Set Slot Assignment Mode (base station only) 
Sets whether the base station will assign remote transmit slots dynamically, based on the 
number of remotes currently registered or whether the base station will assign remote 
transmit slots staticly, based on the maximum number of remotes parameter. If static slot 
assignment is selected, make sure maximum number of remotes is correctly set. 
Otherwise remote transmit performance will suffer as transmit time will be reserved for 
remotes that may not exist. The dynamic assignment mode will generally be preferred; 
however, the static assignment mode will result in a static maximum data length  
parameter. 
 
Set Base Slot Size (base station only) 
Sets the amount of time allocated for transmission on each hop for the base station time 
slot in 4-byte increments.  Maximum value is 
34H
 which corresponds to 208 bytes. (34H 
= 52D x 4 = 208) If using a protocol mode, attempting to send a packet with a length 
longer than this setting will cause the packet to be discarded.  
 
Set ARQ Mode 
Sets ARQ mode when set to 0 which is the default.  In this mode the radio will resend an 
unsuccessful transmission until either successful or packet attempt limit attempts have 
been made.  When set to 1 selects redundant transmit mode that will send every 
transmission packet attempt limit times regardless of success or failure of any given 
attempt. When redundant transmit mode is used, receiving radios will discard all 
subsequent retransmissions once the transmission has been successfully received. Thus 
the receiving host will receive just one copy of the transmission.
