Configuration Protocol Configuration
4 - 5
The internal network number for the MSS is a four-byte number that defaults to the last four bytes
of the unit’s Ethernet address (for example, a3001234). It is unlikely that this number will need to
be changed. See Chapter 6, Commands for more information.
NOTE: The MSS should be rebooted if the internal network number is changed.
4.3.3 LAT Configuration
Three LAT parameters can be configured for the MSS: the server’s identification string, its service
group list, and its internal circuit timer.
4.3.3.1 Server Identification String
The MSS has a default name (mss_xxxxxx where xxxxxx represents the hardware address) that it
uses when announcing itself to the LAT network. Users can change the name string. Users can also
configure a more descriptive identification string. This string must be placed in quotes to preserve
case, spaces, or punctuation.

4.3.3.2 Service Groups
A service is any resource on the network that can be accessed locally or via a network connection,
for example, a modem. The MSS serial port and the services on the network each belong to one or
more service groups. When a user or device requests a connection to a service, the LAT host will
check the service groups to which both the requester and the service belong. If any group number
is common to both, the connection attempt will continue. If not, access will be denied.
The Change LAT Groups command establishes group numbers for the MSS and its serial port.
Figure 4-12: Changing Service Groups
NOTE: Each time the Change LAT Groups command is entered, the previous group list is
replaced.
4.3.3.3 Circuit Timer
Message transmission on LAT networks is controlled by timers. The MSS circuit timer specifies
when messages will be sent from the server to other network nodes. This timer value is set to a
widely-used default at the factory and should not be changed unless necessary.
If you need to change the length of the circuit timer, use the Change LAT CircTimer command
followed by a timer value integer. The timer value can range from 30 to 200 milliseconds.
