content: yepyou have at least 2 models on lpt the 48 and 48 lv and one in usb 48uxp if i recallthey had an upgrade option for the LV low voltage, it was simply a matter of changing one of the 2 pcb inside itand finding parts outside are .... even defectives theses units are sold way to pricey you have to search all models and odm one hoping to catch onein the end some good alternatives exists xgecu t48 t56 or the new t76 do a lot more, or many like mcumall g-q4x genius xxx top xxx models unless you go with the biggers ones like elnec beeprog, xeltec 5000 6000 ....series etc .... then TNM 5000 was doing all of theses dataman, TNM7000 more stuff prices ...if Dataman can salvage some parts or old board ? you never knowthe last free version was 8.32 you have version 10.xx but a 2 year licence need to be paid for more parts support

content: Quote from: coromonadalix on January 25, 2025, 01:42:16 pmAccording to the LV upgrade pdf on the Dataman site, you also have to change the PROM on the mainboard with the one supplied with the upgrade kit - so the PROM installed in the LV programmer needs to follow the top board wherever it ends up. I'm not sure what happens if you move it to a UXP variant as that has a different mainboard.
