Dear Mike, thanks for the reply,
after retyping more time all the parameters, the CI-V is working now, I can not say what was the wrong data. Just a remark, the USB socket matallic shield (control side) was not welded to the board. It allow the socket to move making  difficult to insert the plug. Of course after welding, all is ok now.
Regarding the PTT, I use an interface connected to the USB port. The interface has the CAT and CW output as well as a PTT contact to switch the transceiver to TX when I transmit CW. If I connect the interface PTT contact to the transceiver, it switch normally but the transceiver is getting silent during transmission. In other words, I can not hear what I am transmitting. It does not happen if I use the Breack-in, without driving the PTT.
It seems that if I short the pins 2 and 3 on the DATA PACKET (on the back of the transceiver) I can transmit and hear the tone while transmitting (I made just a quick test).
My intention is to use the RTS fron CAT the serial port (pin 7) to drive the above pins 2 - 3. I hope it is possible through COM 2.
Any simpler idea?
Thanks for the support,

Sorry to bother you all guys but I still having problems with my IC706MKIIG.
I tried to connect COM2 to the radio CI-V plug through a interface (using MAX232) but it does not work. The port configuration has been done as per the Mike's post. In addition the data connection seems to get very slow, turning the VFO there is a delay in the frequency change.
Of course the inetrface is working properly when I connect the radio to the PC withour remoterig. It mean the interface and cables are OK.

Abour the monitor problem I mean when I transmit CW using the BREAK IN, I can hear the note in my headphone. The note disappear if the PTT is driven by a external contact or pushing the PTT on the mike. The PTT driven by external contact is very helpful in case you are using a linear amplifier to avoid arches etc. I hope to be clear enough.

Thanks for the support,

Dear Simon, thanks again for the reply, I will wait Mike is back from his holiday. In the while I realized that, working CW, when I drive the PTT by a PC interface (it happen even if I push the PTT mike) the CW monitor signal (radio side headphone) disappear. Working semi BK the monitor is OK. I miss something?

Hi,

I'm not an expert, but looks like you are mixing up two operating modes: Standalone IC-706 with detached front panel and ICOM CI-V generic mode, or are you trying to controll the IC-706 only via CI-V?

vy 73, Simon

Hi Simon, thanks for the reply.
As per my experience by using the IC-706 connected to the PC directly (without the remoterig stuff) I can operate on the radio panel and on the PC in the same time. It means the 706 panel is working as usual and some funcion can be operated also from the PC. I have experieced that even using other radios and the N1MM software (which is dedicated for contest).
It seems that once I connect the TTL plug, the power to the front panel shut off.

If I try to connect the radio side CI-V jack to the TTL port using the cable as per the schematic, the Icom 706 front panel is getting dark, seems there is not power.
Any idea?
Thanks, I1HJT
