4.Firmware update
    For NCT08-02 it's possible to upgrade firmware via communication tools.
    Here is an overview of operation.
    It's possible to use USB and LAN communication.
    This is an example to install software by free soft "Tera Term" using LAN.
    
    ① Fist download the version upgrade software by Internet then unzip the file.
    ② Run "Tera Term" software.
        In case of LAN mode, select "TCP/IP" enter IP address and port NO. of  NCT08-02.
    In case of USB mode, select "SERIAL" and click PORT number (COMX) which is assigned to USB port.
       Operate "SETUP" to "Terminal", set  "New-line" is CR+LF with Receive and Transmit usage.
        Put check mark into Local echo, then select "OK".
        Try put into command "VER?", then if there is reply, connection will be no problem.
        
    ③ By "Tera Term", select "file" and then click "send file".
      Opening "File Selection Window", specify the file name which is already installed procedure ①.
      Then it begins the download.

    ④ it's possible to check download program file by PC. 
         When receiving data, the "COUNT" LED lamp of unit NCT08-02 turns on and off slowly.
        
    ⑤ After receiving data for about 20s, the "COUNT" LED lamp goes to fast on and off mode then ROM writing 
        session begins. After 5s, "COUNT" LED lamp turns off then this session will be done.

    ⑥ Stop "Tera Term" then cut off the line TCP/IP or USB, turn off power line of NCT08-02.
         Turn on power of NCT08-02 again, the firmware version will be new.
    Without turning off power line, it gets start by "RESET" command.
    There are two pieces of flash ROM(FROM) loaded inside, new firmware is installed to one piece 
    which is not used at now. After finishing writing a session, new one (written just now) is activated.
    So after this session, by power off/on sequence or "RESET" command, new program will start.

    It is possible to check the version of working FROM by the command "FROM?"
      Reply data is like these,"FROM0", "FROM1".
    It is possible to specify the version of working FROM by the command "FROM0" or "FROM1".
      After specifying FROM version, turn on power action or "RESET" command will start again by specified 
      FROM version. It is useful to compare old and new firmware version.

    If you miss the download work and program doesn't work, it's possible to recover initial version firmware 
    by the ROM print board inside.
    This is the procedure of recover the program to initial state.
     1.Cut off power line, open the left-side cover panel. Slide the dipswitch 2 "ON" side.
       Dipswitch 1 keep "OFF" side.
     2.Put on power line while shortening "GATE" input signal, "COUNT" LED turn on and off for about 15s.
       After that "COUNT" LED turn off and session will be done.
     3.Put off power line again, then slide the dipswitch 2 "OFF" side. Dipswitch 1 keep "OFF" side.
     4.Put on power line again then program starts by initial version.
    
    From now the latest file must be installed by procedure ① to ⑥.
