Narrow Band Radio Parameters

Base Priority (TekLAN 2.4 GHz)
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 (TekLAN 2.4 GHz)
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.

4.2.2 Narrow Band Radio Parameters

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 open
the parameters pages for the TRX7370 Narrow Band PC card radio. These pages list
the polling protocol and radio parameters, and show the radio card's permanent
communications settings.
