Hello, all,
I sell a line of motion interfaces for LinuxCNC, and supply Syba PCIe
parport cards to go with them. I am retrofitting a Bridgeport R2E3
mill for my own use, and bought a Dell Optiplex 7010 computer to run
it. I cannot get the Syba cards (with NETMOS MCS9900 or MCS9901
chips) to work at all in these machines. These are my only PCIe
motherboards. I do have one Siig card with a Oxford OXPCIe952-FBAG
chip that works with LinuxCNC but does not work with my diagnostic
program. I have loaded it with the LibnuxCNC 2.8.2 rt-preempt DVD
live download file.
Is there anybody who has used Pico Systems products with PCIe parport
cards, and can you report what does (and DOESN'T) work, in terms of
what LinuxCNC version, kernel, motherboard and parport?
I am trying to diagnose whether this is a 64-bit kernel issue, kernel
version issue, motherboard chipset or configuration of the parport
card. Most of these parport cards have programmable I/O chips, where
the PCI config ROM can set up the address mapping of the various
device registers, and the issue might be that the newer cards I have
have changed the address of the extended control register that selects
the parport mode to bidir/EPP/ECP etc.
I have ordered a Dell Optiplex 980 (last of the line that has an
on-mobo parport), that should tell me whether the issue is the PCIe
cards or the kernel.
Thanks much in advance for any experience anybody has with this!
Jon

PCIe MCS9900 strangeness: Capabilities: <access denied> Saw this helping
someone with the same card a few months ago on IRC.
LCNC 2.9 Stepconf does not recognize the card either.

I marked this card as working OK a few months ago.
