Two-Port USB Serial Adapter

The ICUSB2324852 is a USB 2.0 converter that provides two DB-9 male ports for RS-232, RS-422 and RS-485 devices. It uses an FTDI chipset and supports COM port retention so settings persist across reboots. The unit is wall-mountable and draws power from the USB bus.

Industrial and Legacy Equipment Integration

Engineers maintaining factory automation, building-management or laboratory instruments will appreciate the 921.6Kbps maximum baud rate and broad protocol coverage. Buyers who require more than two serial connections or need isolation, surge protection or a different connector type should consider other solutions.

921.6Kbps Maximum Baud Rate

The adapter sustains up to 921.6Kbps across its two ports, which determines whether timing-sensitive equipment will communicate reliably. Verify that your serial devices operate within this limit before purchase.

Questions about this item

What mounting options does the wall-mountable ICUSB2324852 adapter provide for installation?

The ICUSB2324852 is designed as a wall-mountable unit, allowing it to be secured to a flat surface for permanent installation in industrial or office environments.

How is the ICUSB2324852 connected to the host computer and what driver step is required?

Connect the USB 2.0 Type B female port to the computer using a USB cable, then install the FTDI driver so the operating system creates the virtual COM ports for the two DB-9 male connectors.

What operating temperature range should be maintained for the ICUSB2324852 to avoid early replacement?

Keep the adapter between 0°C and 55°C (32°F to 131°F) during operation; exceeding this range can shorten the lifespan of the internal bridge and serial transceiver components.
