Set Packet Retries
This is the
radio will attempt to send an unsuccessful transmission before discarding it. If ARQ
Mode is set to 1, it is the number of times every transmission will be sent, regardless
of success or failure of a given attempt. When this parameter is set to 255, RF flow
control mode is entered for transmissions from the radio. This mode can be entered
for one or both radios in a point-to-point system. Using this mode in a point-to-
multipoint system will stop transmissions to all radios when any one radio has a full
buffer.
Set Hop Duration
This is the
frequency channel. A smaller value will allow the remote to lock on to the base
signal faster at system startup, and will generally decrease packet latency. A larger
value increases network capacity, due to decreased overhead in channel switching.
This Set Hop Duration value only needs to be set in the base which broadcasts the
parameter to all remotes. However, link time can be reduced if this value is also
programmed into the remotes, which use it as a starting value when scanning for the
base.
The speed at which the radio hops affects both latency and throughput. The faster the
radio hops, the shorter the latency but the lower the throughput. The minimum packet
length and packet timeout allow fixed-length packets of data to be transmitted on a
single hop without leaving data stuck in the radio's transmit buffer.
NOTE: If the hop speed is too fast, there may not be time to send a long packet on a
single hop.
