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.
