APR-2E / 3E have some additional settings:
...but i can't increase MODE/FLOOR first digit above 1 (IL-38 and TU-142)
Only available didits are "0" and "1" for every configurations ACTIVE/PASSIVE and CIRCLE/SNAKE.
edit:
For MK 50 and MK 54 first digit can be increase to 3 (0,1,2,3) - all works fine
edit:
For L5 and MK 46 (platform Atlantic MK 3) situation looks same like APR 2E/3E - i can't increase first digit above 1.
