times every transmission will be sent, regardless of success or failure of a given attempt. 
When this parameter is set to 

, RF flow control mode is entered for transmissions from 

the radio (See Section 2.3.4). This mode can be entered for one or both radios in a point-to-
point system. When used in a point-to-point system the 

 parameter should be set to 1. 

Using this mode in a point-to-multipoint system will stop transmissions to all radios when 
any one radio has a full buffer or if the base radio attempts to send data to a remote that has 
recently (<2.5 seconds) left the range of the base.  
 
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 52.1µs increments, corresponding to 8 bytes per unit.  Default value is 

 which 

corresponds to 2,816 bytes. 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 

 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.
