Suppress of repeated signals

Hi,
I'm using USB-UIRT (plugin version 3.2.1, API driver version 2.6.98, Firmware version 5.9) and Girder 4.0 to receive signals form Philips Pronto Pro.
It works fine. The only problem is that all of the Pronto's signals are received twice.
Can I suppress the repeated signals somehow?
Thanks in advance
