Re: Kenwood TS-850 and Commander settings

Ed Douglass

Thanks, Dave.  All of your setting suggestions are what I have been using.  The serial cable is not the null modem type. There are no bent pins. 

The dual serial port is old.  The manufacturer was NetMos Technology.  In November 2012, NetMos was acquired by MosChip Semiconductor.  The driver number was NM9835S.  It could the 98 in the number is a reference to Windows 98? That old??  In February of this year, the company that is responsible and supplies drivers became ASIX Electronics.  Their driver number, MCS9835, is version  It is digitally signed by Microsoft Windows Compatibility Publisher.

Here's a thought.  This card was working in Windows 7.  I think it has not worked since I changed the motherboard and began using Windows 10, 64 bit.  Could it be that this old dual port card can no longer make it in the W10 environment?  This would fit your suspicion that I have a hardware problem and not a DXLab software issue.

Make sure

- Commander's interrogation is enabled, with an interval of 200 ms

- the serial port's RTS is set to "ON"

- the radio and Commander are set to the same baud rate

- you're using the correct "variety" of serial cable (straight-through vs. null modem)

- there are no bent pins

Otherwise, there's a hardware problem.

Thanks, Bob. Just did check the port number assignments and Device Manager tells me that this dual serial port card (now ASIX MCS9835) is assigned as ports 2 and 3. In Device Manager, set the parameters to 4800, 8, None, 2 and no flow control. The two ports were set at 9600. Also re-updated the ASIX driver for this card. No changes observed.

May be that Windows 10 assigned a different COM port number than 2. I have a USB to COM port adapter and when I installed a new driver the ports changed. So might want to check that.

The IF-232C interface being used is the LCU3-K made by W1GEE. Made for Kenwood radios. Software must assert RTS for the TTL interface to receive power. No other instructions. Plug 'n play in terms of hardware. It's the software settings that have to be right for Commander and the TS-850 to "talk".

Thanks for the help so far.

You also need to set RTS on. See <>.

sometimes you can get them to work with a baud rate of 9600 but go to commander config and select kenwood slow.

Would someone tell me the correct settings so that my Kenwood TS-850 and Commander will “communicate†with each other? Using COM2 of a dual COM port card in a PCI slot. Windows Device Manager says the drivers are up to date and the device is working. Using a W1GEE TTL device made for the TS-850 that connects between COM2 and the ACC1 port of the TS-850. This equipment has worked in the past. Got a better motherboard. Windows 10 fully updated. Haven’t found the right permutations and combinations in the Commander Config settings to make the Commander and the TS-850 “talk†to each other. (Using COM3 and another W1GEE device for PTT.) Please help! Ed
