Appendix D. Setting Up RF401-to-CR206(X) Communications
6. Address: Enter 0 if the RF Protocol setting is PakBus. If the RF Protocol
setting is Transparent, enter a number from 0 to 1023. This number must
match the Radio Address setting for all RF401 radios in the network. The
Address setting must also match the setting for all other CR206(X)
dataloggers in the network.
7. Power Mode: Enter a radio “Power Mode” that works with the RF401's
power mode (see TABLE D-1). Typically, the power mode setting should
be "1 Sec with Long Header" or "8 Sec with Long Header". Although
these power modes introduce 1 second or 8 seconds (respectively) of
latency, they use less power than the "always on" modes. With settings
other than “always on”, the radio receivers turn on periodically for 100
milliseconds. It is therefore necessary for the transmitting radio to send a
long header to assure that the duty cycling receiver on the other end hears
it (see FIGURE D-2 and FIGURE D-3).
