CHANNEL SETTINGS
Maximum Packet Size (Bytes)
This parameter sets the maximum over-the-air packet size in bytes. A smaller maximum Packet Size is
beneficial when many remote radios are trying to access the channel, and smaller high priority packets must
not be delayed by larger low priority packets sent by other radios. The default setting is 1550 bytes.
This packet size includes the wireless protocol header and security payload (0 to 16 bytes). The length of
the security header depends on the level of security selected.
When the security setting is 0, the maximum user data transfer over-the-air is 1516 bytes.
When encryption is enabled, the entire packet of user data (payload) is encrypted. If authentication is being
used, the security frame will be added (up to 16 bytes). The wireless protocol header is then added which
is proprietary to the Aprisa SRi. This is not encrypted.
