Multiplex 4000 More Programming Questions
Other brands of radio can hard-code into the processor whether a switch is 2 or 3 position since the radio comes like that and you can't change it. Multiplex expects you to fit what you want so it can't hard code an input as being a 2 or 3 position switch, therefore you have to select it in software. This applies only to secondary switch inputs S01-S12, a control input G-M expects a proportional input so they interpret 3 position switches correctly.
To tell the radio that a switch S01 - S12 is a 3position switch, assign a Transfer switch to it. Transfer switch is the 3 position software interpretation. Then when you want to assign parameters like mixing or expo to that switch you assign them the T switch, not the S switch. You can still assign things to the S switch which behaves as a 2 state switch while at the same time assigning things to its 3 state T switch!
Menu 2, switches, scroll to Transfer sw: T1
then choose From switch S12
Now assign mixers, expo etc to T1 and not to S01 or S12. Assign switch in the normal way, keep scrolling up through the list and you will find T1 comes immediately after S12. However there is a crucial difference between assigning an S or T switch. You just get one menu option for each S switch and toggle its on/off state using R. With T switch keep scrolling and you will see there is T1-1, T1-2, and T1-3. These correspond to the 3 possible switch positions, T1-3 is switch up and T1-1 is switch down T1-2 is middle. You assign the position that you want. Lets say you want switch up (T1-3) to be the ele->flap mix. Go to menu1, servos, flap servo, ele input , make sure that you put the switch to the up position and then set switch to be T1-3*. If the asterisk is not there with the switch physically in the correct position, press R to bring it on. If the * is on in one position it is off in both other positions. If you leave the * off in one position it is on in both other positions, useful when you want something off in one position, flight mode etc.
If you want switch down to be the mixer, then set the switch to be T1-1*
Go to expo and set switch to T1-X* where X is the position you use to switch the aileron on. You may wish to reset the aileron input in the flap servo to T1-X rather than to S12.
