Product Details

The B&B Electronics BB2171 is a compact, self-powered RS-232 to RS-485/RS-422 serial interface converter designed to extend the range of serial communications and connect RS-232 devices to RS-485 or RS-422 networks. Powered directly from the RS-232 control lines, it requires no external power supply for most standard applications.

Key Features:

  • Converts RS-232 signals to RS-485 (2-wire) or RS-422 (4-wire) for long-distance serial communication
  • Self-powered via RS-232 RTS/DTR control lines — no external power adapter required in most setups
  • Supports data rates up to 115.2 Kbps
  • DB9 male RS-232 interface connector for easy connection to PC serial ports
  • Compact, standalone inline form factor for simple point-to-point or multi-drop wiring
  • Automatic or manual transmit data (TD) enable control for RS-485 half-duplex operation
  • Supports cable runs up to 4,000 feet (1,200 meters) on the RS-485/RS-422 side

The BB2171 is ideal for industrial automation, building controls, data acquisition systems, and any application requiring reliable long-distance serial communication. Its plug-and-play design makes installation straightforward without the need for drivers or software configuration.

Awesome! Cheapest prices on the products I have needed!

Easy to follow and find what I needed.

Is this white or black?

please don't show price on packing slip

it was easy to find exactly what i needed, good price and easy check out. Fast delivery. I'll be a repeat customer.

Great!

I saved over a hundred$ on a set of electric cooling fans. so the prices r great but it took 4 days to process and ship my order so well see how long it takes to get here but overall I would rather save money than get fast shipping

so far so good

Expected delivery was not listed prior to purchase

1st order with Autoplicity. Very easy and very fast shipping. Highly recommended.
