Null Modem Cable

Null Modem Cable - The Original Networking Cable

Our fully molded D-Sub null modem cables offer solid performance at economical prices. Null modem cables permit two serial (RS-232) "DTE" devices to communicate with each other without modems or other devices (DCE's) between them.

A Simple "Legacy" Solution

The Null modem cable allows the TD and RD signals from both devices to communicate with each other. This was one of the earliest methods used to network two computers and is still used today.

All null modem cables include foil shield construction, molded hoods and a PVC jacket for flexibility and durability.
