    COM2 determines the end of a command string when it encounters the 0x0D (CR) character. When manually entering individual command characters using a PC terminal application, the 0x0D (CR) character must be sent as the final I-7521/I-7522/I-7522A/I-7523/I-7524/I-7527 User’s Manual,Ver2.5 Aug.2015...
