B.2 Example 2: PC-to-RF Network with Repeater
In this example, the master radio is connected to a PC running LoggerNet (see
FIGURE B-3 ). Slave radios are connected to CR1000s in the field. One slave
radio, also connected to a CR1000, is used as a repeater to go around an
obstacle such as a hill. To take advantage of the low power mode, those
devices that are NOT repeaters should be configured as multi-point slaves and
not as multi-point slave/repeaters. In this configuration, it may be desirable to
use an external omnidirectional antenna at the repeater.
Note that when a repeater is used, the RF throughput is cut in half. However,
when more than one repeater is used, there is no further degradation in the RF
throughput of the link. Throughput is the rate at which data is sent or received.
Reducing throughput means less data can be transmitted in a specified amount
of time.
Remember, each datalogger must have a unique PakBus address.
