Max Priority
This value is used to adjust Wlan performance and should be set to 20.
Base Priority
The Base Priority parameter determines the number of priority transmit slots
reserved for each base station. The allowable range for this parameter is 0 to 100.
For optimal performance, this parameter should be set to a value of 2.
Message Duration
This parameter controls the duration of transmit slots to optimize communications
and decrease the likelihood of collisions. A Message Duration value of 1
translates into a slot duration of 130 micro seconds. The allowable range for this
parameter is 2 to 200. For optimal performance, this parameter should be set to 15.
Offline Timeout
This parameter determines the time in minutes that a terminal is allowed to be inac-
tive before the 9150 declares it offline. An offline terminal is still considered part of
the system. Messages to offline terminals are queued at the 9150. The terminal
remains offline until it transmits any message. Values for this parameter range from
0 to 100. If the parameter is set to 0, terminals are never declared offline.

The pull-down menu shown for the Interfaces option on the 9150 Configuration
Main Menu page indicates which interfaces have been detected in use. For the selec-
tion “Slot A: Teklogix Narrowband”, entering the “Configure” dialog box will
display the Slot A TRX7370 Parameters menu for the TRX7370 Narrow Band PC
card radio, as shown in Figure 5.4 on page 107. The Slot A TRX7370 Parameters
menu has two configuration sub-menus:
“General Options”
When you select this sub-menu, the page displayed allows you to set the operat-
ing options for the 9150 in either base station or RRM mode, and to retrieve the
radio card’s permanent communications settings.
“Connectivity Options”
When you select this sub-menu, the 9150 displays the Parameters page of the
operating mode for which the 9150 is set (base station or RRM).
