Suggestions for CNC serial expansion to multiple plasma systems
The following are suggestions to allow a single CNC system to interface to multiple HD4070 plasma systems using
the serial interface. Contact Hypertherm Engineering for more information.
1. If the CNC controller is a PC based controller then possibly the simplest way would be to add an expansion
I/O board with the correct number of RS422 serial ports. These expansion boards are available from a wide
variety of vendors. Obviously the software must be developed to support the dedicated port for each plasma
system.
2. If the CNC controller is limited to a single serial port then it may be possible to externally add a software
controlled serial switch. This type of device intercepts control codes over the serial link that are used to switch
the serial connection to any one of several available channels. Once again the CNC software must be
developed to support this type of device. Devices of this type are available from BLACK BOX INC. and their
telephone number is (877) 877-2269.
3. If the CNC controller has an ethernet connection then it is possible to use an ethernet to serial converter such
as those sold by LANTRONIX INC. (949) 453-3990. These devices have a settable IP address and can be used
to provide independent serial interfaces to each plasma system. Once again the CNC software must be
designed to support this approach.
Single machine configuration
Switch number 4 must be in the ON position in a single system configuration. Switch 1, 2 and 3 are OFF.
