Appendix A: Security Access MXU2
Manual
23
1. Free Access: All users have free access to all channels. The only security is the login user
name and password—if used. Setting security classes have no effect when this mode is
invoked. Free Access is the default setting.
2. Exact Match: The user’s security class must be exactly the same as the channel security
class in order for the user to access the channel.
• Example: If the user’s security class is B1, then they will be able to access only the
computer with the channel security class of B1. All other computers with security class
settings other than B1 will not be accessible in Exact Match security mode.
3. 2 Digit Level: Once a user’s security class is designated, that user can access all computers
that have equal or lower channel security class designations.
( Example
: User’s security class = D5. User can access channel D5 and all lower
channels D6 through P9 (Figure 18).
4. Level/Group: Once a user’s security class is designated, that user can access a computer:
• with the exact same security class designation
• with a lower level (letter) channel security class designation
• with the same level (letter) designation and the group zero.
( Example
: User’s security class = D5. User can access channel D5, all lower
levelsE0 through P9, and D0 (Figure 18) .
