So I just picked up an old h500 with m-32 control. Previous owner was able to send EIA programs back and forth, they had it hooked up direct to computer. I'm using DNC one reader --- https://www.ebay.com/itm/USB-READER-...-/252839278228 - I was using this on my old Ikegai lathe and it worked fine. After playing around for a while I was able to send programs from the mazak to the reader but am not able to send it back. any suggestions??
