IO Slave
Transmission Characteristics-
(Figure 18)
Max Packet Size and Min Packet Size–
The FGRIO System requires a minimum com-
bined packet size of 48 Bytes. See Figure 6 (pg. 10) for a list of available packet sizes that
can be used.
RF Data Rate -
The RF Data Rate must be set to “Normal” (3) when using the FGRIO
System. This is for applications that are stand alone or when integrated into an existing FGR
network.
Retry Timeout–
By lowering the Retry Timeout, the inactive link time between the FGRIO
Master and IO Slave can be reduced when going from autonomous mode to connecting
back to the FGR Network. If the Network Master goes down, the IO Master and Slave will
continue to operate in autonomous mode. When the Network Master comes back up, the
FRGIO Master will break the link with the IO Slave to reestablish a link with the Network
Master. Once the FGRIO Master is linked to the Network Master, then the IO Slave will be
able to link back to the FGRIO Master. With a lower Retry Timeout setting, it will take less
time for the IO Slave to link to the FGRIO Master.
