Optec USB to Serial Cable, 25'

Recent advancements in USB-to-Serial converter technologies has allowed Optec to offer a single Serial / USB cable in place of the 3-piece configuration.  These cables are available in standard lengths of 6, 12, 25, and 50-ft.  Because the cable is standard RS-232 level on the long side of the cable, the 5-meter (16-ft.) length restriction for USB does not apply.
