Free Window Factor
The value entered in this parameter determines if “free window mode” will be used. In free
window mode, all mobile computers that are not assigned any other window can use the free
window.
Entering a value of
0 (zero) in this parameter disables free window mode. Increasing the
value of this parameter increases the likelihood of a message being transmitted in the free
window.
Message Mode Limit
This parameter defines an upper limit to the number of messages that must be queued for
transmission before message mode polling starts. Accepted values range from
0 to 7 , where
0 disables message mode.
Note: The number of mobile computers and past events are also part of the algorithm that
determines whether or not to start message mode.
Callsign Period
A call sign is periodically transmitted as an audible Morse code signal. This parameter spec-
ifies the interval in minutes between call sign transmissions. Acceptable values range from
0
to 60 . The federal agencies, Industry Canada and the Federal Communications Commis-
sion in the United States, require that each system transmit its own identification call sign
every 15 minutes.
In countries where a call sign is not required, setting this parameter to
0 prevents the trans-
mission of any call signs, allowing for shorter poll time-outs in mobile computers and faster
channel switching.
Callsign String
This string can be a maximum of 10 characters long. All characters are either numbers or
letters. The prefix “DE” (from) is added to the beginning of the transmitted call sign.
