Is it possible to run multiple RS-232 lines within the same 35-wire cable. I am concerned about crosstalk and parasitic capacitance. The cable would be approx. 30' max. I have to talk to set of 10 different instruments across the room and I don't want to run 10 bulky cables. Wireless is not an option due to cost. Thanks to anyone who can reassure me that I won't be seeing garbage on the PC end!
