Fanuc PPR - Paper Tape Punch, Printer and Reader : Not quite working

[Martin Bishop]

Eric

Thank you for the manual and the suggestion of pulling all the jumpers.  With all but jumper 1 out, it punches and remote starts (Xon) the reader at 4800 8N1; unchanged functionality.  However, still, nothing is emitted from the 232 for consumption by Putty.

Unfortunately, the SystemP manual contains identical pages on the PPR to those in the PPR’s own manual.  Nonetheless useful as context, and for perusal in slow time.

Here you are, I knew I scanned the manual. This has all the jumper settings, and instructions on local vs remote modes.

Hi Martin, I use the PPR for all kinds of paper tape shennanigans.

Remove all but the first jumper, and that may help with your issues. I found at one point the jumper settings, but will need to search.

A nicely made yellow box with a rather poor manual - both lost in translation and limited in scope.

Working on setting one to work, but can't get anything out of the serial port.  In drives the punch, and the punched data verifies (based on a QL).  In also drives the printer, although somewhat garbled, perhaps due to BCD coding or perhaps due to invalid parity (which is configured as no check).  The reader 'reads' tape both in response to X/ON over RS232 and in response to front panel keys.  However, nothing is emitted onto 232.  The D25 - D-9 transition has all the RTS/CTS and DSR/DTR/DCD lines knitted appropriately and indicating 'correctly' on blinkenlites.  Interestingly, on long test tapes the reader does not fall off the end but stops, repeatably after ~49" which is remarkably close to 512 octets.  Finally, the CNC termination octets : % (ASCII) and 0x80 (BCD : RS-244) don't seem to impress the reader - nothing changes.

Specific queries:
- Are there any magic control codes or handshaking rituals to coax data out of the reader
- Is the PPR to CNC Controller interface protocol manual available as pdf
- Where can I find drawings for the PPR's electronics, most importantly the main board (with its 8031)
- Suggestions on how to proceed with setting to work / fault diagnosis
- Has anyone house trained one of these to read PDP-11 absolute binary tapes, their target market was G code (text)
