22.3.3.1 Polling Protocol Parameters
Number of Poll Windows
This parameter defines the number of poll windows the 9160 G2 will use. The value
assigned to this parameter is dependent on the number of terminals and the radio
link protocol used. Table 22.5 indicates how the value assigned to the Number of
Poll Windows parameter is determined.
Size of Poll Windows
The value assigned to this parameter determines the largest message that can be
passed between the 9160 G2 and the terminal in a normal poll window. The window
size can be adjusted to accommodate anywhere from 5 to 32 characters.
Larger windows increase the polling period and can increase the response time.
Smaller windows increase the number of message and long message polls, and can
also increase the response time.
Important: In “Cellular” mode, the minimum value for this parameter is 8.
