4-Port USB to RS232 DB9 Adapter

This adapter cable adds four serial RS232 DB9 ports to a system through a single USB connection. It uses an FTDI chip to provide reliable communication with legacy industrial equipment, networking gear and scientific instruments. The internal power cable form factor suits rack-mounted or embedded installations where external dongles are impractical.

Replaces single-port USB serial cables

Consolidating four connections into one device reduces cable clutter and USB port consumption on the host machine. The upgrade is worthwhile when multiple serial devices must be managed simultaneously, such as in automation cabinets or laboratory racks. It does not suit builds that need only a single serial link or require optical isolation for noise immunity.

Questions about this item

What type of connector does the 4 Port USB to Serial RS232 DB9 Adapter Cable use for each serial port?

Each serial port uses a DB9 connector, which is a 9-pin D-subminiature interface commonly used for RS232 serial communication.

Does the adapter require any internal power connection or is it powered solely through the USB interface?

The adapter draws power directly from the USB port, so no separate internal power cable or external power supply is needed for operation.
