13) Appendix B: RF
In order to configure RF communication you need to set the baud rate and channel on
both sides of the RF.
1.
Configuration (DIP 1) : In order to configure new parameters: move DIP switch
to 'on' state, arrange all parameters according to the following section, press reset,
wait until LED RX is off. Move Config to OFF.
2. Baud rate (DIP 2, 3) : Baud rate is the communication bit rate beetween
PC/controller and the RFC/RFR – the UART default baud rate is 9600bps. All
states are summarized in
Table 4 .
Table 2: Baud rate states
If RFR is being used and the connection is to several controllers in different
distances, you should reduce baud rate until you establish connection with no
errors. The 19200 bps is not recommended for use.
3. Address (DIP 4, 5) : for future use. Note that it must be at OFF position.
4. Channel (DIP 6, 7, 8 )
:
Set the module’s hopping channel number (see Fig. 76 ). A
channel is one of three layers of addressing available to the XStream radio
modem. In order to module to communicate with each other, the modules must
have the same channel number since each network uses a different hopping
sequence. Different channels can be used to prevent modules in one network from
listening to transmissions of another.
Table 4 summarizes all possible Jumper
modes.
Note that it is very important to verify no communication disturbance occurs in
neighboring farms.
