the digital output drop to 0

Hi,

i have this circuit to control the direction of brushless dc motor
to remove the brake the brake should connected to Black and this happen after i give D0 and D3 high and this one work fine
to move back same we have to connect brake + back + black then D0+D1+D3+D4should high and this one work fine
when i want to move Forward should BRAKE+BACK +FRW+BLACK then the 6 pins should be high , but in this situation all the pins is low
any suggestion ?
the module i have 9403 and cdaq 9188
