Comtrol 4000033 DB78M to DB9M Octacable Assembly

The Comtrol 4000033 is a DB78M to DB9M octacable assembly that expands a single DB78 male connector into eight individual DB9 male connectors. This cable fanout assembly enables connection of up to eight RS-232 serial devices to a Comtrol RocketPort PCI multiport serial adapter card. The 3.5 feet cable length provides flexibility in device placement while maintaining signal integrity across all eight channels.
