Reference: When using the CX-Programmer to set the high-speed 1:N NT Link, set the com-
munications baud rate to 115,200 bps.
Setting the Front Switches
Set pins 4 and 5 of the CPU Unit DIP switch in accordance with the port that the
NT21 is connected to.
Peripheral port
This is used mainly for
connection to the
Programming Device.
(This also supports
connection of RS-232C
devices.)
