Know before you buy
A null modem cable is designed to connect two DTE devices—such as two computers or a computer and a serial peripheral—directly to each other. It achieves this by crossing the transmit and receive lines, whereas a standard straight-through cable is intended to connect a DTE device to a DCE device, like a modem.
Yes. This cable is CMG-rated, which means it meets the safety standards required for in-wall installations. It is a great choice if you are looking to keep your workspace clean by routing cables behind drywall.
The low-profile design is specifically engineered for tight spaces where standard, bulky connectors might not fit. The molded ends are compact, making them ideal for high-density setups or equipment with recessed ports.
No tools are required. The cable features integrated thumbscrews on both the male and female ends, allowing you to tighten the connection securely by hand to prevent accidental disconnection.
Yes, it is compatible with any standard DB-9 serial interface. Just ensure that your specific application requires a null modem configuration, as this cable will not function as a straight-through extension cable.
