Will this work with slc 500 processor?

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.)

Is this a crossover cable or straight thru?

Your question is more inline with a Cat-5 cable, not a null modem cable.

Are the wires stranded or solid?

The wires in SCNM9FF are stranded. Matt, StarTech.com Support

You didn't answer the question on handshaking. Does it support full handshaking, partial handshaking, loopback handshaking or no hardware handshaking?

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.
