Security Feature
The RS-232 port can be 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 LOGOUT.
3. Repeat attempts at logging on with incorrect passwords will cause subsequent logins to be
disabled for 1 hour.
4. If not logged on, the only command that is active is the "?". If this command is issued the
M200AH will respond with MUST LOG ON.
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 from
Table 5-9. Once the feature is enabled, to logon type:
