A server in a manufacturing environment needs to receive input from multiple measurement devices on the production line. Which of the following would be needed on the server?

An HBA (Host Bus Adapter) card is used for connecting to storage devices, typically Fibre Channel or SAS/SATA, not for general measurement device input.

A SCSI (Small Computer System Interface) card is an older type of HBA used for connecting to SCSI storage devices, which is not relevant for connecting industrial measurement devices.

Many industrial and measurement devices, especially older or specialized ones, communicate using serial protocols like RS-232, RS-422, or RS-485. A serial card (also known as a serial port expansion card) provides these physical ports (e.g., DB-9 or DB-25) on the server, allowing it to connect to and receive data from multiple such devices simultaneously.

A video card provides graphical output to a display and is not used for receiving input from external measurement devices.
