7.1.7.5. COM Port Password Security 
In order to provide security for remote access of the T703, 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, Section 7.1.4).  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 T703 calibrator with SECURITY MODE feature enabled, type: 
LOGON 940331 
940331 is the default password.  To change the default password, use the variable RS232_PASS issued as 
follows: 
V RS232_PASS=NNNNNN 
Where N is any numeral between 0 and 9.
