Black Box IC1477A-M RS232 RS485 DB25 Converter

Black Box IC1477A-M is a compact DB-25 data transfer adapter that bridges RS-232 and RS-485 serial signaling, allowing an RS-232 host to communicate with RS-485 devices over standard 25-pin connectors in industrial environments. It provides a DB-25 male RS-232 connector on the host side and a DB-25 female RS-485 connector on the network side, enabling reliable, pin-for-pin serial connections for data acquisition, control, or instrumentation workflows that require RS-485’s longer reach. Available as IC1477A-M and IC1477A-M-US, the unit is CE-certified and backed by a 1-year warranty; BarcodesInc and other Black Box resellers list it as a DB-25 Data Transfer Adapter suitable for linking legacy RS-232 equipment—such as PCs, barcode readers, or instrumentation—to RS-485 networks. Catalog listings consistently describe IC1477A-M with one DB-25 male RS-232 connector and one DB-25 female RS-485 connector, ensuring compatibility with standard 25-pin interfaces and reducing the need for additional adapters in configured network topologies.
