StarTech 9FMNM-3M-RS232-CABLE 9.8 ft Null Modem Cable

When serial equipment still anchors the workflow, the cable has to do more than connect two ports. This 9.8 ft RS232 null modem cable is built for crossover communication between compatible devices, using DB9 male-to-female connectors to support the wiring pattern required by many legacy serial deployments. It is the right choice when a straight-through cable would fail to establish the link. The cable uses 28 AWG conductors and aluminum mylar shielding to help reduce EMI in environments with nearby power and equipment noise. Metal connector shells and nickel plating add durability at the contact points, which matters in racks, labs, and service benches where cables are moved and reconnected often. The black PVC jacket keeps the assembly flexible enough for practical routing while still holding up to everyday use. For teams maintaining modems, console access paths, or serial-connected hardware, this cable offers the dependable physical layer that keeps older systems serviceable without unnecessary complexity. Lifetime warranty coverage adds another layer of confidence for infrastructure teams that need parts they can standardize on.
