2 Transmission speed of 230400 bps is available for only CH1.
3 When connecting external devices to both of two interfaces, the total of the communication speed
should be 230400 bps of less. When connecting an external device to either of two interfaces, the
maximum of 115200 bps is available for the interface (a maximum of 230400 bps if using CH1
side)). In this case, set 300 bps for the other interface to which no external device is connected.
4 Set "00 " to the interface for which "GX Developer connection" is set in the communication
H
protocol setting. Serial communication module will operate at the communication speed set on
the GX Developer.
