The Multiport II MCA module provides greater flexibility than traditional bus plug-in boards but at a comparable cost. It can be purchased in versions from one to six inputs. Units with fewer than six inputs can be field upgraded with additional inputs.

The Multiport II module is easy to install and easy to link. Host computer interfacing is accomplished via a standard USB port or a standard Ethernet port (unshielded twisted pair) and through standard protocols. These widely recognized interfaces make the unit compatible with a wide range of computer platforms. Also, multiple Multiport II units can be totally remote-controlled from a single computer. Furthermore, there is only one cable between the host computer and the Multiport II NIM module for simplicity of inter connection.

The location for these files is the "C:\GENIE2K\DRIVERS\"; where "C:" would be replaced by the drive letter of the disk where Genie 2000 was installed. With these files in place you will be able to define Multiport II inputs using the Genie 2000 MCA Input Definition Editor.

Additionally the Genie 2000 installation does not create required registry entries for the Multiport II. The file MP2.reg is provided on the driver installation disk to create the required registry entries. Right click on the MP2.reg file and select the Merge operation to update the registry. Answer affirmatively to messages asking you if you really want to perform this update.
