Power Levels Reversed?

Hi All, I have had my new laser for about a week now and doing some light cutting work when I get time to play with it. I have a strange problem though which may be software related (not 100%).
My power levels seem to be reversed?????
When I select a low percentage on RDWorks my mA on the power supply goes high and vice versa.
Anyone have any idea why this would occur?
I have attached a chart of the 16 test measurements I hhave made, the blue bars are the percentages in RDWorks and the orange bars are the mA shown at the PSU.
Any help would be appreciated.
Regards,
Robert.

Which one (programmed power or mA) correlates with cutting ability? In other words, which cuts the material more effectively: high programmed power or low programmed power?

I suspect that the Signal Level in Vendor Settings does not match the connection between controller and PSU. Easiest way to correct this if I'm right is to invert the Signal Level in the vendor settings. Read from the controller, Save the settings to your PC, make the change, and Write back to the controller. Alternatively you could move the PSU connection from TL to TH or vice versa.

Thank you all for your replies. I had fixed this problem this morning but not had a chance to reply.
The PSU was connected to the PWM- output of the controller and swapping out to the PWM+ has fixed the issue.
I suspect that your solution Chris would probably have worked also, I have just done this on the hardware side rather than software.
I love the challenge of these Chinese lasers, you learn so much about them as you dive dealer into it.
