Security Feature
The RS-232 port is often connected to a public telephone line which could compromise
instrument security. If the LOGON feature is implemented the port has the following attributes:
1. A password is required before the port will operate.
2. If the port is inactive for 1 hour, it will automatically LOGOFF.
3. Repeat attempts at logging on with incorrect passwords will cause subsequent logins
(even with the correct password) to be disabled for 1 hour.
4. If not logged on, the only command that is active is the '?'.
5. The following messages will be given at logon.
LOG ON SUCCESSFUL
Correct password given
LOG ON FAILED
Password not given or incorrect
LOG OFF SUCCESSFUL
Logged off
The RS-232 LOGON feature must be enabled from the front panel by setting bit 4. See
Table 6-4. Once the feature is enabled, to logon type:
LOGON 940331
940331 is the default password. The password can be changed to any number from 0 to 999999
by the variable RS232_PASS. To change the password enter the command:
V RS232_PASS=NNNNNN
which sets the password to the value NNNNNN.
