Using Ryan's wiring the code might look something like this:

Channel5=Get RxInput (1,5);
Channel6=Get RxInput (1,5);
 
if (Channel5 == 1) {
    // forward
    Set Digital Output (1,1);
    Set Digital Output (2,0);
} else if (Channel6 == 1) { 
    // reverse
    Set Digital Output (1,0);
    Set Digital Output (2,1);
} else {
    // stop
    Set Digital Output (1,0);
    Set Digital Output (2,0);
}
