[WT-support] Interface

[Bob Wilson, N6TV]

Alfredo,

See this link <http://home.comcast.net/~k8cc/MFJ432_Voicekeyer.htm> for a
circuit you will have to build to connect our MFJ-432 to your computer's LPT
port.

The MFJ-434B already has a "Remote" connector that you can connect directly
to your LPT port.  This is described in the MFJ-434B
manual<http://www.mfjenterprises.com/man/pdf/MFJ-434B.pdf>
.

In Win-Test, the LPT
Properties<http://docs.win-test.com/wiki/Menu:Options#Printer_Ports>dialog
documents what signal is on each LPT pin.  You must check the
appropriate "DVK" boxes for each pin you connect to your MFJ Voice Keyers.

If your computer has no parallel ports (no legacy LPT port), you will not be
able to control your MFJ boxes from Win-Test unless you install a parallel
port card or USB-to-LPT adapter (though many of these adapters are only
designed to support legacy printers, and they may not be compatible enough
to work with Win-Test for DVK purposes).

To use the Win-Test internal sound card DVK, connect your mic. to your PC
sound card and your PC headphone/speaker output to the mic. input of your
radio as shown here <http://docs.win-test.com/wiki/Interfaces#Sound_Card>.
