No I have not seen this in the HMI, My Tech support at Ruida only advised this method of changing the Blow Mode. I have heard that later versions of RD Works do not have this option in the User Tab.
Also note: I have seen some reference in this post relating to updating firmware. Please note if you do upgrade Firmware to RDLC-V15.01.18 it may disable your Auto Focus for those who have it installed. To enable it again it seems like the HMI does not activate it when you select Focusing Yes, but you can re-enable Auto Focus in the User Tab of RD Works v8.01.47 as shown in image attached.
