I would like to avoid using an external PC with DDUTIL.
The FTDI serial port is correctly recognized and the port settings are correct, but there is no communication. Is the Kenwood protocol automatically selected when I enter CAT into the port setup menu or do I need to select the Kenwood protocol in some other menu.
I am running firmware revision 18.104.22.168 on a Flex 6600M
Thanks for any suggestions. W8GNM
this should apply even using 6600M
i dont know if there are any setting in your amp that are required
i run a KPA500
The FTDI works very well except when you kill the slice TX flag the Tokyo-Hi power goes to 160 meters.
A work around for the amplifier switching to 160m when the Tx slice is turned off is to trigger the COM port from TX ANT-1 instead of TX SLICE. This keeps the amplifier on the right band regardless of whether the TX SLICE is enabled or to which tuning knob the TX SLICE is assigned.
I’m attempting to accomplish exactly the same thing as described by W8GNM in his original post, except that I’m using a FLEX-6500 and Tokyo Hy Power (THP) HL-2.5Kfx. The 6500 software is completely up-to-date.
Unlike the THP HL-1.5Kfx which has a nine-pin serial connector on the back panel, the HL-2.5Kfx sports a 15-pin connector. The HL-2.5Kfx came with CAT cabling that allows for communication with many of its ICOM, Kenwood (15-pin to 9-pin) and Yaesu contemporaries. I have successfully implemented frequency tracking between my ICOM-7700 and the THP amp, via the THP supplied ICOM CAT cable, so the THP frequency tracking has worked in that instance.
In what may be seen as a clear demonstration as to just how much I don’t understand about serial communications, I’ve mated my FTDI serial to USB cable with the THP supplied Kenwood CAT cable (with 9-pin female-to-female adapter and with/without a null modem in series), but with no success in implementing frequency tracking between my 6500 and the THP HL-2.5Kfx. The 6500 sees the USB cable in the settings, but logs no data.
I’m using the same FTDI serial to USB cable that worked well in allowing my 6500 and Palstar AT-AUTO tuner (Kenwood protocol) to communicate, so presumably this cable is working properly.
The schematic for the THP Kenwood CAT cable is found on the bottom of page 18 of the HL-2.5Kfx manual, found here: http://www.ab4oj.com/dl/thp/hl2_5kfx/manual_hl2_5kfx_complete_schematics.pdfSo, is this cabling arrangement fundamentally unworkable as I’ve described it, or does its failure to work point to some other issue such as a defective THP supplied Kenwood CAT cable or setting error of some sort?
