*3 For MECHATROLINK-I, only a 17-byte data transmission can be selected.
*4 The maximum number of stations that you can connect is different for different host controller types, and baud rate and
communications cycle settings.
Communications cycle: Integral multiple of transmission cycles (depending on the host controller settings).
For details, refer to the manuals of your controller.
Example: If the host controller is an MP2300
