Thanks for the information, segurant. We have updated the advise in the main topic introducing the UCM/Velbus.
The hardware flow control pins are required by the VMB1RS in order to send out data to UCM/Velbus.

The UCM/Velbus in future will  be supplied with a RS232 Male connector and a Male to Female straight RS232 cable so that it can be directly connected to the VMB1RS

The plug in RS232M can be plugged in to the UCM/Velbus base board in place of the RS232F

Those who have a trial unit UCM/Velbus can request the RS232M from us at no charge

The plug in RS232M board is shown below
