The ADAM-4521 is an intelligent RS-422/485 to RS-232 converter
specifically designed to connect RS-422/485 devices to an RS-232
network. RS-232 is the most common transmission standard. Although
widely available on most computer systems, measurement equipment, PLCs,
and industrial devices, its transmission speed, communication distance,
and especially networking capability are limited due to unbalanced
transmission. The ADAM-4521 addressable converter solves this problem
and lets you easily build up an RS-485 network with your RS-232 devices
by assigning each one an address for easier communication.
