2.2 Installing the RTU
The following restrictions apply:
• In general, the typical “line-of sight” distance the RTU can cover is 10 km
(6 miles). This is valid if both the RTU’s antenna and its partner device are
mounted about 3m (9ft.) above the ground; the results may vary under
different conditions, and you can sometimes achieve greater distances.
• As with all wireless communication devices, the higher the antenna is, the
better the communication will be.
• All addNODE devices accept the standard Adcon sensors; however, the
connectors are different from the A730MD and A73x series. Cage-clamp
connectors are now used.
