Now I got confused. What you transfer via ZMODEM and Hyperterminal is not a profile? So, there are two kinds of files, the "generic software" and "the profile". If for some reason the board software gets corrupted and need to be reloaded using hyperterminal, what file is it? Then after that, the profile needs to be transferred? I already saved the profile and copied to the laptop with Win10, using TERATERM to communicate with board via Con6 (jumper3 on), since there is no more hyperterminal (windows XP). I am able to receive the "ZMODEM READY" from the board on the Teraterm, then when selecting the "profile file" to transfer via zmodem, few seconds later the board answers with "ZMODEM FAILED, No files recvd.". What is the UIT for 6300PA6 ?
