\u2022 Mount a total of up to 16 CPU Bus Units, including these Serial Communications Units, to the CPU Rack or Expansion Racks to create systems with up to 32 serial communications ports.<\/p>\n

\u2022 Connect an NT-AL001 RS-232C\/RS-442A Link Adapter to the RS-232C port to enable 1:N communications.<\/p>\n

\u2022 With the CJ1W-SCU[]2, you can use a faster baud rate (up to 230.4 kbps) and faster data transfer to the CPU Unit to enable connecting to high-speed external devices.<\/p>\n

    \n2803 hex: FIN header removed and converted to Compo-Way\/F command.
    \n2804 hex: FIN header removed and converted to Modbus-RTU command.
    \n2805 hex: FIN header removed and converted to Modbus-ASCII command.

    \n*2. When a timeout occurs, the FINS end code (0205 hex: Response timeout) is returned to the source of the FINS
    \ncommand and a response is received after a timeout occurs.
    \n*3. When a timeout occurs, the FINS end code (0204 hex: Remote node busy) is returned to the source of the FINS
    \ncommand. The send processing will not be executed and the received FINS command will be discarded.<\/div>\n<\/div>\n<\/div>\n
