Description

StarTech IC232485S Serial Signal Converter

Overview

The StarTech IC232485S is a versatile serial signal converter designed to bridge RS232 data interfaces with RS485 or RS422 communication protocols. This unit is essential for integrating legacy RS232 devices into modern industrial control systems or extending serial communication distances. Its wall-mountable form factor makes it suitable for fixed installations in control cabinets or on factory floors, ensuring reliable data transmission up to 1200 meters. The IC232485S model supports data rates up to 921.6 Kbps, providing ample bandwidth for most serial data streams.

Compatibility

This converter is compatible with any system utilizing RS232, RS485, or RS422 serial communication standards. It is commonly deployed with industrial automation equipment, SCADA systems, security cameras requiring serial control, and point-of-sale (POS) systems that rely on serial data interfaces. It functions as a transparent bridge, requiring no specific driver installation on the host system beyond standard serial port configuration.

Installation Notes

The unit requires a 100-240V AC input, which is converted to 5V DC via the included power adapter (5V DC, 1A output). The converter itself is designed for wall mounting, with mounting holes integrated into its chassis. LED indicators for Power, Tx (Transmit), and Rx (Receive) provide visual feedback on data activity and device status. The operating temperature range is 0°C to 50°C (32°F to 122°F), suitable for most indoor environments. For extended cable runs, ensure the connected RS485/RS422 devices also support the maximum 1200m (4000ft) cable length.
