2.4.11. Retry Time Out
Retry Time Out
Setting Description
Default Setting 255
Options Any number between 0 and 255 in MultiPoint networks.
Note: The minimum in 900MHz radios is 8 seconds.
Any number between 151 and 255 in Point-to-Point networks.
Terminal Menu (3) Edit Transmission Characteristics > (8) RetryTime Out
Description: The Retry Time Out parameter in a Slave or Repeater sets the delay the unit
waits before dropping the connection to a Master or Repeater.
l The factory default is set at the maximum of 255.
l With a setting of 255, the Master allows a Slave or Repeater to stay
connected as long as 1 packet in 255 is successfully received at the
Master.
l The maximum setting means that if 1packet in 255is sent successfully from
the Master to the Slave or Repeater, the link is maintained.
l This allows a Slave or Repeater to drop a connection if less than 1 in 8
consecutive packets is successfully received from the Master.
The Retry Time Out parameter is useful when a MultiPoint network has a roving
Master or Slave. As the link gets weaker, a lower setting allows a poor link to
break in search of a stronger one.
FREEWAVE Recommends: Setting the Retry Time Out parameter to
20 in the MultiPoint Master is recommended in areas where several
FreeWave networks exist.
This recommended setting allows Slaves and Repeaters to drop the
connection if the link becomes too weak, while at the same time prevent
errant disconnects due to interference from neighboring networks.
Note: While intended primarily for MultiPoint networks, the Retry Time
Out parameter may be changed in Point-to-Point networks.
However, the value in Point-to-Point mode should NOT be set to less than
151.
