Denford Software & Machines

How do I identify my Denford / Baldor control board and the software it will run?

1. Denstep board RED 7 Segment display, Orange Connectors, (RS232), VR Milling Ver 2
2. Nextstep board Green 7 Segment display, Orange Connectors, (RS232 / USB), VR Milling Ver 5 / VR Milling Ver 2
3. Nextstep board Green 7 Segment display, Black Connectors, (USB), VR Milling Ver 5
4. Nextstep board Orange 7 Segment display, Black Connectors, (ROHS), (USB), VR Milling Ver 5

I think the

3. Nextstep board Green 7 Segment display, Black Connectors, (USB), VR Milling Ver 5

will also run VR Milling 2

It is the Yellow RoHS compliant board that does not run the old firmware.
