Note: Irrespective of the Freq Key used, all transceivers in either point to point or point
to multipoint networks must be set to identical Hop Tables and Table Size (number of
frequencies).
Frequency Zones
Frequency Zones allow the user to create a custom hopping table by specifying the
portion of the band available for the radio to use. The band is divided into sixteen (16)
zones, each covering seven of the 112 available channels. A zone is enabled by setting
its value to 1 and disabled by setting its value to 0. For all 112 channels to be available,
the Hop Table must first be set to 0, the Standard Hop Table. All radios in a given
network must have the same selection for Hop Table and Zones to be able to
communicate successfully.
Max Packet Size and Min Packet Size (Menu Options 1,2)
Options (1) and (2) allow the user to designate the size of the packets (in bytes) used by
the transceiver in its communication link. It should be noted that in Point to Point modes
the Max and Min Packet Settings will not have any material impact on throughput unless
115.2 KBaud is desired. The settings for Min and Max Packet size
MUST
be the same
for every wireless data transceiver in a given network.
The combination of Max and Min Packet Size Settings determines the allocation of the
communication link from the Master to the Slave and vice versa. With a given Max
Packet Setting the master will transmit up to that number of bytes on every hop. If fewer
than that number of bytes is transmitted the balance is allocated to the slave's
transmission, in addition to the quantity in the Min Packet Size Setting.
Packet size is determined by a combination of the setting entered by the user and the RF
Data Rate.
Table 2-3
,
Table 2-4
, and
Table 2-5
provide the packet sizes for each
different combination of settings.
