RS-485 converter / RS-232

Application

Most industrial computer systems come with standard
RS-232 serial ports. Though widely accepted, RS-232
has limited transmission speed, range, and networking
capabilities. The RS-422 and RS-485 standards
overcome those limitations by using differential voltage
lines for data and control signals. The BSC3123i
converter lets you to take advantage of RS-422 and
RS-485 on systems originally equipped with RS-232.
They transparently convert RS-232 signals to RS-422
or RS-485 signals. You do not need to change your
PC's hardware or your software. The BSC3123i lets
you easily build an industrial grade, long distance
communication system with standard PC hardware.
They extend the communication distance by 1.2km
(4kft) or increase the maximum number of connected
nodes by 32. The BSC3123i also provides the optical
isolation for system protection.

Features

Polarity guard that prevents damage from reverse power
connection and over voltage protection

(TX/RX) and operation modes (RS-422/485 4W or RS-485 2W)
Clear indications of all signals on the casing allow easy and proper
connection
Plug-in screw terminal blocks for easy RS-422/485 and power
supply wiring
