## Questions & Answers

**Q: Will this work with slc 500 processor?**
A: Any null modem cable with at least simple handshaking (TX/RX crossed) will work with the SLC 500 and ML1400 over DF-1 protocol.  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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Cable worked fine.
*by J***R on September 7, 2025*

Worked on an older device that I needed a longer cable for. Also purchased some gender changing adapters for the same device. All worked flawlessly.

### ⭐⭐⭐⭐⭐ Great cable, saved my bacon!
*by R***S on March 3, 2025*

I used this in conjunction with Norton Commander for DOS to back up data from a vintage PC that didn't have a working disk drive. It worked great and got me out of a pinch!

### ⭐⭐⭐⭐⭐ 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!
