1. Does it need to be an FTDI chipset or will a prolific work.
2. I plug into the radio USB port correct?
3. Do I need to set up any comm courts in cat
1. Yes. FTDI chipset only. Be careful of knock off Chinese cables found on Amazon as some are not real FTDI chipsets and will not work. DigiKey and Mouser have the real deal. Reason they chose FTDI is the cable chipset has a unique serial number for each cable. That way it can maintain same "port number" within the radio.
2. Plug into the USB port on back of radio. If plugging in more than two devices into radio (FTDI cables or D-Star dongle) you can use a USB hub.
3. In SmartSDR click on settings and USB cables. You will see new CAT Cable, serial number of the cable, and Type. It will initially show invalid. Double click it to open the config menu for the cable. If you click on advance it bring up extra options such as baud rate, parity, and flow control
Here's screenshots of a cable set for serial CAT control. There are different functions it can track for CAT info. For an amplifier I use TX Slice.

BTW I am using an FTDI USB2-F-1001-X10 cable purchased direct from FTDI
This will work fine as long as you are emulating a legacy radio by only having Slice A and Slice B active.
I assum you are using the latest software release. Are you plugged into radio? What cables are you using did you make any modifications to pin out
This config runs well since 6 month here. One RS232 cable from Amp true a RS232/USB adapter and plugged into PC USB slot. I never operate without PC; so it's equal where the Amp is connected. I never try the USB at Flex (will give a try). Have a second 3500A, also direct connect to my IC7800.
Yes, it's a new software inside OM-P (only a PIC to change, easy - ask Tibi :-)
(... both PA usable via WAN for remote operation; here placed at basement - not in shack)
When the 'transmit trigger' is set to 'TX slice', the radio should put out the TX freq on Kenwood VFO A or B. The OM4000 sequence goes FT, FA or FT, FB depending on the radio responding FT0 or FT1 if the radio responds FT0 the OM power will respond FA if the radio puts out the freq in response to ether VFO A or VFO B the PA will have the correct frequency. All quite simple and consistent with the Kenwood protocol except for the small bit of logic causing smartSDR TX trigger to ALWAYS output the freq on one of the 2 Kenwood VFOs depending on the FT response being 0 or 1. That is what TX trigger if for!
If you don't use more than 2 slices it will work when they fix the FT command in the next release as Tim said. This is NOT a Flex issue but a limitation of the Kenwood CAT command structure.
If you have the cable set for TX slice and have auto poll enabled it should send the freq info to the amp upon freq or band change. That should have the amp see the CAT command, adjust, but will time out again. At least the amp will be tuned though. A workaround until the next release.
From page 22 of the SmartSDR CAT manual
FT Reads / Sets Transmit VFO (0=A, 1=B)
If the radio is set to TX on VFO C or higher SmartSDR CAT defaults to sending an FA command. The Kenwood FT and FA/FB commands were only designed for two VFO radios. The 6500 and 6700 can have 4 and 8 receivers respectively. Any one of those receive slices can be designated the TX slice. If the TX slice is C or higher then the radio will return FT0 and FAxxxxx for the active slice and frequency. The amp should still work and not disconnect but the amp will think the radio is set to TX on slice A instead of the actual TX slice (if C or higher).
As Tim stated the FT command is not working with the USB cable in the 1.10.8 public release but should be fixed in the next public release
