For equipment with ACS code coding protocol, it is necessary to remove the check box in front of hexadecimal sending and hexadecimal display, and select the check box in front of "Send new line" (because commands in ACS code protocol usually end with carriage return, it is necessary to add a line break after each command). Only in this way can we communicate with the equipment correctly.
SSCOM basically needs to select the corresponding "serial port" after opening the software, select the correct "baud rate", and then click "open serial port".
