MIDI setup with Entex Pro MKII

[DanDrumDK]

Hi there,
I have a porblem with setting up the midi function on my Enttec Pro MKII.
My setup:
I am triggering midi program change with a Roland SPD-S drum samplepad into QLC+. Every pad has it's own midi notenumber that refers to my buttons in vitual control in QLC+. Recently i upgraded my setup with the Enttec Pro MKII with the 5 cable breakout cable (Including MIDI)

With my old USB>MIDI device it was simple to click on the device in the in/output page and simply define on whick midi channel i am sending/recieving my midi program changes.
With the enttec i don't have this opportunity. Can anyone tell me how to set up the MIDI program change function using midi channel 4 with my Enttec?

Thanks in advance

Is the pruple led flashing when sending?
I think I've read somewhere that the break-out cable from enttec is faulty (When I remember right the midi-GND isn't connected)
I can't give you a direct link to the forum where I read it ...

Good luck
