(/thread-4699.html)

- Wimphot - 06-14-2017 [size=\"3\"]Q1/. On reading the instructions for my newly acquired UCM/USB: Page 5 of ucmman state \"...up to 100 meters, use a cable with 3 twisted pairs. 12V/GND, KA/KB are to be paired with one pair as spare\" I\'d like to confirm how these connections should be made. As I read it (admittedly late at night )[/size] [size=\"3\"]12V&KA are linked - at both ends? [/size] [size=\"3\"]GND&KB are linked - at both ends? and the third pair are [/size] [size=\"3\"]A & B which are connected respectively at each end [/size] [size=\"3\"]Somehow I feel this isn\'t right and I\'d prefer to ask dim newbie question rather than \'fry\' something! Is there a pic\' somewhere that will help me. Q2/. Is there any reason why I cannot have RJ45 plugs and sockets in the line, this will allow me to extend a redundant cat5e cable already under the floor which at the moment does not quite reach. The total run between the UCM and Comfort will be no more than 8 meters. Thank you [/size] - slychiu - 06-14-2017 12V and GND should be paired and KA/KB should be paired, and connected at both ends the spare pair need not be connected There should be no problem in using RJ45 plugs and sockets If your UCM/USB is extended to 8 meters to connect to your computer, it may be more convenient to use UCM/ETH03 conencted to your network so your computer with wifi esepcailly a laptop can access from anywhere. If you have a fixed desktop, then USB may be better
