But the 20 pin connector on the front of the shark controller is for the Next Wave laser module
NOT for controlling a spindle/router.

(Shark was designed to use a Bosch 1617 and 1618 (2.25 hp), Porter-Cable 890 Series (2.25 hp), and DeWalt 610 (1.5 hp), 616 (1.75 hp), 618 (2.25 hp) routers woodworking router (& NOT A VFD SPINDLE) so you are expected to switch on/off and change the RPM at the router itself I suppose)

Actually you're wrong. I sell the Sharks, and the 20 pin connector IS used on the front of the control box. They have a 20 pin connector that has a circuit board in the connector and it's connected to the VFD as it comes from Next Wave and directly plugs into the front of the box. You're spreading FALSE information.

Just show the OP the PINOUT
OK I am wrong!

No problem. Like other developers, Next Wave responded to the demands of their users since other systems had those capabilities. I, myself designed a simple relay system that plugged into the Router start plug that would start the VFD automatically, and just wired in a potentiometer to control the speed. Although 90% of the time I never change my speeds after starting a cut. Have a great day.
