set as follows.

CNC has three channels of reader/punch interfaces. This CNC has three
channels of interfaces (reader/punch and remote buffer interfaces). It also
has a memory card interface. The input/output device to be used is
specified by setting the channel (interface) 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. (This is not necessary for the
memory card interface.)
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.
