Product information
DB9-M-RJ45-NULL
Overview
Speed up and simplify RS-232 integrations by using the Binary DB9-M-RJ45-NULL adapter. This pro cable adapter converts a DB9 male serial connection to an RJ45 modular jack with a Null Modem pinout, letting you run custom Cat5e/6 cable lengths instead of bulky, fixed serial leads. The result: cleaner installs, fewer terminations, and faster troubleshooting for control systems, access control, and CCTV deployments.
As a Binary pro cable adapter, it supports standard RS-232 signaling while removing the need for soldering or custom DB9 harnesses. Compatibility with Cat5e/6 cabling reduces material costs and simplifies inventory for integrators installing security, surveillance, and building automation equipment. The adapter's null modem wiring is preconfigured for device-to-device communication, so installers can focus on system commissioning rather than pin mapping.
Backed by Binary’s Lifetime Limited Warranty, this DB9-to-RJ45 adapter is ideal for monitoring, control, and security installations that demand reliable serial connectivity. Add the DB9-M-RJ45-NULL to your toolkit for cleaner, faster RS-232 deployments — perfect for surveillance camera controllers, access panels, and legacy device integration.
