RE: HP48G Connectivity Method in 2022
Hi Bob:
Thanks again for your attention. I have verified that it is not the cable. I've tried this with several machines and a couple cables. I'm using a modern 'gearmo' USB/RS232 cable with FTDI chipset) (My interest is with HP48G and HP48G+, so RAMCARD is not an option.) All other functionality of the connectivity works. It would be interesting to understand why the calculator shows an 'EVAL STOP' in the display and will not continue. I have shut off clock display on the subject calculator. I tried a lower (2400) baud setting, but the Conn software insists that the backup be done at the highest communication speed. I will continue 'fidgeting'. TomC ps: It is worth noting here that for cleaning contacts, one should avoid 'rubbing alcohol' as this has lanolin added. One should use the highest available strength of 'Isopropyl Alcohol' as this should not contain any additives. (09-18-2022 12:56 PM)rprosperi Wrote: Tom, |
