I just purchased a Onkyo Home Theater System HT-SP904 with a HT-R557 receiver and a RC-681M remote control. I can not get it to control the Dish 811 satellite receiver. I tried all the codes that were listed plus all the codes listed for Echostar but none of them work. Contacted Onkyo but they said to try to find out from Dish what the control code is. The Onkyo remote is expecting to see a four digit control code. Does anybody know the control code to make this combination work?
