USB - to - Serial adapters

If you need a USB - to - Serial adapter, be aware that so many just didn't work that we were forced to sell the one that did. (Many work on and off, but will drive you crazy when you need to rely on them. )

S-US232B-EC is the economy version adapter without cable Windows recognizes this as a serial Com port and requires no IRQ, DMA, or I/O port resources. Features the full set of RS-232 modem data and control signals (TxD, RxD, RTS, CTS, DSR, DTR, DCD, RI, and GND) with a DB9 male  serial port connector.

For a dual port version see S-USB-2COM
