Note1) When connecting a commercially available device that has an RS485 interface, please confirm
operation using the actual device. In some cases, the number of units, transmission distance, and
baud rate vary depending on the connected device.
Note2) The values for the transmission distance, baud rate and number of units should be within the
values noted in the graph below.
Note3) The settings of the baud rate switches on the side of the unit and the system register No. 415
should be the same. Only 19200 bps can be specified when the C-NET adapter is connected with
the RS485 interface.
Note4) The start code and end code can be used only in the general-purpose serial communication
mode.
Note5) Unit numbers should be registered by the system register.

Note:
As it is the non-isolated type, the potential difference between the power supplies of RS485 devices
should be 4 V or less. If it exceeds 4 V, the unit may not communicate. The large potential difference
leads to the damage to devices.
