8.4.  PASSWORD SECURITY FOR SERIAL REMOTE 
COMMUNICATIONS 
In order to provide security for remote access of the T300/T300M, a LOGON feature 
can be enabled to require a password before the instrument will accept commands.  This 
is done by turning on the SECURITY MODE (Mode 4, Table 6-1). Once the 
SECURITY MODE is enabled, the following items apply. 
  A password is required before the port will respond or pass on commands. 
  If the port is inactive for one hour, it will automatically logoff, which can also be 
achieved with the LOGOFF command. 
  Three unsuccessful attempts to log on with an incorrect password will cause 
subsequent logins to be disabled for 1 hour, even if the correct password is used. 
  If not logged on, the only active command is the '?' request for the help screen. 
  The following messages will be returned at logon: 
  LOGON SUCCESSFUL - Correct password given 
  LOGON FAILED - Password not given or incorrect 
  LOGOFF SUCCESSFUL - Connection terminated successfully 
 
To log on to the T300/T300M Analyzer with SECURITY MODE feature enabled, 
type: 
LOGON 940331 
940331 is the default password. To change the default password, use the variable RS-
232_PASS issued as follows: 
V RS-232_PASS=NNNNNN 
Where N is any numeral between 0 and 9.
