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.
When using a baud rate of 300 bps to 38400 bps, you can set up to a maximum of 99 units
(stations) and maximum transmission distance of 1200 m.
Note3) Only 9600 bps or 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) The converter SI-35 manufactured by Lineeye Co., Ltd is recommendable for the RS485 at the
computer side. Adjust the response time for the FP-X by the SYS1 instruction if necessary.
Note6) Unit numbers should be registered by the system register.
Note7) The termination resistance of the RS485/RS422 in the COM3,COM4 and COM6 is specified by
the dip switch in the communication cassette.
There is no termination resistance at the RS232C port.
