nytetyme1976 Posted April 2, 2014 Posted April 2, 2014 OK, so I want my 994 to be near the TV so I can use the IR features but the only outlet nearby has two battery backups on it with tons of noise. If I had a great quality Cat-6 cable what is the MAX length I can run it to my PLM? Ideally it would be 50' or so for me to go back to my breaker panel outlet. Thoughts?
SteveL Posted April 2, 2014 Posted April 2, 2014 nytetyme1976, A 50' should be able to work for the PLM cable. This only comes from some applications where I have installed it on a 50" cable for trade shows. The spec on it is a little different. It is suggested a 10' max and 6' is recommend for the product.
gatchel Posted April 2, 2014 Posted April 2, 2014 Isn't the data RS-232 for comms to the PLM? If it is you could try using converters at each end if the long cable doesn't work. If you convert the data to RS422 4 wire you will get better reliability with RS422 as it is a balanced communication with has noise rejection properties when using twisted pair cabling. I can elaborate if you like. This is all in theory, of course, I haven't tested it personally.
ISYhbsh01 Posted April 2, 2014 Posted April 2, 2014 Or consider using instead an IR extender. Sent from my SPH-D710 using Tapatalk
nytetyme1976 Posted April 3, 2014 Author Posted April 3, 2014 I believe that you are correct it is labeled RS-232 but it still uses a plain old Cat-5e cable to transmit that signal over. Anyway thanks for the help, I did extend the cable and now things are working PERFECTLY! Robert

MikeD Posted April 4, 2014 Posted April 4, 2014 Or you could plug your PLM into the battery backup since it is dual-band. I run my PLM on a UPS and rely solely on its dual-band capabilities (an access point or another dual-band device close by) for communications. Only drawback I know of is you loose X-10 communications if you still use those devices since the X-10 signals only ride on house wiring. Not sure if there are other issues with systems such as ELK since I do not have one. ~Mike
