Introduction

Geomet Versions - 6.66.006.001

The U/V Rotary Table is connected to the CMM through the Helmel ProCounter II CMM Interface. The interface is a digital 3 axis counter card with quadrature digital counters that supports all major brands of digital encoders.

Geomet communicates to the ProCounter II through a USB serial link and a resident ActiveX control referred to as a CMM Interface. When Geomet is installed on new systems, select the ProCounter II CMM Interface. The installer will register the ProCounter II with the Windows system making it available for Geomet.

If you are adding the U/V Rotary Table to an existing Geomet system, you will need to re-run the Geomet Installer from the supplied CD and choose the ProCounter II CMM Interface.

Connecting the U/V Rotary Axis Table

DSub 15 ConnectorThe U/V Rotary Axis Table is connected to the X(U) and Y(V) Axis Scale D-Sub 15 connectors on the rear of the ProCounter II CMM Interface. The Z Axis and Touch Probe connectors are not utilized.

Connecting the ProCounter II to the PC

USB A-B CableThe USB cable has a Type A connector on one end and a Type B on the other end.

Connect the Type B connector to the mating connector on the rear panel of the ProCounter II Interface.

Connect the Type A connector to a open USB connector on your PC. If you do not have a open USB connector, you may need to purchase a USB hub to extend your capabilities.

If the ProCounter II is powered up when you connect to the PC, Windows will inform you that new hardware has been found. Follow the recommendations to install the new hardware. The rotary table is now ready for use.
