The 'Y' Cable


The information and design here may be used and distributed
freely as long as no profit is gained ! Thank You.

 

This is the 'Y' cable that will allow you to use the CH Throttle or CH Pro Throttle without
loosing the HatStick function of a Logitech Wingman Extreme, Thrustmaster Mark IV,
MicroSoft Sidewinder 3D Pro (in Thustmaster mode). I believe the 3D pro will also still
work in digital mode. A friend has said it does, I have not verified it.

Normally the analog throttle output and the hat stick both want to use the "Y2" axis. This
cable allows the Joystick to feed straight through maintaining the hatstick function while
shifting the analog throttle output to the "X2" axis. This is a great combo for Descent and
Descent 2.

If you are using a CH Pro Throttle with this configuration you can incorporate other
controls via the 15 pin female 'D' connector on the back of the Pro Throttle. Since the
the Pro Throttle allows you to redefine joystick switches you can rig up special controls.
If you would like more info on this drop an email to at the address below.

 

In Descent 2 you simply select joystick as you normally would,(Thrustmaster FCS &
Wingman Extreme). Then choose the "customize above" menu option. Select "Throttle"
at the bottom right of the screen. Slide the Throttle back and forth and X2 will appear
in the box. Exit the screen and calibrate as you normally would. The last thing the
calibration routine will ask you to do is move the joystick X2 axis all the way to left
(slide the throttle forward), then to the right (slide the throttle back). You are all set.
We have noticed that from time to time when calibrating the throttle then does not
work, this appears to be Descent 2's problem, simply recalibrate.

In Descent 1 it is a bit more difficult since they seem to assume that if you have a
hatstick you won't have a throttle. Select the joystick as you normally would,
(Thrustmaster FCS & Wingman Extreme). Then choose the "customize above"
menu option. Select "Throttle" at the bottom right of the screen. Slide the
Throttle back and forth and X2 will appear in the box. Exit the screen and
calibrate as you normally would. Now the hard part Descent won't ask to calibrate
the X2 axis, and infact will force zero values into the file for that axis. Using an
ASCII text editor (MSDOS Edit will do) edit the "DESCENT.CFG" file in the
descent directory. Near the bottom you will find three lines that appear similar to
those below.

Example:
JoystickMin=20,21,0,0
JoystickCen=402,400,0,404
JoystickMax=800,804,0,801

The easy approach is to simply copy the value from the 4th
place of each line to the 3rd place. For example.

(before)
JoystickMin=20,21,0,0
JoystickCen=402,400,0,404
JoystickMax=800,804,0,801

(after)
JoystickMin=20,21,0,0
JoystickCen=402,400,404,404
JoystickMax=800,804,801,801

This should work fine, the one problem with Descent 1 is that every time you
recalibrate the joystick it will zero out these numbers, and you will have to
re-enter them. There may be some solution to this but I have not had time to
look into it, and really don't play Descent 1 anymore since Descent 2 came out.
There are some more advanced and more accurate ways to determine the values,
if you are really interested email me.

All other(unshown) pins are not connected. Also, of coarse the CH Throttle/Pro Throttle
still plugs into the keyboard. For futher info or help email me at ktmurphy@ix.netcom.com

Good Luck, and I'll see you in the mines...........
