(3) Xmit Rate
There are two settings for the Transmit Rate parameter. For normal operation
FreeWave should be set at Transmit Rate 1. Transmit Rate 0 is useful to
qualitatively gauge signal strength. When set to Transmit Rate 0 the Transceivers
will transmit data back and forth continuously, and the strength of the signal may
be gauged by the Clear to Send LED. A solid red Clear to Send LED indicates a
strong signal, the less the LED is on the weaker the signal.
Because the Transceivers transmit continuously when Transmit Rate is set to 0
(whether or not they have data to send) they use radio frequency spectrum
unnecessarily. Therefore, in point-to-point operation, Transmit Rate 0 should be
used only as a diagnostic tool and not for normal operation.
(4) RF Data Rate
FreeWave has two settings for the RF Data Rate (not to be confused with the
RS232 Baud Rate). Setting 2 should be used when the transceivers are close
together and data throughput is to be optimized. Setting 2 must also be used
when full throughput of 115.2 KBaud is necessary. Setting 3 should be used when
the transceivers are farther away and a solid data link is preferred over data
throughput.
Note: When using the transceivers in Multipoint mode, the RF Data Rate setting
must be identical for all units in the system. Any transceiver with a
different RF Data Rate than the master will not establish a communication
link.
