I've run RS-422 over 150 feet using belden audio cable without issue. IIRC the main difference between RS232 and RS422 is voltage. I may be mis remembering this so please correct me if I'm wrong on that. I don't know if RS232 is harder to run long distances than RS422.

Subject: Re: [Avid-L2] Deck Control IssuesWhat's the total distance for the 9pin?On Sep 4, 2018, at 6:21 PM, avid@... [Avid-L2] <Avid-L2@yahoogroups..com> wrote:
Recently I helped a customer move their machine room and edit systems. It all went well, except for one system which will not do deck control – although it did before the move.
I've hooked up dozens of these over the years but I am stumped.
System is a Win7 HPz440 running Media Composer 8.4.something. I have tried 3 different USB to Serial adapters, 2 Rosetta Stone cables, temp cabling to the machine room and bypassing the machine control patch panel. I am also into a USB2 port since I have found they don't work on USB3.
So probably not hardware.
On the software side I have uninstalled and reinstalled the Keyspan software, confirming it is the same version that other working systems are using. I have also confirmed the same firmware. I have tried various virtual ports, allocated in the Keyspan software.
Any thoughts, suggestions, ideas appreciated.
