Murata Electronics North America 2410G User Manual

of 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 Data Transmit Delay
When used in conjunction with the minimum data length parameter, this sets the amount
of time from the receipt of a first byte of data from the host until the radio will transmit in
transparent mode.  Default is 

00H

 which causes transmission to occur without any delay.

When a host is sending a group of data that needs to be sent together, setting this
parameter will provide time for the group of data to be sent by the host before the radio
transmits.  If the length of data to be sent together is longer than the time slot can send,
the data will not be sent together but will be broken up over multiple hops.  The length of
time the radio will wait is equal to the specified value times the hop duration.

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 statically, 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 69.4µs increments, corresponding to 4 bytes per unit.  Maximum value is 

which corresponds to 208 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 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.
