Frequently Asked Questions
What is a null modem cable used for?
A null modem cable enables direct serial communication between two computers or between a computer and a terminal without requiring a modem. The crossed wiring configuration (RX/TX swap) allows devices to communicate as if they were connected through a modem, making it essential for legacy system integration, equipment configuration, and point-to-point data transfer.
Can I use this DB9 female cable for standard serial connections?
This cable is specifically designed as a null modem configuration with crossed wiring. For standard serial connections between a computer and a peripheral device (like a printer or scanner), you would need a straight-through serial cable instead. The null modem wiring is optimized for computer-to-computer connections.
Is the 6-foot length suitable for my installation?
The 6-foot length is ideal for most workstation and equipment rack installations, providing enough reach for typical office and industrial setups. If you need a longer connection, B+B SmartWorx offers extended lengths. For shorter distances, standard 3-foot alternatives are also available.
Why choose B+B SmartWorx for serial connectivity?
