#123907 - Best 485 Cable In Industrial Environment |
Dear Peoples,
1) For a long 485(Half Duplex) Network (with around 150-200 node)and a distance of 4000 feet,Can I use a 4 core shilded ("SAXTON data Cable") 24 AWG cable, But it is not twisted, However all 4 cores are twisted themselve in package.Cable have sheild. Or do you recommend me some other cable in CAT5 - CAT 6...UTP/STP Like 8 core UTP (24AWG) Or 8 core STP (24AWG) 2) If I use 4 pair Twisted pair cable th only two pair is sufficient for Data and Ground.Can I use one un-used pair for 18-24 volt supply for MicroContoller. On each node, a 7805 is being used for DC to DC conversion.So Can I use the any pair for DC supply.The maximum Distance between two node is 100 Feet. Recommend me Please, Thanks MOIZI |

| Additional hint... | 01/01/70 00:00 | |
the slew rate limit is nice, but even better | 01/01/70 00:00 | |
| i think stubs and termination will be more of a | 01/01/70 00:00 |
