I found this linked from the CNC4PC website: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Hooking_Up_A_MPG_Pendant so there should be no magic required to get this working. > So given that it might be working and given that I get the following > output from lspci -v how do I know which port address to use?

Don't forget the motherboard port counts too, but doesn't show up on lspci (hal parallel ports start at port 0, then 1, 2 ...). You will need to plug the pendant in and power up the PC, then set the EMC2 parallel port driver to each address until you get it to work. Don't forget to not only load the driver in your EMC2 .hal file, but also set up the functions (read and write port(s)) and hal connect the pins to something (or just use halmeter or halscope to monitor the pins). Stepconf might help to set this up: http://www.linuxcnc.org/docview/html/config_stepconf.html Don't change the parallel port connector while the PC is powered up because it will most likely burn out the port. If you are using a parallel port buffer or isolator, you may need to figure out how it expects to be enabled and how to set the data buffer to input or output. Sometimes a charge pump is used to enable the buffer, see here for more: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?About_Charge_Pumps You may also need to work out whether you need to have pull up resistors enabled on any of the port pins, and whether common terminals are grounded or pulled up. > I was planning on setting it up as an output to a stepper driver > (G540) as the initial test and then try to configure the MPG. http://cnc4pc.com/Files/PCIPP.zip PCI PP files, has the Moschip datasheet http://www.linuxcnc.org/docview/html/hal_parallel_port.html EMC2 parallel port driver notes http://www.linuxcnc.org/docview/html/hal_tools.html Halmeter, Halscope notes There may be other issues I've left out. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA The must-attend event for mobile developers.
