This is a small summary of possible interfaces for FMS. Good study!
The general rule : the PC needs from your transmitter the following :
a) the ground
b) the PPM OUT-signal
How to find those 2 contacts on your buddy connector or how to find the
connections in case your transmitter is not fitted with a buddy box
connector, check out my website (http://users.belgacom.net/TX2TX ) chapter 1
A) For Win 95-98-Millennium with FMS, 2 easy possibilities (above all
possibilities that are also possible for Win 2000 and XP, see section "B").
1) THROUGH THE PARALLEL-port (LPT1)
eventually with a resistor and zenerdiode, see the manual of FMS
c("handbuch" in German)
(http://n.ethz.ch/student/mmoeller/fms/index.html ) or some examples on my
website which I personally tested (http://users.belgacom.net/TX2TX ) figure
7f-fms and others in chapter 7. Or here : http://www.pibros.de/ (German).
2) THROUGH THE SERIAL-port
See the manual of FMS ("handbuch" in German)
If you think you're not able to make such a cable, buy eventually one :
B) For Win 2000 and Win XP with FMS, a SIMPLE connection through the
parallel-port or serial port is not working, those 2 versions of Windows are
handling other protocols on these ports than Win 95-98-Millenium.
Your options then :
1) VIA PPJOY
By downloading and installing PPJOY and connecting your transmitter with a
simple parallel or serial interface.

installation : http://www.geocities.com/deonvdw/Docs/PPJoyMain.htm
2) THROUGH THE SOUNDCARD
With smartpropo : http://www.sekiriki.jp/smartpropo/manual.html
The advantage is that it's simple to make : 1 audio-cable and a resistor or
3) THROUGH THE SERIAL PORT (Com-port)
a) via an interface with a programmable IC (PIC), which is described in the
directory of FMS, see .FMS\Doc\Interface\readme_en.htm on your harddisk.
Or "Simple PCM" : this one has the advantage to use the power of the
transmitter and not by the control-signals ofthe PC. And as such is neither
depending on the system settings, neither of the used program :
b) or the same electronic interface that you can buy ready to use here :
4) THROUGH THE USB-port
(German : kit)
If you have a 4-axis joystick, you can use an interface-cable
gameport-->USB, for sale in every computershop, thus ideal for modern
laptops without a COM-port
5) THROUGH THE GAME-port
a) with an interface which transforms the signal of the transmitter in a
b) buy a 4-axis-controller joystick
c) or make yourself a 4-axis joystick with an old RC-transmitter, removing
all electronics, replacing the 4 potmeters by potmeters of 200K (not 100K
like mostly mentioned), and wiring like in :
6) Or make a partition on your harddisk where you will install Windows
95-98-Millennium. Then you can connect your radio simply via the
parallel-port or Serial-port as described in the manual of FMS and start the
older Windows (see section "A").
Hope this helps,
