4.4 Upload /Download by PTFile Manager

The way to upload /download by supervisor menu will need the operator to set the terminal to
supervisor menu by selecting Transfer in supervisor menu or calling system function n
application program.
PA20 can be instructed to process data communication by PTFileManager through built-in
MULTI communication protocol.
After linking the terminal to a PC/ host through RS232 / USB interface a communication
program running on host first sens a few of dummy bytes to the terminal and delay for about
500 mini-second to remotely wake up the unit. Then the program can send out a data pack of a
remote PTFileManager that matches the MULTI protocol to the terminal and instruct the
terminal for certain process.
For instance, the terminal will automatically execute the system routine to upload a file after
receiving the valid "File upload" PTFileManager. Meanwhile the program running on the host
should follow the control flow of MULTI protocol and process to receive the data.
