Wayne,
cables are checked and are ok.
Keyer is always "Timeout" in the window.
I presume that the com port and ct-17 interface work because when I set com1
port and radio without the W5XD+ keyer, but CW generated by computer through
the ltp1 port, everything works perfectly as usual.
My suspects are now more then ever on some of Integrated.
How can I understand which one between MAX 202 and MC68H705?
Thanks
Gino

Oggetto: RE: [WriteLog] W5XD keyer
The main WriteLog window has a series of 4 status indicators across the
bottom. (Its possible you have turned them off, make sure View Status Bar
has a check mark.) The second one from the left indicates the keyer WPM
setting. If WL fails to communicate with the keyer, the WPM indicator
says "Timeout" instead of the speed.
In order to get the WPM display, these four lines on the COMM port must
be working: RTS, CTS, DTR, DSR (pins 4, 6, 7, and 8 on a 9 pin connector),
the MAX 202 chip must work, and the MC68HC705 chip must work (and the
5VDC) must work, but nothing else on the board is needed.
You can also check just the COMM port and cable if you can unplug the
keyer and construct a jumper of RTS to CTS and DSR to DTR (pin 4 to
pin 6 and pin 7 to pin 8). It won't debug the keyer, but it will
confirm that the WL software is set up properly and that the COMM
port is OK.

Dear friends,
after a lot of different tryes, I suppose that one of integrated circuit
doesn't work.
If I connect my radios directly to the com port everything is ok, but as I
go through the keyer no connection is shown both if plugged or not with DC
power.
Now how to understand which of these components is broken?
I think that or MAX202 or the original chip 10.19 or 74164 part is damaged.
I don't have spare parts, so I must identify which one is to be changed. How
to do?
By the way, thanks to all friend answering at my first message.
Gino
