Also to note... Linux doesn't support hot swapping of drives so you need to umount them before pulling. If you pull them without umounting more than a couple of times it will start ignoring the drive until you reboot.

I have a customer who has a 6U VME board he needs to integrate via VME64, I haven't used anything VME in ages. Are there any options in the PPMAC world?

Shadi, thank you for your offer of assistance! I have good news, there is no issue with the card or the documentation, although it is very confusing because of the orientation and arrangement of the jumpers. We were supposed to have 0-10V devices on our system but they were actually 4-20mA devices, so it appeared that things were opposite when the were not. We resolved this as soon as we took a look at all components, so this is not a Delta Tau issue after all. Thanks again!

Hello, I found this thread but I'm still having an issue on a system we're working on. http://forums.deltatau.com/showthread.php?tid=1005&pid=3878 We have 2 ACC-59E3 cards in our rack, and we intend for one to be voltage inputs and the other to be current inputs. Following the manual and the post above, we set the jumpers to 2-3 on the desired "voltage" card, and 1-2 on the "current" card. This seems to be backwards somehow. Can anyone else confirm this? I can't communicate from the job site and I need to be back there tomorrow, hoping I can get some confirmation before I go in and have a look at it again. Thank you! Steve

Hello, I have an application where we are logging data to a text file on a USB drive at /media/disk-0/ This is working, the file is generated correctly. However, I need to know if the USB drive is connected or not. If I try to write the file when there is no drive I get some watchdog issues in the background. So, can anyone tell me how to detect this drive? I don't care if it is through PMAC script or C code, either will do. I don't need millisecond frequency checking either, I can schedule it every second or so. I have tried stat() and it seems to always say the directory is present even when the drive is removed. so this doesn't work: struct stat st; if(stat("/media/disk-0/",&st) == 0) { bUSB_Ready = 1; } else { bUSB_Ready = 0; } I've also tried adding a directory in the root of the USB drive, I can tell the customer they need that for it to work (so it would be /media/disk-0/LOGS or whatever). When I try to detect that I never see the drive, even when it is plugged in. Ideas welcome! Thanks, Steve

I should add, I found these but I don't know if they are approved for use on the 11E http://www.microchip.com/wwwproducts/en/MIC2981

Hello, We previously stocked a few UDN2981 (or UDN2981A) in case a customer damaged an output, but we can't find them now. Is there a factory accepted replacement for these? The ULN2803 for the sinking setup seem to be easy to find still, but I can't find the UDN2981 Thank you! Steve
