TDC1000-GASEVM: No Signal in Short TOF Moden with Boosting Board

Part Number: TDC1000-GASEVM

I want to make Short TOF Measurement with a TDC1000-GASEVM. In Standard TOF Mode it is working as expected but as soon as I switch to Short TOF I can't get a signal to the transducer connected to TX1 on the booster board. Measuring TX1 on the connector between GASEVM and Booster Board i can see the 3 Pulses without amplification. Am I doing something wrong?
