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.
