The maximum baud rate when CS or RS control wires are wrapped at ends of the cable is 19,200 bps.

When CS or RS control wires and hardware flow control are being used, the maximum achievable baud rate is 38,400 bps in most cases.

When, for example, using a baud rate of 56,000 or 115,200 bps on a laptop computer with the CX-Programmer FA Integrated Tool Package, the hardware chipset, Windows version, installed drivers and application software are all factors that may affect the system, causing stable operations at times and communications errors at other times.
