Black Box IC1474A-F RS-232 to RS-422 transceiver

SKU CH-NN9G-6JT0P MPN IC1474A-F

Converts RS-232 to RS-422 with internal power for 115.2-kbps links up to 4000 ft

  • Product typeTransceiver
  • Maximum range4000 ft (1,219 m)
  • Power adapterInternal
  • Converts RS-232 to RS-422 for long-distance serial links
  • Extends data signals up to 4000 ft (1219.2 m)
  • Delivers 115.2-kbps throughput over extended runs
  • Internal power supply removes need for external adapter
  • Terminal-block RS-422 interface suits industrial wiring standards

What it does and who it fits

The Black Box IC1474A-F converts a single RS-232 DB-9 port to an RS-422 terminal-block connection using an internal power adapter. It serves installers who must bridge legacy serial equipment to differential RS-422 lines in commercial or broadcast environments.

Who should consider another option

This unit provides one DB-9 RS-232 interface and one RS-422 terminal block, so it cannot link two RS-232 endpoints directly. Buyers who need dual RS-232 conversion or a second DB-9 port should select a different converter.

Distance and speed that define the link

The transceiver delivers 115.2-kbps throughput over copper pairs up to 4000 feet or 1219.2 metres, matching the SMPTE-compatible pin-out specified for video control gear.

Questions about this item

Should I buy one IC1474A-F or two for my RS-232 devices?

Use one converter if the peripheral already runs on RS-422; use two if both ends only speak RS-232.

What throughput does the 115.2-kbps rating deliver over a 4000-ft link?

The link sustains 115.2 kbps across the full 4000 ft (1219.2 m) distance.

How does the DB-9 RS-232 port connect to the RS-422 terminal block?

The unit converts bidirectionally between the single DB-9 RS-232 interface and the RS-422 terminal block.
