Before an external input/output device can be used, parameters must be
set as follows.
CNC
MAIN CPU BOARD
Channel 1 Channel 2
JD36A JD36B
RS–232–CRS–232–C
Reader/
puncher

I/O CHANNEL=0
or
I/O CHANNEL=1
I/O CHANNEL=2
CNC has two channels of reader/punch interfaces. The CNC has a
memory card interface as well. 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. (No data need be set 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.
