Multi I/O Card/USB Hub Connectivity


Add-in Multiport Communications Cards for PC's or Muiltiport USB Hubs expand the serial communications capabilities of the PC beyond the standard none, one or two ports. These ports offer one connection per CNC machine, making switchboxes redundant.

 

The Multiport Communications Cards are available in 2, 4, and 8 port versions.  Several Multiport Communications Cards may be installed in the same PC.

 

The Multiport Communications USB Hubs are available in 2, 4, and 8 port versions.  Several Multiport Communications USB Hubs may be installed on the same PC.  Once the multi I/O boards driver software is loaded the Windows operating system will recognise the individual ports which are numbered COM11 to COM12, COM14, or COM18.

 

Using Multiport Communications Cards for PC's or Muiltiport USB Hubs will increase the cable run distances.  If your DNC computer is located in an office environment then a cable from each machine will have to be run to the office. This can entail having to drill holes through walls and ceilings.

 

Example of an 8 Port I/O Board Setup.

 

The 8 port multi I/O board is plugged into one of the computers internal PCI slots. An octopus cable is then plugged into this board thus providing 8 individual RS232 ports. An RS232 cable is then run from each machine control through the workshop and connected to the octopus cable.
