Steve, I've not been able to get my Belkin to work on XP. Others have but I
You may not want to use the Belkin. I've updated the USB page and moved it to
It's now at http://www.rttycontesting.com/usb.htm. For those that are looking
for a true USB adapter that will do FSK under XP, Microham (www.microham.com) is
currently working on one but it's not out yet.

Subject: RE: [WriteLog] MK-1100
I am interested in the MK-1100, but I need a better understanding of its
operation than I could get from the website description. I will refer to
connector labeling that is shown on the website prototype.
If I am using WIN XP, will I still need to install UserPort, or equivalent, to
make these ports available? PC Connector: If I happen to be using a computer
with no serial port, will a USB to Serial Port adaptor (such as the Belkin
that AA5AU recommends) make the conversion for me? Rig Connector: What is
this? Rig control? Please tell me lots because I don't know this stuff well.
Rem Connector: What is this? Also, is there a listing of what all is
available on the LPT port pins? I ask this because I read that not much
documentation comes with the Multi-Keyer. Perhaps that is not the case.
in advance. 73, Steve, K4FJ
The parallel ports on the MK-1100 do not need the UserPort driver. They are not
full LPT ports--plugging in a printer would not do anything useful. They have
the band decoding outputs (on pins 2,7,8,9), CW output on pin 17 (which
duplicates the signal on the phone jack, but in TTL level), PTT otuput on pin 16
(which duplicates the signal on the PTT phone jack, but in TTL leve), and an L/R
on pin 14.
The USB to Serial port devices that I have tried don't work as well as I would
The signals all make it through, but slowly enough that you can feel a slight
delay when you, say, press the cursor key on WriteLog to switch from radio L to
R. The problem is that the USB-serial adapters have very large delays in some of
their RS-232 signals. Built-in serial ports always work very well, and PC-Card
serial adapters also work well (but are far more expensive).
The Rem connector is where you plug in the provided speed knob and L/R switch
"remote" box. Its small box with a knob and a switch you can use to control
those two functions with WL not running (or with WL running).
The "Rig" connector is there because the MK-1100 is designed to go "between" the
PC and the rig on the RS-232 line the PC uses to interface to the rig. So it has
a connector for the cable to the rig, and another for the cable to the PC.
