FSUIPC and PMDG setup

[jeolmos 1]

Using FSUIPC PRESSES KEYS tab could configure how many switchers (Landig Lights, Taxi Lights, Battery, etc.), with optimal use in various aircraft. 

For the PMDG B738 NGX, I followed the following steps. 

For example for the No. 1 no keypad, operate the Landing Lights. 

a) In the FMC I deleted the default mapping and indicated that option (No. 1) 

b) In the FSUIPC, PRESSES KEYS tab, I select key 1 (non-key) and indicated that this key will operate as ON and OFF for landing lights, drop down menu for each case. Indicating parameter 0 for OFF and 1 for ON. 

Result: the respective switcher (Landing Lights) in the Overhead Panel turns on and off until I return permanently tighten the No.1 key. 

How I can fix this? 

The proper functioning should be, activated key N ° 1 = on landing lights. Off N ° 1 = landing lights off key. 

From already thank you very much for any help you can give me. 

 

P / D. I have "walked" several hours and countless websites, unable to see a solution. Clarified that also deleted the file FSUIPC.INI to leave "clean" program. I have paid and registered version of FSUIPC.
