1.5ft Velocity™ DB9 Female to 3.5mm Male Adapter Cable

Adapt your 3.5mm stereo jack for RS-232 serial control
(1) DB9 Female
(1) 3.5mm Stereo Male

Product Description

Why run all new cables for RS-232 control of your audio/video system, when you can use this easy adapter? The Velocity RS-232 adapter leverages your DB9 or 3.5mm stereo audio cable to run 3-conductor RS-232 control signals between your control unit and your video display. Fully molded DB9 and 3.5mm connectors provide excellent strain relief. This adapter is ideal for use with computers, projectors, and any control unit/display requiring 3-conductor RS-232 serial control.

Please Note: Not all serial control methods are supported by this adapter. This product is intended only for use with 3-wire RS-232 control cables with common ground (pin 5), transmit data (pin 3), and receive data (pin 2). For the exact pinout of your audio/video equipment, please contact your RapidRun sales representative for assistance, or call customer service at 1-800-506-9607.

Comments about C2G 1.5ft Velocity™ DB9 Female to 3.5mm Male Adapter Cable:

Is cheap, readily available (generally - B/O until 4/15/14 now, ridiculous) substitute for Samsung OEM cable of this style.

Requires null modem adapter when used with standard RTI DB9-RJ45 adapters.

Needs to be offered in right-angle 3.5mm plug version for when TVs are close to the wall, which is almost always.

  • Business

  • Q:

    Is this a strait through pinout or null modem?

      This cable is not considered straight through or null modem. Please see the pinout at the bottom of the webpage. I would contact the device manufacturer to confirm the proper pinout.
