Author Topic: Kenwood TS-570D and HRD can’t communicate.  (Read 17004 times)

I bought a DB9 serial cable and hooked it up to the TS-570D.  I set Menu option #35 to 9600 baud, one stop bit.  I have Windows 7 device manager set the COM1 port at 9600, 8,N,1,   and have HRD set to 9600. I’ve tried every combination of settings on HRD for the TS-570.  But the Frequency read comes back with Zero.
What else can I check?
Thanks.

Did you try to set it to 4800 baud? Also make sure the CTS and RTS are checked and the DTR is unchecked

Also if you are using a USB to Serial adapter some of them do not work with HRD

yes, I' have tried every combination.  Even if you check the DTR,  according to HRD it has it set to OFF.

I have a USB to the SignaLink USB, and a DB9 Serial cable to the TS-570D.
I'm not sure if that is what you are refering to?

Its a  Female to Female DB 9 pin cable.

I assume you checked baud rate set in menu on radio as well. You MUST use a null modem adapter or cable with a USB serial adapter or it will not work.

Some rigs will only work with HRD when they're in "VFO" mode -- they will _not_ work in "Memory" mode.

If the TS-570D is in Memory mode, try VFO mode instead. 

Also, does the TS-570D manual say that it will work with a "straight-thru" DB9 cable?  Or do you need a "null modem" cable?

I own a 570 and have for many years and it does not care what mode it is in to RC it and it does require a null modem in circuit somewhere. Either in cable or adapter or it will not work. Some USB to serial adapters are made to control radios/modems and have null built into them. If you do not have it in circuit somewhere it will never talk no matter what setting you use. BTW I use 19,200  8N1 with hardware flow control with my 570.

I thought I was told that should be a straight DB9 and NOT a null modem cable?

Thats the problem. I was led to believe it was NOT supose to be a Null modem cable but a straight DB9 cable.  Looks like I'm in the market for another cable.

thanks

You should be able to buy a DB-9 null modem adapter -- a plug and a socket, cross-connected.

You do NOT want a null-modem cable.

The '570 radios require a STRAIGHT THROUGH serial cable for rig control.

Yes, both the NULL modem cable and the straight cable work (or fail to work) equally well at this point.
