Hi All
I have been doing allot of research on this problem and unable to find a answer.
I have run into a hole here.
My problem is that I am using the Pronto TSU9600 with the RFX9600.
I am using the RS232 for the Yamaha RX-V2700 for controls.
Yes I have made up the serial cable with terminals 2 to 3 and 3 to 2 and 5 to 5 with 7 & 8 shorted out at the AV side.
All works well except I can't turn the unit On.
If the unit is turned on manually and I push a button on the remote the function then works. It show on the amp power on but when in the off state I can't turn it on.
I have tried a 0.50sec delay but with no success.
Hex code that that is being used is 02 30 37 41 31 44 03.
Any help will be much appreciated.

Rob
