Null Modem Cables & Adapters
Shop null modem cables and adapters for connecting compatible RS232 serial devices directly without a modem. Industrial Netware offers null modem connectivity products from trusted manufacturers, including QVS, for industrial equipment, control systems, legacy computers, and serial communication applications.
Explore DB9 female-to-female null modem cables, crossover serial cables, and compatible null modem adapters. Null modem connections use crossed signal wiring to support communication between compatible serial devices.
Review individual product specifications for connector gender, pinout, handshaking configuration, and cable length. Null modem wiring arrangements vary, and a straight-through serial cable cannot always substitute for a null modem cable.
