FIGURE G-1. Short-Haul Modem to RF400 Setup
Configure RF400s for point-to-point (see Software Setup Section 5.3). Default
settings should work unless there is a neighboring network (see Section 5.3.1,
4.d).
12 V power for the base RF400 can be supplied by an AC adapter as shown or
a Field Power Cable (see Power Supplies in Section 4.4). Current dataloggers
will supply remote RF400 power via serial cable.
