ADAM-4550 User's Manual
1. Introduction
ADAM-4550 is an economical, wireless RS-232/
485 converter designed to interface any bidirec-
tional RS-485 device with a control center host
computer. The ADAM-4550 can be used in data
acquisition where data sensors are inaccessi-
ble to the host computer due to wiring difficul-
ties or long distances that make wiring impracti-
cal or impossible.

1.1 Built-in Intelligence
The ADAM-4550 is equipped with an on-board
microprocessor and a radio-frequency (RF)
module that can be used to interface one host
computer with multiple RS-485 networks. Each
RS-485 network can be used to support numer-
ous data acquisition devices.
