We have a 2005 Daewoo Puma 2000LSY with Fanuc 18i-TB control. We are attempting to transfer files between the CNC and PC via 64MB compact flash card + adapter.

We have been able to transfer files from the PC to the memory card and then from the memory card to the CNC, but when we try to output programs from the CNC to the memory card, it gives alarm "086 - DR SIGNAL OFF".

I believe this is because it is still attempting to output to the serial instead of the memory card, but we have not been able to fix this. Under "Setting [HANDY]" we are set to I/O Channel 4 for the memory card.

Any help would be appreciated, thank you.
