USB-C to DB9 serial adapter

The Interex By Tripp-Lite USA-19HS-C adapter connects a USB-C host to equipment using a DB9 serial interface. A three-foot detachable cable is included in the package. The unit weighs two ounces and fits in a pocket or bag for portable use. No external power supply is required for operation.

Suits legacy serial equipment

This adapter suits technicians and engineers who need to connect modern USB-C devices to older serial hardware such as industrial controllers or networking gear. It provides full modem control plus hardware and software flow control. Buyers whose equipment uses a different connector type or requires a longer fixed cable should look at other options.

230 Kbps maximum data rate

The adapter supports data transfer speeds up to 230 Kbps, which is double the rate of standard built-in serial ports. It also works with any USB-C cable up to 16 feet for extended reach. LEDs on the housing indicate link status and data activity. Plug-and-play operation allows immediate use without driver installation.

Questions about this item

Does the USA-19HS-C generate noticeable heat or draw extra power when left connected all day?

No external power is required and the adapter weighs only two ounces, so it runs cool and draws minimal current from the USB-C port during continuous use.

What must I already have to use this USB-C to DB9 adapter?

You need a device with a USB-C port and a serial peripheral that accepts a DB9 male connector; the three-foot detachable cable is included.

Will the adapter work reliably with legacy serial equipment that expects standard PC port speeds?

Yes, it supports data rates up to 230 Kbps, which is double the speed of a built-in PC serial port, and provides full modem control with hardware and software flow control.
