Only the 16 LR words from LR 00 to LR 15 can be linked in the CPM1/CPM1A, so
use only those 16 words in the CQM1 or C200HS when making a 1:1 PC Link
with one of those PCs. A 1:1 PC Link cannot be made to a CPM1/CPM1A PC
using LR 16 through LR 63 in the CQM1 or C200HS.
The settings relating to 1:1 PC Link communications must be set as shown in the
following table.
