We currently have one Powermid receiver (model RE549) in the living room which controls all of our IR devices. The Powermid transmitter (model ST539) is in the dining room. I would like to add a second transmitter in the bedroom to control the DVD recorder in the living room.

1. Can two ST539 transmitters control one receiver?
IOW, is the RF transmitted only when the red led in the transmitter is blinking?

2. If item-1 is true, does anyone know if Powermid sells ST539 transmitters separately?

Any gotchas with my plan?

Thanks,
Raptor
