Industrial RS-232 to TTL adapter

The UOTEK UT-210 converts RS-232 signals to 0-5 V TTL levels using a DB9 male to DB9 female interface. It draws power directly from the serial port so no external supply is required. Engineers and hobbyists use it to link legacy COM equipment or microcontroller boards to modern systems.

Sustained data integrity

The converter handles continuous streams at rates from 300 bps to 115.2 Kbps without handshake lines. An internal charge-pump circuit keeps the link active even when the host port is not initialised. Automatic flow-direction control prevents data collisions during long sessions.

Rugged thermal profile

The 62 mm × 34 mm × 18 mm enclosure operates from -40 to 85 °C at 5 % to 95 % relative humidity. Port-powered operation adds negligible load to the host and produces no audible noise. The compact form factor fits inside tight panels without airflow concerns.

Questions about this item

How much power does the UT-210 draw when running continuously?

The converter is port-powered over RS-232, RS-485 or RS-422, so it needs no external supply and draws its operating current directly from the serial lines.

What cables or ports must my system already provide for the UT-210 to function?

You need an available DB9 male serial port on the host side; the adapter presents a DB9 female connector for the TTL device and carries TXD, RXD and GND only.

Will the UT-210 operate alongside older RS-485 or RS-422 gear on the same bus?

Yes, it draws power from RS-485 or RS-422 lines as well as RS-232, supports 300 to 115.2 kbps and works from -40 to 85 °C.
