Figure 8: The Development Board Level Adjust Section
The right position puts the module into receive mode. The yellow RX LED
lights up and data received by the module is output on the yellow
DATA_OUT test point.
These two configurations allow the module to transmit and receive custom
data while controlling the baud band and channel with the frequency dials
on the board. It is similar to the Prototype Area, but requires less external
circuitry to configure the module. The switches on the board are used for
hardware configuration in this mode.
The Baud Rate Control dial sets the BAUD0 and BAUD1 lines to configure
the module's baud band. This should be set the same on both boards for
proper operation.
The Channel Control dial sets the CHAN_SEL0, CHAN_SEL1 and
CHAN_SEL2 lines to configure the module's channel. This should be set
the same on both boards for proper operation.
An LED bar is used to provide a general indication of the RF signal
strength. The closer the active LED is to the top, the stronger the received
signal level. The receiver must be active for at least one second for the
RSSI level to update.
The center position on the Evaluation Select switch activates the Range
Test Area, allowing the link's range to be evaluated. This area is described
in detail in the Range Test Area section of this user's guide.
