.    These  commands 
provide  a  limited  set  of  operations  to  be  used  for  remote  control  of  the  system.    Typically,  a 
remote  monitoring  station may  record  an error that  indicates  user  intervention  is  required.   The 
remote  monitoring  station would then be  able  to  access  the  command  port  via  the  Ethernet and 
issue the commands required for recovering from the error.  The following list provides a short 
description of each command. 
 

Note:

  All commands are in lowercase and the commands 

are

 case sensitive.
