[cctalk] Re: Paper Tape Reader Needed

Folks The jpg I posted previously https://www.emeritus-solutions.com/papertape/fanuc/Pic16F13145FanucInterfac… says it all cryptically To unpack the approach: - ex CNC machine paper tape readers are available, the Fanuc ones are both common and susceptable to house training - so 1) is buy a fanuc PTR + interface : part nos and current picks below - the required supplies are 200 V 50/60 Hz ~23W, 24V DC at ~1A2, 5V DC ~325 mA - the Fanuc interface board is https://www.emeritus-solutions.com/papertape/fanuc/A20B-0007-075D_Ptr_Inter… series 74 TTL IO - my interface bodgit uses a PIC16F13145 EVB as it has 5V IO (which is just the thing for series 74) and some CLBs (a joke, but you have to walk the ground) - so 2) you need a https://www.microchip.com/en-us/development-tool/ev06m52a to convert parallel octets into serial output - the interconnect board is connectors and wiring, the one illustrated is built for ease rather than compactness - so 3) DIY time, [DrB] the wire list for marrying PTR and PIC[DrB] is in the .zip - a project archive for the PIC containing sources and binary is available for download https://www.emeritus-solutions.com/papertape/fanuc/FanucInterFace1.zip should contain working code for MPLAB/X - my Fanuc zoo https://www.emeritus-solutions.com/papertape/fanuc/visualise.php depicts the interconnect board https://www.emeritus-solutions.com/papertape/fanuc/Pic16F13145FanucInterfac… https://www.emeritus-solutions.com/papertape/fanuc/Pic16F13145FanucInterfac… FWIW I usually use a Zynq to interface PTRs, this design was an exploration of the 16F13145's capabilities, serendipitously providing a "uart" on an EVB solution The PTRs run the capstan continuously, the pinch roller is engaged by the centre off switch on the front panel: Manual - feeds tape, but does not assert DataValid; Auto - feeds tape and asserts DataValid. The PIC outputs octets when DataValid is asserted. The pinch roller is engaged when Auto or Manual is selected. The Brake Clamp is engaged when the NO foot pedal is closed. The PT feed is friction, the reader is opto with LED illumination. The A02B-0047-C061 is compact https://www.emeritus-solutions.com/papertape/fanuc/A02B-0047-C061_Ptr_Front…, but may not come with a Fanuc interface card A20B-007-075D https://www.emeritus-solutions.com/papertape/fanuc/A20B-0007-075D_Ptr_Inter… (which you will need). The A13B-0070-B001 is a 6U 19" rack panel https://www.emeritus-solutions.com/papertape/fanuc/A13B-0070-B001_Ptr_Bin_F… typically the interface card is attached to this panel So, picks from eBay.com are: https://www.ebay.com/itm/126851010269 https://www.ebay.com/itm/393980423195 although I have no idea if the PSU is any more than an ornament https://www.ebay.com/itm/233194641467 or https://www.ebay.com/itm/304005388602 plus https://www.ebay.com/itm/184870581852 or https://www.ebay.com/itm/293557099779 or with a diy panel https://www.ebay.com/itm/224491588288 etc etc More than one set of bits may be required to eliminate squeaks, but the simple PTRs usu seem to work Also, https://www.ebay.com/itm/150974081687 is RtR and uses the same IO interface card as its lesser siblings - I'm (still) reverse engineering the push button and remote logic which is for CNC Gcode use cases https://www.ebay.com/itm/167311496458 is 2nd generation RtR and I have yet to make mine work ...; item zero is stw a (mechanically damaged) AC PSU ... HtH, Fanuc also made a PPR Punch Printer Reader with a serial (usu 4800) baud interface https://www.ebay.co.uk/itm/405256535393 This cookery makes serviceable PTRs out of inexpensive pre used readers - ten times cheaper than a PPR ? And of course my wiring sheet tells you how to hook up to your favorite hardware - game on ?
