b. For the datalogger settings, set the Baud Rate to match the radio’s RS-232

baud rate. The datalogger “Extra Response Time” can be left at 0 (see

Figure 5).

For safety, maintain 20 cm (8 inches) distance between

antenna and any nearby persons while the radio is

transmitting.

CAUTION

FIGURE 5. The Baud Rate in LoggerNet must match the radio’s RS-

232 baud rate.

3.2.4 Step 4 – Connect

You are now ready to connect to your datalogger using the LoggerNet Connect

screen. After you connect, notice the flashing of the green LEDs on both

radios. This indicates that RF packets with the same hopping sequence are

being received by the radios. The red LEDs light solid while the connection

lasts. When you Disconnect, the red LEDs remain on for five seconds, which

is the default setting of the “Time of Inactivity to Sleep.”

Datalogger program transfer and data collection are now possible. Refer to

Appendix H for a treatment of communication distance vs. factors in the RF

path.
