BONAEVER

BONAEVER RS232 to RS485 / RS422 Serial Converter Adapter bag

SKU CH-B79G-68F7R

A bi-directional serial converter that adapts RS232 signals to RS485 or RS422 with automatic baud-rate detection up to 115.2 Kbps and a maximum connection distance of 4000ft (1200m)

  • Case styleProtection Case
  • Connects RS232 gear to RS485 or RS422 networks
  • No external power needed thanks to charge-pump design
  • Auto-detects baud rates up to 115.2 Kbps
  • Extends serial links up to 4000ft (1200m)
  • Mini-size adapter fits tight equipment racks

Industrial Serial Converter

The BONAEVER adapter converts an RS232 signal to RS485 or RS422 for direct COM port connectivity. It targets engineers and technicians integrating legacy serial equipment with modern industrial systems. The unit requires no external power supply, drawing energy from the serial port itself. Its mini-size form factor suits tight enclosures and field-service kits.

Sustained Communication Stability

Unique serial charge pump technology enables true three-wire operation using only TXD, RXD and GND lines. Automatic baud-rate sensing up to 115.2 Kbps removes the need for manual port initialisation. The adapter maintains reliable bi-directional data flow over distances reaching 4000ft (1200m) without signal degradation. Auto-detection of RS422 and RS485 modes simplifies deployment in mixed networks.

Maximum Reach Decides Fit

The 1200-metre range is the single specification that determines whether this converter suits the installation. Shorter runs may not justify the hardware, while longer links exceed its rated capability. Buyers needing fibre extension or wireless bridging should look elsewhere. No other distance or cable-type rating is provided.

Questions about this item

Does the RS232-to-RS485/422 converter draw extra power or generate heat when running continuously?

It uses a built-in charge pump powered from the RS232 port, so no external supply is needed and heat remains negligible during all-day operation.

What existing port or cable must I already have to use this adapter?

You need a standard DB9 RS232 COM port (TXD, RXD, GND) on the host side; the converter plugs directly into it.

Will this work with legacy RS422 or 2-wire RS485 gear I still use?

Yes — it auto-detects RS422, 2-wire and 4-wire RS485 modes and handles baud rates up to 115.2 Kbps over distances up to 4000 ft (1200 m).
