Optocore: How do I connect to Optocore interfaces?

Question:  I'm a new user to Optocore, how do I connect to the V3R-FX interface unit?  I see RS-232 connections, USB, and Ethernet connections.  Which one is the preferred connection mode?  Which PC platforms are supported by Optocore software?
Answer:  The simple answer is to use the USB connector on the front of the Optocore unit for the initial setup of the unit and setting the units node-numberonce all units are setup , you can access all the units on the Optocore fibre ring either by connecting to one unit via the USB connector or by attaching your PC to the one of the LAN ports of a Optocore unit 

To install OPTOCORE CONTROL you will need a standard PC computer running Microsoft Windows XP / Vista / Windows 7 operating system. The computer should be equipped with a USB interface for configuration and remote control of the Optocore network plus a Serial Port interface (or an appropriate USB to RS232 adapter) for firmware upgrades. COM Ports 1 to 4 can be used with a transfer rate of 57,600 Baud. Ethernet connections provide for programming of remote Optocore interfaces. 
Monitor resolutions of 800 x 600 or 1024 x 768 with 16 Bit color depth are recommended. The installation requires approximately 2.5MB of hard-disk space.  Please note that the serial interfaces on computers are not normally capable of “Hot Plugging”. Switch off the computer to avoid damage before establishing the serial connection between the Optocore device and the computer.
