  • 128-byte transmit and 384-byte receive buffers reduce data loss
  • 3 kg steel chassis withstands rack and bench use

8-port USB to RS-232 hub

The Black Box Corporation IC1023A adds eight serial ports through a single USB connection. It uses high-speed UARTs with 128-byte transmit FIFOs and 384-byte receive FIFOs. Data rates reach 460 kbps for RS-232 and 921 kbps for RS-422/485. The unit weighs 2.3 and is supplied new.

Industrial and legacy device integrators

This hub suits engineers connecting multiple RS-232 instruments to modern PCs lacking native COM ports. It is not for users who need internal PCIe serial cards or fibre-channel connectivity. Buyers requiring more than eight simultaneous ports should look at a different solution.

External USB peripheral for rack or bench

The device connects to any standard USB host port and draws power from the bus. It frees internal expansion slots and avoids opening the chassis. No extra drivers beyond the OS serial stack are required for basic operation. Mounting options suit desktop or rack environments.

Questions about this item

What type of USB port does my computer need for the IC1023A to work?

The hub connects through a standard USB port on your computer to provide eight RS-232 serial ports.

Will my existing RS-232 equipment work with the 460 kbps data rate of this hub?

Yes, the hub supports RS-232 speeds up to 460 kbps, compatible with standard serial devices.

How can I verify the hub is transmitting data correctly after installation?

The high-speed UARTs use 128-byte transmit and 384-byte receive FIFO buffers to maintain data integrity at up to 460 kbps.
