#160584 - with PLC or rs-485 Responding to: ???'s previous message |
Hai...
Agree with all used PLC at powerline. Is that slave only one? If yes,how's about with repeater rs-485? Something like this.. 800m----repeater(2 MAX1480 and 1 TTL)---800m---repeater(2 max1480 and 1 TTL)--until 10km.. I never tried but Makarand could tried it.. The only problem is delay time between repeaters. Thank's Jeckson Ben |
