Go shielded if you can. (I'm an Industrial Electrician who's worked with both of these PLCs.) **Q: Is this a crossover cable or straight thru?** A: Your question is more inline with a Cat-5 cable, not a null modem cable. **Q: Are the wires stranded or solid?** A: The wires in SCNM9FF are stranded. Matt, StarTech.com Support **Q: You didn't answer the question on handshaking. Does it support full handshaking, partial handshaking, loopback handshaking or no hardware handshaking?** A: We apologize if we missed part of a previous question. The SCNM9FF is a simple Null Modem cable with all 9-pins connected through the cable. While it doesn't actively participate in handshaking of any kind due to there not being a chip in the cable, as long as both of your devices support the same protocols there should be no problems using whatever hand-shaking you need.

Tried different same type cables and did not work! ### ⭐⭐⭐⭐⭐ Correct null modem cable, but not fully wired. *by C***H on June 23, 2024* I bought this so one PC-based device could control another via serial port (yup, welcome to the 1990's!). It worked for this low-tech application. By my measurement here is the pin wiring. Pins 1, 5, and 9 are wired straight through. Pin 6 is open circuit. Pins 2 and 3 are cross-wired, as are pins 7 and 8. Who knows why the seller description blabs on and on about HDMI and display port. This cable has nothing to do with video! ## Frequently Bought Together - StarTech.com 10' RS232 Serial Null Modem Cable - Null modem cable - DB-9 (F) to DB-9 (F) - 10 ft (SCNM9FF) - OIKWAN USB to RS232, USB Serial Adapter with FTDI Chipset,USB 2.0 to Male DB9 Serial Cable for Windows 11,10, 8, 7, Vista, XP, 2000, Linux and Mac OS(6ft)… - StarTech.com 3m Black Straight Through DB9 RS232 Serial Cable - DB9 RS232 Serial Extension Cable - Male to Female Cable (MXT1003MBK), 10 ft / 3m --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://grenada.desertcart.com/products/436933-startech-com-10-rs232-serial-null-modem-cable-null-modem](https://grenada.desertcart.com/products/436933-startech-com-10-rs232-serial-null-modem-cable-null-modem) --- *Product available on Desertcart Grenada* *Store origin: GD* *Last updated: 2026-10-21*
