StarTech 4 Port Native ExpressCard RS232 Serial Adapter Card with 16C950 UART StarTech 4 Port Native ExpressCard RS232 Serial Adapter Card with 16C950 UART

The EC4S952 4-Port ExpressCard-based Serial Card lets you add four RS232 serial ports to your laptop or ExpressCard equipped desktop computer, using an available ExpressCard slot.

Compatible with ExpressCard 34mm and ExpressCard 54mm card slots, the 4 Port Serial ExpressCard includes a slot spacer for greater stability while installed in 54mm slots.

Backed by a StarTech.com 1 year warranty and free lifetime technical support.
