ADAM-4550 User's Manual 13 2.8 Antenna Installation Indoor communication distance is about 300 to 550 ft. using a standard 2 dB antenna. Howev- er, actual distance depends on environmental conditions as well as antenna type and position- ing. Longer communication distances can be achieved by using an antenna with a higher gain.
14 ADAM-4550 User's Manual 3. Using ADAM-4550 Connect one ADAM-4550 to the controlling PC’s serial port with the RS-232 cable. Connect re- mote ADAM-4550 units to remote data units through the RS-485 bus. Configure each ADAM-4550 unit by following the procedures in section A.
