When making settings with the CX-Programmer, set the baud rate to
115,200 bps for a high-speed NT Link or 38,400 bps for a standard NT Link.
The following table shows the corresponding settings when using a Program-
ming Console.

Set the PT as follows:
1. Select NT Link (1:N) from Comm. A Method or Comm. B Method on the
Memory Switch Menu under the System Menu on the PT Unit.
2. Press the SET Touch Switch to set the Comm. Speed to High Speed.
FINS messages (commands) that are received are automatically converted
into the specified protocol and then sent via serial communications. The
responses are also automatically converted. When the CPU Unit's RS-232C
port or peripheral port is used, FINS messages can be converted into the fol-
lowing protocol.
• CompoWay/F
The Serial Gateway is enabled when the serial communications mode is set
