PureLink PureTools RS-232 Serial Control Cable, Phoenix 3-pin to DB9 Male, 1m, Switchable Pinout, Black

In professional AV racks and automation cabinets, installers often need a reliable serial link between a control processor and a display, switcher, or projector. The PureLink PureTools PTM-RS100 answers that need with a robust RS-232 cable that bridges a Phoenix 3-pin terminal block to a DB9 male connector. Its switchable pinout makes it adaptable to different equipment wiring schemes, eliminating the guesswork during commissioning.

Why choose it

The PTM-RS100 stands out for its flexibility. The 3-pin Phoenix connector accepts bare wires from control systems, while the DIP switch allows you to reconfigure the pin mapping on the fly. This means one cable can serve multiple device types, reducing inventory and simplifying service calls. The shielded copper conductors ensure clean signal transmission even in electrically noisy environments.

Ideal use cases

• Connecting a control system (e.g., Crestron, AMX) to a projector or flat panel with RS-232.
• Linking a media server to a video switcher for automation.
• Integrating legacy RS-232 devices into modern AV-over-IP setups.
• Field service kits where different pinouts are encountered.

Good to know

This cable is part of the PureTools accessory line, designed for professional integration. The Phoenix connector is a 3-pole screw terminal, so no soldering is required—just strip, insert, and tighten. The DB9 male end fits standard serial ports on most AV equipment. Always verify the pinout configuration against your device manual before powering on.
