Overview

Thoroughly and accurately test your RS-232 (serial) cables and devices pin-by-pin with this RS-232 link tester, with LED lights.

Operating multiple devices via DB9 port can be a frustrating, even daunting task. Adapting legacy ports and technologies to a top of the line modern computer can generate compatibility errors, hardware hiccoughs, and software glitches. When an RS232 device isn’t working how do you know where the problem is? Is it not talking to the computer? Is there no signal being sent or received? Or could it be something as simple as the flow control being on the wrong setting? Wonder no more!

With the Sewell RS232 link tester you gain invaluable information when troubleshooting your DB9 ports and connected devices. With a simple, intuitive display that lights up to show which pins are sending or receiving data you will always know just what is going on with your hardware. Instillation is as simple as plugging the tester in inline with your device and looking at the LEDs on the face. With hardware screws to secure the unit in place it makes a perfect addition, either permanently or temporarily, to any RS232 link.
