Not quite. You should also turn RTS on (pin 7).

Also, check with a scope/multimeter that 'ON' means 'positive volts' on those 
pins...perhaps they should both be 'OFF' :-)

PS: Some Icom rigs operate the CI-V interface factory-default in 'transceive' 
mode...meaning that the rig fires off QRG info when you touch the dial. Maybe 
your rig does this, which is why you get collisions on the CI-V bus when 
Hamlib polls the rig. 'transceive mode' can probably be turned off in a menu 
somewhere.
