L3 Nova Engineering NovaRoam MH902 User Manual page 11

The Serial Port Tab is only available when DNP is selected as the serial port mode. The Serial Port Tab
is used to configure the communication parameters for the NovaRoam's serial port. The following
parameters can be configured:
•
Baud Rate. Determines the bit rate used for serial communications. The default value is 9600.
•
Data Bits. Determines the number of data bits within each character. The default value is 8.
•
Parity. Determines the setting for the parity bit within each character. The default value is none.
•
Stop Bits. Determines the number of stop bits that follow each character. The default value is 1.
•
Flow Control. Configures the type of flow control that is used for serial data communication. The
default value is none.
IP Routing Page
The IP Routing Page provides a list of tabs that can be used to configure the routing performance of the
NovaRoam. Selecting a tab will provide a list of configurable options.
Ad Hoc Routing Tab
The Ad Hoc Routing Tab is used to enable, disable, or configure the embedded ad hoc (mesh) routing
protocol. The embedded ad hoc routing protocol is a customized version of Ad-Hoc On-Demand
Distance Vector (AODV). The following parameters can be configured:
•
Off. Selecting Off will disable the automated mesh networking protocol. When disabled, static
routes must be entered manually on the Routes tab
•
AODV. Selecting AODV will enable the embedded mesh networking protocol allowing network
routes to be created and maintained automatically. All radios in the network must enable AODV
to utilize the feature. Selecting AODV is recommended. The remaining configuration options on
the Ad Hoc Routing tab pertain specifically to the mesh networking protocol.
•
Active Route Timeout. The Active Route Timeout parameter determines how long a NovaRoam
should wait for an inactive data communication route to be removed from the route table. Each
time an IP packet is sent over a specific route, a timer begins counting down. If the timer expires
before another packet is sent, the route is considered inactive and is removed from the radio's
route table. The Active Route Timeout value determines the length of this timer. The value of
this parameter is measured in minutes and has a default value of 30 minutes.
•
Hello Interval. The Hello interval setting determines how frequently the NovaRoam broadcasts a
neighbor beacon message (hello message). Smaller hello interval values increase the wireless
network's responsiveness to routing changes but do so at the expense of creating additional
