CNC has three channels of reader/punch interfaces. The input/output
device to be used is specified by setting the channel connected to that
device in setting parameter I/O CHANNEL.
The specified data, such as a baud rate and the number of stop bits, of an
input/output device connected to a specific channel must be set in
parameters for that channel in advance.
For channel 1, two combinations of parameters to specify the input/output
device data are provided.
The following shows the interrelation between the reader/punch interface
parameters for the channels.
