8 PORT SERIAL CARD: Serial controller card w/ 16C1050 UART based on the Systembase SB16C1058PCI, w/15kV ESD, 8x DB9 ports, bi-directional RS232 speeds up to 921.6Kbps per port & 256 byte FIFO buffer | An upgrade to our popular card PEX8S950LP.PCIe cards known to work with LinuxCNC >= 2.7. NetMos MCS9865IV-AA needs epp_dir=1 option ITE8875 chip (may not work on some HP motherboards) PCI cards known to work with LinuxCNC = 2.7.8 That does not work with PCIe parallel ports made by Startech, SIIG and Rosewil using the Oxford OXPCIe952 chip.

?EMC2_Supported_Hardwareįor LinuxCNC versions before 2.7.8 (March 14, 2017), the PPMC driver always forces the port direction change. docs/2.5/html/examples/pci_parallel_port.html The individual pins are addressed simply by their numbers, as per the base parport eg. The extra parports are addressed in the hal file by incrementing numbersĠx378 is parport.0, 0xc000 is parport.1, 0xb800 is parport.2 etc.Įach extra parport needs to be attached to a thread ie. pins 2-9 are output.Ġxc000 and 0xb800 are set as input, which sets pins 2-9 as input, allowing many sensors, encoders, switches etc to be attached Loadrt hal_parport cfg="0x378 out 0xc000 in 0xb800 in"Ġx378 being the computer port, used for stepper step/dir etc. On this card, 0xc000 was the port on the card and 0xb800 the port connected via the flyer ribbon cable. See link to Big JTs port tester as one option to test.Īnother simple option is to move a known good signal wire (from a limit switch say), from the BOB connected to existing port, to new BOB and activate the switch whilst watching the relevant pins in Hal Configuration window. Work your way through them, connecting in the hal file as below.

This is a dual port card, some trial and error is required to establish which addresses are the ports and which the registers.

The Oxsemi (PLXTech now) OX16PCI954 is recommended by one of the major manufacturers of such FPGA cards.ĮPP isn't needed for stepper systems as the input and output pins are in separate groups in the other modes. To communicate with other EPP interfaced FPGA cards, requires a parport card that properly supports EPP. Other chipsets work too, described in the hardware link below. The 9845, 98 chips (often designated MCS9845, MCS9865 and MCS9901) work fine Try to avoid the 98 chips which are quite old and were a bit flakey, often difficult to set as input. These are the most widely used chips by card manufacturers, irrespective of what the actual card is branded as. There is an added safety net with a PCI card, shorting out the parport will not ruin the on-board port or even the whole MB.įor stepper systems the NetMOS / MosChip chipset works fine.

A PCI parport card can be used to provide extra IO very cheaply, or even enable a computer without a parport to run Linuxcnc.ĭual headed (2 port) cards are very useful, especially where PCI slots are scarce.
