(1 star) not compliant

By: hsieber
Not really a compliant null modem cable. CD (pin 1) is wired straight through rather than being tied back to pin 6 (DSR). Does not work with file transfer programs that require handshaking. May work for some but total waste for me. Neither Amazon nor Startech provides any wiring diagrams (that I could readily find), had to manually buzz out.

Response from
Matt, Customer Support
We apologize that our SCNM9FF was not suitable for your specific setup. While there are a number of pinouts that can be used for null-modem cables, this cable crosses pins 2-3, 4-6, and 7-8. We are happy to provide a technical diagram with the pinout included if you contact us at Our Technical Advisors are available 24 hours a day, 5 days a week to provide assistance.

(5 stars) Super fast delivery

By: webtek
Cable is long which helps when the device is in an obscure location. Works great.
