Re: PIL-Box - communication with external HP71B

following you instruction I did not succeed with copying files from HP71b (HPIL ERR: Invalid Mode). Quite honestly, I'm lost and have no idea what to do next.

Any further advice.

I assume you tried this:

My recommended method for reliable communication between Emu71 and HP71 with the PILBox is to use the IL-Per software (available on my PIL-Box page): do not declare any XIL in Emu71.ini and use IL-Per as a gateway by sharing the hdrive1.dat file: You can now copy files between Emu71 and HP-71B. Do 'COPY file TO :HDRIVE1' on the one side, then do 'COPY file:HDRIVE1' on the other side. Fast and efficient.

The error "HPIL ERR: Invalid Mode" means the HP-71B is in device mode and you attempt to do a command requiring that the HP-71B is the loop controller - such as the COPY command above. So do CONTROL ON, then RESTORE IO (just to be sure), and try again...

In case of HP-IL problem with the HP-71B, it is always a good idea to do RESET HPIL then RESTORE IO. It solves a lot of abnormal HP-IL situations, that can happen very easily with this machine.

Do not hesitate to contact me directly if you have problems with the PIL-Box.
